Solution Overview

Problem

Existing measuring systems for machine tools require complex and space-consuming setups with multiple pneumatic and electrical lines, posing risks of collision and damage, and complicating the installation and connection processes.

Innovation Solution

A multipurpose interface socket provides a mechanical, electrical/optical, and pneumatic fluid connection between the machine tool's controller and the measuring device, with preloaded pins for tolerance compensation and sealed contact points to reduce errors and contamination, allowing for easy installation and operation without additional external lines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple pneumatic and electrical lines are used to connect the measuring system to the machine tool, then the measuring system can provide sealing air, control laser light passage, clean the tool, and supply power and operating signals, but the installation effort and complexity of connection increase considerably

Engineering Contradiction:
Improvefunctional completenessVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate pneumatic and electrical connection functions into a single integrated connection interface. The measuring system establishes one unified connection to the machine tool that simultaneously provides sealing air through pneumatic lines, controls laser light passage, cleans the tool, and supplies power and operating signals through electrical lines, thereby reducing installation effort while maintaining functional completeness

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connection interface is designed as a universal multi-functional unit that handles both pneumatic and electrical connections through a single interface structure. This multi-functional connector serves multiple purposes: providing sealing air, controlling laser passage, enabling tool cleaning, and transmitting power and signals, eliminating the need for separate dedicated connections for each function

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

2Ease of operation

If the measuring system is moved to a measuring position within the working area via swivel or linear unit, then measurement can be performed on tools in the working area, but the risk of collision with moving tools and exposure to damage from chips or tools increases

Engineering Contradiction:
Improvemeasurement accessibilityVSAvoidcollision risk
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a transparent protective cover as an intermediary element between the measuring system and the working environment. This cover allows the measuring system to be positioned within the working area for measurement accessibility while protecting it from chips and tools. The transparency of the cover maintains laser beam transmission for measurement functionality while providing physical protection

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If pneumatic lines are provided for the measuring system, then sealing air and tool cleaning functions can be achieved, but the laying and assembly effort of pneumatic lines increases

Engineering Contradiction:
Improvepneumatic functionalityVSAvoidassembly effort
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent merges pneumatic line connections with electrical connections into a single integrated connection interface. The pneumatic lines for sealing air and tool cleaning are bundled together with electrical lines and connected through one unified interface structure, significantly reducing the laying and assembly effort compared to separate pneumatic connections

Inventive Principle:
Principle #5Merging (Combining)
