Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a piston is used to press viscous oil in the tube body, then the oil can be filled into the oil tank, but the operator has to push the piston hard which is laborious and inconvenient
Solution Approach 1:
The invention transforms the static manual pushing action into a dynamic spring-driven action. The spring accumulates elastic potential energy when compressed and automatically releases it to drive the piston, converting manual compression effort into automatic piston movement that pushes the viscous oil into the tank without requiring continuous hard pushing by the operator.
Solution Approach 2:
The spring is pre-compressed to store elastic potential energy before the filling operation begins. This preliminary action of compressing the spring creates a reservoir of mechanical energy that is automatically released to drive the piston forward, eliminating the need for the operator to continuously apply force during the oil filling process.
2Loss of substance
If the outlet of the tube body is directly communicated with the opening of the oil tank, then oil waste and pollution are reduced, but the outlet is easy to be detached from the oil tank due to incorrect force application direction
Solution Approach 1:
The spring-driven mechanism provides dynamic force application that automatically adjusts to the connection requirements. As the spring expands, it generates a controlled pushing force on the piston that is transmitted through the tube body outlet to the oil tank opening, maintaining stable connection throughout the filling process without the detachment problems caused by incorrect manual force application.
3Device complexity
If manual pushing of the piston is used, then the device structure is simple, but the operation is laborious and inefficient
Solution Approach 1:
The invention maintains relative structural simplicity by adding only a spring component to the basic piston-tube assembly. This spring element transforms the system from manual operation to automatic operation, dramatically improving filling efficiency while keeping the overall device structure simple and easy to manufacture.
Solution Approach 2:
The spring-driven mechanism makes the device self-operating once the spring is compressed. The stored elastic energy automatically drives the piston to push the oil without requiring continuous operator intervention, making the device serve itself during the filling process and greatly enhancing productivity.

AI summary
A liquid filling device is provided, including: a barrel, a piston assembly and a force accumulating assembly. The barrel defines an axial direction and includes a liquid storage space and a through hole communicated with the liquid storage space. The piston assembly includes a piston and a push rod connected with the piston, and the piston is axially movable and is disposed in the liquid storage space. The force accumulating assembly is disposed between the barrel and the piston assembly, and when the force accumulating assembly accumulates force, the piston is driven by the force accumulating assembly to move and push a liquid in the liquid storage space. Therefore, the liquid filling device can fill the liquid automatically, which is laborsaving.
