Question 1: Define what a prototype is in the context of design and explain its purpose.

Answer: A prototype is an early sample or model of a product used to test and refine ideas. Its purpose is to evaluate design features, functionality, and usability before final production.

Question 2: Describe two different types of prototypes that could be used in the development of a new product.

Answer: Physical prototypes, which are tangible models made from materials to test form and function, and virtual prototypes, which are computer-generated models used for visualisation and simulation.

Question 3: Explain why it is important to test a prototype and list two key aspects that should be evaluated during testing.

Answer: Testing a prototype is important to identify design flaws and improve the product. Key aspects to evaluate include functionality and user comfort or ergonomics.

Question 4: Design a simple sketch of a prototype for a new ergonomic kitchen utensil handle. Label the key features that would improve grip and comfort.

Answer: A correct sketch would show a handle with an ergonomic shape, possibly with textured or rubberised areas for grip, and contours that fit comfortably in the hand. Labels should indicate 'ergonomic shape,' 'textured grip area,' and 'contoured design.'

Question 5: Outline the steps involved in creating a physical prototype from a digital design plan.

Answer: First, develop a detailed digital model using CAD software. Next, select suitable materials and use appropriate manufacturing techniques such as 3D printing or handcrafting to produce the prototype. Finally, evaluate and refine the prototype based on testing.

Question 6: Sketch a plan for a simple prototype of a packaging box intended to protect fragile items during shipping. Include views and key features.

Answer: A plan should include a top view showing dimensions, a side view illustrating the thickness and reinforcement features, and labels indicating padding areas, fold lines, and closure mechanisms.

Question 7: Create a labelled diagram of a basic circuit used in a prototype electronic device, including a power source, switch, and output component.

Answer: The diagram should show a battery (power source) connected to a switch, which when closed completes the circuit to an output device such as a light bulb or motor. Labels should identify each component clearly.

Question 8: Identify two common materials used for creating prototypes and discuss their advantages.

Answer: Foam board, which is lightweight and easy to cut, and cardboard, which is inexpensive and readily available. Both materials are suitable for quick, low-cost prototyping.

Question 9: Explain how feedback from testing a prototype can influence the next stage of the design process.

Answer: Feedback highlights areas for improvement, such as functionality, usability, or aesthetics. This information guides modifications and refinements to develop a more effective final product.

Question 10: Sketch a concept for a foldable mobile phone stand. Include key features that make it functional and portable.

Answer: A correct sketch would show a foldable base with adjustable angles, a support arm, and a slot for holding a phone. Labels might include 'foldable joints,' 'adjustable tilt,' and 'compact design.'

Question 11: Describe the key considerations when choosing materials for a prototype that will be tested for durability.

Answer: Materials should simulate the final product’s properties, be strong enough to withstand handling, and be easy to work with. Cost and availability are also important factors.
