Engineering Safety Devices TRIZ Cases
- Relay Control Circuit Positive Feedback Timing
A relay control circuit uses positive feedback to maintain activation duration for reliable switching operations.
- Magnetic Antenna Sensor for Wood Machining Safety
Antenna sensor detects magnetic field distortion to stop movable parts, preventing operator injury while maintaining high machining speeds.
- Safety Sensor Reference Contour for Automated Protective Field Monitoring
A safety sensor determines a reference contour during teach-in to monitor configured protective fields.
- Palletizer Safety Device Distinguishing Pallets from Intruders
Adaptive detection elements differentiate pallet transport from intruders, preventing false alarms while maintaining safety during operation.
- Machine Tool Door Torque Detection Safety
A machine tool door drive uses disturbance torque estimation to detect abnormal loads during movement.
- Access Control System for Robot Interference Area
Indicating lamps define interference area boundaries while a control device manages gate locking based on robot operation.
- Wireless Projector Auto-Darkening Welding Helmet
A micro-projector projects operating parameters onto the visor, allowing adjustments without removing the helmet to reduce eye strain.
