Question 1: Define what a prototype is in the context of product design.

Answer: A prototype is a preliminary model of a product used to test ideas, functions, and design features before creating the final version.

Question 2: Why is prototyping an important stage in the design process? List two reasons.

Answer: Prototyping allows designers to test and evaluate ideas, identify problems early, and make improvements before final production.

Question 3: Describe the main differences between a low-fidelity and a high-fidelity prototype.

Answer: A low-fidelity prototype is a simple, rough version often made with basic materials, used for initial ideas. A high-fidelity prototype closely resembles the final product in appearance and function, used for detailed testing.

Question 4: Imagine you are designing a new chair. Outline three features you would include in your initial prototype.

Answer: Features could include a comfortable seat, sturdy legs, and an ergonomic backrest.

Question 5: Sketch a simple plan for a prototype of a reusable water bottle. Include labels for key features such as the cap, body, and spout.

Answer: A clear sketch showing a cylindrical bottle with a screw-on cap, a spout or drinking hole, and labels indicating each part.

Question 6: Describe three materials that could be used to make a prototype of a mobile phone case and explain why.

Answer: Materials could include foam for quick shaping, plastic for durability, and cardboard for initial fitting. Foam is lightweight, plastic is sturdy, and cardboard is inexpensive for early models.

Question 7: What are some common methods used to create prototypes? List at least three.

Answer: Methods include 3D printing, handcrafting models from cardboard or foam, and using computer-aided design (CAD) for digital prototypes.

Question 8: Sketch a simple prototype of a keyring holder that can be attached to a bag. Show the main shape, a clasp or attachment point, and any additional features.

Answer: A sketch should include a basic shape of the holder, an attachment clip or hole, and possibly a decorative or functional element like a pocket or hook.

Question 9: Explain why testing a prototype is an essential part of the development process. Provide two reasons.

Answer: Testing helps identify flaws and usability issues, and allows for improvements to be made to ensure the final product functions effectively.

Question 10: Imagine you have created a prototype of a new pencil case. List two types of feedback you would seek from potential users.

Answer: Feedback on how easy it is to open and close, and whether it holds enough pens and pencils comfortably.

Question 11: Draw a plan for assembling parts of a simple lamp prototype. Include the base, stand, and light source, with labels for each component.

Answer: A detailed sketch showing the base at the bottom, a vertical stand, and a light source (bulb or LED) at the top, with labels for each part.
