Building Braking Devices TRIZ Cases
- Lever Arrangement Power Supply for Door Wings
Integrated lever contacts supply power to door wings, eliminating visible transition cables that increase assembly effort and damage risk.
- Viscous Fluid Cushioning Device for Sliding Shutters
A viscous fluid rotary braking device regulates sliding shutter travel using fluid drag resistance.
- Split Tailgate Door Collision Avoidance Control
Powered split tailgate control prevents door collisions by detecting shared zones and reversing movement or holding position.
- Furniture Hinge Rotation Damper Using Transmission Mechanism
An articulated lever drives a slide through a transmission mechanism to actuate a rotary damper, enabling effective damping across large opening angles.
- Slider Element Snap Fit Assembly for Door Closer Guiding Arm
A slider element bearing area uses snap fit sections to secure a guiding arm without screws.
- Liquid Sealed Damper With Recessed Partition Member
A liquid sealed damper uses a recessed inner gap in the partition member to nest the diaphragm and reduce overall size.
- Sliding Door Lateral Sealing Wedge Mechanism
Wedge track and follower draw sliding door laterally against partition to seal gaps blocking noise and light.
- Door Closer Diagnostics Using Motion and Load Data Analysis
A door closer diagnostics system captures motion and load data to determine precise hydraulic adjustments.
- Door Stop Unit Decoupling Mechanism for Noise Reduction
A decoupling device actuated by a door closer slider releases the locking mechanism from holding control to allow smooth operation.
