Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation with infrared thermometers or temperature sensors is used, then the detection process is simple to implement, but the detection efficiency is low and cannot detect multiple elements simultaneously
Solution Approach 1:
The patent uses an infrared camera to capture thermal radiation images of multiple PCB elements simultaneously, creating a visual copy of the temperature distribution. This allows parallel detection of multiple elements without manual intervention, dramatically improving detection efficiency while maintaining relative system simplicity
Solution Approach 2:
The patent introduces a movable bearing support that can dynamically reposition the infrared camera to different locations on the PCB. This dynamic positioning capability enables the system to detect multiple elements sequentially or simultaneously at different positions, enhancing productivity without requiring a complex multi-camera static system
2Measurement precision
If direct sensor coupling to elements is used, then the temperature detection is accurate, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent replaces direct mechanical sensor coupling with non-contact infrared detection. The infrared camera detects thermal radiation from elements without physical contact, maintaining measurement precision while eliminating the complex operation of coupling sensors to each element
Solution Approach 2:
The infrared camera automatically detects and measures temperatures of elements based on their emitted thermal radiation without requiring manual intervention for sensor placement or calibration. The system performs self-service temperature detection, greatly simplifying operation while maintaining accuracy
3Adaptability or versatility
If multiple temperature detectors are used to detect multiple elements, then the detection coverage is improved, but the device complexity and cost increase
Solution Approach 1:
The patent uses a single infrared camera that can detect multiple elements simultaneously by capturing thermal images of the entire PCB or specific regions. This universal detector performs the function of multiple individual sensors, improving detection coverage without increasing the number of detectors
Solution Approach 2:
The movable bearing support enables a single infrared camera to dynamically access different positions on the PCB, effectively expanding its detection coverage to multiple elements. This dynamic positioning allows one detector to replace multiple fixed detectors, reducing device complexity while maintaining versatility
