Industrial design is the process of designing mass-produced products. It involves creating and executing design solutions for problems related to form, usability, ergonomics, marketing, and more. Industrial design emerged with the Industrial Revolution as manufacturing processes changed and more products needed to be designed. Industrial designers use design methodologies like user research, sketching, and prototyping in their creative process. Some iconic industrial designers include Alvar Aalto, Raymond Loewy, and Dieter Rams, known for products and principles of good design.
