What is the function of a concept board in product design?

A concept board serves primarily to display ideas and design elements for review, making it an essential tool in the early stages of product design. By visually presenting concepts, materials, colors, shapes, and layout options, it allows designers to communicate their visions effectively to stakeholders, clients, or team members. This collaborative evaluation fosters discussion and feedback, which can lead to refined ideas and better decision-making as the design process progresses.

The other choices do not align with the primary purpose of a concept board. Finalizing technical specifications is typically a more advanced stage of product development and not where initial ideas are presented. Securing intellectual property relates to legal protection, which is distinct from the conceptual and visual brainstorming phase. Assessing color preferences is just a small aspect of what a concept board can achieve, as it encompasses a broader range of visual elements and ideas.
