Question 1
SL & HLPaper 1
Rapid prototyping is most useful when designers need to:
Question 2
SL & HLPaper 1
What purpose of prototyping is demonstrated in this scenario?
Question 3
SL & HLPaper 2
A company is designing a flat-pack wooden chair intended for mass production and easy home assembly. To support this development, the design team uses a range of modelling techniques to communicate ideas and evaluate the product’s performance.
1.[1]
Figure 1 shows an exploded isometric drawing of the chair, indicating the flat panels, fasteners, and joining mechanisms.
Identify the type of drawing shown in Figure 1.
2.[2]
Figure 2 presents the results of a finite element analysis (FEA) simulation of the chair’s seat under a 100 kg load.
Outline two reasons why a designer would use FEA in the development of this product.
3.[2]
Figure 3 shows a photo of a physical prototype of the chair being tested by a user
Describe two benefits of using a physical prototype to gather user feedback during development.
4.[3]
Explain how computer-aided design (CAD) models can reduce both design time and cost in the production of the chair.
5.[4]
Discuss two advantages and two limitations of using 3D printed rapid prototypes for evaluating the chair’s joint components.
6.[6]
Evaluate how the use of exploded drawings, CAD, and physical prototypes helps the design team communicate effectively with stakeholders throughout the development of the chair.
