Optical Detection TRIZ Cases
- Photoelectric Sensor Housing Design for Compact Operability
Distributing controls across inclined surfaces resolves the contradiction between miniaturization and operability in compact photoelectric sensors.
- Room Entry Detection Using Door State and Person Sensors
Combining pyroelectric infrared and acceleration sensors reduces device complexity while maintaining high detection accuracy for room entry and exit monitoring.
- 3D Posture Recognition Using Polarized Light Modules
Polarization modules determine 3D posture and location by analyzing polarized light intensity, overcoming indoor signal interference.
- Sensor Orientation Detection via Integrated Gravity Sensor
A sensor integrates a gravity sensor to detect spatial orientation relative to gravity for automatic function selection.
