Solution Overview
Problem
The limited installation space in switching devices restricts the use of multiple additional modules for A-releases or U-releases, limiting the functionality and flexibility of magnetic releases in switching devices.
Innovation Solution
Integrating the U-release function into a magnetic release by adjusting the total magnetic field generated by superimposed permanent magnets, allowing the magnetic release to switch between E, A, and U release functions, enabling flexible use of the installation space and combining different release functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple additional modules (A-release or U-release) are installed to expand functionality, then the versatility and adaptability of the switching device is improved, but the device complexity and installation space requirements increase
Solution Approach 1:
The patent combines the E-release, A-release, and U-release functions into a single magnetic release device. The permanent magnet assembly can be configured to provide different magnetic field strengths that enable the device to perform electronically controlled release, shunt release, or undervoltage release functions respectively, eliminating the need for separate modules
Solution Approach 2:
The magnetic release device is designed with universal functionality to perform multiple release operations. By adjusting the magnetic field strength of the permanent magnet assembly, the same device can serve as an E-release, A-release, or U-release, making it a multi-functional component that replaces multiple specialized modules
2Adaptability or versatility
If multiple additional modules are installed to provide different release functions, then the adaptability is improved, but the installation space requirements worsen
Solution Approach 1:
The patent merges multiple release functions into a single compact magnetic release device. The permanent magnet assembly with adjustable magnetic field strength allows one device to replace what would traditionally require separate E-release, A-release, and U-release modules, significantly reducing the installation space required
Solution Approach 2:
The magnetic release device provides universal functionality for different release operations within a single compact unit. By configuring the permanent magnet assembly to provide appropriate magnetic field strengths, the device can perform E-release, A-release, or U-release functions, eliminating the need for multiple space-consuming modules

AI summary
The invention relates to a controllable magnetic release (12) for a switching device with a movable armature (16) for releasing a locking chain of the switching device, a spring (20) which exerts a force on the armature to press it into a position for releasing the locking chain of the switching device, an electrical coil (22) which, when energized in a manner dependent on a release function, generates a magnetic field acting on the armature which either moves the armature into the release position or holds the armature in a latching position against the pressure of the spring, a first and a second permanent magnet (18, 19) whose magnetic fields are oppositely polarized, and an adjusting device (21) for adjusting the total magnetic field generated by superimposing the magnetic fields of the first and second permanent magnets to a first or a second strength, wherein the total magnetic field with the first strength is dimensioned such thatto hold the armature in the locked position against the force of the spring, and the total magnetic field with the second strength is such that it alone is not sufficient to hold the armature in the locked position against the force of the spring.
