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

Answer: To test functionality, to evaluate the design concept, and to identify potential improvements.

Question 2: Describe the main differences between a mock-up and a working prototype.

Answer: A mock-up is a visual or physical model used for presentation or evaluation, often non-functional, while a working prototype is a functional version used to test how the product performs.

Question 3: Explain why it is important to evaluate a prototype before final production.

Answer: Evaluation helps identify design flaws, ensures the product meets user needs, and allows for improvements to be made before mass production.

Question 4: Sketch a simple plan for a prototype of a new ergonomic handle for a kitchen utensil. Label three features that improve comfort.

Answer: A clear sketch showing the handle's shape, with labels pointing to features such as a contoured grip, soft material insert, and a textured surface for grip.

Question 5: Draw a step-by-step diagram of how you would assemble a basic prototype of a paper-based storage box. Leave space for your diagram.

Answer: A detailed sequence showing cutting the paper/cardboard, folding along scored lines, gluing or taping the edges, and final assembly to form the box.

Question 6: Design a basic prototype of a solar-powered garden light. Describe the materials you would use and the steps to construct it.

Answer: Materials: small solar panel, LED light, battery, plastic casing, wires. Steps: attach solar panel to the top of the casing, connect wires to the LED and battery, secure components inside the casing, and ensure the solar panel faces the sun.

Question 7: Identify three materials suitable for creating a durable, weather-resistant prototype of an outdoor chair.

Answer: Plastic, treated wood, or metal (such as stainless steel).

Question 8: Explain how user feedback can influence the development of a prototype.

Answer: User feedback reveals practical issues and preferences, guiding modifications to improve comfort, usability, or aesthetics.

Question 9: Sketch a design for a prototype of a new type of reusable water bottle. Include features that address environmental concerns.

Answer: A sketch showing a reusable bottle with a lightweight, recyclable material, a wide opening for cleaning, and a leak-proof cap.

Question 10: Describe the key considerations when choosing materials for a prototype intended to be lightweight but strong.

Answer: Materials should have high strength-to-weight ratio, be durable, and suitable for the prototype’s environment, such as carbon fiber or certain plastics.

Question 11: Propose a plan for testing the durability of a prototype shoe sole. Include at least two types of tests you would carry out.

Answer: Abrasion testing by rubbing the sole against rough surfaces, and load testing by applying weight to assess resistance to pressure and wear.
