Film-Pouch Grease Gun for Leak-Free Speed Reducer Refilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grease guns have low workability, tend to leak, and are costly due to the need for a bellows-type container with a gas barrier layer to prevent grease seepage, and the process of refilling and replacing grease in speed reducers is inefficient and time-consuming.
Innovation Solution
A grease gun with a pouch container made of film material, sealed with a spout, containing a lubricant composition with specific viscosity and base oil proportions, which can be easily connected to a speed reducer without transferring the grease, reducing leakage and simplifying the refilling process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bellows-type container with a gas barrier layer is used to prevent grease seepage, then grease storage reliability is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent uses a flexible pouch made of film material to contain the grease instead of a complex bellows-type container with gas barrier layers. The pouch is simply sealed and inserted into the cylindrical member, providing grease containment without requiring complex multi-layer structures or expansion mechanisms.
Solution Approach 2:
The patent employs a simple, inexpensive pouch that can be easily replaced when empty, rather than investing in a complex, expensive bellows-type container. The pouch is designed as a disposable or easily replaceable component, reducing overall system cost and complexity.
2Ease of operation
If a filling type grease gun is used, then grease can be injected into speed reducer, but workability is low and grease remains in the gun
Solution Approach 1:
The patent extracts the grease from the gun by using a push member that forces all grease out of the pouch and through the connecting member into the speed reducer. The gun is designed to completely empty the pouch, eliminating the problem of residual grease remaining in the gun after use.
Solution Approach 2:
The push member automatically pushes all grease from the pouch through the connecting member and into the speed reducer without requiring manual intervention to extract remaining grease. The system self-completes the grease transfer process, ensuring complete emptying of the pouch.
3Duration of action of stationary object
If grease is stored in bellows-type container for long periods, then storage capacity is provided, but seepage prevention requires expensive barrier layers
Solution Approach 1:
The patent uses a simple film material pouch for long-term grease storage instead of expensive bellows-type containers with barrier layers. The pouch is sealed to prevent seepage during storage and can be stored for extended periods without requiring complex protective structures.
Solution Approach 2:
The patent employs an inexpensive sealed pouch that can be manufactured at low cost and used for long-term grease storage. The simplicity of the pouch structure dramatically reduces manufacturing costs compared to bellows-type containers with multiple barrier layers.
