Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional method of draining oil through the oil-exporting hole and using an adjustable oil-importing tube is used, then the oil can be changed, but the process becomes complex and requires extra containers
Solution Approach 1:
The patent combines the draining and refueling operations into a single integrated process. The oil-importing tube serves dual purposes: it both refuels the transmission and drains excess oil through its lower end, eliminating the need for separate draining containers and simplifying the overall procedure.
Solution Approach 2:
The oil-importing tube is designed with multi-functionality, serving as both a refueling conduit and a draining mechanism. By extending the tube's lower end below the transmission oil level, it automatically drains excess oil while maintaining its primary refueling function, reducing the need for additional specialized components.
2Quantity of substance
If the oil-importing tube is used to drain extra oil, then the oil can be controlled, but the refueling device has to be removed causing oil leakage and waste
Solution Approach 1:
The patent implements preliminary action by pre-configuring the oil-importing tube's lower end to extend below the transmission oil level before refueling begins. This anticipatory positioning ensures that as soon as oil is infused and the level rises, excess oil automatically drains through the tube without requiring removal or adjustment, preventing leakage and waste.
Solution Approach 2:
The extended lower end of the oil-importing tube acts as an intermediary mechanism between the refueling process and excess oil removal. It provides a controlled pathway for oil to drain back into the transmission or designated container, mediating the oil level control function and preventing uncontrolled leakage during the refueling operation.
3Productivity
If the oil is drained quickly, then the process is faster, but the oil sprinkles on the ground or users causing safety hazards and pollution
Solution Approach 1:
The patent introduces an intermediary containment system through the oil-importing tube structure and associated receiving components. This intermediary mechanism captures and channels the draining oil through controlled pathways, preventing it from spraying or sprinkling onto the ground or users while maintaining efficient draining speed through the structured flow path.
Solution Approach 2:
The patent converts the potentially harmful fast draining process into a beneficial controlled operation. By designing the oil-importing tube system with proper flow management and containment features, the rapid oil removal is transformed from a hazard into an efficient process that prevents spillage while maintaining high productivity.

Function Achieved in This Case
The device enables efficient and safe oil changing by minimizing spills and waste, maintaining oil quality, and simplifying the process, reducing environmental impact and user effort.
Implementation Method 1
the pump member is movable in the second passage... the piston rod moves the pump member between the first position and the second position in the second passage
Implementation Method 2
a pump member and a check valve, the first passage connected between the main channel and the second passage, the check valve mounted in the second passage
Implementation Method 3
the backflow valve inserted into the through hole of the base body, the backflow valve selectively closing or unclosing the backflow passage
Implementation Method 4
the elastomer has a recovery force which pushes the thin portion toward the backflow passage
