The Concept Electronics Show

Concept designs (and worse, concept videos) are a sign of dysfunction and incompetence at a company. It’s playing make-believe while fooling yourself and your audience into thinking you’re doing something real. Concepts allow designers to ignore real-world constraints: engineering, pricing, manufacturing, legal regulations, sometimes even physics. But dealing with real-world constraints is the hard work of true design. Concepts don’t stem from a lack of confidence. They stem from a dereliction of the actual duties of design.
