Question 1: Define what a prototype is in the context of product design.

Answer: A prototype is an initial working model of a product that allows designers to test ideas, functions, and usability before final production.

Question 2: Describe two reasons why creating prototypes is important in the design process.

Answer: Prototypes help identify design flaws early, allowing for improvements. They also enable users and stakeholders to give feedback, ensuring the product meets needs.

Question 3: List three materials that could be used to make a simple prototype of a mobile phone case.

Answer: Plastic, foam, cardboard.

Question 4: Design Brief: You have been asked to create a prototype for a new type of ergonomic pencil grip. Outline the key features your prototype should include.

Answer: The prototype should include an ergonomic shape that fits comfortably in the hand, a non-slip surface, and a hole for the pencil to secure it in place.

Question 5: Sketch a basic plan for a prototype of a foldable phone stand. Include labels for key parts and mechanisms.

Answer: A clear sketch showing the base, adjustable support arm, hinge points, and a slot to hold the phone. Labels should include 'Base', 'Support Arm', 'Hinge', and 'Phone Slot'.

Question 6: Draw a cross-section sketch of a simple prototype of a bottle opener. Show the main functional parts.

Answer: A sketch showing the handle, the open-ended metal part that hooks onto the bottle cap, and the area where force is applied. Labels should include 'Handle', 'Hook', and 'Leverage Point'.

Question 7: Explain two advantages of creating a physical prototype instead of just a digital model.

Answer: Physical prototypes allow for hands-on testing and realistic evaluation of size, feel, and function. They can also reveal issues that may not be apparent in digital models.

Question 8: Identify and describe two common problems that might occur during prototyping.

Answer: Materials may not behave as expected, leading to inaccurate results. Additionally, prototypes might be too rough or poorly assembled, making testing unreliable.

Question 9: Design Brief: You are tasked with creating a prototype for an eco-friendly lunchbox. Sketch your initial design idea and label the key features that make it environmentally friendly.

Answer: A sketch of a lunchbox made from recycled materials, with labels such as 'Recycled Plastic', 'Leak-proof Lid', and 'Reusable Design'.

Question 10: Describe what considerations you would make when choosing materials for a prototype intended to test the durability of a new chair design.

Answer: Consider materials that mimic final product durability, such as strong plastics or lightweight metals. The materials should withstand testing stresses without breaking and be safe for handling.
