Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If individual calibration is performed for each location, then optimal lighting conditions can be achieved at that location, but the system becomes complex and requires recalibration after any relocation or furniture rearrangement
Solution Approach 1:
The patent applies universality by creating a calibration-free light regulation system that works universally across different locations without requiring location-specific calibration. The system uses multiple optical sensors to detect light incidence from various directions and a control device with stored transfer functions that automatically adapt to different spatial configurations, eliminating the need for manual calibration at each location.
Solution Approach 2:
The system implements self-service through automatic adaptation mechanisms. The control device automatically processes sensor inputs and adjusts light sources based on pre-stored transfer functions that model the relationship between sensor readings and optimal lighting conditions. This self-adjusting capability eliminates the need for user intervention or recalibration when the system is relocated or when furniture is rearranged.
2Manufacturing precision
If manual recalibration is required after relocation, then lighting conditions can be optimized for the new location, but time is lost and productivity decreases
Solution Approach 1:
The patent applies preliminary action by pre-storing multiple transfer functions in the control device that correspond to different spatial configurations and light incidence patterns. These transfer functions are prepared in advance during system manufacturing, enabling the system to immediately adapt to new locations without requiring on-site calibration. The control device selects the appropriate transfer function based on sensor inputs, allowing instant optimization of lighting conditions.
3Ease of operation
If the system is designed for universal application without calibration, then ease of operation improves, but measurement precision of light incidence may be compromised
Solution Approach 1:
The patent applies segmentation by using multiple optical sensors positioned to detect light incidence from different directions (e.g., front, rear, left, right, top, bottom). Each sensor provides directional light incidence data, and the control device processes these segmented measurements collectively using stored transfer functions to determine optimal lighting conditions. This multi-directional sensing approach maintains measurement precision while enabling universal, calibration-free operation.
