Solution Overview
Problem
Existing material collection devices for machine tools, such as sanding machines, face issues with filter protection, durability, dimensional stability, and efficient dust removal, leading to clogging and reduced operating convenience.
Innovation Solution
A material collection device with a filter protective cover and a support element that securely clamps the filter element, featuring a dust-repellent coating, air outlet openings, and a design that allows for easy cleaning and efficient air flow, preventing dust sticking and filter deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the filter element is used without a support element for clamping, then the device complexity is reduced, but the filter element lacks dimensional stability and protection
Solution Approach 1:
The patent employs a support element with a clamp structure that provides rigid support to the filter element, preventing deformation while maintaining a relatively simple overall structure. The support element acts as a structural reinforcement that preserves the filter element's shape during operation.
2Device complexity
If the filter element is used without a filter protective cover, then the device complexity is reduced, but the filter element lacks protection and is prone to damage
Solution Approach 1:
The filter protective cover serves as a protective shell that shields the filter element from external damage, dust contamination, and mechanical stress. This simple cover structure significantly enhances the reliability and lifespan of the filter element without adding complex mechanisms.
3Ease of operation
If the filter element is not securely clamped, then the ease of operation is improved, but the filter element deforms and filtering efficiency decreases
Solution Approach 1:
The support element features a segmented clamp structure with multiple clamping points that can independently secure different portions of the filter element. This segmentation allows for distributed clamping force that prevents deformation while maintaining ease of installation through a modular design.
Solution Approach 2:
The clamp structure applies clamping force at multiple discrete points rather than uniform pressure, providing sufficient local pressure to prevent filter element deformation at critical areas while avoiding excessive overall force that could damage the filter material.
4Reliability
If air outlet openings are not provided in the filter protective cover, then the protection of the filter element is improved, but dust accumulation and clogging occur
Solution Approach 1:
The filter protective cover incorporates air outlet openings at specific locations where they are most effective for dust removal while maintaining protection in other areas. The openings are strategically positioned to allow air and dust escape paths without compromising the overall protective function of the cover.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced protection and durability of the filter element, prevents clogging, ensures efficient filtering, and improves user convenience by allowing easy cleaning and maintaining a high level of operational efficiency.
Implementation Method 1
The filter element (14) is provided to filter the material, which is preferably mechanically separated and/or removed from a workpiece by the machine tool (12), from an air flow guided through the filter element (14)
Implementation Method 2
The filter element (14) comprises a dust-repellent coating (30) on at least one inner side
