My first instinct was to just describe a handle and call it a day, which would've been a disaster.
Start by clarifying the context and constraints (e.g., target users, vehicle type, environment) to show adaptability. Then walk through a structured design process: define the problem, ideate solutions, prototype, and test, emphasizing user needs and trade-offs. Conclude by reflecting on how you'd measure success and iterate.
Pro tip: Anchor your design in a specific user scenario (e.g., a parent carrying groceries in the rain) to make your solution tangible and demonstrate empathy. Also, proactively discuss trade-offs (cost, manufacturability, accessibility) to show product sense.
Ask questions to understand the context: Who is the user? What type of vehicle? What are the key constraints (budget, materials, safety)? This shows you can navigate ambiguity.
Identify the core jobs-to-be-done: opening/closing the door easily, securely, and comfortably in various conditions (rain, cold, hands full). Consider accessibility and ergonomics.
Brainstorm multiple concepts (e.g., traditional lever, flush handle, sensor-based, biometric). Sketch 2-3 ideas and discuss their pros and cons relative to user needs and constraints.
Describe how you would prototype (low-fidelity mockups, 3D prints) and test with users. Outline key metrics: ease of use, time to open, user satisfaction, durability.
Explain how you'd use feedback to refine the design and define success metrics (e.g., reduced effort, increased accessibility). Discuss potential trade-offs and how you'd prioritize.
