Design - Modelling

Question 1

What materials are often used for modelling?

Answer 1

• Cardboard
• Bolsa Wood
• Polystyrene Foam

Question 2

What is the purpose of taking photos of your models?

Answer 2

To keep a record of progress throughout your project

Question 3

What are the benefits of using a model?

Answer 3

• Shows finer details of design

- Point out any designer flaws

Question 4

What is the difference between prototypes and models?

Answer 4

Models:
- Not always functional
- Any Scale
- Usually more for aesthetic demonstration
- Cheap
Prototype:
- Fully functional
- Actual version of intended 
- Expensive
- Often used a demonstrator to possible distributors.

Question 5

What are the main reasons designers use modelling?

Answer 5

Helps with evaluation of prototypes;

• match design specification
• Properly functional
• Experiment tolerances (best/maximum shape for use)

Question 6

What are the 4 types of production?

Answer 6

• Mass - large quantity
• Batch - medium quantity
• One Of - only one
• Continuous - always created

Question 7

What are the two main types of production?

Answer 7

Just In Time (JIT)

Flexible Manufacturing Systems

Question 8

What is the JIT process?

Answer 8

• Product manufacturing responds to customers demand
• New Materials are only ordered when required to reduce the need for storage
• Better for the environment, less goes to landfill
• Miss out on bulk offers
• Must be reliable or delays may occur

Question 9

What is Flexible manufacturing?

Answer 9

• Often used in batch production
• Systems can be easily adapted for newer trends
• Can be expensive due to additional start-up costs

Question 10

Why is one of production more expensive?

Answer 10

The design is usually tailored to a specific person and therefore made by hand of a skilled craftsperson

Question 11

Tools for modelling?

Answer 11

Paper cutter used to cut card.
Roller cutter and arcs in paper can be cut by hand.
Compass cutter can cut in a circle.
Paints for adding colour
Hot wire stripper for foam.

Question 12

The use of computers in modeling

Answer 12

Apply colour and texture in seconds
Potential customers can give easy feedback
Spreadsheets calculate costs
Computer software create easy designs

Question 13

The use of realistic based models?

Answer 13

See the physical 3D form
Help to spot faults
Experiment with materials
Passed around easier to show how product will look.
