Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of cameras is performed by user operation, then the user can adjust camera positions, but image capturing ranges may overlap or blind spots may occur, reducing surveillance accuracy
Solution Approach 1:
The system performs automatic camera adjustment using the imaging unit to capture images and the processing unit to calculate optimal camera parameters. The cameras self-adjust based on calculated positions without requiring manual user operation, thereby eliminating overlapping and blind spots while maintaining high surveillance accuracy
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated optical-mechanical system. The imaging unit captures images, the processing unit calculates optimal positions, and the driving unit automatically adjusts camera positions based on calculated parameters, substituting human manual operation with an automated control system
2Ease of operation
If manual adjustment of cameras is performed, then the user can set camera positions, but it is difficult to eliminate overlapping or blind spots, making the process troublesome
Solution Approach 1:
The system automatically performs the entire camera setting process including image capture, parameter calculation, and physical adjustment. This self-service mechanism eliminates the troublesome manual adjustment process while significantly reducing the time required to achieve optimal camera positioning without overlapping or blind spots
Solution Approach 2:
The imaging unit first captures images of the surveillance area before adjustment, and the processing unit calculates optimal camera parameters in advance. This preliminary action allows the system to pre-determine the best camera positions, making the subsequent adjustment process quick and efficient rather than requiring time-consuming trial and error
