Description
Digital Fabrication has played a pivotal role in providing reality to industrial designers' ideas since its first commercial use in late 80's. Making the final prototype of a design project has been the initial assumed use for these technologies in the design process. However, new technology advances in this area offer further opportunities for designers. In this research these opportunities have been carefully explored. This research will be conceptualized through discussing the findings of a case study and theories in the areas of Industrial Design methodology, digital fabrication, and design pedagogy. Considering the span of digital fabrication capabilities, this research intends to look into the design-fabrication relation from a methodology perspective and attempts to answer the question of how the digital fabrication methods can be integrated into the Industrial Design process to increase the tangibility of the design process in very first steps. It will be argued that the above is achievable in certain design topics - i.e. those with known components but unknown architecture. This will be studied through the development of series of hypothetical design processes emphasizing the role of digital fabrication as an ideation tool rather than a presentation tool. In this case study, two differing processes have been developed and given to Industrial Design students to design specific power tools. One of them is developed based on the precedence of digital fabrication. Then the outcome of the two processes is compared and evaluated. This research will introduce the advantages of using the digital fabrication techniques as a powerful ideation tool, which overcomes the imagination problems in many of complicated design topics. More importantly, this study suggests the criteria of selecting the proposed design methodology. It is hoped that these findings along with the advances in the area of additive and subtractive fabrication will assist industrial designers to create unique methodologies to deal with complicated needs both in practice and design education.

Description
All too often, industrial designers face seemingly intractable obstacles as they endeavor to, as Simon (1996, p. 111) describes, devise "courses of action aimed at changing existing situations into preferred ones." These problems, described by Rittel and Webber (1973) as "wicked," are insurmountable due to the contradictory and changing nature of their requirements. I argue that that industrial design (ID) is largely subject to Rittel's quandary because of its penchant for producing single solutions for large populations; such design solutions are bound, in some senses, to fail due to the contradictory and changing nature of large and, thus, inherently diverse populations. This one-size-fits-all approach is not a necessary attribute of ID, rather, it is a consequence of the time in which it came into being, specifically, the period of industrial mass production. Fortunately, new, agile manufacturing techniques, inexpensive sensors, and machine learning provide an alternative course for ID to take, but it requires a new way of thinking and it requires a new set of methods, which I will elaborate in this thesis. According to Duguay, Landry, and Pasin (1997), we are entering an age where it will be feasible to produce individualized, one-off products from large-scale industrial manufacturing facilities in a way that is not only cost effective, but in many ways as cost effective as the existing techniques of mass production. By availing ourselves of these opportunities, we can tame the problem, not by defeating Rittel's logic, rather by reducing the extent to which his theories are appropriate to the domain of ID. This thesis also describes a test study: an experiment whose design was guided by the proposed design methodologies. The goal of the experiment was to determine the feasibility of a noninvasive system for measuring the health of the forearm muscles. Such a tool would provide the basis for assessing the true impact and possible pathogeny of the manual use of products or modifications to products. Previously, it was considered impossible to use surface electromyography (as opposed to needle or wire based electromyography) to assess muscular activity and muscular health due to the complexity of the arrangement of muscles in the forearm. Attempts to overcome this problem have failed because they have tried to create a single solution for all people. My hypothesis is that, by designing for each individual, a solution may be found. Specifically, I show that, for any given individual, there is a high correlation between the EMG signal and the movements of the fingers that, ostensibly, those muscles control. In other words, by knowing, with great accuracy, the position and the motion of the hand then it would become possible to disambiguate the mixed signals coming from the complex web of muscles in the forearm and enable the assessment of the forearm's health by non-invasive means.

Description
Industrial design is the practice of creating solutions by studying people and businesses. Originally centered on development of goods, industrial design uses methods rooted in human behavioral study, human factors, and strategic problem solving. As our economy and professional practice shift away from manufacturing towards a service-dominant landscape, industrial design must align its profession to formally include service design. The small service business setting is a microcosm in which the value of design and branding in business is magnified. This research reinforces design's ties with services marketing and business and is dedicated to finding solutions for the backbone of our economy. Micro-businesses with fewer than 20 employees often lack the sophisticated management, marketing, and strategies that bring about success. Despite the fact that 70% to 80% of small and micro businesses are service based, little research is dedicated to unique strategies for these small service firms. Research has shown that using strategic business design increases small business success. Given high small business failure rates, it behooves entrepreneurs to use intuitive planning tools that are appropriate for the dynamic startup years. When put within reach and context of small business owners, the tools used in design draw a clear map of insights into the "design" of small businesses. Through a literature review, interviews, and a new workshop method, the needs of small business owners and the challenges they face are used to design and implement an accessible, actionable strategic toolkit for small service businesses. This simple, interdisciplinary toolkit was designed with the goal of increasing the efficacy and likelihood of ongoing strategic business planning through context-specific, instrumental activities. The tools are shown to help a business owner form pragmatic, iterative problem-solving approaches that allow the business owner to plan in the face of uncertainty and find insights into her own business, brand, and services.

Description
In geographical locations with hot-arid climates, sun control in buildings is one primary problem to solve for the building envelope design. Today's technological advances in building science bring with them the opportunity to design dynamic façade systems for sun radiation control and daylighting. Although dynamic systems can become an attractive visual element, they can be costly and challenging to maintain for building owners. Alternatively, fixed solar-shading systems can be designed to create dynamism in the façade of the building, while providing similar functionalities for sun control. The work presented in this project focuses on the use of a visual scripting editor for modeling software, Grasshopper, to develop a Solar Control Visual Script that evaluates building envelope surfaces with planar and non-uniform rational basis-spline (NURBS) forms and provides projections for fixed sun control systems. The design platform of Grasshopper allows individuals with no experience or prior computer coding education to build up programming-like capabilities; this feature permits users to discover new design possibilities within flexible frames that can contribute to the overall design being pursued, while also having an environmental response. The Solar Control Visual Script provides minimum sizing geometries that achieve shading in openings at a particular date and time of the year. The model for this method of analysis makes use of three components to derive the appropriate values for the projections of shading geometries: typical meteorological year (TMY) data, irradiation isotropic equations and shading profile angles equations for vertical and tilted surfaces. Providing an automatic visual of generated geometries uncovers the opportunity to test several model forms and reiterates the analysis when modifying control parameters. By employing building science as a set of environmental parameters, the design outcome bears a dynamic form that responds to natural force conditions. The optimized results promote an efficient environmental design solution for sun control as an integral alternative into the building envelope.

Description
The main objective of this project was to create a framework for holistic ideation and investigate the technical issues involved in its implementation. In previous research, logical ideation methods were explored, ideation states were identified, and tentative set of ideation blocks with strategies were incorporated in an interactive software testbed. As a subsequent study, in this research, intuitive methods and their strategies were investigated and characterized, a framework to organize the components of ideation (both logical and intuitive) was devised, and different ideation methods were implemented based on the framework. One of the major contributions of this research is the method by which information passes between different ideation methods. Another important part of the research is that a framework to organize ideas found by different methods. The intuitive ideation strategies added to the holistic test bed are reframing, restructuring, random connection, force connection, and analogical reasoning. A computer tool facilitating holistic ideation was developed. This framework can also be used as a research tool to collect large amounts of data from designers about their choice of ideation strategies, and assessment of their effectiveness.

Description
Due to the lack of understanding of soil thermal behavior, rules-of-thumb and generalized procedures are typically used to guide building professionals in the design of ground coupled heat pump systems. This is especially true when sizing the ground heat exchanger (GHE) loop. Unfortunately, these generalized procedures often encourage building engineers to adopt a conservative design approach resulting in the gross over-sizing of the GHE, thus drastically increasing their installation cost. This conservative design approach is particularly prevalent for buildings located in hot and arid climates, where the soils are often granular and where the water table tends to exist deep below the soil surface. These adverse soil conditions reduce the heat dissipation efficiency of the GHE and have hindered the adoption of ground coupled heat pump systems in such climates. During cooling mode operation, heat is extracted from the building and rejected into the ground via the GHE. Prolonged heat dissipation into the ground can result in a coupled flow of both heat and moisture, causing the moisture to migrate away from the GHE piping. This coupled flow phenomenon causes the soil near the GHE to dry out and results in the degradation of the GHE heat dissipation capacity. Although relatively simple techniques of backfilling the GHE have been used in practice to mitigate such coupled effects, methods of improving the thermal behavior of the backfill region around the GHE, especially in horizontal systems, have not been extensively studied. This thesis presents an experimental study of heat dissipation from a horizontal GHE, buried in two backfill materials: (1) dry sand, and (2) wax-sand composite mixture. The HYDRUS software was then used to numerically model the temperature profiles associated with the aforementioned backfill conditions, and the influence of the contact resistance at the GHE-backfill interface was studied. The modeling strategy developed in HYDRUS was proven to be adequate in predicting the thermal performance of GHE buried in dry sand. However, when predicting the GHE heat dissipation in the wax-sand backfill, significant discrepancies between model prediction and experimental results still exist even after calibrating the model by including a term for the contact resistance. Overall, the thermal properties of the backfill were determined to be a key determinant of the GHE heat dissipation capacity. In particular, the wax-sand backfill was estimated to dissipate 50-60% more heat than dry sand backfill.

Description
Individuals' experiences, environment, and education greatly impact their entire being. Similarly, a designer is affected by these elements, which impacts how, what and why they design. In order for design education to generate designers who are more socially aware problem solvers, that education must introduce complex social matters and not just design skills. Traditionally designers learned through apprenticing a master. Most design education has moved away from this traditional model and has begun incorporating a well-rounded program of study, yet there are still more improvements to be made. This research proposes a new Integrated Transformational Experience Model, ITEM, for design education which will be rooted in sustainability, cultural integration, social embeddedness, and discipline collaboration. The designer will be introduced to new ideas and experiences from the immersion of current social issues where they will gain experience creating solutions to global problems enabling them to become catalysts of change. This research is based on interviews with industrial design students to gain insights, benefits and drawbacks of the current model of design education. This research will expand on the current model for design education, combining new ideas that will shed light on the future of design disciplines through the education and motivation of designers. The desired outcome of this study is to incorporate hands on learning through social issues in design classrooms, identify ways to educate future problem solvers, and inspire more research on this issue.

Description
Despite the various driver assistance systems and electronics, the threat to life of driver, passengers and other people on the road still persists. With the growth in technology, the use of in-vehicle devices with a plethora of buttons and features is increasing resulting in increased distraction. Recently, speech recognition has emerged as an alternative to distraction and has the potential to be beneficial. However, considering the fact that automotive environment is dynamic and noisy in nature, distraction may not arise from the manual interaction, but due to the cognitive load. Hence, speech recognition certainly cannot be a reliable mode of communication.
The thesis is focused on proposing a simultaneous multimodal approach for designing interface between driver and vehicle with a goal to enable the driver to be more attentive to the driving tasks and spend less time fiddling with distractive tasks. By analyzing the human-human multimodal interaction techniques, new modes have been identified and experimented, especially suitable for the automotive context. The identified modes are touch, speech, graphics, voice-tip and text-tip. The multiple modes are intended to work collectively to make the interaction more intuitive and natural. In order to obtain a minimalist user-centered design for the center stack, various design principles such as 80/20 rule, contour bias, affordance, flexibility-usability trade-off etc. have been implemented on the prototypes. The prototype was developed using the Dragon software development kit on android platform for speech recognition.
In the present study, the driver behavior was investigated in an experiment conducted on the DriveSafety driving simulator DS-600s. Twelve volunteers drove the simulator under two conditions: (1) accessing the center stack applications using touch only and (2) accessing the applications using speech with offered text-tip. The duration for which user looked away from the road (eyes-off-road) was measured manually for each scenario. Comparison of results proved that eyes-off-road time is less for the second scenario. The minimalist design with 8-10 icons per screen proved to be effective as all the readings were within the driver distraction recommendations (eyes-off-road time < 2sec per screen) defined by NHTSA.

Description
A post occupancy evaluation (POE) was conducted at the Ngeruka Health Center (NHC) in the Bugesera District of Rwanda. The POE was limited to the education spaces within the health center, its participants, and staff. A POE is a combination of methods both quantitative and qualitative to determine user satisfaction and whether the design intent of the built environment was met.
In rural Rwanda where healthcare facilities are scarce and people become seriously ill from preventable diseases, help is needed. The smallest injuries become life threatening. Healthcare facilities and providers must develop approaches that stop these minor illnesses and diseases from costing further problems.
The healthcare facility is a healing environment. Healing environments nurture health and provide a sense of safety and security. The Ngeruka facility has incorporated education spaces within their facility to teach the community ways to prevent minor health problems from becoming major ones.
The research that was conducted at this healthcare facility sought to answer the main questions: Does the built environment of the NHC contribute to healing by engaging education program attendees to learn about preventing illness and disease and other health promotion strategies? In addition, can you measure healing effects of the built environment?
The research took measurements of the built environment and combined them with user satisfaction questionnaires. Site observations and a participant engagement questionnaire were used to determine the amount of engagement the participants put forth into the education programs within the designated design space. Measuring engagement is a tool schools use to find out if their facilities are producing their intended results. This same thought process was incorporated into this research. The participants did prove to be engaged, but it is not definitive that the built environment was responsible. It was a combination of many factors.

Description
The humans-food relationship is a 2.5 million year old, symbiotic connection of “living together” which encouraged a “system of communication up and down the food chain” (Pollan, 2008). (Reardon, 2015). Many researchers agree that this connection is a critical foundation for a beneficial relationship with food and engaging in healthy eating behaviors (McKeown, 2010; Neumark-Stainer et al., 2007; Ristovski-Slejepcevic et al., 2008; Simontacchi, 2007). Against the backdrop of a steadily increasing obesity rate and associated spending, it is critical to approach this issue from a systematic perspective such as understanding the powers that impact the consumer-food relationship (Aronne and Havas, 2009). Experts agree that the rapid increase in convenience food environments has contributed to an obesogenic foodscape that has negatively impacted consumers’ understanding of and interactions with food, resulting in consumption of nutritionally poor food, over-nutrition and chronic illness (Brownell and Battle-Horgen, 2004; Nestle, 2002). Additionally, designers and researchers are beginning to recognize the influence the built environment can have on actions (Patel, 2012; Wansink, 2010), behaviors and attitudes (Gallagher, 1993), even hindering or encouraging one to partake in healthy behaviors (Mikkelsen, 2011; Story et al., 2008). The goal of this study is to understand modern built convenience food environment design and its potential to impact the consumer-food relationship. This study utilizes a heavily qualitative approach, structured by a grounded theory methodology due to the lack of existing research (Martin & Hanington, 2012; O’Leary, 2010) and triangulates utilizing an analysis of secondary research, environmental audit through observations and a survey. The final result will be a compilation of design suggestions, based on those findings, for designing a BCCFE that encourages a healthy relationship between the consumer and food.
