Linear Module Magnetic Dustproof Strip Without Friction Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing low dust linear modules generate dust and fine particles due to friction between magnetic members and dustproof belts or strips, affecting the operation and working environment standards.
Innovation Solution
The solution involves positioning magnetic members at the slide seat end portions with defined magnetic attraction gaps between the magnetic members and the slide seat and cover, preventing friction between the magnetic members and the dustproof strip, ensuring the magnetic members and dustproof strip are kept in a gap without contact, thus avoiding dust generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic members are used to magnetically attract and hold the dustproof belt, then dustproof effect is improved, but friction between magnetic members and dustproof belt generates dust
Solution Approach 1:
A magnetic attraction section is introduced as an intermediary between the magnetic members and the dustproof belt. This magnetic attraction section is magnetically attracted to the magnetic members, which indirectly holds the dustproof belt in position without direct contact between the magnetic members and the belt, thereby eliminating friction and dust generation while maintaining the dustproof effect.
Solution Approach 2:
The patent replaces the direct mechanical contact system (magnetic members directly contacting the dustproof belt) with a magnetic field-based system. The magnetic attraction section mediates the magnetic force transmission, allowing the magnetic members to hold the dustproof belt through magnetic attraction rather than mechanical contact, thus eliminating friction-induced dust generation.
2Reliability
If magnetic layers are coated on rail and slide seat, then dustproof effect is improved, but processing cost increases
Solution Approach 1:
The patent segments the magnetic functionality into separate components: magnetic members (which can be standard magnetic components) and a magnetic attraction section (a relatively simple component). This segmentation avoids the need to coat entire rail and slide seat surfaces with magnetic layers, thereby reducing processing complexity and cost while maintaining effective dustproof coverage.
Solution Approach 2:
Instead of applying magnetic layers uniformly across large surfaces (rail and slide seat), the patent concentrates magnetic functionality at specific locations where magnetic members are positioned. The magnetic attraction section is equipped with a magnetic attraction area that provides localized magnetic attraction, achieving effective dustproof effect only where needed, thus reducing material and processing costs.

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 effectively prevents the generation of dust and fine particles, allowing the linear module to operate normally and maintain the working environment standards by eliminating friction between magnetic members and the dustproof strip.
Implementation Method 1
two magnetic members (50) are disposed on a side of the slide seat (31) facing the dustproof strip (40)... the two magnetic members (50) magnetically attract the magnetic attraction section (43)

AI summary
A low dust linear module includes a rail unit, a slide seat unit, a dustproof strip and two magnetic members. The two magnetic members are disposed at the two slide seat end portions of the slide seat, the first magnetic attraction gap is defined between the magnetic attraction area and a corresponding one of the magnetic members, and the second magnetic attraction gap is defined between the magnetic attraction area and the slide seat cover. When the dustproof strip passes through and are magnetically attracted by the magnetic members, a gap will appear between the magnetic members and the slide seat and the slide seat cover, so that the magnetic members and the dustproof strip are kept in a gap without friction, so as to avoid the generation of dust due to friction, so that the linear module can operate normally and maintain the standard of the working environment.
