Traffic Gates TRIZ Cases
- Rail Crossing Gate Counterbalance Using Motor Current Sensing
Motor current and speed sensing determine crossing gate counterbalance without manual torque checks, improving adjustment safety and gate reliability.
- Railroad Crossing Gate Obstruction Detection Through Motion Feedback
Motion sensing and controller feedback detect crossing gate obstructions early, preventing over-current damage and improving gate reliability.
- Gate Crossing Motor Direction Control With Relay-FET Logic
Relay-switched FET outputs reverse a gate crossing motor while adding fault detection to improve reliability and reduce maintenance.
- Gate Crossing Main Shaft Bearing Removal Without Full Disassembly
A keyed bearing tool extracts gate crossing main shaft bearings in the field without full disassembly, reducing service time and damage risk.
- Impact-Rotating Barrier Boom Hinge for Railway Crossing Safety
A hinged barrier boom rotates under impact yet stays connected, protecting the drive unit and enabling automatic continuity alerts.
- Railroad Crossing Gate BLDC Control With Voltage-Adaptive PWM
Voltage-aware PWM and PID feedback keep railroad crossing gates moving consistently across supply changes while enabling obstruction detection.
- Railroad Crossing Gate Height Adjustment Assembly
Segmented smooth pipe and sliding coupling adjust railroad crossing gate height, eliminating labor-intensive wiring conduit replacement during road repairs.
- Tamperproof Railroad Crossing Gate Mechanism
Mechanical linkage locks railroad crossing gate arms horizontally, preventing pedestrian tampering and ensuring barrier integrity.
- Barrier Boom Balance Mechanism Without Counterweights
A barrier boom uses compression springs to achieve static and dynamic balance without bulky counterweights.
- Waterproof Sensor Box for Barrier Accident Reconstruction
A sealed waterproof box merges motion, shock, and GPS sensors to timestamp accident parameters for liability determination.
- Railroad Crossing Gate Height Adjustment Using Threaded Pipe Extension
Threaded pipe extension lengthens wiring conduit to raise gate height, eliminating time-consuming rewiring and labor costs during maintenance.
