Washers TRIZ Cases
- Ultra High Strength Screw Yield Ratio via Austempering
Austenempering produces a bainite structure with a yield ratio of at least 0.95, enabling precise yield point detection and consistent clamp load maintenance.
- Threaded Insert Positioning in Composite Molds
Partially threaded pins secure inserts during composite curing, resolving alignment and extraction contradictions.
- Rounded Cleat Roofing Membrane Plate Wear Reduction
Rounded terminal surfaces on injection-molded roofing plates prevent punctures and minimize wear by eliminating sharp edge stress concentrations.
- Compression Resistant Component With Embedded Limiter
Embedded elongated limiters with higher compressive modulus bear fastener loads, reducing weight by 95% compared to steel.
- Sealing Screw with Support Thread and Elastomer Washer
A sealing screw uses an elastomer washer and sealant to maintain thread engagement.
- Breakaway Bushing Presets Securing Member for Metal-on-Metal Fastening
A breakaway bushing maintains a securing member in an upright position, then separates to enable direct metal-on-metal contact and prevent stripping.
- Plastic Fastening Element with Cast Metal Thread for Condensation Control
A plastic fastening element incorporates a cast metal threaded bush to secure facade components without forming cold bridges.
- Fastener Dry Dielectric Coating for EME Protection
Pre-applied dielectric coatings on fasteners eliminate time-consuming sealant curing while reducing aircraft weight and preventing lightning-induced arcing.
- Modular Nut Plate Radial Expansion for Variable Opening Lengths
Radial expansion of a multi-piece tubular section accommodates varying workpiece opening lengths, eliminating the need for multiple bracket sizes.
