Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional abrasive tools for surface treatment of marbles, stones, and ceramic materials often cause damage and 'burns' due to their stiffness and rapid wear, especially when encountering uneven surfaces, leading to reduced operational performance and shorter tool life.
Innovation Solution
An abrasive tool with side-by-side arranged plate-like working elements embedded in an elastomeric body, which are removably anchored to a support member, providing a flexible and durable surface treatment solution that avoids damage and maintains performance over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a cylindrical abrasive body with compact and stiff structure is used, then the tool provides sufficient structural strength, but it causes damage and burns to the surface being treated due to its stiffness when encountering uneven surfaces
Solution Approach 1:
The patent changes the material parameter from rigid resin-based material to elastomeric material, which fundamentally alters the mechanical behavior. The elastomeric material provides the necessary structural strength while simultaneously offering flexibility to adapt to surface unevenness, thereby eliminating the harmful burning effect caused by rigid materials.
Solution Approach 2:
The patent uses composite construction by embedding abrasive particles within an elastomeric matrix. This composite structure combines the hardness of abrasive particles with the flexibility of elastomeric material, achieving both structural integrity and surface-adaptive behavior that prevents damage to the workpiece surface.
2Strength
If resin-based abrasive filaments are used, then the tool can be made with sufficient strength, but the filaments undergo permanent deformation over time due to operative movement direction, causing rapid deterioration of operative capacity
Solution Approach 1:
The patent changes the material parameter from resin-based to elastomeric, which fundamentally alters the deformation characteristics. Elastomeric materials exhibit elastic deformation that recovers after operation, preventing permanent set and maintaining consistent operative capacity throughout the tool's service life.
Solution Approach 2:
The elastomeric material provides dynamic adaptability, allowing the abrasive elements to flex and recover during operation. This dynamic behavior enables the tool to maintain its working geometry and abrasive capacity consistency, unlike rigid materials that suffer permanent deformation in the direction of operative movement.
3Stability of the object's composition
If a rigid abrasive tool structure is used, then the tool maintains its shape, but it wears out rapidly when encountering unevenness on the surfaces to be worked
Solution Approach 1:
The patent changes the material parameter from rigid to elastomeric, which fundamentally alters the wear mechanism. The elastomeric material can flex and deform elastically when encountering surface unevenness, distributing stress more evenly and preventing concentrated wear points that would cause rapid deterioration of rigid tools.
Solution Approach 2:
The elastomeric material provides dynamic stress distribution, allowing the tool to adapt its shape temporarily when encountering uneven surfaces. This dynamic response prevents stress concentration and localized wear, thereby extending the tool's operational life while maintaining shape stability during normal operation.
Applied Scientific Principles
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 tool effectively prevents surface damage and 'burns' by flexing on uneven surfaces and maintains constant performance due to its elastic properties, resulting in longer tool life and reduced sediment production.
