Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the welding gun is built in the arc sensor, then the structure is integrated and the tracking effect is good, but the maintenance and replacement of the welding gun becomes inconvenient
Solution Approach 1:
The arc sensor is divided into separate functional modules: the sensor body housing containing the arc sensing mechanism, and the welding gun as a detachable component. This segmentation allows the welding gun to be easily removed and replaced without disassembling the entire sensor, while the sensor body maintains its integrated tracking functionality.
Solution Approach 2:
The welding gun is extracted from the built-in configuration and positioned externally, connected to the arc sensor through a detachable connection mechanism. This extraction enables independent maintenance and replacement of the welding gun while preserving the arc sensor's tracking capabilities.
2Reliability
If the motor drives the welding gun to perform conical movement, then the tracking effect is good, but the structure becomes complicated, the volume increases, and the vibration becomes large
Solution Approach 1:
A connecting rod is introduced as an intermediary component between the motor and the welding gun. The connecting rod converts the motor's rotational motion into the required conical scanning motion of the welding gun, simplifying the overall structure compared to direct complex mechanisms while reducing vibration through the intermediate connection.
3Ease of operation
If the welding gun needs to be maintained or replaced, then accessibility is required, but the built-in configuration causes inconvenient maintenance and replacement
Solution Approach 1:
The welding gun is taken out from the built-in configuration and positioned externally with detachable connections, enabling easy access for maintenance and replacement operations while maintaining operational accessibility during normal use.
