Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform illumination is used during vehicle accidents, then the illumination system is simple to operate, but biometric information cannot be obtained under certain imaging conditions
Solution Approach 1:
The illumination system dynamically adjusts lamp color based on detected biometric information types. The control unit changes illumination characteristics in real-time according to the imaging conditions and required biometric data, transforming a static uniform illumination system into an adaptive dynamic system that optimizes for specific measurement requirements.
Solution Approach 2:
The system changes physical parameters of illumination (lamp color, wavelength) based on the type of biometric information to be acquired. By adjusting illumination parameters according to specific imaging conditions and biometric information types, the system overcomes the limitation of uniform illumination and enables accurate biometric measurement under various conditions.
2Measurement precision
If lamp color is changed based on biometric information types, then biometric information can be accurately acquired, but the illumination control system becomes more complex
Solution Approach 1:
The control unit serves multiple functions: it detects accident conditions, identifies biometric information types, determines optimal lamp colors, and controls illumination timing. By consolidating these functions into a single multi-functional control unit, the system achieves complex biometric measurement capabilities without proportionally increasing overall system complexity.
Solution Approach 2:
The system automatically detects the type of biometric information required and self-adjusts the illumination parameters without manual intervention. The control unit autonomously determines the appropriate lamp color and timing based on the imaging conditions and biometric information type, reducing the need for complex external control mechanisms.
3Loss of time
If imaging is performed immediately after accident detection, then response time is reduced, but biometric information may be lost if imaging conditions are not optimal
Solution Approach 1:
The system performs preliminary detection of biometric information types and determines optimal illumination parameters before actual imaging occurs. By preparing the illumination conditions in advance based on detected requirements, the system ensures that when imaging is performed, the conditions are already optimized for capturing the specific biometric information, preventing data loss.
Solution Approach 2:
The system uses feedback from biometric information detection to adjust illumination parameters in real-time. The control unit continuously monitors the imaging conditions and biometric information type, then adjusts lamp color and timing accordingly, creating a closed-loop system that maintains optimal imaging conditions throughout the process.

AI summary
An illumination control device includes: an accident detection unit to detect an accident of a vehicle using a signal output from a sensor mounted on the vehicle; a lamp body control unit to command a lamp body that illuminates a vehicle interior using visible light to turn on when an accident is detected by the accident detection unit; and a lamp color changing unit to change a lamp color of the lamp body when the accident is detected by the accident detection unit.
