Fittingsuch

Fittingsuch is a term used in systems engineering and design to describe the process of identifying and validating suitable connectors and interfaces between subsystems. It covers mechanical, hydraulic, pneumatic, electrical, and thermal interfaces, with emphasis on compatibility of dimensions, materials, seals, pressure or current ratings, and environmental conditions. The method focuses on early problem framing, constraint gathering, and iterative verification through simulation and testing.

Origin and usage of the term appear mainly in engineering education and design-thinking literature as a concise label for the coupling problem. It is presented as a pedagogical shorthand to illustrate how design teams search for matching components under multiple constraints. Fittingsuch is not a formal industry standard and is not widely used in professional specifications outside classroom or anecdotal contexts.

Method and workflow commonly associated with Fittingsuch begin with requirement capture, identification of candidate fittings, and checks for dimensional and material compatibility, seal types, torque or fastening requirements, and tolerance stack-up. When multiple candidates pass these checks, a prototype assembly is tested for leak-tightness, electrical isolation, signal integrity, or other relevant performance criteria.

Relationship to formal standards is a key consideration. In real-world practice, engineers rely on established standards (such as ISO, DIN, ASME, or IEC) for fittings and connectors. Fittingsuch is typically used as a conceptual framework to guide the selection process and to illustrate design reasoning rather than to replace formal standards.
