Contact Operating Parts TRIZ Cases
- Door-Mounted Rotary Handle With Busway Interlock Status Indication
A door-mounted rotary handle uses a cam-driven interlock to secure busway engagement while switching the device and showing on, off, or tripped status.
- Bi-Stable Transfer Switch Sequencing for Safe Source Overlap
A spring-charged bi-stable transfer switch uses latch release and breaker coordination to control overlap, prevent back-feed, and avoid unsynchronized transfer.
- Keyboard Keyswitch Gear Link Structure for Stable Off-Center Pressing
A gear link support keeps the keytop moving vertically under off-center presses, stabilizing multiple membrane contact pairs.
- Machine Tool Switch Interlock Using Sequential Magnetic Actuation
A magnetic sequential switch interlock prevents accidental machine tool activation while reducing the complexity and cost of mechanical linkages.
- Keyboard Key Stabilizer Structure With Flexible Hooks for Noise Reduction
Flexible hooks buffer contact between a keyboard key stabilizer bar and keycap, cutting noise while preserving tactile feedback and assembly ease.
- HVDC Relay Drive Structure for Easier Assembly and Arc Isolation
A stacked drive structure simplifies HVDC relay assembly while an arc isolation stopper helps prevent reverse arc damage and extend relay life.
- Keyboard Linkage With Inclined Sliding to Reduce Keycap Wobble
Inclined guide bevels shift keycap support from horizontal to angled sliding, boosting reaction force and reducing wobble during pressing.
- Industrial Button Cover Structure for Impact-Resistant Protection
A sleeve-and-divider button cover redirects impact loads to the panel and housing, reducing button damage, downtime, and accidental actuation.
- Rotary Hammer Mode-Linked Trigger Lock for Hammer-Only Use
A mode-linked lock and linkage hold the trigger on in hammer-only mode, enabling continuous motor operation without disabling variable speed in rotary mode.
- Scissor Key Structure With Acoustic Feedback in Thin Keyboards
A scissor key uses an elastic piece to generate click sound during actuation, improving typing feedback without adding keyboard thickness.
- Optical Keyswitch Structure for Wear-Free Triggering in Thin Devices
An emitter-receiver keyswitch uses a sliding frame to block light, avoiding contact wear while keeping thin, repairable keyboard designs.
- Vehicle Touch Sensor Bracket Locking for Fast Precise Mounting
An elastomer locking insert replaces adhesive tape to speed vehicle touch sensor mounting and reduce position variation.
