Emergency Casings TRIZ Cases
- Guard Member with Acute-Angle Petals for Circuit Breaker Safety
Acute-angle petal portions on a guard member shield live conductors, preventing operator contact and ensuring UL certification compliance.
- Fusible Link Unit Cover Fixing Against Vibration Rattle
A fusible link unit secures its fuse cover between the battery and a deck board to prevent rattling.
- Rotatable Terminal Block Lockout Device for Worker Safety
A rotatable lockout device secures terminal blocks using aligned sections and a hinge rod mechanism.
- Key Device Chassis Rib Reduction for Miniaturization
A key device chassis uses a single rib set to divide the opening, allowing keys to be arranged closely within the reduced volume.
- Removable Dielectric Shed Sleeve for High Voltage Switch
Removable shed sleeves prevent voltage flashover by increasing creep distance without permanent bonding, reducing maintenance costs.
- Contamination Resistant Push Button Switch Operator Assembly
An oversized housing opening allows the switch operator to extend freely while a rearward collar blocks ingress and a drain port removes accumulated detergent.
- Electronic Key Switch Housing with Flexible Diaphragm
A flexible diaphragm seals apertures in a rigid frame to transmit force to internal switches.
- Switch Guide Wall Cutouts for Liquid Flow and Smooth Operation
Segmented guide walls with cutouts prevent liquid clotting in the operating unit gap, ensuring reliable switch operation under exposure.
- Aircraft Switch FOD Protection via Elastomeric Seals
Elastomeric seals and silicone gel prevent debris intrusion in aircraft switches, maintaining mechanical movement while blocking contamination.
- Push Switch Holder Aligns Driving Protrusion
A perforated holder aligns the driving protrusion with the reversing spring center, eliminating positional deviation and adhesive cracks.
- Relay Unit Heat Dissipation via Segmented Cover
A segmented relay cover uses a high thermal conductivity lower member to transfer heat from the bus bar.
- Waterproof Keyboard Base Plate with Pre-Cut Attachment Holes
Pre-formed cut lines in the waterproof sheet enable hook members to break through for secure attachment while maintaining liquid resistance.
- Keyboard Liquid Expelling via Inverted-Trapezoid Engaging Ear
Inverted-trapezoid holes in keyboard engaging ears guide liquid flow outward through block walls, preventing short circuits from accumulated fluid.
- Keyswitch Device Component Reduction via Hooked Bracket
A keyswitch device uses a hooked fixing bracket to secure the micro switch and guide the keycap.
- Switchgear Single Operating Mechanism Multi-Position Control
A switchgear uses one operating mechanism to move a movable contact between three or more positions.
- Low Travel Switch Assembly Tuning Members
Tuning members integrated into a domed surface adjust physical parameters to maintain reliable tactile feedback despite reduced key cap travel distance.
- Terminal Side Key Waterproofing via Interference-Fitted Sealing Ring
Segmented components simplify assembly while maintaining high-grade waterproofing for mobile phone side keys.
