Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional multiple detection function LED products are used, then detection functions are provided, but the device becomes bulky and requires severe environmental conditions for installation
Solution Approach 1:
The patent combines multiple detection functions (human body detection, infrared detection, visible light detection) into a single integrated detection module that works in conjunction with the LED module. This merging of detection capabilities into one compact unit reduces the overall device volume while maintaining versatile detection functions.
Solution Approach 2:
The detection module is designed to perform multiple detection functions simultaneously - human body detection, infrared detection, and visible light detection - making it a universal module that can handle various detection needs without requiring separate dedicated devices, thereby reducing overall system volume.
2Duration of action of stationary object
If conventional multiple detection function LED products are used for long term illumination, then illumination is provided, but high temperature worsens detection accuracy
Solution Approach 1:
The patent segments the device into functionally independent modules - the LED module for illumination and the detection module for detection functions. This segmentation allows the detection module to be positioned away from the heat-generating LED module, reducing thermal interference and maintaining detection accuracy during long-term illumination operations.
Solution Approach 2:
The patent introduces an intermediary spatial arrangement where the detection module is positioned separately from the LED module, with the detection module detecting objects through the light path without being directly exposed to the heat generated by the LED module. This intermediary positioning reduces thermal interference while maintaining detection functionality.
3Adaptability or versatility
If conventional optic detection products are used, then detection is provided, but light refraction from LED affects detection accuracy
Solution Approach 1:
The patent applies local quality by providing different functional zones - the LED module emits light in specific directions for illumination, while the detection module is positioned and oriented to detect reflected light from targets. The detection module has specific detection regions that are optimized to receive reflected light while minimizing direct exposure to LED light refraction, thereby maintaining detection accuracy.
4Measurement precision
If additional independent detection system is built for multiple modes of detection and long term illumination, then detection accuracy is improved, but expense increases
Solution Approach 1:
The patent merges the LED module and detection module into a single integrated lighting device with a unified power supply and control system. This integration eliminates the need for separate independent detection systems, reducing overall system complexity and expense while maintaining accurate detection capabilities through the modular design.
