Exploring Two Phases of Design-by-Analogy "Multiple Solutions" and "Multiple Analogies"

Exploring Two Phases of Design-by-Analogy “Multiple Solutions” and “Multiple Analogies.” (August 2010) Apeksha Gadwal, B.Tech., Jawaharlal Nehru Technological University, Hyderabad, India Chair of Advisory Committee: Dr. Julie Linsey Idea generation and design-by-analogy are core parts of design. Designers need tools to assist them in developing creative and innovative ideas. Analogy is one such tool that helps designers solve design problems. It is a stimulus that helps generate innovative solutions to a design problem. It is used to generate novel ideas by transferring information (i.e. mapping elements) from a known domain (base) to an unknown domain (target). Multiple solutions can be developed based on a single analog and designers derive principles of design from the analogs (products) they experience. There is little research that discusses creating multiple solutions from a single analog or how multiple analogs can assist designers in mapping high level principles of design. Multiple paths are available to improve the design-by-analogy process and help designers understand the process better. This thesis explores two phases of design-byanalogy in which designers have difficulty generating multiple inferences from a single source analog and identifying high level principles given multiple example analogs in the presence of noise. Two hypotheses are proposed to explore the importance of analogies in design. 1. A lone designer is able to generate multiple inferences from a
