Solution Overview

Problem

Existing tool and workpiece holders require interface adapters to accommodate different machine tool standards, leading to reduced workspace and increased misalignment errors.

Innovation Solution

A tool or workpiece holder with a coupling section that can interact with both SK50 and HSK80 standards without the need for adapters, utilizing an adapter ring that can be fixed in two orientations and a modified tool interface with specific sections for each standard.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If interface adapters are used to accommodate different machine tool standards, then compatibility with different standards is improved, but workspace is reduced and misalignment errors increase

Engineering Contradiction:
Improvecompatibility with different standardsVSAvoidworkspace
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The coupling section is designed with a universal interface that can directly accommodate both SK50 and HSK80 standards without requiring separate adapters. The coupling section includes a first section for SK50 and a second section for HSK80, allowing the same tool holder to interface with different machine tool standards directly, thereby eliminating the need for interface adapters and preserving workspace.

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

2Adaptability or versatility

If interface adapters are used to accommodate different machine tool standards, then compatibility with different standards is improved, but misalignment errors increase

Engineering Contradiction:
Improvecompatibility with different standardsVSAvoidmisalignment error
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The coupling section merges the SK50 and HSK80 interface sections into a single integrated component. This direct integration eliminates the additional interface between the adapter and tool holder that causes misalignment errors. The first section and second section of the coupling section are precisely positioned to ensure accurate alignment with their respective machine tool standards without introducing additional error sources.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If interface adapters are used to accommodate different machine tool standards, then compatibility with different standards is improved, but device complexity increases

Engineering Contradiction:
Improvecompatibility with different standardsVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention extracts and eliminates the interface adapter component from the system by integrating both SK50 and HSK80 interface capabilities directly into the coupling section of the tool holder. This removes the need for separate adapter components, thereby reducing device complexity while maintaining compatibility with different standards.

Inventive Principle:
Principle #2Taking out (Extraction)
