Electromagnetic Valve Housing With Breakable Coil Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic valve systems lack a cost-effective and efficient locking system that allows for easy testing and removal of coils without damaging the components, and also facilitates quick recovery and recycling of parts.
Innovation Solution
A housing with an integrated locking system that can assume two configurations: one allowing the coil to be easily positioned and removed, and another locking the coil in place, ensuring it cannot be removed without breaking the locking system. This system is designed to be simple, inexpensive, and reliable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an integrated locking system is used to firmly assemble the coil to the housing, then the coil cannot be accidentally removed, but the coil and housing cannot be separated again once coupled together, preventing testing and verification
Solution Approach 1:
The locking system transitions from a static locked state to a dynamic unlocked state through the breaking of the fragile connection element. This allows the system to provide firm assembly during normal operation while enabling separation when needed for testing or replacement, resolving the contradiction between stability and removability.
Solution Approach 2:
The connection element changes its structural parameter from intact to broken, transforming the locking system from a restrained state (preventing removal) to an unrestrained state (allowing removal). This parameter change enables the coil to be firmly assembled during operation but separable when testing is required.
2Ease of operation
If external locking systems like snap rings are used to allow selective locking and removal of the coil, then the coil can be removed without damage, but the production cost increases due to additional materials and assembly steps
Solution Approach 1:
The locking system is merged with the housing structure itself, eliminating the need for separate external locking components like snap rings. The locking functionality is integrated into the housing through the fragile connection element, reducing material costs and simplifying the manufacturing process while maintaining coil removability capabilities.
Solution Approach 2:
The fragile connection element acts as a disposable component that is inexpensive to manufacture and replace. Instead of using costly external locking systems, a simple fragile element is used that can be broken to unlock the coil, providing a cost-effective solution for enabling coil removal without requiring expensive specialized hardware.
3Ease of manufacture
If the locking system is integrated into the housing structure, then production costs are reduced, but the coil cannot be removed without irreversibly damaging the housing or coil
Solution Approach 1:
The locking functionality is extracted from the permanent housing structure and implemented through a separate fragile connection element. This allows the locking mechanism to be integrated into the housing design while maintaining the ability to remove the coil by simply breaking the fragile element, rather than requiring damage to the housing or coil themselves. The fragile element serves as a sacrificial component that enables easy coil recovery.
