Sanding Pad Transpirant Hook and Loop Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanding tools require precise alignment of abrasive parts with pads, which is cumbersome due to varying models and hole configurations, limiting the use of abrasive components and complicating dust extraction.
Innovation Solution
The use of transpirant tear-off materials like Velcro with a knitted surface structure and mushroom-shaped or hook-and-loop connecting elements on the pad surface, eliminating the need for hole alignment and enhancing dust extraction without obstructing airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tear-off materials are used for engagement, then adhesion during sanding is achieved, but precise alignment of holes between pad and abrasive part is required which complicates operation
Solution Approach 1:
The engagement surface of the pad is made entirely adhesive using tear-off material, eliminating the need for hole alignment. This universal adhesive surface can engage with any abrasive part regardless of hole configuration, making the system universally compatible while maintaining reliable adhesion during sanding operations
2Object-generated harmful factors
If through holes are provided in the pad for dust extraction, then dust elimination is promoted, but alignment with abrasive part holes is required which increases device complexity
Solution Approach 1:
The patent extracts the alignment requirement from the dust extraction function. Instead of requiring holes in both pad and abrasive part to align, the invention uses the adhesive engagement surface to maintain relative position, allowing the abrasive part's holes to function for dust extraction without needing to align with pad holes
Solution Approach 2:
The adhesive engagement surface serves multiple functions: it provides secure engagement during sanding, maintains relative positioning for dust extraction, and eliminates alignment requirements. This multi-functional approach simplifies the overall device complexity while maintaining effective dust extraction
3Adaptability or versatility
If multiple pad models with varying hole configurations are used, then compatibility with different abrasive parts is achieved, but ease of operation deteriorates due to alignment requirements
Solution Approach 1:
The pad is designed with a universal adhesive engagement surface that can engage with any abrasive part model regardless of hole configuration. This eliminates the need for multiple specialized pad models while maintaining compatibility and versatility across different abrasive parts
