Contact Surface Shape/Structure TRIZ Cases

Elevating members lift a dome periphery from a mounting surface, resolving the trade-off between compact footprint and noticeable tactile feedback.

A double-layer electrode device uses cross-connected layers to form thicker electrodes with lower resistance.

Edge-mounted PCB capacitance sensors detect user engagement through integrated switching circuitry.

A multidirectional input member uses a looped sensor and tapered rubber protrusion to detect pressing location.

Curved contact surfaces reduce friction to prevent blocking, allowing compact drive devices in high-voltage applications.
