Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If emergency lighting system integrates sensor modules with control unit, then intelligence and adaptability of the system is improved, but device complexity increases
Solution Approach 1:
The patent integrates the sensor module, control unit, emergency lighting means, and battery into a single luminaire housing. This merging of previously separate components into one unified device achieves the intelligent adaptability through sensor-based control while managing complexity through integrated design rather than multiple separate devices.
Solution Approach 2:
The luminaire is designed to perform multiple functions: regular illumination, emergency lighting, and environmental sensing. The control unit responds to sensor readings by adapting emergency lighting operation, making the system universally applicable for both normal and emergency conditions with automated environmental adaptation.
2Measurement precision
If sensor module is exposed to ambiance, then measurement precision of sensor readings is improved, but device complexity increases due to integration requirements
Solution Approach 1:
The sensor module is physically integrated into the luminaire housing with its sensing elements exposed to the ambient environment through strategically positioned openings or transparent portions of the housing. This integration allows direct environmental exposure for accurate sensing while consolidating multiple components into one device.
Solution Approach 2:
The luminaire housing is designed with specific local characteristics: certain portions are transparent or have openings to allow sensor exposure to ambient light and environmental conditions, while other portions provide protection and structural support. This local differentiation enables both accurate sensing and device protection.
