Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual commissioning is performed by operators, then the lighting system can be configured and controlled, but the process becomes complex and labor-intensive
Solution Approach 1:
The lighting system performs automatic commissioning without human operators. The controller autonomously discovers light sources, determines their positions, sets intensity levels, and creates navigation paths through self-service algorithms that process light intensity measurements and spatial relationships
Solution Approach 2:
The patent replaces manual mechanical commissioning operations with an automated optical-electronic system. The controller uses light intensity measurements from sensors to automatically map the spatial arrangement of light sources and generate navigation paths, substituting human operators with an automated detection and control system
2Reliability
If manual commissioning is performed, then light sources can be configured, but errors may occur and energy savings are negatively impacted
Solution Approach 1:
The system uses feedback from light intensity measurements to verify and adjust the commissioning process. The controller continuously measures light intensity at different positions, compares measurements against expected values, and automatically adjusts light source intensity levels to achieve optimal illumination and energy efficiency
Solution Approach 2:
The patent replaces error-prone manual commissioning with an automated optical measurement and control system that objectively determines light source positions and intensity settings based on measured light intensity data, eliminating human errors in configuration
3Productivity
If automatic commissioning is implemented, then complexity and time are reduced, but iterative measurement and path creation are required
Solution Approach 1:
The system performs preliminary actions by pre-defining intensity level values for light sources and pre-establishing measurement positions before actual commissioning. The controller prepares the navigation path algorithm and intensity setting parameters in advance, enabling faster execution of the commissioning process
Solution Approach 2:
The commissioning process uses periodic iterative measurements at defined positions P0, P1, P2, etc., where the controller systematically cycles through measuring light intensity at each position, adjusting intensity levels, and updating the navigation path in periodic steps until commissioning is complete
