Question 1: Identify three key purposes of creating a prototype in the design process.

Answer: To test the functionality of a design, to gather user feedback, and to identify potential improvements or faults before final production.

Question 2: Describe the main differences between a low-fidelity and a high-fidelity prototype.

Answer: A low-fidelity prototype is simple, often handmade or basic, focusing on basic form and function, while a high-fidelity prototype closely resembles the final product in appearance and functionality, often using similar materials and detailed features.

Question 3: Sketch a basic plan for a prototype of a new ergonomic pen. Include key features that improve comfort.

Answer: A sketch showing a pen with a contoured grip area, textured surface for better hold, and an overall shape that fits comfortably in the hand. The sketch should label the grip area and suggest material or surface texture.

Question 4: Explain why it is important to test a prototype with real users before finalising a product.

Answer: Testing with real users helps identify practical issues, gathers genuine feedback on usability and comfort, and ensures the final product meets the needs and expectations of the target audience.

Question 5: Design a simple prototype plan for a reusable water bottle aimed at children. Include materials and features you would use.

Answer: A plan including a durable, lightweight plastic body, a screw-on lid with a spout, bright colours or fun patterns, and textured grip areas. The plan should specify materials like BPA-free plastic and features like a leak-proof lid.

Question 6: Draw a concept sketch of an adjustable stand for a smartphone. Indicate how it can be altered to different viewing angles.

Answer: A sketch showing a base with a sliding or pivoting support arm, with labels indicating adjustable joints or mechanisms that allow changing the viewing angle.

Question 7: List three qualities that make a prototype effective in the development process.

Answer: Accurate representation of the final product, functionality testing capability, and ease of modification for improvements.

Question 8: Describe the steps you would take to convert a rough prototype into a more refined version.

Answer: Evaluate the initial prototype, gather feedback, identify areas for improvement, make necessary modifications, and create a more detailed or polished version for further testing.

Question 9: Sketch a prototype of a folding picnic table suitable for outdoor use. Include mechanisms that allow it to fold compactly.

Answer: A sketch showing a table with foldable legs, hinge joints, and a tabletop that can be folded in half or collapsed, with labels indicating the folding mechanisms.

Question 10: What materials would you choose for a prototype of a lightweight, durable shopping trolley, and why?

Answer: Materials such as lightweight aluminium or reinforced plastic for frame parts for durability and lightness, and sturdy fabric or plastic for the bag to withstand weight and wear.
