Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and storage requirements of maintaining multiple variants of reducing sleeves for machining tools, which vary in diameter and coolant supply capabilities, lead to increased manufacturing and storage costs in manufacturing environments.
Innovation Solution
A multifunctional reducing sleeve with a modular system that includes a sealing unit and a safety unit, allowing the same sleeve to be used universally across different applications by coupling these units to the sleeve via a multifunctional interface, reducing the need for multiple sleeves and lowering storage costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple variants of reducing sleeves are maintained for different machining tools and applications, then adaptability and versatility are improved, but storage costs and manufacturing costs increase
Solution Approach 1:
The reducing sleeve is designed with a multifunctional interface that can perform multiple functions: providing pull-out safety geometry, sealing coolant supply channels, and coupling to tool holders. This single universal reducing sleeve replaces the need for multiple specialized variants, thereby reducing storage costs while maintaining adaptability across different machining applications
Solution Approach 2:
The reducing sleeve is divided into functional modules: the main reducing sleeve body, optional sealing units for coolant channels, and safety units for pull-out protection. These modular components can be selectively combined or omitted based on specific application requirements, allowing one base design to serve multiple purposes without requiring separate reducing sleeves for each function
2Adaptability or versatility
If multiple variants of reducing sleeves are maintained for different machining tools and applications, then adaptability and versatility are improved, but manufacturing costs increase
Solution Approach 1:
By designing a universal reducing sleeve with integrated coolant supply channels and a multifunctional interface, the invention enables a single manufacturing process to produce sleeves suitable for various applications. This eliminates the need to manufacture multiple specialized variants, thereby reducing manufacturing costs while maintaining versatility
Solution Approach 2:
The invention merges previously separate functions (coolant supply, pull-out safety, tool holder coupling) into a single integrated reducing sleeve design. This consolidation allows for streamlined manufacturing processes and reduced tooling requirements, thereby lowering manufacturing costs while providing versatile functionality
3Adaptability or versatility
If reducing sleeves with integrated coolant supply channels are used, then coolant supply capability is improved, but complexity of the reducing sleeve design increases
Solution Approach 1:
The reducing sleeve is designed with integrated coolant supply channels as a standard feature rather than an optional add-on, allowing the same basic design to serve both cooling needs and structural functions. This universal approach adds coolant capability without requiring separate complex designs for cooled vs. non-cooled applications
Solution Approach 2:
The coolant supply channels are strategically positioned within the reducing sleeve structure, utilizing existing geometric features and interfaces. The sealing units are selectively applied only where coolant channels require sealing, rather than sealing the entire sleeve. This localized approach adds coolant functionality while minimizing overall design complexity
