Formuan

Formuan is a term used in speculative design and theoretical modeling to refer to a minimal unit of form within complex systems. It is defined as a configurable element that combines geometry, relations, and behavior in a single entity. The concept is used to discuss modularity and the emergence of structure in artifacts, interfaces, and environments.

A formuan is described by three dimensions: geometry, which covers shape, size, and spatial properties; relations, which encompass connections to other formuans, including adjacency, coupling, and constraints; and behavior, which concerns the functional role and dynamic responses of the unit. A formal profile may include a geometry descriptor, a relation map, and a behavior specification, allowing comparison across contexts.

History and usage of the term are informal and largely theoretical. Formuan has appeared in discussions of modular design and systems thinking within speculative and design-oriented literature, where it serves as an analytic device to discuss how components contribute to the overall structure of a system. It is not tied to a single discipline and is used conceptually in fields such as architecture, software, and product design.

Examples within thought experiments illustrate formuan without asserting a universal standard. For instance, a formuan F1 might be a cube that connects to another formuan F2 via a hinge and exhibits a simple opening behavior. Such examples emphasize the descriptive role of formuan rather than prescribing universal rules.
