Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional abrasives face issues with dust and residue accumulation, leading to clogging and reduced efficiency in surface finishing processes, while non-continuous support abrasives have lower processing speeds and rigidity.
Innovation Solution
An open mesh woven fabric is impregnated with a binder, followed by the application of abrasive granules and drying, creating a flexible and permeable abrasive material that minimizes clogging and maintains high surface finish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional abrasives with continuous support are used, then high superficial planarity and finishing are achieved, but dust and process residues accumulate leading to clogging
Solution Approach 1:
The patent employs an open mesh support structure with inherent porosity that allows dust and process residues to pass through during abrasion operations. The mesh configuration creates channels for debris ejection, preventing accumulation and clogging while maintaining continuous support for high finishing quality
Solution Approach 2:
The continuous support is segmented into an open mesh structure with interconnected voids and channels. This segmentation creates multiple pathways for dust ejection while maintaining structural integrity and support continuity, resolving the contradiction between smooth finishing and dust accumulation
2Object-generated harmful factors
If abrasives on non-continuous support are used, then dust removal is improved, but processing speed decreases due to compliance and rigidity issues
Solution Approach 1:
The open mesh support provides a porous structure that facilitates dust ejection while maintaining structural rigidity. The interconnected framework prevents excessive compliance issues seen in non-woven products, thereby maintaining high processing speeds without sacrificing dust removal capability
Solution Approach 2:
The patent combines the open mesh support with abrasive granules and binder to create a composite structure. This composite material integrates the dust-removal benefits of non-continuous support with the structural rigidity and processing speed of continuous support systems
3Manufacturing precision
If closed mesh woven fabric with sponge structure is used, then optimum finish is achieved, but dust accumulation and clogging occur during use
Solution Approach 1:
Instead of using a closed mesh structure that traps dust, the patent inverts the approach by employing an open mesh structure. This inversion allows dust to be ejected through the mesh openings rather than trapped, maintaining high finish quality without clogging
Solution Approach 2:
The open mesh support acts as a porous material with controlled void spaces that facilitate dust ejection. The porous structure maintains surface contact for high finishing while providing escape routes for dust particles, preventing accumulation
