Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional presence detection methods are used to control lighting devices, then the system can detect whether a person is present, but the detection accuracy of the person's position is low
Solution Approach 1:
The detection space is divided into multiple detection regions, and a sensor detects presence or absence of a person in each region. The control device specifies irradiation state data based on which detection region contains the person, enabling precise position detection through spatial segmentation without requiring complex detection equipment.
Solution Approach 2:
The patent transitions from simple presence/absence detection to spatial position detection by dividing the detection space into multiple regions. This dimensional approach allows the system to identify not just whether a person is present, but also their specific location within the space, improving detection accuracy while maintaining relatively simple system complexity.
2Adaptability or versatility
If the lighting system uses basic presence detection, then the system is simple to operate, but it cannot provide situation-specific control of lighting conditions
Solution Approach 1:
The control device automatically specifies irradiation state data based on the detection region where the person is present, without requiring manual intervention. The system self-adjusts lighting conditions according to the detected person's position, providing situation-specific control while maintaining ease of operation through automated decision-making.
Solution Approach 2:
The sensor continuously detects the person's position in different detection regions, and the control device uses this feedback information to automatically adjust the irradiation state. This closed-loop feedback mechanism enables the lighting system to adapt to different situations based on real-time detection data while operating automatically without user complexity.
3Measurement precision
If the system divides the detection space into multiple regions for better position detection, then detection accuracy improves, but the system complexity increases
Solution Approach 1:
The detection space is segmented into multiple detection regions, allowing the system to determine which region contains the person for more accurate position detection. This segmentation approach improves measurement precision by providing spatial information while keeping the implementation relatively simple through regional division rather than continuous coordinate detection.

AI summary
A lighting system 10 includes a lighting device configured to adjust an irradiation state including at least one of an irradiation direction or a focal length and irradiate an irradiation region with light, a control device 500 configured to control the irradiation state of the lighting device, and a sensor 102 configured to detect presence or absence of a person in each of a plurality of detection regions. The control device specifies, based on a detection result of the sensor and a position detection model with a manned region learned in advance as a region where a person is present among the plurality of detection regions, irradiation state data specifying the irradiation state corresponding to the position detection model and controls the irradiation state to the irradiation region based on the irradiation state data.
