Solution Overview
Problem
Conventional pumping devices lack a safety mechanism to prevent improper operation and do not have a pressure adjustment feature, making them unsafe and difficult to operate efficiently.
Innovation Solution
A pumping device with a pressure adjusting unit that partially releases air pressure when it reaches a predetermined value, incorporating check valves and a connecting unit to ensure safe operation and easy fluid circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressure adjusting unit is added to the pumping device, then the safety and pressure control are improved, but the device complexity increases
Solution Approach 1:
The pressure adjusting unit is designed to automatically release pressure when the predetermined pressure value is reached, without requiring external control or monitoring. The unit self-activates based on the pressure condition, eliminating the need for additional control systems or user intervention, thus improving safety while minimizing added complexity.
Solution Approach 2:
The pressure adjusting unit monitors and responds to pressure parameter changes in real-time. When the pressure reaches the predetermined threshold, the unit automatically adjusts the pressure parameter by releasing excess pressure, providing intelligent pressure control without complex external systems.
2Reliability
If the pressure adjusting unit automatically releases pressure, then the safety is improved, but the loss of energy increases due to pressure release
Solution Approach 1:
The pressure adjusting unit is pre-configured with a predetermined pressure threshold that prevents dangerous pressure accumulation before it occurs. By releasing pressure at the predetermined threshold, the system prevents the harmful effect of over-pressure conditions while minimizing energy loss by releasing only when necessary.
Solution Approach 2:
The pressure release function, which could be seen as energy loss, is converted into a safety benefit by preventing potentially dangerous over-pressure conditions. The energy released is intentionally dissipated to protect the system and users from harm, transforming what would be a harmful over-pressure situation into a controlled safety mechanism.

AI summary
A pumping device includes a barrel, a top cover mounted on an open top of the barrel, a cylinder mounted in the barrel and connected to the top cover, a piston movably mounted in the cylinder, a plurality of check valves mounted on the piston, an operation unit mounted on the top cover and connected with the piston, a connecting unit mounted in the barrel and connected between the barrel and the cylinder, and a pressure adjusting unit connected between the barrel and the top cover. Thus, when the air pressure in the receiving chamber of the barrel reaches a predetermined value, the pressure adjusting unit provides a pressure release function to partially release the air pressure in the receiving chamber of the barrel so as to ensure a safe operation of the pumping device.
