Solution Overview

Problem

Existing machine tools that attach a measurement tool to a spindle for workpiece dimension measurement face communication interference due to splatter and fluid deposition on the transceiver module, leading to obstructed communication between the measurement tool and the transceiver.

Innovation Solution

A machine tool design featuring a tool magazine with a shutter between the working and storage regions, allowing the shutter to close during workpiece machining to prevent splatter and open during measurement, along with a communication module in the storage region for wireless communication with the measurement tool's transceiver, ensuring unobstructed communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the transceiver module is attached to the ceiling of the splash guard to enable wireless communication, then communication between the measurement tool and transceiver module is established, but splatter of chips and fluid deposits on the transceiver module obstructing communication

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidsplatter deposition
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The transceiver module is extracted from the splash guard ceiling and relocated to the tool magazine, separating it from the harmful machining environment. This allows the communication function to be maintained while eliminating direct exposure to chips and fluid splatter that would obstruct communication.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The shutter acts as an intermediary element that selectively controls access to the tool magazine. It allows the transceiver module to remain in the storage region while enabling communication during measurement operations and preventing splatter intrusion during machining operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the shutter is closed during workpiece machining to protect from splatter, then protection from chips and fluid is improved, but communication between measurement tool and communication module is obstructed

Engineering Contradiction:
Improvesplatter protectionVSAvoidcommunication reliability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The shutter is made dynamic by controlling its opening and closing states based on operational mode. It remains closed during machining to protect against splatter and opens during measurement operations to enable communication, allowing the system to adapt its protective function according to real-time needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control unit preliminarily determines the operational state (machining or measurement) and adjusts the shutter position in advance. This ensures that the shutter is already in the correct position (open or closed) before the actual operation begins, preventing communication obstruction or splatter intrusion.

Inventive Principle:
Principle #10Preliminary action

3Object-affected harmful factors

If additional protective systems are added to prevent splatter deposition on the transceiver module, then protection from harmful factors is improved, but device complexity increases

Engineering Contradiction:
Improvesplatter protectionVSAvoidsystem complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The shutter, originally designed for a single function of separating the working region from the storage region, is given a dual function: it continues to provide physical separation while also serving as a protective barrier against splatter for the transceiver module. This eliminates the need for additional protective systems.

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

Solution Approach 2:

The protective function against splatter is merged with the existing shutter mechanism. Instead of adding a separate protective system, the solution combines the separation function and protection function into a single integrated component, reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)
