Construction Fastening Devices TRIZ Cases
- Window Fitting Variable Coupling Mechanism
Variable coupling rods reverse pivot movement directions to lock sashes in closed and tilt positions, reducing manufacturing complexity.
- Compact Planetary Gear Door Closer for Reduced Axial Thickness
A compact planetary gear door closer reduces axial thickness through a nested sun and sector gear arrangement.
- Mortise Lock Gear Transmission Compact Design
Overlapping gearwheel and pinion arrangement reduces built-in length while distributing forces evenly across multiple contact zones.
- Transformer Room Door Interlock via Ground Switch Cam
A slidable shaft and spring link the ground switch cam to an interlock plate, restricting door access.
- Multi-Stage Interlock with Reduction Gear for Luggage
A multi-stage interlock uses reduction gears to lower locking effort and springs for audible feedback.
