Question 1: Define the term 'product specifications' and explain why they are important in the design process.

Answer: Product specifications are detailed descriptions of the features, dimensions, materials, and functions a product must have. They are important because they guide the design process, ensure the product meets user needs, and set clear criteria for manufacturing.

Question 2: Imagine you are designing a water bottle for school use. List at least five key specifications that your product must meet.

Answer: Possible specifications include: a capacity of 500ml, made from BPA-free plastic, a leak-proof lid, a non-slip grip, and a lightweight design suitable for carrying in a bag.

Question 3: Describe how user needs influence the specifications of a product. Provide an example related to designing a portable charger.

Answer: User needs determine the features and constraints of a product. For a portable charger, needs such as compact size, fast charging capability, and compatibility with multiple devices influence the specifications to ensure usability and convenience.

Question 4: Sketch a concept design for a foldable shopping trolley. Include labels for key features such as wheels, handle, and storage compartment.

Answer: A correct sketch would show a trolley with two wheels at the base, an extendable handle, a foldable frame, and a large storage bag. Labels should clearly identify each feature, and the design should suggest ease of folding and portability.

Question 5: Create a list of three environmental specifications that should be considered when designing a reusable coffee cup.

Answer: Durability of materials, thermal insulation properties, and recyclability or eco-friendliness of materials.

Question 6: Design Brief: You are tasked with creating a new desk lamp suitable for students studying late at night. Write a short description of the problem and list three specifications your lamp must have to solve it.

Answer: Problem: Students need a reliable, adjustable light source for late-night studying. Specifications: adjustable brightness levels, energy-efficient LED light, and a flexible arm for directing light where needed.

Question 7: Draw a simple plan of a product that includes a handle, a main body, and a power source (e.g., a small appliance). Label each part clearly.

Answer: A correct plan would show a rectangular main body with a handle attached at the top or side, and an indication of where the power source (such as a plug or battery compartment) is located. Labels should clearly identify each part.

Question 8: Explain the importance of considering safety specifications in product design. Give an example related to designing a children's toy.

Answer: Safety specifications ensure the product does not pose risks to users, especially vulnerable groups like children. For a children's toy, safety considerations include non-toxic materials, no small parts that could be swallowed, and smooth edges to prevent injury.

Question 9: Identify three technical specifications that might be relevant for designing an electric bicycle.

Answer: Motor power (e.g., 250W), battery capacity (e.g., 36V 10Ah), maximum speed (e.g., 25 km/h).

Question 10: Sketch a new ergonomic handle for a kitchen knife. Include features that improve comfort and grip.

Answer: A correct sketch would show a handle with a contoured shape that fits comfortably in the hand, textured or rubberized grip areas, and a sturdy attachment to the blade. Labels should highlight ergonomic features such as contouring and material choice.
