Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual triggering and stopping is used for the electric oil pump, then the device complexity is reduced, but the productivity and reliability deteriorate due to inefficiencies and high failure rates
Solution Approach 1:
The pump system performs self-control through the pressure-sensitive diaphragm mechanism that automatically detects pressure changes in the fluid passage and triggers the motor accordingly, eliminating the need for external manual operation or complex control systems
Solution Approach 2:
The pressure-sensitive diaphragm provides continuous feedback on the pressure conditions in the fluid passage, automatically adjusting the pump operation based on real-time pressure changes to maintain optimal performance
2Reliability
If the pump operates continuously without pressure-based control, then the productivity is maintained, but the reliability deteriorates due to high failure rates from unnecessary operation
Solution Approach 1:
The pressure-sensitive diaphragm continuously monitors pressure in the fluid passage and provides feedback to the control mechanism, enabling the pump to automatically start when pressure drops (indicating oil needs dispensing) and stop when pressure rises (indicating sufficient oil level), thereby improving reliability while maintaining productivity
3Reliability
If a simple switch mechanism is used without buffer protection, then the manufacturing cost is reduced, but the reliability deteriorates due to mechanical wear and failure from rapid movements
Solution Approach 1:
The buffer member is positioned to provide cushioning protection to the switch mechanism before rapid movements can cause damage, absorbing shock and reducing mechanical wear to extend the durability of the control components

Function Achieved in This Case
The pump operates smoothly and efficiently, reducing failure rates and manufacturing costs by automating the pumping process and ensuring consistent fluid flow control.
Implementation Method 1
capable of pressing the pressing member when the pressure in the fluid passage is above an upper threshold and releasing the pressing of the pressing member when the pressure in the fluid passage is below a lower threshold
Implementation Method 2
The spring pushes the detent ball against the movable element, keeping the detent ball in a position against the movable element

AI summary
An electric oil pump includes a base portion, a pump portion, a power supply, a mechanical switch and a pressure trigger. The base portion has a fluid passage. The pump portion is disposed on the base portion. The power supply is provided with an electric power to the pump portion. The mechanical switch is electrically connected the pump portion and the power supply, and has a pressing member. When the pressing member is not pressed, the mechanical switch is in a conductive state, and when the pressing member is pressed, the mechanical switch is in a non-conductive state. The pressure trigger is located between the mechanical switch and the fluid passage, capable of pressing the pressing member when the pressure in the fluid passage is above an upper threshold and releasing the pressing of the pressing member when the pressure in the fluid passage is below a lower threshold.
