Engineering Contradiction Analysis
1Measurement precision
If multiple devices (laser screen forming unit and image capturing unit) are used for gas leak detection, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent combines the laser screen forming function and image capturing function into a single integrated device. The image capturing unit is positioned to capture images of the laser screen formed by the laser beam, eliminating the need for separate laser screen forming units and reducing overall system complexity while maintaining detection accuracy
Solution Approach 2:
The image capturing unit serves multiple functions: it captures images of the laser screen to detect tracer movement, and can also directly detect gas flow patterns. This multi-functionality reduces the need for additional specialized devices while maintaining comprehensive detection capability
