Emergency Actuators TRIZ Cases

Back input part moves physical buttons to the rear housing, eliminating front bezel width constraints while preserving tactile user input functionality.

Segmented keys tilt or rotate to expand the selection surface, preventing accidental presses while reducing user fatigue during typing.

Segmenting the reed into two energy storage components prevents contact failure and equipment damage from sparking.

Segmenting deflection webs resolves the contradiction between tactile feedback and moisture protection in miniaturized handheld devices.

Gyro modules and tactile switches detect wrist rotations to select characters, resolving usability issues caused by tiny physical keys.

A key switch uses magnetic attraction to position the cap without rubber.

Capacitive sensor replaces pressure-sensitive resistance measurement to eliminate dispersion in tilt angle determination accuracy.

An integrally formed plunger assembly replaces separate hinge pins and bias springs in circuit breaker accessories.

A slider moves relative to a holder to adjust interference between a pressure part and segment adjusting structure on a scroll wheel.

Lenses embedded in scissor mechanisms direct light precisely to individual keycaps, reducing power consumption and heat generation.

A compact control apparatus uses a single magneto rheological fluid system to adjust operational feel across multiple moving members.

A segmented smart switch module fits inside standard electrical boxes while a full-size control panel covers the opening for user interaction.

A detachable lateral keyswitch mechanism uses rotating portions to enable easy assembly and rework.

Mounting the light source and tact switch on opposite PCB sides resolves the trade-off between uniform light transmission and proper button press feedback.

Shape memory alloy wires retract and extend keyboard keys through resistive heating, replacing mechanical actuators that fail under repeated stress cycles.

Segmented guide grooves and dynamic projections resolve the trade-off between uniform position setting and low sliding load in press buttons.

A keyboard device uses a film actuator to generate repulsive force.

A key structure employs a soft top stopper in the position-limiting structure to reduce stabilizer bar collision noise during rotation.

Sensing device detects tapping frequency on light emitting keys to produce color control signals that indicate user health state and reduce fatigue risk.

Segmented rib guides decouple mechanical movement from optical paths, ensuring consistent perimeter illumination without twisting or binding.

A key switch device integrates the light guide within a base opening to reduce height.

A backlit key assembly embeds a light source in a backing plate recess, reducing device thickness while maintaining backlighting functionality.

A disc-based switching mechanism uses a single actuator to rotate bias and switch discs for fast double throw operation.
