Solution Overview

Problem

Machine tools, such as sawing machines, require tool-specific process data for optimal operation, which can lead to errors if not correctly entered by operators, resulting in inefficient processing times and potential tool damage.

Innovation Solution

Incorporating detection means, such as sensors for reading tool-specific codes, into the control device of machine tools to automatically identify tools and retrieve corresponding process data specifications from external sources, eliminating the need for operator intervention and ensuring optimized operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual entry of tool-specific process data is used, then operator control is maintained, but errors occur and processing time increases

Engineering Contradiction:
Improveaccuracy of process dataVSAvoidtime for data entry
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The control device automatically retrieves and enters tool-specific process data using its communication interface and detection means, eliminating the need for manual operator input. The system serves itself by autonomously identifying the tool via code detection and fetching corresponding process parameters from external sources or memory.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical process of operator data entry is replaced by an automated electronic system. Detection means (such as optical or RFID sensors) automatically identify the tool, and the communication interface electronically retrieves process data, substituting human action with automated technological means.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If automated tool recognition is implemented, then errors are eliminated, but device complexity increases

Engineering Contradiction:
Improveaccuracy of tool identificationVSAvoidcomplexity of control system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control device's communication interface serves multiple functions: it communicates with external data sources, detects tool codes, retrieves process data, and controls the drive device. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity.

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

Solution Approach 2:

Tool-specific process data are stored externally or in a separate memory area, acting as an intermediary between the tool and the control logic. The control device simply retrieves and applies this data rather than containing all control knowledge internally, reducing system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
