Vehicle Seat Fan Case Module Orientation Restrictor

The patent applies asymmetry by providing ribs with different shapes at different positions on the first case. Specifically, a first rib has a different shape from a second rib, creating an asymmetric configuration that only allows the second case to be assembled in the correct orientation. This asymmetric design prevents incorrect assembly while maintaining a relatively simple assembly process.

The ribs act as intermediary elements between the first case and the second case. These ribs protrude from the first case and engage with corresponding recesses or features on the second case, serving as a mediating mechanism that guides the assembly process and ensures correct orientation without requiring complex assembly procedures.

The patent applies local quality by making the ribs flexible rather than rigid. This local flexibility allows the ribs to deform or yield when they come into contact with surrounding components like harnesses during the assembly process. The ribs maintain their restrictive function for incorrect orientation while locally adapting to avoid damaging other components.

The patent changes the physical parameter of the ribs from rigid to flexible. This parameter change allows the ribs to perform their orientation-restriction function while simultaneously avoiding damage to surrounding components. The flexibility parameter enables the ribs to bend or deform under load, preventing harmful interference with harnesses and other nearby parts.
