Solution Overview

Problem

Conventional holding sleeves for rotary cutting tool holders have a single fixed method for discharging cooling liquids, limiting their versatility across different types of rotary cutting tools.

Innovation Solution

The holding sleeve features a sleeve body with multiple clamping slits and outlet segments that can be selectively blocked to change the discharge path of cooling liquids, allowing for different discharging ways to accommodate various rotary cutting tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single fixed discharge method is used in the holding sleeve, then the structure is simple, but the adaptability to different rotary cutting tools is poor

Engineering Contradiction:

Improveadaptability to different rotary cutting toolsVSAvoidstructure complexity of holding sleeve

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The holding sleeve is divided into multiple outlet segments (first outlet segment with first outlet holes, second outlet segment with second outlet holes, third outlet segment with third outlet holes) that can be independently blocked or opened. Each segment provides a different discharge path for cooling liquid, allowing the structure to adapt to various rotary cutting tool requirements without increasing overall structural complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The holding sleeve incorporates movable blocking elements that can selectively block different outlet segments. This dynamic capability allows the discharge path of cooling liquid to be changed based on the specific rotary cutting tool being used, transforming a static single-discharge structure into a multi-functional adaptive structure.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple outlet segments are added to provide different discharge paths, then the versatility is improved, but the device complexity increases

Engineering Contradiction:

Improveversatility of cooling liquid dischargeVSAvoidcomplexity of outlet structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple outlet segments and their associated blocking mechanisms are integrated into a single holding sleeve body. The first, second, and third outlet segments are combined with their respective blocking elements within one unified structure, allowing versatile cooling liquid discharge without requiring separate components or assemblies.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The holding sleeve is designed as a universal component that can accommodate different rotary cutting tools through its multiple configurable outlet segments. By incorporating blocking elements that can selectively activate different discharge paths, the single holding sleeve structure performs multiple functions that would otherwise require different specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A holding sleeve has a sleeve body having multiple clamping slits, and an outlet portion. The clamping slits are defined longitudinally and radially in the outer surface, are arranged at even angular intervals and communicate with the rotary cutting tool hole. Each clamping slit has a first end and a lateral branch. The lateral branch extends laterally from the first end of the clamping slit and communicates with the clamping slit. The outlet portion is formed in the outer end of the sleeve body and communicates with the lateral branches of the clamping slits.
