Filter Element Butt Joint Mechanism for One-Handed Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing filter element mounting process requires significant manual effort and coordination to apply insertion and screwing forces, making it difficult for non-specialized personnel to mount the filter element correctly, as the sealing ring generates resistance and can lead to movement of the main machine during installation.
Innovation Solution
A filter element butt joint mechanism featuring a fixed base with a columnar mounting cavity, a butt joint base, a limit sliding-clamping mechanism, and a screw transmission mechanism, which allows for a butt joint between insertion pipes and plug-holes to be formed by screwing the housing, eliminating the need for a large axial force and enabling one-handed mounting, with features like an elastic cushion and magnetic attraction to secure the joint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sealing ring is used to seal the junction during filter element mounting, then sealing effectiveness is improved, but the insertion force required increases significantly making the operation difficult
Solution Approach 1:
A mounting auxiliary device is introduced as an intermediary tool between the operator and the filter element. This device includes a clamping mechanism that grips the housing and a screwing mechanism that applies rotational force, mediating the mounting process to reduce direct manual effort while maintaining effective sealing ring compression
Solution Approach 2:
The mounting auxiliary device enables the filter element to be mounted with reduced manual intervention. The clamping mechanism automatically grips the housing, and the screwing mechanism self-generates the necessary rotational force through manual cranking, making the system more self-sufficient during the mounting process
2Ease of manufacture
If a large insertion force is applied during mounting, then the separation ring can be inserted into the connector, but the main machine moves causing operational difficulty
Solution Approach 1:
The clamping mechanism applies a counter-clamping force to the housing that counteracts the insertion force. As the screwing mechanism applies rotational force to drive the separation ring into the connector, the clamping mechanism simultaneously applies an opposing force to prevent the main machine from moving, maintaining system stability
Solution Approach 2:
The mounting auxiliary device acts as an intermediary that decouples the insertion force from the main machine. The device absorbs and manages the large insertion forces through its clamping and screwing mechanisms, preventing these forces from directly moving the main machine while still achieving successful insertion
3Device complexity
If manual mounting is performed without auxiliary devices, then device complexity is reduced, but productivity decreases due to difficult operation
Solution Approach 1:
The mounting auxiliary device is designed to be manually operated without requiring additional power sources or complex control systems. The operator cranks the handle to simultaneously engage the clamping and screwing mechanisms, making the system self-sufficient and easy to use while significantly improving mounting efficiency
Solution Approach 2:
The mounting auxiliary device combines multiple functions into a single integrated tool: the clamping mechanism, screwing mechanism, and handle are merged into one device that performs both clamping and screwing operations simultaneously, improving productivity without proportionally increasing complexity
