Question 1: Define what a design specification is and explain why it is important in the product development process.

Answer: A design specification is a detailed document that outlines the criteria, features, and constraints for a product. It is important because it guides the design process, ensuring the final product meets user needs and manufacturing requirements.

Question 2: Identify three key features that should be included in a specification for designing a new backpack for secondary school students.

Answer: Durability of materials, ergonomic straps for comfort, sufficient storage compartments.

Question 3: List five factors you need to consider when setting specifications for a lightweight, portable camping stove.

Answer: Weight of the stove, heat output, safety features, fuel type compatibility, size and portability.

Question 4: Describe how you would determine the appropriate size and dimensions for a new ergonomic computer mouse.

Answer: By researching average hand measurements, considering user comfort, sketching different sizes, and testing prototypes with users for feedback.

Question 5: Sketch a simple plan for a compact, foldable bicycle lock. Include labels for key features such as the locking mechanism and folding components.

Answer: A clear sketch showing a compact lock with a foldable or collapsible frame, a key or combination lock, and labels indicating the locking mechanism, body, and folding joints.

Answer: A sketch illustrating a handle with a contoured shape that fits the natural grip of the hand, textured surface for grip, and possibly a soft material overlay for comfort.

Question 8: Explain how setting precise specifications can help in the manufacturing process and ensure quality control.

Answer: Precise specifications provide clear standards for dimensions, materials, and functions, making it easier to produce consistent products and identify defects during quality control.

Question 9: Identify two environmental considerations that should be included in the specifications for designing a new eco-friendly product.

Answer: Use of sustainable materials, and designing for easy recycling or disposal.

Question 10: Describe a process you would use to gather user feedback on a prototype before finalising your product specifications.

Answer: Conduct user testing sessions, observe how users interact with the prototype, gather their comments and suggestions, and record any issues or improvements needed.
