B.5.RC:5.2 - Recovering a display-stand assembly design

A specification asks for a portable display. It supplies a base, an upright and a panel, together with these rules: the upright can be joined to the base when their fittings match; the panel can be attached to the mounted upright when their fittings match.

Working backward from an assembled display yields a mounted upright and a compatible panel. Recovering the mounted upright yields the base, upright and their fitting condition. Working forward gives the assembly order: join base and upright, then attach the panel.

Inspection of the supplied parts reveals that the panel fitting differs from the upright fitting. The method has localized the obstruction. Available continuations include obtaining a compatible panel, developing an adapter with usable connection rules, or choosing another assembly design. “Assemble the display” alone does not select among them.

Suppose a compatible panel is supplied. The recovered design now connects the three components in the required order. Portability is still assessed against the actual carrying requirement, and stability against the loading and support conditions. Those engineering questions can change the design, but they are distinct from the recovered answer about how its parts connect.

The first useful result is the assembly design or the fitting mismatch that prevents it. Physically assembling and testing the stand are subsequent work selected by the intended use.
