Nuts TRIZ Cases
- Modular Screw Captivator With Keyway Locking Mechanism
Segmentation of the captivator into separable body and retainer components reduces inventory costs while maintaining structural integrity for field repairs.
- Self-Attaching Fastener Barrel Deformation Against Planar Die
Axial collapse of the tubular barrel against a planar die eliminates lubrication needs and prevents cracking, reducing manufacturing costs.
- Locking Structure With Chamber Slot For High Tensile Strength
A locking structure uses a chamber and slot to combine with workpiece material, increasing surface area for stronger assembly.
- Pitch Diameter Displaced Screw Thread Asymmetry
Asymmetric thread ridge and groove widths displace the pitch diameter, reducing internal screw tensile stress by 27% and preventing breakage.
- T-nut Collation via Mechanical Interlock and Progressive Die
Replacing adhesive tape with mechanical interlocks resolves detachment caused by temperature changes while maintaining structural rigidity.
- Threaded Engagement Device with Curved Load Flanks
Curved load flanks and optimized root radii reduce stress concentration at thread roots, preventing damage during loosening forces.
- L-Shaped Bolt Rotation Prevention in Closed Connectors
An L-shaped bolt with a stopping member prevents rotation during fastening.
- Lug Nut Holder With Cam-Actuated Retract Fingers
A lug nut holder uses a cam guide to drive retractable fingers for secure fastener retention.
