Question 1: Read the following design brief: You need to create a reusable water bottle that keeps drinks cold for at least 8 hours and is easy to carry. List three key features your product should have to meet this brief.

Answer: 1. Insulated walls to maintain temperature. 2. A secure, leak-proof lid. 3. An ergonomic, easy-to-hold shape.

Question 2: Identify two materials that could be suitable for making the water bottle described in the brief and explain why they are appropriate.

Answer: Stainless steel because it provides good insulation and durability; BPA-free plastic because it is lightweight and inexpensive.

Question 3: Sketch a simple side view of a design concept for the water bottle. Label the main parts such as the lid, body, and base.

Answer: A sketch showing a cylindrical bottle with a screw-top lid, a smooth body for easy grip, and a stable base. Labels include 'Lid', 'Body', 'Base'.

Question 4: Draw a rough plan view (top view) of the water bottle's lid design, including features that prevent leaks.

Answer: A circular lid with a sealing gasket or silicone ring inside, a screw thread to attach securely, and possibly a small vent hole to prevent pressure build-up.

Question 5: Think about the user experience. What ergonomic feature could you add to make the bottle easier to hold? Describe your idea and sketch how it would look.

Answer: A textured grip area with indents or a rubber coating around the middle of the bottle to prevent slipping. The sketch should show the textured area clearly.

Question 6: Propose a way to make your water bottle more environmentally friendly. Describe your idea and suggest a sustainable material or feature.

Answer: Use biodegradable or recycled plastics for the body, or design the bottle to be easily recyclable. Alternatively, include a feature for refilling to reduce waste.

Question 7: Identify a potential problem with the current design concept and suggest a solution to improve it.

Answer: Problem: The bottle may be too heavy when filled. Solution: Use a lightweight yet insulating material to reduce weight without compromising insulation.

Question 8: Create a simple labelled diagram of a possible carrying case for the water bottle, showing how it protects the product during transport.

Answer: A rectangular case with padding inside, a handle on top, and a secure latch. Labels include 'Padding', 'Handle', 'Latch'.

Question 9: Design a quick-access feature that allows users to add ice cubes easily without removing the entire lid. Describe your idea and sketch the mechanism.

Answer: A small, removable infuser or a side-opening compartment integrated into the lid that can be opened to insert ice. The sketch should show the compartment and how it attaches.

Question 10: Reflect on safety considerations. What features would you include to ensure the product is safe to use? List at least two features.

Answer: 1. A non-slip base to prevent tipping. 2. A secure, child-proof lid to prevent accidental spills.
