Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If industrial towline or flexible cable is used to take power for the shifting fork, then power can be supplied to the moving part, but the cable wears over time and needs regular replacement
Solution Approach 1:
The patent extracts the cable from the moving part (shifting fork) and relocates it to the stationary guide rail. The power is now taken through a stationary conductive component in the guide rail that contacts with a conductive component on the extension arm, eliminating the need for cables to move with the shifting fork.
Solution Approach 2:
The patent introduces an intermediary conductive structure - the guide rail with embedded conductive components - that mediates the power transmission between the stationary power source and the moving extension arm, eliminating direct cable connection to the moving part.
2Reliability
If towline or cable is installed on the shifting fork to take power, then power can be delivered to the actuating mechanism, but installation and maintenance become complex
Solution Approach 1:
The patent extracts the cable from the moving part (shifting fork) and relocates it to the stationary guide rail. The power is now taken through a stationary conductive component in the guide rail that contacts with a conductive component on the extension arm, eliminating the need for cables to move with the shifting fork.
Solution Approach 2:
The guide rail structure automatically provides power through its stationary conductive components that naturally contact with the conductive component on the extension arm during normal operation, eliminating the need for separate installation and maintenance of flexible cables.
3Reliability
If special towlines or cables are purchased for power taking, then power can be supplied to the moving part, but the cost increases
Solution Approach 1:
The guide rail structure is designed to serve dual functions: providing mechanical guidance for the extension arm and simultaneously providing electrical power through embedded conductive components. This eliminates the need for separate specialized power cables.
Solution Approach 2:
The patent replaces expensive specialized flexible power cables with a simpler, more durable stationary conductive structure in the guide rail that can be easily manufactured and replaced if needed.
