Concept design refers to the initial stage of the design process where ideas are generated and explored to define the overall vision of a project. This phase typically involves brainstorming, sketching, and creating prototypes to communicate the core concepts and functionalities of a product, system, or experience. Concept design helps to establish the aesthetic and functional direction before moving on to more detailed development. It’s all about translating ideas into tangible concepts that can be refined and implemented later on.
