Question 1: Read the following scenario: You need to design a reusable water bottle for school students. Identify three important features your water bottle should have to meet students' needs.

Answer: Features could include a leak-proof lid, a capacity suitable for a school day (e.g., 500ml), and a lightweight, durable material.

Question 2: Describe a problem that might occur if a water bottle is made from a fragile material. How could this influence your design specifications?

Answer: If the material is fragile, the bottle could easily break, leading to spillages and waste. Therefore, the specification should include using a strong, impact-resistant material.

Question 3: List at least three specifications that are important for designing a comfortable ergonomic handle for a shopping bag.

Answer: Specifications might include a handle width that fits comfortably in the hand, a non-slip surface, and a strong attachment to carry heavy loads safely.

Question 4: Sketch a simple design for a keyring that attaches to a backpack. Include the main features that make it functional.

Answer: A correct sketch would show a small, sturdy ring with a clip or clasp mechanism, possibly with a space for branding or a decorative element. It should look easy to attach and detach.

Question 5: Draw a plan for a compact, portable pencil case suitable for students. Label key features such as compartments, zippers, and handles.

Answer: A well-drawn plan would include a rectangular shape, multiple compartments for pens and pencils, a zipper closure across the top, and a small handle or grip on the side.

Question 6: Explain why it is important to specify the maximum weight a portable device can have. How does this affect your design?

Answer: Specifying the maximum weight ensures the product remains portable and comfortable to carry. It influences material choice and overall size to reduce weight.

Question 7: Identify two safety considerations that must be included in the specifications for designing a children's night lamp.

Answer: Safety considerations include ensuring the lamp does not overheat and that electrical components are insulated to prevent shocks.

Question 8: Describe how you would test a new design to ensure it meets the specifications for durability and usability.

Answer: Testing could include subjecting the product to repeated use or impact to check durability, and user trials to assess comfort and ease of use.

Question 9: Create a list of five key specifications for designing an eco-friendly lunchbox. Include material choices and features.

Answer: Specifications could include using biodegradable or recycled materials, a leak-proof lid, multiple compartments for different foods, a lightweight design, and easy-to-clean surfaces.
