Find Useful Information FAST! 1. Identify information being sought General/specific in narrow/broad field 2. Identify kinds of publications Remember quantity of knowledge < number of documents 3. Start with a standard approach Library and Web-Based Search Engines 4. Evaluate Continuously Deadlines, retrieval delays, minimize sources, seek expert advice, skim read 5. Keep References Accurate and complete 6. Keep Small Collections Only keep what is of foreseeable use
1. Consult In/Experienced Users 2. Define User Interactions Tasks, user abilities, interface 3. Observe In/Experienced Users 4. Record Limiting Values Range of motion, forces, deflections

Example Problem Statement Elimination of puddles on sidewalks Crazy Idea Wait for puddles to evaporate Evaporate Vanish, fade, sink, fly away, die away, melt away dissolve, disappear, etc. Solutions Sink: perforate the paving or corrugate it Fly away: suck the rain off with a cleaning vehicle Dissolve: use porous paving
Write and Re-word Example Welding distortion will cause a gap between adjacent surfaces. Manufacturing tolerances will cause misalignment between two planes. Manufacturing tolerances twoplane misalignment
Intended to force divergent thinking 1. Define functions that any acceptable design must be able to perform Functions to be independent of one another 2. List sub-solutions to perform each function 3. Select acceptable set of sub-solutions One sub-solution for each function

Driven by function, appearance, and economic manufacture Cross-discipline interactions (e.g. engineering, marketing, manufacturing) Human involvement Communication, personality differences, personal ambitions Strong Personalities Insist on their design being superior & not accept others
Basic Idea A group of people thinking and discussing the design in a relaxed and informal manner with even way-out ideas being discussed seriously and positively.
Aim – stimulate a group of people to produce many ideas quickly Rules Criticism is ruled out – judgment withheld until later “Free-wheeling” is welcome – the wilder ideas the better as it is easier to tame down than to think up! Quantity is wanted – the greater the number of ideas, the more likelihood of useful ideas Combination & improvement are sought – seek ways of improving the ideas of others
When doing a brainstorm Optimum number of participants is ~12 Session should be preceded by individual work Allows sufficient time for ideas to incubate Held in an informal, comfortable atmosphere Duration between minutes Approximate 100 ideas should be gathered in this time Leader should keep session going at brisk pace
A theory/system Based on creative thinking Free use of Metaphor Analogy Carefully selected small group Individuals Diverse personality and areas of specialization
Form a Group Flexibility in thinking Range of knowledge and experience Contrasting personalities Group Practice – relating spontaneous activity of brain and nervous system to the problem Direct Analogies Personal Analogies Symbolic Analogies Fantasy Analogies
object by listing its basic characteristics emotions the object might have in a given situation how someone feels when using the object what it feels like to be the object Clear Fruity Happy at dinner Friendly at parties Sophisticated Tired Wanted Important Describe:
Oxymoronic in design Two-word phrase self-contradictory: Careful Haste Related to a particular problem and simulate ideas How might “careful haste” be used to generate ideas for safe evacuation from a school?
How can car breaks adjust themselves? How can we get floors to clean themselves? IOWF – “In our wildest fantasies, how do we get X to do Y?
Permits “spontaneous thinking” to influence “planned thinking”
1. Start in a good direction 2. Record spontaneous thoughts 3. Review planned strategy & spontaneous thoughts 4. Decide to follow planned or ‘switch’ 5. Repeat until spontaneous supports planned
Designer’s Attention Spontaneous thoughts not directly relevant to current approach 1 ST Review – No pattern 2 ND Review – Switch to fit 3 RD Review – Convergence
