Electromagnetic Valve Spring Contact Point Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic valves lack the ability to individually adjust the force-displacement characteristic of their spring elements and achieve targeted, stabilizing alignment of the armature with respect to the pole core, leading to suboptimal performance in terms of valve opening and closing.
Innovation Solution
The design incorporates a spring element that forms multiple spaced-apart contact points with the end faces, allowing for a single bearing point on one end face and enabling the use of different spring elements with varying force-displacement characteristics, which can be arranged radially and axially to generate transverse forces for centering and guiding the magnet armature, along with locking mechanisms to secure the spring element in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single contact point configuration is used for the spring element, then the structure is simple, but the force-displacement characteristic cannot be individually adjusted and stabilizing alignment is not achieved
Solution Approach 1:
The spring element is divided to form multiple spaced-apart contact points with the end faces, creating multiple bearing points that enable individual adjustment of the force-displacement characteristic while maintaining structural simplicity
Solution Approach 2:
Different contact points of the spring element are positioned at specific locations on the end faces to generate targeted transverse force components, providing localized stabilizing alignment functionality where needed
2Adaptability or versatility
If multiple spring elements are provided with different force-displacement characteristics, then the force characteristic can be optimized, but the device complexity increases
Solution Approach 1:
The spring element is segmented into multiple contact points that can be independently positioned, allowing different sections of a single spring element to provide different force characteristics without requiring multiple separate spring elements
Solution Approach 2:
A single spring element is designed to perform multiple functions: providing the primary spring force, generating transverse force components for alignment, and enabling adjustable force-displacement characteristics through its multiple contact points configuration
3Stability of the object's composition
If the spring element is designed to form multiple contact points, then stabilizing alignment of the armature is achieved, but the manufacturing complexity increases
Solution Approach 1:
The spring element and end faces are designed with asymmetric contact point positions that generate targeted transverse force components, achieving stabilizing alignment functionality through the asymmetric configuration rather than complex symmetric structures
Solution Approach 2:
The multiple contact points are positioned to distribute forces evenly and create a stable equilibrium position for the armature, achieving alignment through force balance rather than complex mechanical guides
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for precise adjustment of the force-displacement characteristic, stabilizes the magnet armature, and ensures maximum valve lift with minimal air gap, enhancing the overall operational efficiency of the valve.
Implementation Method 1
an elastically deformable spring element is arranged between an end face of the magnet core facing the magnet armature
Implementation Method 2
when the magnet armature is attracted by the magnet core, it detaches from the valve opening and thereby opens it

AI summary
The valve (1) has a magnetic core (3) firmly arranged in a casing (2), and a magnetic armature (4) actuating a valve element (6). A resilient deformable spring element (13) i.e. disk spring (14), is arranged between a core front surface (11) and an armature front surface (12) of the core, where the core front surface turns toward the core and the armature front surface turns toward the armature. The spring element and/or front surfaces are formed such that the spring element with one of the front surfaces forms two bearing positions, which are spaced from each other.
