Pins TRIZ Cases
- Transport Screw Helical Groove Blank Feeding Accuracy
A transport screw with a helical groove moves blanks into thread rolling machines using friction-driven rotation.
- Elastic Sleeve Fastener for Secure Through-Hole Insertion
Deformable holding elements perform evasive movement upon insertion, preventing deep placement and ensuring secure locking within the through-hole.
- 3D Printed Components With Integrated Captive Fasteners
Additively manufactured components integrate captive nuts and pins to enable precise mechanical interconnections between printed parts.
- Elastic Holding Disk for Fastening Stud Tolerance Compensation
An elastic holding disk compensates for fastening stud position tolerances through controlled deformation, preventing undesired loosening during operation.
- Resilient Position Indicator for Wheel Nuts
A resilient position indicator compresses to fit wheel nuts and expands for secure mounting.
- High-Frequency Device Fastening with Anti-Loss Screw and Stop
A stop and counter-holder system maintains alignment during transport, eliminating manual positioning errors during installation.
- Tool-Free Retention Clip With Cam Handle For Aircraft Maintenance
A retention clip with a cam handle enables manual operation without external tools.
- Flywheel Screw Retention via Radial Deformable Rings
Radial deformable rings secure flywheel screws without increasing axial size, solving space constraints in dual clutch transmissions.
- Captively Mounted Nut for Chain Saw Bar Attachment
Axial play in the captive nut prevents loss while enabling sequential detachment of multiple bolts on large chain saws.
- Captive Washer Sleeve with Dual Constrictions for Axial Control
Dual constrictions on the sleeve prevent screw detachment and limit axial displacement during assembly.
- Bushing Assembly with Curved Nose and Ribs
The rounded nose distributes insertion force over a larger area, preventing stress concentration and cracking in plastic components while maintaining fastener alignment.
- Travel Assembly Spline Connection and Bolt Limiting
A travel assembly uses a spline connection between the spindle and carrier to transmit rotation while reducing component count.
- Sealing Plug With Internal Fluid Cavity For High Pressure
An internal cavity channels external fluid pressure against the elastic body, boosting closing force to seal concrete holes without complex installation.
- Elastic Connecting Flange Captive Screw Retention
Asymmetric shaft geometry with elastic walls secures screws without tight manufacturing tolerances, reducing production costs.
- Spill Containment Floor with Sealed Floating Fasteners
Larger floor apertures paired with non-circular fasteners resolve alignment precision trade-offs while hermetically sealed chambers contain fluid spills.
- Bolt Retention Clip for Gas Turbine Engine Rotor
Segmented bolt retention clips prevent disengagement during blind assembly by distributing load across multiple contact points.
- Shackle Guard Tether Prevents Pin Detachment
A shackle guard with a tether fastener secures the closure pin to prevent accidental detachment.
- Vented Dock Float Pentane Gas Pressure Management
A vented dock float releases trapped pentane gas through a segmented plug, preventing polystyrene expansion and structural deformation.
- Reusable Push-In Fastener With Nested Pin And Deflectable Legs
Nested pin and deflectable legs solve pre-drive instability, enabling easy disassembly without damage.
- Reaction Washer for Threaded Fastener Side Load Mitigation
Dual friction reaction washers eliminate side loads and thread galling during high-speed industrial bolting operations.
- Steering Lock Bolt Security via Counterbore Recess
Deep counterbores conceal the bolt head within the aluminum flange, blocking shock tools and securing the steering lock against theft.
