Magnetic separator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Magnetic separators in central heating systems face installation constraints due to space requirements and existing connectors are difficult to use, especially when retrofitting, leading to potential damage and leakage issues.
Innovation Solution
A magnetic separator with push-fit connectors and a release tool featuring bearing areas and a locking mechanism that allows simultaneous force application to both connectors, preventing accidental release and ensuring secure fitting and easy disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw connectors are used for connection, then the magnetic separator can be securely connected to the heating circuit, but the connectors are difficult to use and may cause damage or leakage with repeated disconnection and reconnection
Solution Approach 1:
The patent replaces the traditional screw connector mechanical system with a push-fit connector system. The push-fit connectors use a collet mechanism that grips the pipe when pushed in, eliminating the need for threading and providing easy push-to-connect and push-to-release operation while maintaining secure connections.
Solution Approach 2:
The patent introduces a release tool as an intermediary device to facilitate the release of push-fit connectors. The release tool engages with the connector mechanism and allows controlled release of the collet grip, making disconnection easier and more reliable, especially when connectors are located in difficult-to-reach positions behind the magnetic separator.
2Ease of operation
If the magnetic separator requires large vertical space for insert removal, then the insert can be easily removed for cleaning, but the device cannot be installed in locations with limited vertical clearance
Solution Approach 1:
The patent divides the magnetic separator into separable components: the main housing and the insert containing the magnet and filter element. The insert can be independently removed through the bottom of the housing, allowing cleaning without removing the entire device from the heating circuit. This segmentation enables installation in locations with limited vertical space while maintaining ease of maintenance.
3Ease of operation
If quick-release push-fit connectors are used, then repeated connection and disconnection is easier, but it is difficult to release the connectors when located behind the separator in close proximity to pipes and walls
Solution Approach 1:
The patent introduces a release tool as an intermediary device that can be inserted through the bottom of the housing to engage with the push-fit connectors. This allows the operator to release the connectors from behind the separator without needing direct access to the connector release mechanisms, solving the accessibility problem while maintaining the ease of quick-release operation.
Solution Approach 2:
The patent changes the dimension of access by providing release access from the bottom of the housing rather than from the side where connectors are located. The release tool is inserted through the bottom, allowing operation of the push-fit connectors from a different spatial dimension, making them accessible even when located behind the separator near pipes and walls.

AI summary
A magnetic separator (10) for a central heating system comprises a housing (12), a separation chamber within the housing (12), inlet and outlet ports (20, 20a) extending from the housing, the inlet and outlet ports including push- fit connectors (30) having collets surrounding the mouth of each of the inlet and outlet for releasing the connectors (30), and a release tool (44), the release tool (44) having first and second bearing areas (46, 48) for bearing against the collets of the inlet and outlet connectors (30), and a handle region (50, 52) for enabling force to be applied, via the bearing areas (46,48), to both connectors (30) simultaneously.
