Question 1: Describe three key features you would include in a product designed for elderly users to improve safety and ease of use. Explain why each feature is important.

Answer: Potential features include: 1) Large, easy-to-press buttons to accommodate limited dexterity; 2) Non-slip grips to prevent slipping; 3) Clear, simple instructions or labels for ease of understanding.

Question 2: Imagine a newly designed water bottle that claims to keep beverages cold for longer. List two aspects of the design you would evaluate to verify this claim and explain how you would assess them.

Answer: Evaluate the insulation quality by testing temperature retention over time; assess the sealing mechanism to prevent heat transfer or leaks.

Question 3: Evaluate the ergonomic considerations of a kitchen knife designed for professional chefs. What features would you look for, and how would they enhance usability?

Answer: Features to evaluate include a comfortable, non-slip handle; balanced weight distribution for control; appropriate blade length and sharpness; these features improve comfort, safety, and efficiency during use.

Question 4: Design Brief: A company wants to create a lightweight, foldable bicycle for commuting in urban areas. Develop two criteria you would use to evaluate the final product's suitability for city commuters.

Answer: Criteria could include: 1) Ease of folding and unfolding for quick storage; 2) Overall weight to ensure portability and ease of carrying.

Question 5: Sketch a simple design for a portable phone holder intended for use in cars. Your sketch should include key features that prevent the phone from slipping or falling.

Answer: A correct sketch would show a holder with a supportive base, side grips or clamps, and possibly a textured surface or rubber padding to prevent slipping.

Question 6: Identify two potential weaknesses in a plastic storage container designed for food preservation. Suggest improvements to address these weaknesses.
