Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual oil injection methods (oil injecting bottle or syringe) are used, then the device is simple and easy to carry, but the output quantity of oil is not easy to control and the quality of injecting oil is not very well
Solution Approach 1:
The patent replaces the manual mechanical pressing system with an electric pump system controlled by a control switch. The pump motor drives the pump to automatically inject oil, replacing the need for manual squeezing or syringe pressing, thereby achieving precise control over oil quantity while maintaining portability through the compact electric system.
Solution Approach 2:
The patent introduces a control switch that allows operators to adjust and control the oil injection parameters (quantity, speed, and timing). This parameter control mechanism enables precise adjustment of oil output without requiring complex manual dexterity, resolving the contradiction between ease of operation and device complexity.
2Measurement precision
If a pump controlled by a control switch is used for automatic oil injection, then the quantity of oil is easy to control and the injecting quality is improved, but the device becomes more complex
Solution Approach 1:
The patent incorporates a feedback hole that allows brake oil to feedback into the container automatically. This self-service mechanism eliminates the need for complex manual feedback systems or additional sensors, as the feedback hole passively returns excess oil to the container, maintaining measurement precision while minimizing added complexity.
Solution Approach 2:
The feedback hole system enables the recovery and reuse of brake oil that has been injected and then returned. This recovering mechanism improves oil quantity control precision by allowing operators to monitor and adjust the injection process, while the simple hole structure avoids adding significant device complexity.
3Reliability
If manual pressing is used to inject oil, then the device structure is simple, but the quality of injecting oil deteriorates
Solution Approach 1:
The patent replaces the unreliable manual pressing mechanism with a controlled electric pump system. The pump provides consistent, reliable oil injection pressure and flow rate, eliminating the variability and poor quality associated with manual pressing, while the compact pump design keeps the overall structure manageable.

Function Achieved in This Case
The automatic oil injector provides precise control over oil quantity, simplifies the maintenance process, and ensures high-quality oil injection while being compact and easy to carry, addressing the limitations of manual oil injection methods.
Implementation Method 1
a pump (5), having an inlet port (51) and an outlet port (52), the end of the suction pipe exposed externally to the cover (2) and the container (1) is fluidly connected with the inlet port (51) of the pump (5)
Implementation Method 2
the oil injecting pipe is fluidly communicated with a check valve for preventing the oil from being flowed back and preventing the air inflow from being kept in of the oil injecting pipe in vacuum condition while stopping injecting oil
Implementation Method 3
one end of the suction pipe is accommodated in the container so as to contact an inner bottom surface of the container and the other end of the suction pipe is exposed externally to the cover and the container
