Models in the Design Process Flashcards
Generate and Explore Ideas
Quick to produce.
Cheap, abundant materials.
Low detail.
Supplement sketches.
Test and Refine Designs
Test ergonomics.
Check moving parts.
Ensure good fit.
Iterative process, many models may be made.
Communicate Designs
Final appearance/function.
Accurate, high-quality finish.
For manufacturers, customers and marketing.
Types of models
Sketch models.
Block models.
Scale models.
Test model.
Prototypes.
Computer generated models.
Sketch Model
Produced quickly from cheap materials to visualise ideas.
Usefulness:
Check scale and size.
Check anthropometrics.
Check functional issues.
Check moving parts and mechanisms.
Check aesthetic factors.
Block Model
Solid model concerned with ergonomics and aesthetics.
Usefulness:
Communicate form and shape.
Test ergonomics.
Present to a client.
Analyse the aesthetics of a design.
Surface details.
Position of buttons.
Scale Model
An enlarged or miniature model with accurate sizes.
Usefulness:
Gather information about sizes.
Check proportion.
Test ergonomics.
Find out assembly methods.
Use for marketing.
Test Model
A model for functional and performance testing.
Usefulness:
Test how well a product works.
Test efficiency.
Test structural suitability.
Test material choice.
Health and safety regulations.
Allow for changes before manufacture.
Prototype
A model for functional and performance testing.
Usefulness:
Prove the viability of a design.
Test a fully working product.
Assist with marketing.
Check for flaws before production.
Computer Generated Models
Fully digital 3D model from CAD/CAM software.
Usefulness:
Can be integrated with CAD system.
Can run simulations.
Check aesthetics with a render.
Used for marketing and promotion.
Check dimensions.
Check assembly methods.
Rapid Prototyping - Benefits
Fast so products are quicker to market.
Save on R&D costs = more profits.
Model is very accurate.
Model is final material for testing.
Able to make changes to the design quickly.
Reduced outsourcing to specialist model makers.
Rapid Prototyping - Drawbacks
Requires expensive equipment and setup costs.
Staff must be trained in its use.
Limited material types available.
Specialist materials can be expensive.
Limited accuracy.
