Solution Overview

Problem

Existing cutting tools require specific installation measures for secondary cutting tools, preventing interchangeability and necessitating complete tool replacement when secondary tools wear out, leading to high costs and limited retrofitting capabilities.

Innovation Solution

The integration of cassette-like receiving housings in the primary cutting tool's shaft, allowing for detachable and replaceable secondary cutting tools, which can be easily adapted and exchanged based on the cutting task, without altering the primary tool's structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If secondary cutting tools are non-detachably integrated into the shaft of the primary cutting tool, then the structural integrity and precision of the cutting tool is improved, but the adaptability and replaceability of secondary cutting tools deteriorates

Engineering Contradiction:
Improvestructural integrityVSAvoidreplaceability of secondary cutting tools
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The cutting tool is divided into modular components: the primary cutting tool with shaft and the detachable secondary cutting tools. The secondary cutting tools can be independently removed and replaced without affecting the primary tool's structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection between primary and secondary cutting tools is made dynamic rather than static. The secondary cutting tools can be attached or detached as needed, providing flexibility while maintaining stability during operation through secure mounting mechanisms.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If specific installation measures are taken in the cylindrical shaft to precisely integrate secondary cutting tools, then the precision and stability of secondary tool integration is improved, but the device complexity and manufacturing difficulty increases

Engineering Contradiction:
Improveprecision of secondary tool integrationVSAvoidinstallation measures in shaft
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

A universal mounting structure is provided in the shaft that can accommodate different types of secondary cutting tools through standardized interfaces, reducing the need for specific installation measures for each tool type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

A mounting mechanism or adapter serves as an intermediary between the shaft and secondary cutting tools, simplifying the integration process while maintaining precision through the standardized interface design.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Weight of moving object

If the primary cutting tool is miniaturized, then the size and weight of the cutting tool is reduced, but the structural strength and stability of the cylindrical working region deteriorates

Engineering Contradiction:
Improveweight of cutting toolVSAvoidstructural strength of working region
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The cutting tool utilizes composite material construction, combining lightweight materials with high-strength components in the critical working region, achieving weight reduction while maintaining structural strength through material optimization.

Inventive Principle:
Principle #40Composite materials
