Brainstorming Technique
Founder: Alex F. Osborn (advertising)
4 basic rules: Suspend judgment
Create freewheeling, the wilder the better Quantity is wanted
Combination and improvement are sought
Variant: solo brainstorming, silent brainstorming

Definition
ANALOGY:
Creative stimulation of finding a solution
by mimic the solution of (another) wellknown or well defined case.
(Techniques of Structured Problem Solving, Van Nostrand)

Steps:
1. Identify problem
2. Find a good analogy and select themost interesting
3. Describe the selected reference4. Take the analogy to the problem to
be solved
5. Implement the result

DESIGN PROCESS
DESIGN REQUIREMENTS & OBJECTIVES (DR&O)
Able to chop king grass with equal length
(approximately 3 cm). Able to throw grass far enough after cutting
to avoid clogging Simple, low cost, durable, safe to operate,
and environmentally friendly
Chopping capacity 800 kg/h (enough for20 adult cow).
Portable, easy to move from farm to field

Procedure:
A group of 4-8 people
Define the problem Each participant draws one or more sketches
Pass sketch to others, drawing time 5 Participants develop or annotate sketches, or
use to stimulate new ones
After saturation, collect sketches
Display all sketches, discuss, categorize,
evaluate, and select the solution

Conclusion
First step to innovation: preparation,
incubation, illumination, verification,execution
Once the idea is formed, need a strong
technical basic to transform the idea into
reality
