Solenoid Valve Armature Intermediate Component Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of solenoid valves with precise guidance and tolerances is complex and expensive due to the requirement of high tolerance requirements for the magnet armature and armature counterpart with planar end faces, leading to high manufacturing costs and limited adjustability.
Innovation Solution
A solenoid valve design featuring an armature counterpart composed of a pole core and an intermediate component, where the intermediate component is only partially arranged in the receiving opening, allowing for a multi-part design that simplifies manufacturing and improves adjustability by creating a flatter magnetic force profile, while maintaining identical part and assembly tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the magnet armature and armature counterpart are designed with planar end faces and precise guidance, then the solenoid valve achieves reliable sealing and operation, but the manufacturing complexity and cost increase significantly due to high tolerance requirements
Solution Approach 1:
The armature counterpart is divided into two separate components: a pole core and an intermediate component. The intermediate component is inserted into the receiving opening of the magnet armature, creating a segmented structure that simplifies manufacturing while maintaining functional integrity and sealing reliability.
Solution Approach 2:
The intermediate component serves as a mediator between the magnet armature and the pole core. It is arranged in the receiving opening of the magnet armature, providing a simplified interface that reduces tolerance requirements while ensuring proper magnetic coupling and sealing.
2Ease of manufacture
If a single immersion stage design is used with constant receiving opening dimensions, then the manufacturing is simpler, but the adjustability and magnetic force profile are limited
Solution Approach 1:
The intermediate component is divided into different axial regions with varying dimensions, creating multiple immersion stages (first and second immersion stages). This segmentation allows for improved magnetic force distribution and adjustability while maintaining manufacturing simplicity through the modular structure.
Solution Approach 2:
Different regions of the intermediate component have different dimensions and properties. The first and second immersion stages have distinct axial dimensions, allowing local optimization of magnetic coupling in different regions while maintaining overall manufacturing simplicity.

Function Achieved in This Case
This design results in a cost-effective and adjustable solenoid valve with improved magnetic force characteristics, achieving better adjustability and optimized performance compared to traditional single or multiple immersion stage designs, while maintaining unchanged tolerances and using identical parts.
Implementation Method 1
The magnet armature is arranged in the area of at least one coil. If the coil is de-energized, the magnet armature is in its initial position
Implementation Method 2
The magnet armature together with the armature counterpart forms a magnetic part of the solenoid valve

AI summary
The valve (1) has a magnetic armature (2) operatively connected with a sealing element (5) for displacing the sealing element, and an armature mating part (16) engaged in a receiving opening (23) that is formed in the magnetic armature. The mating part is provided with an intermediate member (20) that is rested on a pole core (19), where only the intermediate member is arranged in the receiving opening. The mating part is fixedly arranged in the solenoid valve. The intermediate member is arranged at a distance from an inner wall (31) of the receiving opening in a radial direction.
