Circular Blade Core Assembly for Replaceable Cutting Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool cores for cutting blades, such as those used in cutting stone or concrete, face challenges in efficiently replacing and securing cutting segments without damaging the core, limiting their versatility and longevity.
Innovation Solution
The tool core design incorporates movable linkages and carriers that can be non-destructively engaged and disengaged, allowing for interchangeable cutting segments and preloading mechanisms to secure components, enabling easy replacement and improved structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If cutting segments are permanently fixed to the tool core, then structural integrity is maintained, but replacement and maintenance become complex and time-consuming
Solution Approach 1:
The tool core is divided into modular components: a central core structure, removable carriers, and interchangeable cutting segments. Each carrier can be independently removed and replaced, allowing maintenance without damaging the core while preserving structural integrity through the modular connection system.
Solution Approach 2:
The connection between carriers and the tool core is made dynamic rather than static. Movable linkages and engagement mechanisms allow carriers to be securely fixed during operation for structural integrity, yet easily disengaged for replacement, transforming the fixed-permanent relationship into a controllable reversible one.
2Adaptability or versatility
If the tool core uses a fixed design, then manufacturing simplicity is maintained, but versatility and adaptability are limited
Solution Approach 1:
The tool core is designed as a universal platform that can accommodate multiple types of carriers and cutting segments through standardized engagement interfaces. The same core structure supports various configurations by simply changing the carriers, providing multi-functionality without requiring multiple specialized core designs.
Solution Approach 2:
The design employs a nested structure where carriers are positioned within the tool core perimeter, and cutting segments are mounted on carriers. This nested arrangement allows compact integration of multiple functional levels (core → carriers → segments) while maintaining ease of access and replacement at each level.
3Productivity
If cutting segments are permanently attached, then structural stability during operation is ensured, but repair time and costs increase
Solution Approach 1:
Carriers are pre-configured with cutting segments and pre-loaded onto the tool core before operation. The engagement mechanisms are designed to secure carriers firmly in position prior to use, ensuring structural stability is established in advance. This preliminary securing action allows quick replacement later without compromising operational reliability.
Solution Approach 2:
The tool core design enables self-service maintenance through its modular carrier system. Operators can independently remove worn carriers and install new ones without requiring specialized tools or complex procedures, reducing repair time and costs while maintaining structural integrity through the self-securing engagement mechanisms.

AI summary
Tool cores may have removable sections, which may be removable without damaging, cutting or severing attachment configurations for the removable sections. The removable sections may be handled simultaneously. Moving parts used to facilitate removal of the removable sections may be secured in a pre-loaded configuration.
