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

ANALOGYMETHOD


16/35

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)


17/35

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


18/35

Types of analogy:

1. Close/direct2. Fantasy

3. Remote and/or surprising4. Personal/component

KING GRASS CHOPPER

KINGGRASS CHOPPER

(Brainstorming Example)


20/35

BACK GROUND

Need of machine to chopking grass for dairy cow

Market opportunity to

satisfy breeder demand


21/35

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


22/35

DESIGN PROCESS

Conceptual Design Principle of operation : single operator


23/35

DESIGN PROCESS

Detail Design Cutting blades & toothed roll feeder


24/35

MANUFACTURING

Welding, assembling, finishing

Use jigs & fixtures to ensure alignment

Perform minor modifications duringassembly process to accommodatesimplicity of installation

Put marks on modified parts fordrawing revision

TRIAL of the PROTOTYPE

Observe and

measureperformance

Inspect malfunction

and failures of parts Modify design

BRAIN SKETCHING(Van Gundy, 1988)


27/35

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
