Idea Generation Through Empathy: Reimagining the ‘Cognitive Walk through’Students in engineering are required to evaluate their products against user requirements, but often, these requirements are abstracted from the user or context of use, making it difficult for students to empathize with the eventual user of the product or system they are designing. In previous research, we have demonstrated the use of Design Heuristics to encourage divergencein ideation at initial stages of the design process. Design Heuristics—a tool based on award-winning products and design activities of engineers and product designers (e.g., Yilmaz &Siefert, 2011)—has been extensively validated through empirical studies, shown to increase ideation capacity and flexibility. Use of this method has been focused primarily on early stage ideation, with less support for students who are iterating on or evaluating more developed concepts. Our proposal focuses on extending the student’s understanding of the problem space by generating empathy with the end user and context. Through this empathetic positioning, the Design Heuristics method can be used to lead to a richer space for additional idea generation.Typical uses of Design Heuristics in an engineering classroom context (e.g., Daly, et al., 2012)have not been situated in the context of use, thus operating at a level of abstraction above the user, context, or sociocultural milieu. One of the more significant insights to come out of the design community is the importance of problematizing the context and a rich understanding of the user and importing that information back into the design process (Beyer & Holtzblatt, 1996;Young, 2008). So while ideating with ...

Industrial Design Conference Presentations, Posters and Proceedings

The Impact of Teaming and Problem Solving Style on Student Perceptions of Design Ideation Out comes The importance of idea generation (ideation) within the engineering design process is recognized in academic and industrial settings alike. The collaborative nature of engineering design is also well-established, with individuals of differing personalities, technical backgrounds, and levels of experience coming together to meet shared design objectives. Engineering educators routinely put students in design teams to complete both simple and complex projects, with the assessment of students’ individual differences becoming increasingly common. Our goal for this study was to explore the extent to which teaming ...

How do we define the problems that would allow for the most diverse solution space?The purpose of this study was to gain an understanding of how different contexts impacted the variety of solutions generated within the solution space, by a diverse group ...


Exploring The Effects Of Problem Framing On Solution Shifts: A Case Study, Samuelina M. Wright, Eli M. Rutgers, Shanna R. Daly, Kathryn W. Jablokow, Seda Yilmaz Jun 2015

Exploring The Effects Of Problem Framing On Solution Shifts: A Case Study, Samuelina M. Wright, Eli M. Rutgers, Shanna R. Daly, Kathryn W. Jablokow, Seda Yilmaz

Industrial Design Conference Presentations, Posters and Proceedings

Exploring the Effects of Problem Framing on Solution Shifts: A Case Analysis Both students in engineering and practicing engineers are continually challenged with new problems to solve. We propose that the way the problem is presented will influence the engineer’s ideation processes, and eventually, the design outcomes. In our previous research, we developed three categories of framings for design problem statements based on Kirton’s Adaption-Innovation theory: (1) neutral framing, (2) adaptive framing, and (3) innovative framing. The neutral framing is intended to leave designers uninfluenced with respect to their natural ideation processes. The adaptive framing offers additional constraints ...

Expanding Evidence-Based Pedagogy With Design Heuristics, Seda Yilmaz, Shanna R. Daly, Colleen M. Seifert, Richard Gonzalez, Colin M. Gray

Industrial Design Conference Presentations, Posters and Proceedings

Expanding Evidence-based Pedagogy with Design Heuristics Creative thinking during concept generation has been identified as a key source of successful innovations; thus, techniques to support creative conceptual design are imperative in engineering education. However, teaching students to “think in novatively” has been difficult for many educators, often because of a lack of effective instructional methods. While a variety of methods for concept generation have been published, only one method has been systematically derived from observing engineers during design creation and empirically validated in scientific studies:Design Heuristics. In empirical studies, Design Heuristics have been successfully tested in engineering and design ...

Experimental Boss Design And Testing, Joseph P. Mistretta

Undergraduate Honors Theses

Over the years, gaming has developed rapidly from simple pixel-based experiences to fully blown three-dimensional worlds. As developing technologies improve, so does the complexity and flexibility of what can be created. Encounters, along with all aspects of any gaming experience, have evolved along with the technologies that create them. These intense combat instances, often times referred to as “bosses”, represent a chance for the developer to challenge player skill, cooperation, and coordination. In addition to being major challenges, encounters also allow players to feel a sense of progression as they learn and adapt to mechanics incorporated within an encounter’s ...

Exploring The Role Of Large-Scale Immersive Computing Environments In Collaboration Between Engineering And Design Students, Meisha Nicole Rosenberg Jan 2015

Exploring The Role Of Large-Scale Immersive Computing Environments In Collaboration Between Engineering And Design Students, Meisha Nicole Rosenberg

Graduate Theses and Dissertations

In order to solve the engineering challenges of today, multidisciplinary collaboration is essential. Unfortunately there are many obstacles to communication between disciplines, such as incongruent vocabularies and mismatched knowledge bases, which can make collaboration difficult. The silos separating disciplines, created through focused educational curriculum, are also a large barrier. During their education, designers and engineers are encouraged to employ specific methods unique to their discipline to share ideas with their peers. In many cases, however, these methods do not translate between disciplines, making it challenging for two groups to exchange ideas and perspectives effectively. There are, however, some tools that ...


Design Of A High Intensity Turbulent Combustion System, Mohammad Arif Hossain Jan 2015

Design Of A High Intensity Turbulent Combustion System, Mohammad Arif Hossain

Open Access Theses & Dissertations

In order to design next generation gas turbine combustor and rocket engines, a systematic study of flame structure at high intensity turbulent flow is necessary. The fundamental study of turbulent premixed combustion has been a major research concern for decades. The work is focused on the design and development of a high intensity turbulent combustion system which can be operated at compressible (0.3 < M < 0.5), preheated (T0=500K) and premixed conditions in order to investigate the 'Thickened Flame' regime. An air-methane mixture has been used as the fuel for this study. An optically accessible backward-facing step stabilized combustor has been designed for a maximum operating pressure of 6 bar. A grid has been introduced with different blockage ratios (BR = 54%, 61% & 67%) in order to generate turbulence inside the combustor for the experiment. Optical access is provided via quartz windows on three sides of the combustion chamber. Finite Element Analysis (FEA) is done in order to verify the structural integrity of the combustor at rated conditions. In order to increase the inlet temperature of the air, a heating section was designed to use commercially available in-line heaters. Separate cooling subsystems have been designed for chamber cooling and exhaust cooling. The LabVIEW software interface has been selected as the control mechanism for the experimental setup. A 10 kHz Time Resolved Particle Image Velocimetry (TR-PIV) system and a 3 kHz Planer Laser Induced Fluorescence (PLIF) system have been integrated with the system in order to diagnose the flow field and the flame respectively. The primary understanding of the flow field inside the combustor was achieved through the use of Detached Eddy Simulation (DES) by using commercially available software package ANSYS FLUENT. Preliminary validation is done by 10 kHz TR-PIV technique. Both qualitative and quantitative analysis have been done for CFD and experiment. Major flow parameters such as average velocity, fluctuation of velocity, kinetic energy, and turbulent intensity have been calculated for two distinct Reynolds number (Re = 815 & 3500). PIV results are compared with CFD results which show significant agreement with each other.

There are a wide range of applications for three-dimensional (3D) data in archaeology, and a diverse array of methods for collecting and analyzing those data. In this article, free 3D photogrammetry software (Autodesk 123D Catch) is used to document a series of grave markers. The data are subsequently exported to Geomagic Design X to demonstrate and briefly discuss the various potential analyses that might be used to illustrate the effects of preservation treatments and marker degradation through time. Further, one marker is reverse-engineered, illustrating the capacity of 3D modeling to expedite the process of design, should elements warrant replacement. Additional ...


Proactive Conversation, 3d Printing, And An Old Nintendo, Tesha C. Ellis Jan 2015

Proactive Conversation, 3d Printing, And An Old Nintendo, Tesha C. Ellis

Undergraduate Research Posters

Abstract

One hundred years from now, it would be a true historical treat to be able to showcase 20th and 21st century digital entertainment by presenting video game consoles in mint condition for interactive, educational, play. Arguably, it would be more enlightening and informative for future audiences to be able to physically engage with the electronic artifacts instead of simply observing them behind glass. With the use of 3D technology, components of video game systems can be preserved, and then printed as needed for repairs. It will help keep them functional for future researchers, educators, and enthusiasts.
