Washers TRIZ Cases
- Air Spring Fastening With Plastic Acoustic Decoupling
Plastic parts isolate the air spring from the vehicle body to block structure-borne noise while keeping fastening secure and simple.
- Vehicle Seat Attachment Profile With Self-Aligning Floor Connection
A movable connecting element self-aligns with the floor holding element to absorb tolerances while maintaining symmetrical crash support.
- Aircraft Seat Transmission Locking for Crash Load Absorption
Prestressed elastic elements engage braking faces under threshold axial load, protecting aircraft seat drives from crash forces without oversizing.
- Modular Touch-Proof Screw for Adaptable HV Plug Connections
A modular screw body and insulating touch protection element fit varied HV connector geometries while keeping one tool interface and safe handling.
- Touch-Proof Plug Screw With Modular Insulating Tip
A two-part screw separates the standard fastener from the insulating touch guard, improving geometry adaptability in high-voltage plug connections.
- Flexible Bicycle Suspension Spacer for Eyelet Fit and Low Friction
A compressible press-fit spacer stabilizes the suspension eyelet, cuts friction and wear, and blocks contamination without extra O-rings.
- Wheel Beadlock Clamping for Low-PSI Tire Retention
A pivoting ball-seat bolt and fulcrum bead ring reduce bolt stress while locking low-psi tires against slip and bead failure.
- Conductive Fastener Coating for CFRP FSDA Lightning Protection
Conductive gap filler and coated fasteners maintain lightning current paths in misaligned CFRP FSDA holes, cutting assembly time and cost.
- Conical Wedge Washer Structure for Wood Shrinkage Loosening
A compressed annular wood wedge inside a conical washer offsets timber shrinkage and sustains bolt clamping force in wooden joints.
- Releasable Walkway Clamp for Drill-Free Frame Attachment
A two-part clamp secures walkway panels to support frames without drilling, enabling faster installation, removal, and underside access.
- Service Tube Locking Assembly for Vibration-Resistant Threaded Joints
A ramp-guided locking member and fastener keep aircraft engine service tube threads from loosening under vibration, impact, and thermal loads.
- Conical Wedge Washer for Wood Shrinkage Compensation
A compressed annular wooden wedge inside a conical washer offsets wood shrinkage and preserves long-term bolt clamping force.
- Tolerance Compensation Assembly for Play-Free Component Joining
A conical base and compensating element use wedging and friction to absorb assembly tolerances while creating play-free, self-locking joints.
