Nuts TRIZ Cases
- Segmented Expansion Bolt for Multi-Material Wall Anchoring
A segmented expansion bolt adapts to friable or compact walls by distributing load through localized deformation, reducing internal surface damage.
- Profile Element with Inwardly Bent Flanges for Dual-Side Anchoring
Elongate profile element features inwardly bent flanges and oblong recesses to secure anchoring elements on both upper and bottom sides.
- Tapered Guide External Thread Member for Oblique Entry Prevention
External thread member with a tapered guide portion and guide screw thread corrects inclination during engagement.
- Innerduct Cutting and Removal System for Conduit Space Recovery
Longitudinal segmentation of innerducts allows removal without severing live cables, recovering conduit space for new installations.
- Self-Tapping Screw Thread Segmentation for Torque and Fastening
Segmented thread design reduces driving torque by minimizing flank contact, ensuring sufficient fastening force in soft materials without cracking.
- Segmented Locking Nut and Keyed Washer for Articulating Joints
Offset nut apertures align with a keyed washer during rotation, preventing loosening in articulating joints without complex locking mechanisms.
- Rail Fastening Device with Stop Elements for Orientation Control
Stop elements constrain the rear-engagement member's rotation to prevent overtwisting and ensure secure clamping on varying rail geometries.
- Wood Screw With Segmented Thread And Nibbed Head
Segmented threads and head nibs reduce torque while maintaining structural integrity.
- Self-Retaining Anti-Rotation Key for Vibration-Resistant Fasteners
A resilient flex arm with a locking tip prevents stud rotation and disengagement under vibration or thermal expansion while allowing easy removal.
- Metal Plate Fixation via Reflow Soldering Barrel and Disposable Cap
Segmenting the metal barrel for reflow soldering from the plastic cap prevents spring tempering, preserving structural strength during installation.
