Final answer:
Function in design refers to how a space or object functions or works, in accordance with the principle that 'form follows function'. This principle ensures that the design is primarily based upon the intended use of the space or object.
Step-by-step explanation:
In the context of designing a well-designed space, Function refers to how it works. The principle that 'form follows function' highlights the importance of a space or object being designed based on its intended utility. This can be seen in architecture, where the design of a building or structure is primarily based upon its intended use, be it for housing, storage, worship, or education. For instance, a warehouse is designed as a large rectangle or square to efficiently store products, while a home has designated areas for cooking, resting, and socializing, tailored to the needs of domestic life. Similarly, in product design, the concept of 'form follows function' suggests that the shape of a product should primarily relate to its intended function, with aesthetic elements coming afterwards to reflect modern tastes and cultural significance.
