Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual updates of lighting maps are used when lamps are repositioned or new lamps are added, then the system can maintain position-based control, but the process is inefficient and inconvenient requiring repeated manual intervention
Solution Approach 1:
The lamp system performs self-positioning by automatically detecting its location and the locations of other lamps using antenna arrays and signal processing, eliminating the need for manual mapping updates. The system serves itself by autonomously maintaining position information without user intervention.
Solution Approach 2:
The system uses antenna arrays to continuously detect signal information from external devices and other lamps, processing this feedback to automatically determine and update position data. This closed-loop feedback mechanism enables real-time position tracking without manual intervention.
2Extent of automation
If antenna arrays with angle of incidence measurement are implemented, then automatic position determination is enabled, but the device complexity increases
Solution Approach 1:
The antenna arrays serve multiple functions: they detect the positions of other lamps, identify external devices, and enable automatic positioning. By making the system multi-functional, the patent justifies the added complexity through enhanced capability and automation.
Solution Approach 2:
The patent replaces manual mechanical mapping updates with an electromagnetic field-based automatic detection system using antenna arrays. This substitution of mechanical/manual processes with electromagnetic sensing enables automation while accepting the inherent complexity of the sensing system.
3Productivity
If position-based control of lighting is implemented, then energy savings and user comfort are improved, but the system requires continuous updates when lamps are repositioned
Solution Approach 1:
The system automatically detects position changes and updates lighting control parameters without requiring user intervention. When lamps are repositioned, the antenna arrays detect the new positions and the system autonomously adjusts the lighting map, maintaining energy efficiency while simplifying user operation.
Solution Approach 2:
The lighting control system is made dynamic by continuously monitoring position information through antenna arrays and automatically adapting the lighting map in real-time. This dynamic adjustment ensures energy efficiency is maintained regardless of lamp positions, eliminating the need for manual reconfiguration.
