Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a lighting system uses light sensors to control lighting devices, then the system can automatically adjust lighting conditions, but the lighting conditions are inaccurate at locations far from the sensors
Solution Approach 1:
The patent introduces mobile communication devices as intermediary measurement points between the light sensors and the locations requiring illumination. These devices carry light sensors that can accurately measure light conditions at any position in the space, transmitting the data back to the control system to enable precise lighting adjustment at the user's location regardless of distance from the main sensors
Solution Approach 2:
The system implements a feedback mechanism where light measurements taken by mobile devices at various locations are transmitted back to the control arrangement. This feedback loop enables the system to continuously monitor actual lighting conditions at user positions and automatically adjust the lighting devices to achieve desired illumination levels, resolving the inaccuracy problem at distant locations
2Measurement precision
If users manually adjust lighting devices to achieve optimal illumination, then lighting conditions can be optimized at specific locations, but this defeats the purpose of an intelligent lighting system
Solution Approach 1:
The patent enables the lighting system to serve itself by automatically detecting light conditions at user locations through mobile devices and autonomously adjusting the lighting output. The system no longer requires manual user intervention to optimize lighting, as it self-regulates based on real-time measurements transmitted from mobile devices, maintaining intelligence while improving ease of operation
3Extent of automation
If the lighting system controls lighting devices based on sensor data, then the system operates autonomously, but it cannot deliver optimal light conditions at locations far from sensors
Solution Approach 1:
The patent makes the lighting system universal by enabling it to serve multiple locations simultaneously through the mobile device network. The control arrangement can receive measurements from multiple mobile devices at different positions and autonomously adjust lighting devices to deliver optimal conditions to all locations, not just those near the original sensors, thereby enhancing adaptability while maintaining autonomous operation
