3D Product Product Design Principles 2

Question 1

What is a 'design brief' in the product development process?

Accepted Answer

A document defining the product's goals, target user, constraints, and success criteria before design begins

Answer

A design brief captures the problem to be solved, user needs, design constraints, business goals, and evaluation criteria — it guides all subsequent design decisions.

Question 2

What is 'anthropometry' and how is it applied in product design?

Accepted Answer

The study of human body dimensions and proportions, used to size products for target user populations

Answer

Anthropometry provides statistical data on human body dimensions (hand size, reach, grip diameter) used to determine appropriate product dimensions for a target demographic.

Question 3

What does 'Design for Assembly' (DFA) aim to achieve?

Accepted Answer

Reducing the number of parts and simplifying assembly steps to lower labor time and assembly errors

Answer

DFA analyzes assembly sequences to reduce part count, eliminate fasteners, and simplify joining operations — reducing assembly time and defects.

Question 4

What is a 'CMF' (Color, Material, Finish) specification in product design?

Accepted Answer

A design deliverable that defines the exact colors, materials, and surface finishes for every element of a product

Answer

CMF specifications define every visual and tactile aspect of a product — Pantone colors, material grades, texture standards — ensuring consistent production quality.

Question 5

What is 'Universal Design' in product development?

Accepted Answer

Designing products to be usable by the widest possible range of people regardless of age, ability, or situation

Answer

Universal Design creates inclusive products usable by people with diverse abilities — the seven principles include equitable use, flexibility, and low physical effort.
