Types of Designs

Configuration design.

Parametric design.

Original design

Configuration Design

This deals with the selection and arranging of components to improve performance and reduce size.

Example: location of air planes engines, location of shifting mechanism of a two speed wheel chair.

Parametric Design Deals with varying design parameter to

achieve design objectives.

Boeing used this approach to design aircrafts.

Original Design

This refers to designs that are substantially different than existing designs.

The push button telephone is an example of a sudden major departure from rotary phone.

Characteristic of Creative Thinking

Creative ideas are new combinations of previously unrelated ideas.

Creative ideas are new original ideas solving problems in new and original ways.

A product of unconscious mind.

Elusive ideas.

Models of Creative Thinking

Wallas Model (1926). Preparation : The stage of clarifying and

defining the problem. Incubation: The mind is relaxed free the

conscious. Illumination: Recognition of the new idea

(Eureka) Verification: To check if the idea has

merit.

Fabun Model (1968)

Desire: Shock and need to restore equilibrium.

Preparation: Clarifying and defining the

problem.

Manipulation: manipulate ideas.

Incubation: Same as Wallas model.

Intimation: The feeling you get when you realize

you are on the right track.

Illumination: Same as in wallas.

Verification: Same as Wallas.

Creative Education Foundation Model

Fact finding: Collect facts that may have

bearing on the problem.

Problem finding: Developing alternative

statements of the problem.

Idea finding: Where possible solution are

first presented.

Solution finding: This is the evaluation

phase.

Consolidated Model Exploration : The active and concerted

search of new ideas. Incubation: The extended period of

relaxation during which conscious effort for addressing the problem is made.

Intimation: The resumption of purposeful pursuit combined with the feeling of making progress.

Illumination: The breakthrough that produces an attractive new idea.

Creative Personalities Optimistic

Confident

Enthusiastic

Endorses no perceived solution.

Adventures spirit

Willing to take risk.

Has a good sense of humor

Modes of Thinking

Left brain: Deductive, derivative,

Specific, Logical, Hard and Linear.

Right brain: Inductive, Integrating,

General, Imaginative, Fuzzy and Nonlinear.

Types of Barriers to Creative Thinking

Perceptual

Cultural

Environmental

Emotional

Intellectual

Types of Perceptual Barriers

Patterns

Boundaries

Illusions

Lens

Meaning.

Techniques for Generating Alternatives

Lateral thinking

• Do not pursue a design in detail

• Avoid critiquing any of the concepts.

Perseverance • Try many times

Mental Push -Ups

Making lists.

Word games.

Solving puzzles.

Magic tricks.

Procedural Techniques

Brain storming. Brain writing. Story boarding. Random simulation. Analogies
