Question 1: Read the following design brief: 'Design a portable, eco-friendly lunch box suitable for school children.' Identify three key features that your product should include to meet this brief.

Answer: Features could include: 1) Insulated compartment to keep food fresh; 2) Made from sustainable, biodegradable materials; 3) Compact and lightweight design for easy carrying.

Question 2: Based on the same brief, suggest two different materials that could be used to manufacture the lunch box and justify your choices.

Answer: Possible materials include: 1) Recycled plastic for durability and sustainability; 2) Bamboo or biodegradable bioplastics for eco-friendliness and strength.

Question 3: Identify and explain one potential problem with a traditional lunch box that your innovative design aims to solve.

Answer: A traditional lunch box may not be insulated, causing food to spoil or become cold. The new design aims to include insulation to maintain food temperature.

Question 4: Sketch a rough design of your eco-friendly lunch box, indicating key features such as compartments, handles, or closures. Use labels to explain your design choices.

Answer: A clear sketch showing a rectangular lunch box with a secure lid, insulated lining, a carry handle, and compartments inside for different food items. Labels should explain features like 'insulation for temperature control' and 'biodegradable material.'

Question 5: Describe two alternative ways to open and close your lunch box to improve ease of use for children. Include brief explanations of how these work.

Answer: Options include: 1) A push-button latch that releases with a single press; 2) A sliding lock mechanism that is easy to operate with one hand.

Question 6: Propose an innovative feature that could make your lunch box more appealing to children and explain how it enhances the product.

Answer: Adding a built-in compartment for a small ice pack or a fun, customizable outer design can make it more appealing and functional for children.

Question 7: Identify one environmental benefit of using biodegradable materials in your product design.

Answer: Biodegradable materials reduce landfill waste and environmental pollution by breaking down naturally over time.

Question 8: Draw a diagram of a foldable handle for your lunch box. Indicate how it attaches to the main body and explain its mechanism of operation.

Answer: A detailed drawing showing a handle that folds flat against the lid when not in use, with hinges or pivot points for folding. Labels should explain how the handle locks into position for carrying and folds away for compact storage.

Question 9: Suggest one way to test the durability of your lunch box design and describe the testing process.

Answer: Drop the lunch box from a height of 1 meter onto a hard surface multiple times to assess its impact resistance, checking for cracks or damage afterward.

Question 10: Identify a potential safety concern with your design and suggest a solution to address it.

Answer: A sharp-edged lid could cause cuts; adding rounded edges or a safety lip can prevent injuries.

Question 11: Summarise how your design idea meets the needs of the target user (children in school).

Answer: The design is lightweight, easy to open and close, made from safe, eco-friendly materials, and includes features appealing to children, such as fun designs or compartments for different foods.
