Modular Brush-Like Grinding Stone with Detachable Linear Member Aggregates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing brush-like grinding stones with large diameters require frequent replacement due to broken bundles and adhesive wear, leading to increased costs and resource wastage, and are inflexible in adapting to different workpieces without needing to prepare multiple brushes.
Innovation Solution
A brush-like grinding stone with detachable linear member aggregates, where each bundle is fixed to a linear member holder and attached to the brush holder via holding holes, allowing for easy addition, removal, or replacement of aggregates as needed, reducing the need for full stone replacement and enabling adaptation to various workpieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the brush-like grinding stone uses a large diameter to polish wide area, then the polishing coverage is improved, but the cost increases and the stone needs frequent replacement when bundles break
Solution Approach 1:
The grinding stone is divided into multiple independent linear member aggregates that can be individually replaced. Each aggregate consists of linear members bundled together and fixed to the brush holder, allowing selective replacement of only the worn or broken aggregates rather than the entire grinding stone structure.
Solution Approach 2:
The invention enables recovery and reuse of the brush holder and intact linear member aggregates. When some bundles wear out or break, only those specific aggregates are replaced while the brush holder and other functional aggregates are retained and reused, reducing waste and cost.
2Ease of manufacture
If the bundles of linear members are fixed with adhesive, then the attachment is simple, but the entire stone must be replaced when adhesive wears or bundles break
Solution Approach 1:
The grinding stone structure is segmented into modular linear member aggregates that are independently attachable and detachable from the brush holder. This segmentation allows individual aggregates to be replaced without affecting other parts, combining simple attachment with easy repair capability.
Solution Approach 2:
The attachment system transitions from a static permanent bond (adhesive only) to a dynamic system where linear member aggregates can be attached and detached as needed. This enables flexible replacement of worn bundles while maintaining simple attachment procedures.
3Adaptability or versatility
If multiple brush-like grinding stones are prepared for different workpieces, then the adaptability is improved, but the cost and resource consumption increase
Solution Approach 1:
The brush holder is designed as a universal component that can accommodate different types and numbers of linear member aggregates. A single brush holder can be used with various aggregate configurations to polish different workpiece types, eliminating the need for multiple specialized grinding stones and reducing resource consumption.

AI summary
A brush-like grinding stone (3) in a polishing brush (1) includes a brush holder (6) and a linear member aggregate (7) detachably held in the brush holder (6). The linear member aggregate (7) includes a large number of bundles (51) of the linear members (50) obtained by hardening aggregated yarn of inorganic filaments impregnated with a resin, and a brush holder (70) holding ends of the bundles (51). A linear member holder (70) in the linear member aggregate (7) is detachably attached to each of a plurality of holding holes (68) that is open in one side in an axial line direction L. In a case where any of the linear member aggregates has a failure, such as breakage, only the failed linear member aggregate needs to be replaced. Thus, it is not necessary to discard the entire brush-like grinding stone. Consequently, the polishing cost can be reduced.
