Sliding Wall Rail and Switch Extrusion for Visual Uniformity

The patent applies homogeneity by making both rails and switches from extruded profiles with identical extrusion directions. This ensures that adjacent visible surfaces have the same microstructure and visual appearance, eliminating the visual discontinuity that would result from mixing extruded and machined components. The homogeneous manufacturing approach creates a uniform ceiling guide appearance while maintaining functional performance.

The patent merges the manufacturing approaches by making both rails and switches from extruded profiles rather than mixing extrusion and machining processes. This combination ensures that both components have matching surface microstructures and visual appearances. The switching function is achieved through the geometry of the extruded profile itself rather than through machining operations, thereby maintaining visual consistency while preserving functional precision.

The patent applies parameter changes by optimizing the extrusion process parameters to achieve both aesthetic appearance and functional precision simultaneously. By controlling extrusion direction, surface finish, and profile geometry during the extrusion process itself (rather than relying on subsequent machining), the system achieves dimensional accuracy and visual uniformity without contradiction. The extrusion parameters are tuned to produce the precise geometries needed for switching functionality while maintaining uniform visual appearance.
