Solution Overview

Problem

Current textile machines require highly qualified personnel and are inefficient in identifying and addressing production deviations, as they rely on manual visual inspections and expert knowledge, leading to increased costs and reduced productivity due to the need for extensive downtime during error analysis.

Innovation Solution

Implementing a textile machine with a central control unit that automatically initiates checks on functional resources during production interruptions, allowing for targeted checks based on detected deviations, and providing clear, text-based results to operators, enabling semi-skilled personnel to perform maintenance and reducing downtime.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual visual inspections and expert knowledge are used to identify production deviations, then accurate error detection is achieved, but highly qualified personnel are required and productivity decreases due to extensive downtime

Engineering Contradiction:
Improveerror detection accuracyVSAvoidproduction productivity
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The textile machine performs self-diagnosis by automatically initiating checks of functional resources when production interruptions occur. The control unit autonomously determines deviations from desired production processes and triggers targeted checks without requiring manual inspection, enabling the system to monitor and diagnose itself

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual visual inspections by highly qualified personnel are replaced by an automated electronic control system. The control unit uses sensors and automated checking processes to detect production deviations and identify error causes, substituting human expert analysis with automated electronic monitoring and evaluation

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

2Measurement precision

If manual visual inspections are performed at each workstation, then error causes can be identified, but the process becomes time-consuming and expensive

Engineering Contradiction:
Improveerror cause identificationVSAvoidmaintenance time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary automated checks of functional resources immediately when production interruptions occur. By proactively initiating diagnostic processes at the moment of interruption rather than waiting for manual inspection, the system identifies error causes quickly and enables immediate maintenance action

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The textile machine autonomously performs self-diagnosis by automatically checking functional resources and determining error causes without requiring manual intervention. The control unit independently evaluates production deviations and initiates targeted checks, eliminating the need for time-consuming manual inspections

Inventive Principle:
Principle #25Self-service

3Productivity

If automated checks are implemented, then productivity is improved and downtime is reduced, but the system complexity increases

Engineering Contradiction:
Improveproduction productivityVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Instead of implementing comprehensive automated monitoring of all functional resources continuously, the system applies automated checks locally and selectively only to relevant functional resources when production interruptions occur. This targeted approach maintains productivity benefits while minimizing the complexity burden of continuous system-wide monitoring

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system performs automated checks partially rather than completely - only checking functional resources that are relevant to the detected production deviation. This selective checking approach provides sufficient error diagnosis capability without requiring complex monitoring of every possible system parameter

Inventive Principle:
Principle #16Partial or excessive action

4Loss of time

If targeted checks based on detected deviations are performed, then error analysis time is reduced, but the system requires intelligent automation capabilities

Engineering Contradiction:
Improveerror analysis timeVSAvoidautomation intelligence
Core Design Contradiction:
Loss of timeVSExtent of automation

Solution Approach 1:

The control unit continuously monitors production parameters and provides feedback when deviations from desired production processes are detected. This feedback triggers automated targeted checks of specific functional resources, creating a closed-loop system where production monitoring automatically initiates diagnostic actions based on real-time conditions

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts its diagnostic approach based on the detected production deviation. Rather than performing fixed predetermined checks, the control unit adapts the checking process to target specific functional resources relevant to the current deviation, optimizing error analysis time while managing automation complexity

Inventive Principle:
Principle #15Dynamics
