Rivets TRIZ Cases
- Blind Fastener Bulb Separation for Blind Side Engagement
A blind fastener sleeve forms a bulb that separates from its body to expand diameter and engage the blind side of workpieces.
- Rivet Fastener Pin Head Design for Confined Space Installation
Elongated rectangular rivet pin head with narrow grip sides accommodates finger access in recessed cavities, resolving installation bottlenecks.
- Blind Rivet Mandrel Head Asymmetric Elliptical Cross-Section
Asymmetric mandrel head with elliptical cross-section prevents broken mandrel dropping while maintaining fastening strength.
- Single-Groove Short-Tail Rivet Stress and Engagement
A single-groove short-tail rivet uses a smooth cambered broached groove to enable automatic claw engagement.
- Clamping Rivet Threaded Ring Spring Arm Blocking
Segmenting the base shaft with a partial threaded ring prevents radial deflection, securing pre-assembly position against high pull-out forces.
- Lockbolt Single Pull Groove Design for Alignment and Strength
A lockbolt pin with a single large pull groove simplifies tool alignment and reduces debris accumulation during installation.
- Scandium Aluminum Alloy Fastener Weight Reduction
Scandium aluminum alloy fasteners replace steel to cut vehicle mass while maintaining corrosion resistance and mechanical integrity.
- Lockbolt Single Pull Groove Design for Debris Resistance
A lockbolt pin uses a single large pull groove to engage the installation collet, simplifying tool alignment and reducing debris accumulation.
- Bi-metal Z-pin thermal locking for composite delamination
Thermal expansion transforms a straight Z-pin into a locking shape, preventing fiber damage and enhancing structural integrity.
- Fastening Device Welding Shaping Reduces Milling Waste
Welds a head part to a shaped shaft part, replacing milling operations that consume excessive material and time.
