Question 1: Identify three key considerations you should include in a design specification for a new reusable water bottle intended for students. Explain why each is important.

Answer: Key considerations include: 1) Material durability - to withstand daily use; 2) Size and capacity - to ensure it fits in bags and holds enough water; 3) Ease of cleaning - to maintain hygiene. Each consideration ensures the product is practical, user-friendly, and safe.

Question 2: Describe a scenario where a product's specifications might need to be adjusted during the development process. Include at least two reasons why adjustments could be necessary.

Answer: If initial testing shows that the product is too heavy or uncomfortable, the specifications for weight or ergonomic features may need adjusting. Reasons include user feedback indicating discomfort or material limitations that prevent the original design from being feasible.

Question 3: Sketch a basic plan for a portable phone holder designed to attach to a bicycle. Include key features like attachment points and protective elements. Use labels to explain your design choices.

Answer: A correct sketch would show a clamp or strap system to attach to handlebars, a cradle or slot to hold the phone securely, and padding or rubber to prevent slipping or damage. Labels should specify attachment mechanism, contact points, and protective features.

Question 4: List at least four specifications for a lightweight folding camping chair aimed at backpackers. For each, state why it is essential.

Answer: Specifications include: 1) Lightweight materials (to reduce overall weight); 2) Compact folding size (for easy packing); 3) Durable frame (to withstand outdoor conditions); 4) Comfortable seat and backrest (for user comfort). Each ensures portability, durability, and comfort.

Question 5: Design a set of criteria for evaluating whether a new office chair meets ergonomic standards. Include at least three criteria and justify their importance.

Answer: Criteria could include: 1) Adjustable height (to suit different users); 2) Lumbar support (to prevent back pain); 3) Seat depth and width (for comfort and proper posture). These ensure the chair promotes good posture and user comfort.

Question 6: Imagine you are designing a new lunchbox for school children. What specific design specifications would you set to ensure the product is appealing and practical? List at least three and explain.

Answer: Specifications include: 1) Bright, attractive colours or patterns (to appeal to children); 2) Secure locking mechanism (to prevent spills); 3) Insulated walls (to keep food fresh). These features make the lunchbox attractive, functional, and suitable for daily use.

Question 7: Sketch a concept for a compact, eco-friendly shopping bag that can be folded into a small pouch. Include labels to highlight key features such as material, folding mechanism, and carrying handles. Describe what a correct sketch should display.

Answer: A correct sketch would show a flat, lightweight bag made from sustainable material, with a foldable or roll-up section to fit into a small pouch. The sketch should include handles, a clear folding line or mechanism, and labels indicating the eco-friendly material and design features.

Question 8: Explain how user feedback can influence the specifications of a new product. Provide an example related to a portable Bluetooth speaker.

Answer: User feedback may reveal that the speaker’s battery life is too short, leading to a revision of the specification to include a larger battery or more efficient power management. Feedback ensures the product meets real user needs and improves satisfaction.

Question 9: List two environmental considerations that should be included in the specifications of a new reusable coffee cup. Justify each consideration.

Answer: Considerations include: 1) Use of biodegradable or recyclable materials (to reduce environmental impact); 2) Minimal packaging during manufacturing (to lower waste). These considerations help make the product more sustainable and environmentally friendly.
