Pins TRIZ Cases
- Tolerance-Compensating Connection Arrangement for Two-Axis Alignment
A nut, compensating element, and elastic clamping fork absorb longitudinal and transverse assembly tolerances while keeping component attachment secure.
- Sealant Flow Cap Structure for Fastener Leakage Control
A protuberance-guided cap routes sealant around a fastener cavity, vents trapped air, and prevents cap lift and leakage during lightning exposure.
- Pre-Assembled Connecting Element for Loss-Safe Friction Coupling
A temporary elastic fixing element pre-assembles the connector, prevents loss during handling, and preserves static friction in assembly.
- Pre-Mounting Sleeve Locking for Pin-Shaped Connecting Elements
A recessed sleeve locks pin-shaped connectors in plain through-holes, avoiding complex lug machining, chips, and pull-out during pre-assembly.
- Locking Clasp Cable Assembly to Prevent Medical Cable Removal
A locking clasp with stop sleeves and a coated wire rope secures medical device cables against unauthorized removal and waste.
- Shearing Fastener Plug for Sealing Inaccessible Fastener Holes
A torque-shear neck lets a threaded plug be installed from the exterior and left in the bore to seal inaccessible fastener holes and stop leaks.
- Rivet-Like Fastener Assembly for Sealed Spin-Resistant Sheet Joints
An elastomeric seal and deformable shank create a water-tight, spin-resistant threaded joint in thin sheet materials.
- Turbocharger Adjustment Screw Cover for Tamper-Proof Performance
A fixed cover and irremovable cap block access to turbocharger flow adjustment screws, preventing unauthorized tuning and exhaust changes.
- Rotor Shaft Locking Assembly With Retainer Anti-Loosening Fit
A bore-fitted retainer biases the lock nut against the gear, cutting shim-heavy assembly time while improving rotor shaft retention.
- Spring-Loaded Captive Fastener for Tool-Free Withdrawal Locking
Spring-loaded pins retract during insertion and expand after passing an aperture, locking the fastener in place without tools or extra parts.
- Flexible Screw Retainer and Split Washer for Repeated Fastening
An elastic retaining aperture and split washer reduce wear during repeated screw removal while keeping standard screws securely attached.
- Rotating Protective Cap for Anti-Tamper Threaded Adjustment
A freely rotating protective cap blocks tool access to engine adjustment threads, preventing unauthorized parameter changes while allowing factory setup.
- Flanged Bracket Mounting for Single-Handed Component Fixing
A flanged bracket and pre-assembled screw-washer coupling let heavy technical components be rotated into place and fixed by one installer.
- Dual-Adhesive Fastening Element for Stable Composite Bonding
Separated adhesive layers and a release liner prevent premature cross-linking, enabling stable composite fastening without cold-chain storage.
- Hands-Free Support Bolt With Catch Bar Fixture Retention
A pivoting or expandable catch bar keeps a fixture on a threaded rod during mounting, reducing manual support, time, and damage risk.
