Nuts TRIZ Cases
- Adjustable Hanger Hinge Locking Mechanism for Folding Doors
A hanger hinge uses a sleeve and locking member to secure the bolt position during height adjustment.
- Self-Locking Screw Connection With Resilient Catch Grid
Resilient sheet-metal catches engage a grid on an intermediate washer, enabling precise axial adjustment and easy mounting without complex assembly steps.
- Ceramic Composite Fastener for Thermal Stress-Free High-Temperature Joints
A fiber-reinforced ceramic composite fastener with a dove-tail shank and matched thread forms joins structural members without thermal stress.
- Pickup Truck Bed Mounting Assembly Without Drilling
A planar plate with a T-mount engages an anchor plate to secure accessories without drilling holes.
- Dual-Prevention Lock Device for Screw Safety
A dual-prevention lock device secures screws using upper and lower clamping parts driven by a lock core.
- Wheel Nut Arc Surface Design Prevents Deformation
Replacing flat surfaces with an outward protruding arc surface increases contact area, preventing deformation and looseness during repeated disassembly.
- Clevis Pin Assembly With Internal Lubrication Channel
An internal channel within a clevis pin receives lubricant via a fluid fitting, preventing seizing in air brake couplings without adding external complexity.
- Split Bolt Retaining Device Anti-Vibration Locking Mechanism
A retaining device with bendable tabs engages split bolt slots to prevent nut loosening from vibration and thermocycling.
- Thread-Cleaning Nut With Integrated Bristles For Corrosion Removal
Integrated bristles abrade corrosion from threaded members during rotation, eliminating the need for specialized tools in tight spaces.
- Retaining Spring Nutplate for Restricted Aircraft Access
Flexible body maintains retaining device alignment using spring force, eliminating specialized tools in restricted aircraft areas.
- Helical Segment Fastener Resists Loosening Torque
Segmented helical bearing surfaces resist loosening torque without damaging mating parts or requiring additional components.
- Adjustable Shielding Fastener with Deflectable Plates
Deflectable plates adjust barb clearance to enable removal without damaging studs.
- Fiber-Reinforced Plastic Threaded Bolt Manufacturing
Deforming a fiber-reinforced plastic blank in a negative mold forms threads without severing fibers, reducing weight while maintaining strength.
- Fastener Head Lubricant Coating Reduces Driver Blade Wear
Applying a solid lubricant to the fastener head creates a protective barrier that minimizes frictional wear on the driver blade, extending tool life.
