Solenoid Valve Lock Portion for Easy Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solenoid valves are difficult to disassemble and maintain, making it challenging to change flow properties and perform internal maintenance, which leads to the need for replacing the entire valve when debris jams or different flow rates are required.
Innovation Solution
A solenoid valve design with a lock portion that can be elastically deformed to allow easy disassembly and reassembly of the plunger and valve body, enabling various flow rate properties without replacing the entire valve, and facilitating internal maintenance by using a bobbin with integral extended portions as the lock mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the yoke and fixed cover are fixed by compression and the other end of the plunger is covered by the protruding cover, then the solenoid valve structure is stable and secure, but disassembly becomes difficult making it impossible to replace the plunger and valve body
Solution Approach 1:
The invention divides the solenoid valve into separable components: the casing remains fixed while the bobbin is designed with an extractable structure. The plunger and valve body can be removed by extracting the bobbin through the through-hole, while the casing maintains its stable compressed structure. This segmentation allows easy replacement of internal components without disassembling the entire valve.
Solution Approach 2:
The through-hole in the casing acts as an intermediary access path. It allows the bobbin to be inserted and extracted from the casing without disassembling the compressed yoke and fixed cover structure. This intermediary feature enables component replacement while maintaining overall structural stability.
2Adaptability or versatility
If the entire solenoid valve must be replaced to change flow amount properties, then flow rate customization is achieved, but manufacturing costs increase and the number of models increases
Solution Approach 1:
The invention separates the flow control function (valve body) from the actuation mechanism (bobbin and plunger). Different valve bodies with various flow characteristics can be inserted into the same casing by simply replacing the bobbin assembly. This allows multiple flow rate configurations using a single standardized casing, reducing manufacturing costs and model variety.
Solution Approach 2:
The casing is designed as a universal component that can accommodate different bobbin and valve body combinations. The standardized through-hole and mounting structure allow the same casing to support multiple flow rate configurations, making the solenoid valve system multi-functional and adaptable to different flow requirements without increasing the number of models.
3Reliability
If the entire solenoid valve must be replaced when debris is jammed, then reliability is maintained, but maintenance cost and time increase
Solution Approach 1:
The invention enables segmentation of the valve into serviceable components. When debris jams occur, only the valve body and plunger need to be removed through the through-hole for cleaning or replacement, while the casing and bobbin can remain in place. This dramatically reduces maintenance time compared to replacing the entire valve, while maintaining reliability through easy access to critical components.
Solution Approach 2:
The design allows users to perform self-maintenance by simply extracting the bobbin through the through-hole to access and clean the valve body. This self-service capability eliminates the need for professional service or complete valve replacement, reducing both maintenance time and costs while preserving valve reliability.

AI summary
In a solenoid valve, a bobbin and a solenoid coil are accommodated in a casing. A rod-shaped plunger is slidably inserted into the bobbin. A core provided with a flow port through which a fluid flows is disposed on one side of the casing. A valve body is attached to one end opposing the flow port of the plunger. In a non-operating period during which a solenoid coil is in a non-energized state, the valve body moves away from the flow port due to the biasing force applied by the biasing portion and another end of the plunger protrudes outward from the casing through the through hole, abuts against lock portions disposed outside of the casing, and is thereby locked. The lock portions can be elastically deformed by an external force such that separation of the plunger and the valve body from the casing is allowed.
