Contact Surface Shape/Structure TRIZ Cases

Elastic tongues penetrate hollow portions to establish contact between conductive traces on dual membranes.

Projections on the key top contact a receiving portion on the base plate, mitigating bottom-out feelings by cushioning impacts before they reach the sheet.

Hollow contact arm body with internal fins directs airflow to dissipate heat.

Elastic deformation of the contact element secures the busbar without screws, eliminating complex fastening steps during installation.

A hollow cylindrical contact reduces moving mass to damp vibrations, preventing temporary disconnections during dynamic switching operations.

Deformable ribs on a medical handpiece sleeve contact internal conductive pads to activate the device, eliminating foot pedals and enabling grip changes.

Concave substrate structures hold carbon nanotube electrodes, eliminating complex vacuum deposition steps and reducing production costs.

A carbon nanotube structure replaces indium tin oxide to deliver uniform resistance and mechanical durability in touch panels.

A touch-sensitive surface activation device detects applied load to control vehicle opening mechanisms.

Angled contact bridge geometry converts impact energy into scraping motion that removes dirt and oxide layers from contact surfaces.

Segmented arms pivot on an armature to distribute control force uniformly, preventing panel tilt during operation.

Segmented contact surfaces reduce temperature hotspots and arcing risks by distributing contact force across multiple spots.
