Screws TRIZ Cases
- Blind Rivet with Breakable Mandrel for Tack Fastening
A blind rivet uses a segmented mandrel to crimp a tapered sleeve, creating high installed tension during assembly.
- Thread-Cutting Concrete Screw with Angled Longitudinal Grooves
Angled longitudinal grooves extract rock flour to reduce friction and lower the screwing torque required for concrete installation.
- Self-adjusting fasteners for headlamp assembly tolerance compensation
Self-adjusting fasteners automatically compensate for irregular spacing between a headlamp and its mounting brace, reducing manual adjustment time and costs.
