Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing lighting devices are used to address biorhythmic disturbances, then lighting effectiveness is improved, but device size becomes large and causes photophobia
Solution Approach 1:
The lighting device is divided into a first body containing the light source unit and a second body containing the sensor unit, which can be separated or combined. This segmentation allows the device to maintain full functionality while reducing the size of each individual component, making it more portable and comfortable to wear without causing photophobia.
2Reliability
If existing lighting devices are used to address biorhythmic disturbances, then lighting effectiveness is improved, but ease of operation deteriorates
Solution Approach 1:
The device incorporates sensor units that automatically detect posture and position, and the control unit automatically adjusts light emission based on these detections. This self-service mechanism eliminates the need for manual operation, making the device extremely convenient to use while maintaining effective biorhythmic lighting support.
3Ease of operation
If portable design is implemented, then ease of operation is improved, but lighting effectiveness may deteriorate
Solution Approach 1:
The device dynamically adjusts its lighting characteristics based on real-time sensor feedback about posture and position. The control unit modifies light emission parameters according to the detected conditions, ensuring that lighting effectiveness is maintained regardless of the device's portable form factor or the user's movements.
