Innovative Solutions Through Innovated Problems, Shanna R. Daly, Seda Mckilligan, Jaryn A. Studer, Jaclyn K. Murray, Colleen M. Seifert Jan 2018

Innovative Solutions Through Innovated Problems, Shanna R. Daly, Seda Mckilligan, Jaryn A. Studer, Jaclyn K. Murray, Colleen M. Seifert

Industrial Design Publications

Designers are accustomed to solving problems that are provided to them; in fact, common practice in engineering is to present the problem with carefully delineated and detailed constraints required for a promising solution. As a consequence, engineers focus on creating feasible solutions rather than exploring novel perspectives on the presented problems. However, the Engineer of 2020 needs to respond with innovations for multiple and dynamic user needs, diverse users and cultures, and rapidly changing technologies. These complex demands require engineering students to learn that problems are not ‘‘fixed’’ as presented, and to build the habit of exploring alternative perspectives on ...


Comparison Of Design Approaches Between Engineers And Industrial Designers, Seda Yilmaz, Shanna R. Daly, Colleen Seifert, Rich Gonzalez Sep 2013

Comparison Of Design Approaches Between Engineers And Industrial Designers, Seda Yilmaz, Shanna R. Daly, Colleen Seifert, Rich Gonzalez

Industrial Design Conference Presentations, Posters and Proceedings

Design Heuristics are an idea generation tool based on empirical evidence from successful designs. The heuristics serve as cognitive “shortcuts” that encourage exploration of novel directions during concept generation. Design Heuristics were identified from an analysis of hundreds of innovative products and from studies of expert engineering and industrial designers. The research reported in this paper examines the utility of Design Heuristics instruction in two different classroom settings with engineering and industrial design students. The aim was to test whether design heuristics can play a useful role in creating new designs and overcoming fixations in the design process. Twenty novice ...


An Integrated Approach To Information Modeling For The Sustainable Design Of Products, Douglas C. Eddy, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden, Paul Witherell, Kemper E. Lewis Jan 2013

An Integrated Approach To Information Modeling For The Sustainable Design Of Products, Douglas C. Eddy, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden, Paul Witherell, Kemper E. Lewis

Center for e-Design Proceedings

The design of more sustainable products can be best accomplished in a tradeoff-based design process that methodically handles conflicting objectives. Such conflicts are often seen between, environmental impact, cost, and product performance. To support such a process, we propose the development of an environment where sustainability considerations are explicitly introduced early into the design process. This explicitness is provided by integrating the requirements information of sustainability standards and regulations directly into the design process. The emergence of the semantic web provides an interoperable environment in which the context and meaning of knowledge about the relationships among various domains can be ...


Improved Knowledge Management Through First-Order Logic In Engineering Design Ontologies, Paul Witherell, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden May 2010

Improved Knowledge Management Through First-Order Logic In Engineering Design Ontologies, Paul Witherell, Sundar Krishnamurty, Ian R. Grosse, Jack C. Wileden

Center for e-Design Publications

This paper presents the use of first-order logic to improve upon currently employed engineering design knowledge management techniques. Specifically, this work uses description logic in unison with Horn logic, to not only guide the knowledge acquisition process but also to offer much needed support in decision making during the engineering design process in a distributed environment. The knowledge management methods introduced are highlighted by the ability to identify modeling knowledge inconsistencies through the recognition of model characteristic limitations, such as those imposed by model idealizations. The adopted implementation languages include the Semantic Web Rule Language, which enables Horn-like rules to ...


A Web-Based Environment For Documentation And Sharing Of Engineering Design Knowledge, Justin A. Rockwell, Paul Witherell, Rui Fernandes, Ian R. Grosse, Sundar Krishnamurty, Jack C. Wileden Jan 2008

A Web-Based Environment For Documentation And Sharing Of Engineering Design Knowledge, Justin A. Rockwell, Paul Witherell, Rui Fernandes, Ian R. Grosse, Sundar Krishnamurty, Jack C. Wileden

Center for e-Design Proceedings

This paper presents the foundation for a collaborative Web-based environment for improving communication by formally defining a platform for documentation and sharing of engineering design knowledge throughout the entire design process. In this work an ontological structure is utilized to concisely define a set of individual engineering concepts. This set of modular ontologies link together to create a flexible, yet consistent, product development knowledge-base. The resulting infrastructure uniquely enables the information stored within the knowledge-base to be readily inspectable and computable, thus allowing for design tools that reason on the information to assist designers and automate design processes. A case ...
