Question

Outline three reasons why an engineer would choose to use a prototype as his or her model on a design project.

Answer 1

The correct answer should include that prototypes are how all engineers test the function of their designs, enabling them to make necessary changes to a design before manufacturing the final product. The purpose of the prototype is form and function, so cost-effective material may be used. The prototype can test real-world parameters for simulation and safety and for aesthetics which help in selling an idea to a client.

Answer 2

1. Cost and time effective

Reason: To avoid unnecessary expenses, prototypes are utilised to have a quick estimation on the materials to be used and the associated cost. In this way, designers can properly analyse the functions and overall quality of the product.

2. Get feedback quickly and resolve early product issues

Reason: Whether you have customers or stakeholders, feedback will be vital to your project’s success. The sooner you can provide them with the prototype, the quicker the feedback you can acquire and the process can be shortened.

3. Build better product through many iterations

Reason: The more chances you get to improve the product’s features and functionality using the prototypes, the final product will definitely be better.
