Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the lighting area is increased to cover the motion area, then the imaging quality is improved, but the power consumption is increased
Solution Approach 1:
The patent implements dynamic adjustment of the lighting module's beam diffusion angle to match the motion area. The lighting area is not fixed but changes according to the detected motion scope, allowing the system to provide sufficient illumination for image quality while avoiding unnecessary power consumption when the motion area is small.
Solution Approach 2:
The system changes the lighting parameter (beam diffusion angle) based on the detected motion area. By adjusting this parameter dynamically, the lighting module can adapt its coverage area to match the actual imaging requirements, optimizing the balance between image quality and power consumption.
2Use of energy by moving object
If the lighting area is reduced to save power, then the power consumption is decreased, but the image extraction quality is deteriorated
Solution Approach 1:
The system uses feedback from the motion detection function to continuously monitor the motion area and adjust the lighting module's beam diffusion angle accordingly. This closed-loop control ensures that the lighting area always matches the actual imaging requirements, preventing both over-lighting (wasting power) and under-lighting (degrading image quality).
3Adaptability or versatility
If multiple functions are integrated into the electronic device, then the functionality is improved, but the overall volume is increased
Solution Approach 1:
The patent combines the imaging module and lighting module into an integrated structure where the lighting module is positioned adjacent to the imaging module. This merging of functions reduces the overall volume compared to having separate independent components, while still providing both imaging and auxiliary lighting capabilities.
Solution Approach 2:
The integrated module serves multiple functions: imaging, motion detection, and auxiliary lighting. By designing a universal module that performs multiple functions simultaneously, the system avoids the need for separate dedicated components for each function, thereby reducing the overall device volume.
4Adaptability or versatility
If the lighting module operates independently from the imaging module, then the operational flexibility is improved, but the operation complexity is increased
Solution Approach 1:
The lighting module automatically adjusts its beam diffusion angle based on feedback from the motion detection function without requiring manual user intervention. The system self-regulates the lighting parameters according to the detected motion area, simplifying the operation for the user while maintaining operational flexibility.
