Techniques empirically tested with design problems
Techniques Empirically Tested with Design Problems

  • Brainstorming(Lewis, Sadosky, and Connolly, 1975)

  • Brainwriting, Brainstorming, and others(Gryskiewicz, 1988)

  • 6-3-5, C-Sketch, Gallery Method(Shah et al., 1998-2001)

  • Brainsketching, Brainstorming(Van der Lugt, 2002)

  • Variants of Brainstorming that included sketching, and physical models(Vidal, Mulet, and Gómez-Senent, 2004)



Experiment 2 x 3 factorial
Experiment: 2 X 3 Factorial

  • Factor 1: How ideas are exchanged and displayed

    • Rotational Viewing

    • All view simultaneous via gallery style

  • Factor 2: Forms of Communication

    • Written words only

    • Sketches only

    • A combination of words and sketches



Experimental set up
Experimental Set-Up Technique

  • Teams of 5 senior ME students

    • A total of 12 teams

  • Prescribed form of communication and how ideas are displayed

  • 1st Time Period: 10 minutes

    • individuals silently generate ideas

  • Time Periods 2-5:

    • ideas are exchanged and 7 minutes are spent generating ideas

  • Short survey

  • A strong dislike of being restricted to either words or sketches only


Analogical research questions
Analogical Research Questions Technique

  • What forms of analogical representation are most useful for innovative design?

  • What are the fundamental and underlying principles that make analogies useful to a designer?

  • What benefits are there to physical models in design-by-analogy? What types of problems do they highlight? What limitations do they add?

  • What are the effects of different manipulative media in the idea generation process? Which ones lead to design fixation, and which ones are most beneficial for concept development?

Motivation
Motivation Technique

  • Concept generation has a significant impact on product cost and ultimately product success

  • Relying on design teams experience can lead to exclusion of vast number of feasible concepts

  • Analogies between concepts or products can be identified by appropriate (functional) representations

  • Systematic Design by Analogy methodology will enable designers to identify non-obvious solutions leading to innovative designs


Design by analogy state of the art
Design by Analogy State-of-the-Art Technique

  • Analogy is a mapping of knowledge from one domain to another supported by abstract representations

  • Few structured approaches exist to find analogies

  • One approach uses biomimetic principles to search biology text books (Hacco & Shu, 2002)

  • Second approach uses functional modeling and comparison of functional similarity to identify analogies (McAdams & Wood, 2000)




Implications golden nuggets
Implications, Golden Nuggets, … Technique

  • Maximum ideas: rotational viewing w/ words & sketches

    • (hybrid 6-3-5/C-Sketch method)

  • Rotational Viewing produces more ideas than Gallery Viewing.

  • Both individual and group work are important in the idea generation process.

  • As ideas are added the concept’s overall completeness and quality improves.


Implications golden nuggets1
Implications, Golden Nuggets, … Technique

  • Representation matters in design-by-analogy

  • Derivation of design principles through empirical studies is the abstraction process of analogical representation

  • Representation studies and further experiments move us toward a Analogical (“Google”) Search Engine…
