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 lifespan and versatility.

Innovation Solution

The tool core design incorporates a laminated structure with movable components and linkages that allow for non-destructive engagement and disengagement of removable carriers, utilizing a gear mechanism to move and preload components, enabling easy replacement and securement of cutting segments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cutting segments are secured tightly to the tool core, then cutting reliability is improved, but replacement difficulty increases and may damage the core

Engineering Contradiction:

Improvecutting reliabilityVSAvoidreplacement difficulty

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The tool core is divided into modular carrier sections that can be independently removed. Each carrier holds cutting segments and can be detached as a unit from the laminated core structure, allowing replacement without affecting other carriers or the core itself.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The linkage mechanism provides dynamic movement between engaged and disengaged states. During operation, linkages maintain carriers in a secure engaged position, but during maintenance, the same linkages can be actuated to move carriers to a disengaged position for easy removal.

Inventive Principle:

Principle #15Dynamics

2Productivity

If cutting segments are firmly attached to ensure stable cutting, then cutting performance is improved, but replacement time increases and core damage risk increases

Engineering Contradiction:

Improvecutting performanceVSAvoidreplacement time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

Carriers are pre-configured with engagement features and linkages that automatically secure them to the core during assembly. This preliminary configuration ensures stable cutting performance from the start, while the modular design allows for rapid replacement without time-consuming adjustments.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

By segmenting the blade into independent carrier units, replacement time is reduced to only the duration needed to remove and install specific carriers rather than the entire blade assembly, directly addressing the time loss issue.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If the tool core structure is made complex to enable removable carriers, then carrier replaceability is improved, but manufacturing complexity increases

Engineering Contradiction:

Improvecarrier replaceabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The laminated core structure with standardized carriers and linkages serves multiple functions: it provides structural support, enables carrier attachment and detachment, and allows for easy replacement. This multi-functionality reduces the need for separate specialized components, simplifying manufacturing despite the added replaceability feature.

Inventive Principle:

Principle #6Universality (Multi-functionality)

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.
