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

Answer: A product specification is a detailed document that outlines the requirements, features, and constraints of a product. It is important because it guides designers and manufacturers to ensure the final product meets user needs and functions correctly.

Question 2: Think of a product you use daily, such as a water bottle. List at least five key specifications that would be important for designing a new water bottle.

Answer: Key specifications might include capacity (e.g., 500ml), material (e.g., BPA-free plastic), size and shape, insulation properties, durability, and ease of use (e.g., a screw-top lid).

Question 3: Sketch a simple design plan for a portable phone holder. Include the main features and dimensions in your plan.

Answer: A correct sketch would show a basic outline of the holder, with features like a cradle for the phone, support arms, and possibly a base. Dimensions should include the length, width, and height that fit typical phone sizes, e.g., 15cm x 8cm x 10cm.

Question 4: Create a list of three possible user needs for a new school pencil case.

Answer: User needs could include: enough space to hold multiple pens and pencils, a durable material to withstand daily use, and a secure zipper to prevent items from falling out.

Question 5: Design a product brief for a reusable shopping bag aimed at reducing plastic waste. Include key features and target user needs.

Answer: The brief should specify features such as large capacity, foldability, strong handles, and eco-friendly materials. User needs include durability, ease of carrying, and environmental benefits.

Question 6: Draw a concept sketch for a compact, ergonomic kitchen tool designed for peeling vegetables. Label the main parts and indicate how it improves comfort or efficiency.

Answer: A correct sketch would depict a hand-held tool with a comfortable handle, a peeling blade or surface, and possibly a finger guard. Labels might include handle, peeling surface, and grip area. The design should suggest ease of use and ergonomic comfort.

Question 7: Identify three constraints that a designer must consider when creating a new sports water bottle.

Answer: Constraints include material restrictions (must be BPA-free and safe), size limitations (fits in standard bottle holders), and cost (affordable to manufacture).

Question 8: Propose two different materials that could be used to make a lightweight, durable backpack. Explain why these materials are suitable.

Answer: Materials such as nylon or polyester are suitable because they are lightweight, strong, and resistant to wear and tear. They also dry quickly and are relatively inexpensive.

Question 9: Sketch a plan for a new type of desk organizer that holds pens, paper clips, and sticky notes. Include the layout and key features.

Answer: A correct plan would show a rectangular container with separate compartments for pens, paper clips, and sticky notes. Labels might include 'pen holder,' 'small tray for paper clips,' and 'sticky note pad.' The layout should be practical and space-efficient.

Question 10: Explain how understanding user needs influences the choice of materials and features in a product design.

Answer: Understanding user needs helps designers select appropriate materials that are durable, safe, and comfortable. It also guides the inclusion of features that improve usability, accessibility, and overall functionality, ensuring the product meets the actual needs of users.
