Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate solar light sensors are provided for the air condition system and auto light system, then each system can be controlled according to its specific conditions, but costs increase and device complexity increases
Solution Approach 1:
The patent applies universality by enabling a single illumination sensor to perform multiple functions: it detects light for both the air condition system (to control temperature compensation) and the auto light system (to control lamp operation). This multi-functional approach eliminates the need for separate sensors while maintaining the ability to control each system according to its specific requirements, thereby reducing device complexity without sacrificing control accuracy
2Reliability
If separate solar light sensors are provided for the air condition system and auto light system, then each system can be controlled according to its specific conditions, but costs increase
Solution Approach 1:
The patent reduces manufacturing costs by utilizing one illumination sensor for both the air condition system and auto light system, eliminating the need to manufacture and install two separate sensors. The single sensor is configured to provide detection signals that both systems can utilize according to their respective control requirements, achieving cost savings without compromising the reliability or control accuracy of either system
3Device complexity
If a single illumination sensor is used for both air condition and auto light systems, then costs are reduced and device complexity is reduced, but the sensor must handle multiple control conditions
Solution Approach 1:
The illumination sensor is designed with multi-functionality to handle diverse control conditions: it detects light intensity for temperature compensation control in the air condition system and simultaneously detects light intensity for lamp operation control in the auto light system. The sensor's output signal is processed by respective control units that apply different control logic appropriate to each system's requirements, thereby maintaining control condition flexibility while using a single sensor
Solution Approach 2:
The patent applies segmentation by separating the control processing functions: the single illumination sensor provides detection signals that are independently processed by the air condition controller and the auto light controller. Each controller applies its own control logic and thresholds appropriate to its system, allowing the single sensor to serve multiple purposes without compromising the adaptability or control flexibility of either system
