  • 1. Benzenberg, Elizabeth Exploring Design Process Evolution in Architecture and Interior Design Firms

    Master of Fine Arts, The Ohio State University, 2011, Industrial, Interior Visual Communication Design

    Architects and interior designers must work together and with others on the design team in a series of processes in order for the building projects they undertake to be successful. The two major processes that they go through are the creative decision-making process as well as the project timeline and process. These two processes must be able to work within one another in order to produce a successful outcome. Along with changes in the creative decision-making and the project processes, two shifts are taking place in how architects and interior designers bureaucratically manage a project. The first is a shift in the type of technology used to share concepts and document design. The second is a shift in project management that begins to include the client (and other stakeholders) earlier in the process, thus increasing the size of the design team. These two shifts have a great affect on one another and are continuously co-evolving. This thesis first defines processes historically used in the architecture and interior design professions through secondary research and a literature review. These discipline specific processes are compared and contrasted with processes gathered from general design and related disciplines such as engineering design, product design, and software design. Second, this thesis documents primary research (in the form of interviews), which seeks to identify processes that currently utilize new technologies and expanded project team within the architecture and interior design profession. In summary, the results are analyzed, compared to secondary research, and a new process is suggested as the next step in the evolution of the design process.

  • 2. O'Brien, Erin An Analysis of Designer Problem-Solving in Addressing Overconsumption of Clothing

    MFIS, Kent State University, 2020, College of the Arts / School of Fashion

    Driven by fast fashion and overconsumption of clothing, the fashion industry is one of the largest polluters in the world. The purpose of this research was to explore the creative process of fashion designers in pursuit of a deeper understanding of creative problem-solving specific to fashion design as well as an effort to gain insight into pragmatic solutions for addressing the sustainability issue of overconsumption of clothing. This qualitative research examined the complex creative processes of three professional fashion designers with a minimum of thirteen years of experience. Utilizing open-ended, one-on-one interviews, participant data was recorded, transcribed and analyzed to identify emerging themes and patterns. A case study research design was used to present the findings. This study revealed that fashion designers specifically are crucial to finding sustainable solutions in changing the way the fashion industry operates. However, analysis also showed that overconsumption of clothing is a systemic problem which affects the whole fashion production model. Addressing overconsumption in the fashion industry includes a number of different facets, that include, but go substantially beyond design. In order to move away from the fast fashion model, change is required from both fashion professionals and consumers. The findings of this study add to the existing knowledge of design research and the creative process of professional fashion designers centered around problem-solving, experience, communication, customer, creative space and sources of inspiration. Furthermore, this study helps extend the knowledge of the complex issue of incorporating sustainable practices into the fashion industry by examining the challenges such as cost, thinking fabric first, continuous questions and profit as a goal.

  • 3. Moss, Tracy Reframing Integrated Operations as Design Process

    MDES, University of Cincinnati, 2020, Design, Architecture, Art and Planning: Design

    As the U.S. Department of Defense attempts to transform its modus operandi for conducting global operations in an increasingly complex, dynamic environment, the Joint Chiefs of Staff have released a Joint Concept for Integrated Campaigning (JCIC). The concept introduces a framework that broadly describes how the military and its partners can effectively campaign in support of national security interests. This paper will explore the idea that the JCIC framework represents a design process by comparing the JCIC framework to a generalized design process.

  • 4. Burns, Mikaila Mapping the Gap: Using Growth Opportunity Items and Principles as well as Design Thinking to Eliminate the Creative Achievement Gap

    Master of Fine Arts, The Ohio State University, 2014, Industrial, Interior Visual Communication Design

    The Skills Gap is a disconnect in the skills that students have acquired throughout their education, and the skills that businesses are seeking from potential employees. The Creativity Crisis is the documented phenomenon where young children test at genius levels of creativity, but by adulthood, lose most of their creative capacity. Until now, these two ideas have been considered separate circumstances, but what if they are part of a bigger problem…of a Creative Achievement Gap? While students continue to lose creativity, businesses demand innovative, creative thinkers. Design Thinking can help to bridge the gap. Using existing research and literature, I have uncovered five separate Growth Opportunities that will help to align the goals of K–12 education, business, and learners (of any age). These Growth Opportunities are Skills, Character, Mindset, Values, and Community. Items in each individual Growth Opportunity have been communicated by authors from many different backgrounds, and writings about a variety of topics (education, business, design, thinking, creativity, etc). In the end, I will propose a list of “Shared Principles for Stakeholder Alignment” which are the Growth Opportunity items that I've interpreted as actionable principles that can be used to align all stakeholder groups—students, parents, teachers, workers, businesses, and learners of any age. By doing so, we can effectively address the Creative Achievement Gap.

  • 5. Jaspart, Marie Emergence in Vehicle Design: Using the Concept of Emergence to Provide a New Perspective on the Creative Phases of the Automobile Design Process

    MDes, University of Cincinnati, 2010, Design, Architecture, Art and Planning : Design

    Beauty, usefulness, desirability, low-cost, power, and sustainability are some of the numerous ideals that make the design of a vehicle complex and challenging. The understanding of emergence, a fundamental creative process originally found in natural systems, might provide insight for the stakeholders in the vehicle design process who wish to create innovative solutions. In this study, an exploration of this notion in design is presented, with specific examples for car design. The principles set forth by Johnson for building a system with adaptability and macro-intelligence, are analyzed. Then, several methods for implementing these principles in the car design team are suggested, along with a strategy for facilitating the emergence of innovative vehicle designs in the context of the car industry.

  • 6. Sen, Amrita Systems modeling, analysis, design and roadmapping of the global chemicals and materials industry towards an economical transition to sustainability, circularity, and net-zero emissions

    Doctor of Philosophy, The Ohio State University, 2024, Chemical Engineering

    The ill effects of climate change are unfolding in real time, as species and ecosystems face irreversible destruction. Climate action is needed now more than ever, as ambitious targets set by the Paris Agreement seem far-reaching in the wake of global average temperatures above 1.5C over their pre-industrial levels recorded over a continuous 12 month period for the first time. Countries, organizations, and companies alike have pledged to limit their net greenhouse gas (GHG) emissions to the environment to zero, via nationally determined contributions and corporate net-zero commitments. Such commitments remain unattainable in the absence of guidance like convergent carbon accounting methods, systems models, and roadmapping frameworks. This dissertation seeks to bridge this gap for the chemicals and materials industry (CMI). The chemical industry generates the “hardest to abate” emissions among the industrial sector due to the fixed carbon content of its products. However, as chemical energy carriers such as hydrogen and methanol gain prominence as solutions to the intermittency issues of renewable energy, the net-zero transition of chemicals becomes tied to the net-zero goals of more expansive and ubiquitous industries such as the power sector. The decarbonization of chemicals to this end, requires estimation of material and carbon flows, and baseline emissions of its current global operations. The frameworks in literature lack appropriate structure and comprehensiveness for such analysis, and relevant process and price data are inaccessible and cost prohibitive. We therefore develop an inventory of first principle based, mass balance compliant, publicly available process and cost data for CMI processes, sourced from the public domain. We devise a regression framework capable of handling conflict ridden data, and an algorithm to map resource, intermediate, product, and emission flows of any chemical system with known product capacities.

  • 7. Jha, Smriti Systematic Feature Extraction and Feature-based Manufacturing Process Selection for Hybrid Manufacturing

    MS, University of Cincinnati, 2022, Engineering and Applied Science: Mechanical Engineering

    With so many different manufacturing processes around, the industry has started combining different processes to combine their respective advantages and counter the disadvantages. Hybrid manufacturing processes, a combination of additive and subtractive methods, are being explored to increase the overall efficiency and part quality. There is a need for the selection of the optimal set of processes based on the part geometry and part material. The part features, in turn, directly affect the selection of the optimal sequence of processes. This thesis explores the idea of evaluating the STL models of a part based on Design for Manufacturing (DFM) and Design for Additive Manufacturing (DfAM) rules to select the optimal combination of subtractive and additive processes for manufacturing the part. The metrics are extracted directly from the features of the STL model by performing a slice-by-slice analysis of the part to determine the combinations of the geometric demarcation point between various processes. For additive processes, the list of metrics extracted includes the volume of material to be added, staircase error, sharp corner, and support structure volume. The metrics considered for subtractive processes are the volume of material removal, tool inaccessibility, part geometry complexity, and sharp internal corners that may be difficult to machine. For each part geometry and build orientation, the overall final score is calculated for subtractive and additive process metrics, and a decision is made on the optimal combination and demarcation points for using the various processes for manufacturing the part. Several case studies of varying complexity have been presented for calculating the metrics and determining the optimal process plans.

  • 8. Obeidat, Nawar The Design and Development Process for Hardware/Software Embedded Systems: Example Systems and Tutorials

    MS, University of Cincinnati, 2014, Engineering and Applied Science: Computer Engineering

    Today embedded systems are found in all areas of our lives and have many different applications. They differ in their uses and properties as well as employing both software and hardware components in their implementations. This has made the design and development process for them much more complicated. Learning to use such a process is especially difficult for electrical engineering students, who have not been introduced to the systematic design and testing methodologies familiar to students trained in computer science and computer engineering. In this thesis, we illustrate the similarities and differences in the design and development design processes in for software systems and for software/hardware embedded systems. We give details for every stage for both types of systems and we develop detailed examples for example embedded systems, using a design process which extends the standard UML-based process used for software. In addition, we include details about project management. The examples and additional exercises and questions provide a set of tutorials which will assist students unfamiliar with complex design procedures in mastering the necessary skills to become well-trained embedded system developers.

  • 9. Abraham, Thomas Kinetic bounds on attainability in the reactor synthesis problem

    Doctor of Philosophy, The Ohio State University, 2005, Chemical Engineering

    For a given chemical reaction network with known kinetics, a specified feed composition, and specific process constraints, the attainable region for the reactor synthesis problem is the set of all composition vectors that are achievable through all constraint-consistent reactor configurations that invoke only reaction and mixing. The boundary of the attainable region gives useful information to a process designer in terms of yield and selectivity of a desired chemical species that might be achieved by any constraint-consistent design. Though much is known about necessary conditions for compositions to lie on the boundary of the attainable region, a definite method to calculate the true boundary of the attainable region is not known. Most of the existing methods compute “candidate” attainable regions by starting at the feed composition and attempt to enlarge the set of attainable compositions by considering various reactor configurations until no further enlargement is seen. These methods raise the question of whether the “candidate” attainable region has come close to the (currently unknown) true attainable region. These methods cannot preclude with certainty the existence of some novel reactor configuration that can enlarge the current set of achievable compositions. This thesis describes a new technique called the method of bounding hyperplanes that complements existing methods by “bounding from the outside” those composition vectors that are attainable. In other words, the method seeks to create a set of composition vectors such that all composition vectors lying outside this set are inaccessible from the feed. Thus, the true attainable region will be contained in or will coincide within the bounding set so created. The kinetic bounds do well in precluding a large set of compositions that would otherwise be considered feasible from stoichiometric considerations alone. In many instances, the computed bounds are sharp insofar as they come very close to compositions (open full item for complete abstract)

  • 10. Bui, Domagoj Full Inclusive Participation: Design Process Case Study in Urban Mobility

    MDES, University of Cincinnati, 2024, Design, Architecture, Art and Planning: Design

    American cities and their mobility options often exclude many groups and individuals. This is an issue because mobility can create disabilities and amplify social factors of exclusion, resulting in larger societal problems. Urban mobility not being inclusive is connected to the design process not being inclusive. Inclusive design can bridge the gaps by considering a wider range of human diversity. However, designers and organizations often overlook or dismiss specialized inclusive methods due to concerns about resources and efficiency. This research proposes a full inclusive participatory approach to urban mobility design, combining conventional design methods and the participation of exclusion expert users, users from groups who experience exclusion named to emphasize their equity with designers, throughout the design process. This is studied through a case study comparing a designer group and a participatory group with designers and people with visual impairments working equitably together. Both groups worked on a mobility design solution for the Cincinnati Metro bus service. To provide valuable insights for designers specifically, the design process was captured, participants were interviewed throughout the design process, and mobility design experts evaluated the final solutions of both groups. Designers involved in the participatory group recognize the value of the approach in learning, inclusivity, and productivity, and want to advocate for it. Experts state that the approach could yield more inclusive products and improved implementation if the work on the project continued. To conclude, the benefits the approach brings to designers in the form of knowledge and awareness, to the process in terms of increased inclusivity while retaining efficiency and productivity, and to the solutions in higher inclusivity and resource feasibility outweigh the challenges of having team leaders prepare more upfront and organizations to community outreach.

  • 11. Tewani, Priyanka Joint Activity Design (JAD) to support design for joint activity and the joint activity of design: an analysis of barriers and facilitators

    Master of Science, The Ohio State University, 2023, Industrial and Systems Engineering

    As automation and technology has grown, machines are no longer tools and new human-machine architectures have emerged that move beyond the definition of a traditional team and are better defined through joint activity. Current design philosophies, such as Human-Centered Design (HCD), continue to look at systems as collections of components, which is insufficient to understand the interdependencies and complexities that are necessary to support these new work architectures. Joint activity design (JAD) has been introduced to fill this gap and explicitly design for joint activity. However, adoption of JAD and similar techniques has been slow, and it is unclear what factors are contributing to this lack of proliferation. In this study, we aimed to determine the challenges for implementation of JAD artifacts and what may have facilitated their use. By analyzing 5 case studies of design projects that span multiple organizations, we found that JAD artifacts were rarely used as intended due to a high cost and a high uncertainty on how to implement them. Whereas these artifacts were often used within smaller subunits, they were rarely used across the larger design function. Across the larger design function, the support was not sufficient to maintain common ground, which exacerbated many of the challenges that resulted in sacrificing the final design's ability to support joint activity. In the future it would be valuable to get a larger selection of cases from other organizations and more evidence needs to be collected on the value of JAD methods over HCD methods.

  • 12. Reeling, Hunter Aligning Functional Analysis Processes with Designers' Natural Cognitive Flow

    Master of Science, Miami University, 2023, Mechanical and Manufacturing Engineering

    Balancing creativity with a structured approach in engineering design poses a critical challenge, necessitating optimization of each stage to aid in efficiently creating superior products. Functional analysis, a systematic approach defining the design problem, enables comprehensive exploration of the design space. However, critics argue that it requires too many resources, restricts creativity, and imposes high demands on design teams. The goal of this research is to enhance the effectiveness of functional analysis by integrating theories from cognitive research and human-centered design. The proposed method, Natural Cognitive Flow Functional Analysis (NCFFA), aims to promote designers' creative freedom, maintain the quality of the function model, and be accessible to engineering students and professionals alike. A between-subject study involving novice engineers evaluated the effectiveness of NCFFA. Although determining the full effectiveness of NCFFA in terms of enhanced creativity and reduced effort proved challenging, the study found marginal improvement in designers' Flow State, suggesting the potential merit of the NCFFA method for enhancing the designer experience during functional analysis. The study highlights the benefits of incorporating cognitive research and human-centered design principles into functional analysis and paves the way for further research to refine the structured design process.

  • 13. Hightower, Jessica The Country Wife: A Scenic Design Process

    Master of Fine Arts, The Ohio State University, 2023, Theatre

    Performance is used as a means of storytelling, to escape, to reflect, to learn, to celebrate, or to understand other perspectives. The Country Wife by William Wycherley is all of the above. It is a multi-faceted script that Wycherley curated to appeal to the masses. Written in 1675, this Restoration play uses wit and comedy to comment on societal structures such as gender norms, class, rank, and relationships. The narrative is funny, raunchy, clever, pointed, self-reflective, and opens itself up to be consumed at a variety of levels. I designed the scenery for the 2022 production at The Ohio State University. This is the detailed analysis of that process.

  • 14. Sabatelli, Madison Navigating the Design Process Through Writing: An Ethnographic Study of Academic Design Studios

    Master of Fine Arts, The Ohio State University, 2020, Design

    The ways thoughts are externalized is a difficult one met with many choices, first and foremost being the mode in which an idea is conveyed. While design is often thought of as visual fields defined by renderings, models, and sketches, the use of writing can be just as pertinent and necessary. This thesis sparks an investigation into how design students use writing to effectively move through the design process. Utilizing an ethnographic approach, this study examines three interdisciplinary design studios at The Ohio State University, one at the beginner level and two at the advanced level. Classroom observations of students at work, informal chats and formal interviews with key participants, and documentation of students' process work (notes, sketches, models, and other forms of documentation used to inform a final design) all serve to paint a complete picture of the manner in which writing is used in design education. These varied means of data gathering serve to create a corpus that references the many ways in which students use writing as a part of the design process. Understanding designers' writing aims to inform better ways of designing, suggest how to effectively communicate across disciplines, and aid in formulating a process for formally incorporating writing in design education and practice. By reflecting on a compilation of student writing practices, this study presents the modes in which we communicate design textually while reconsidering the possibility for new ones that incorporate interdisciplinary values and verbiage.

  • 15. Nickley, William Making for One Another: An Exploration of Design-based Making in Positive Youth Development Program Delivery

    Master of Fine Arts, The Ohio State University, 2020, Design

    This research examines how design-based making strategically supports the outcomes of Positive Youth Development (PYD) programs. PYD is understood as a developmental process, an approach to youth programming, and as instances of youth programs and organizations focused on fostering the positive development of youth by engaging youth within their communities, schools, organizations, peer groups and families in a constructive manner. While a review of the literature revealed PYD successfully mobilizes other types of making in its programming (arts-based, sciences-based, etc.), it remains blind to the avenues and opportunities offered by design-based making. Through a pilot test of a PYD program, this research examines how design-based making might provide opportunities within PYD programming to support and foster PYD objectives. The study was designed and conducted to capture youth experiences during a six-week out-of-school PYD program at a Boys & Girls Clubs of Columbus location (Ohio). Youth experiences were analyzed through inductive and deductive thematic analyses, which resulted in eight emergent sub-themes organized under two main themes: A Design Journey is Personal; and Design Facilitates an Emergent Network of Contribution. Each theme revealed aspects of how design-based making supports PYD program outcomes. The research concludes with a roadmap for future research and practice to further connect the domains of Design and PYD.

  • 16. Sanchez, Norberto Designing Engagement: A Method for improving Multisensorial Properties of Products

    MDES, University of Cincinnati, 2019, Design, Architecture, Art and Planning: Design

    The adoption of a medical device represents a challenge for new users. Beyond their function, medical objects communicate on behalf of the user. The people around the user interpret the messages transmitted by the object and create views and stigmas toward the product and the user. These situations complicate the already challenging position of older adults. Like medical products, objects oriented for older adults neglect the users' needs and force them to accept a product that ignores their values and identities on behalf of convenience and safety. These circumstances urge industrial design to address the absence of product engagement for a growing population of older adults, especially when the product possesses a complex social meaning that impacts the user's wellbeing, such as medical devices. Industrial design has neglected the necessity of good medical design, medical products are traditionally designed to be reliable, safe to use, efficient, and profitable leaving aside the phycological, social, and emotional needs of the user. This thesis proposes a design method based on semantic attribution and its relationship with object materiality. The method aims to promote product adoption, by using the multisensorial properties of the object to encode semantic attributes that align with the user identities. This thesis explores the inclusion of virtual reality as an assistive platform for the methodology. A series of studies were conducted to evaluate the method and its incorporation into the design process. Initial findings generate: a refined analysis tool; evidence of converging results on the product interventions despite the experience or background of the participants; and evidence of the manifestation of behavioral patterns between designers and users.

  • 17. Kellert, Heather Mining and Crafting Mathematics: Designing a Model for Embedding Educational Tasks in Video Games

    Doctor of Philosophy, The Ohio State University, 2018, EDU Teaching and Learning

    The purpose of this study is to investigate the design and modification of a rich mathematical task embedded in an educational video game Minecraft through analysis of observations of student engagement in mathematical practices. Student engagement in both the game and the overarching task is framed using the application of Self-Determination Theory to video games (Przybylsky, Ryan & Rigby, 2010) while analysis of the researcher-teacher's design, implementation, and modification is framed through an iterative design process. Results of this qualitative study include multiple modifications of the researcher-teacher in attempt to enhance engagement in the Standards of Mathematical Practice (Common Core Standards State Initiative, 2018). The design and modifications of the task were then fit into a model to depict the relationships between four categories of student engagement including (1) engagement with the game, (2) engagement with mathematics, (3) engagement possibly motivated by factors of Self-Determination Theory, and (4) the task's ability to provide opportunities for students to engage in Standards for Mathematical Practice (Common Core State Standards Initiative, 2018).

  • 18. Montoya, Amanda Conditional Process Analysis in Two-Instance Repeated-Measures Designs

    Doctor of Philosophy, The Ohio State University, 2018, Psychology

    Conditional process models are commonly used in many areas of psychology research as well as research in other academic fields (e.g., marketing, communication, and education). Conditional process models combine mediation analysis and moderation analysis. Mediation analysis, sometimes called process analysis, investigates if an independent variable influences an outcome variable through a specific intermediary variable, sometimes called a mediator. Moderation analysis investigates if the relationship between two variables depends on another. Conditional process models are very popular because they allow us to better understand how the processes we are interested in might vary depending on characteristics of different individuals, situations, and other moderating variables. Methodological developments in conditional process analysis have primarily focused on the analysis of data collected using between-subjects experimental designs or cross-sectional designs. However, another very common design is the two-instance repeated-measures design. A two-instance repeated-measures design is one where each subject is measured twice; once in each of two instances. In the analysis discussed in this dissertation, the factor that differentiates the two repeated measurements is the independent variable of interest. Research on how to statistically test mediation, moderation, and conditional process models in these designs has been minimal. Judd, Kenny, and McClelland (2001) introduced a piecewise method for testing for mediation, reminiscent of the Baron and Kenny causal steps approach for between-participant designs. Montoya and Hayes (2017) took this piecewise approach and translated it to a path-analytic approach, allowing for a quantification of the indirect effect, more sophisticated methods of inference, and the extension to multiple mediator models. Moderation analysis in these designs has been described by Judd, McClelland, and Smith (1996), Judd et al. (2001), and Montoya (open full item for complete abstract)

  • 19. Jagani, Sandeepkumar Byproduct Management and Sustainability Performance: Theory and Practices of US Manufacturing Firms

    Doctor of Philosophy, University of Toledo, 2018, Manufacturing and Technology Management

    Manufacturing companies have been successful in increasing their productivity since the beginning of the industrial era.. However, in the course of production of goods to satisfy customer demand, production companies have, intentionally or unintentionally, produced emissions, effluents, and solid waste giving rise to a new problem. During the last couple of decades, companies have been putting ample efforts to reduce detrimental impacts on society and environment; while trying hard to keep up with their financial goals. Sustainability related objectives of companies and their realization of responsibility towards environment has enabled companies to make sustainability a part of their business framework. Building upon literature of Resource-Based View (RBV), Structure-Conduct-Performance Paradigm, and Transactional Cost Economics, this dissertation proposes a theatrical framework where the first step towards making sustainability a competitive advantage is to develop sustainability orientation by adopting clear policies urging environmental awareness, recognizing stakeholders' ecological requirements, and outlining responsible use of natural resources. Furthermore, to transform sustainability orientation into business processes, this dissertation suggests byproduct management practices, which can attain desired outcomes. Implementation of sustainable product design, sustainable process design and production are the results of the sustainability orientation. However, the ultimate aim for the manufacturing firms must be to become zero waste throughout its supply chain. It can be achieved by eliminating emissions, effluents and waste. Drawing upon the concepts of industrial ecology and cradle to cradle, this dissertation proposes that when companies attempt to manage waste within their supply chain and turn it into byproducts with commercial value, they end up performing better environmentally, socially, and economically. Additionally, this research also aims to exam (open full item for complete abstract)

  • 20. Lu, Tai-Hung A Guideline for Designing Habitual and Persuasive Systems

    MDES, University of Cincinnati, 2017, Design, Architecture, Art and Planning: Design

    For years, designers focused on styling, technology, and usability, but neglected to consider the users' motivation. This study not only introduces a new perspective for designers but also serves as a design tool to create or evaluate persuasive and habit- forming systems. This study provides a general guideline for developing persuasive and habit-forming systems by helping designers to discover consumers' motivations, pain points, and possible drivers that could persuade consumers. For designers, knowledge of persuasive and habit-forming design is important since they want consumers to use or purchase their products or services. However, in many situations, the design team fails to persuade their users because they lack the knowledge of persuasive and habit- forming design. Creating persuasive and habit-forming systems is complex, and it is full of restrictions. However, design based on a good understanding of persuasive and habit-forming systems can be very successful. Therefore, by understanding the relationship between users' motivations and behaviors, designers can produce a more fruitful and positive outcome for their users.
