3D Product Product Design Principles 1

Question 1

What does 'Design for Manufacturability' (DFM) mean?

Accepted Answer

Designing products to be easily and cost-effectively produced using available manufacturing processes

Answer

DFM involves simplifying designs, reducing part count, and aligning geometry with manufacturing process constraints to minimize production cost and complexity.

Question 2

What is 'ergonomics' in product design?

Accepted Answer

The science of designing products to fit the human body and optimize comfort, safety, and efficiency

Answer

Ergonomics (or human factors) applies knowledge of human physiology and psychology to design products that minimize fatigue, discomfort, and injury risk for users.

Question 3

What is a 'form factor' in product design?

Accepted Answer

The physical size, shape, and configuration of a product that determines how users interact with and perceive it

Answer

Form factor defines a product's overall shape, dimensions, and physical arrangement — it directly impacts usability, portability, and visual identity.

Question 4

What is 'Design Thinking' as applied to product development?

Accepted Answer

A human-centered innovation methodology using empathize, define, ideate, prototype, and test stages

Answer

Design Thinking is an iterative, empathy-first problem-solving process that deeply understands user needs before generating and testing solutions.

Question 5

What is a 'proof of concept' prototype in product development?

Accepted Answer

A rough, early prototype that demonstrates a core function or technology is feasible, not a finished product

Answer

A proof of concept (POC) prototype validates that a core idea or technology works — it prioritizes function over appearance and is made quickly with available materials.
