Solution Overview
Problem
In monitoring devices with infrared human detection sensors and illumination light sources, deviations between detection and illumination ranges can result in inadequate illumination, leading to unclear captured images of intruders.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the detection range and illumination range are physically aligned, then the intruder can be illuminated with appropriate light amount, but it requires much time and effort to adjust directions of beams physically
Solution Approach 1:
The patent replaces the mechanical physical alignment system with an optical/electromagnetic field-based solution. The sensor module detects the position of the intruder using electromagnetic waves, and the illumination module directs light based on this detection information, eliminating the need for manual physical adjustment of beam directions.
Solution Approach 2:
The system performs self-alignment through automatic detection and control. The sensor module automatically detects intruder position, and the control unit automatically adjusts illumination direction and intensity based on the detection results, without requiring external manual intervention for alignment.
2Reliability
If the detection range and illumination range are physically aligned, then clear captured images can be obtained, but the device complexity increases due to physical adjustment mechanisms
Solution Approach 1:
The patent eliminates mechanical adjustment mechanisms by using electronic control based on sensor detection. The control unit processes detection information and electronically adjusts the illumination module, replacing complex mechanical systems with simpler electronic control circuits.
Solution Approach 2:
The sensor module serves dual purposes: it detects both the presence of intruders and their positions for illumination control. The same detection system is used for both security monitoring and guiding the illumination module, reducing the need for separate alignment mechanisms.
3Adaptability or versatility
If the illumination range is divided into multiple zones with independent control, then appropriate illumination can be provided to detected intruders, but the device complexity increases
Solution Approach 1:
The illumination range is divided into multiple divided illumination ranges, each capable of independent control. This segmentation allows the system to selectively illuminate only the regions where intruders are detected, providing appropriate illumination while maintaining clear captured images.
Solution Approach 2:
The illumination intensity in each divided range is dynamically adjusted based on the detection results. The control unit changes the illumination intensity in real-time according to the position and characteristics of detected intruders, optimizing image clarity while reducing unnecessary illumination.
