Which prototype type shows the right size and shape and dimensions but does not work?

• A. Visual prototype
• B. Proof of concept
• C. Production prototype
• D. Demonstrator prototype

Answer: (A)

When a prototype focuses on appearance and overall form rather than function, it’s testing size, shape, and dimensions to see if the product looks and feels right. A visual prototype is used to check aesthetics, ergonomics, and how the product sits in hand or in its intended environment without making the mechanism work. This helps get feedback on look, proportions, and finish before building functional versions. That’s why it’s the best choice here: it represents the right size and shape but doesn’t require the product to operate. The other types would be used to show that the idea works, demonstrate functionality, or approach real production, rather than simply confirming form.
