Solution Overview

Problem

Existing brush manufacturing machines experience unplanned downtimes due to unforeseen operational issues, despite preventive maintenance, requiring significant downtime for identifying and correcting the causes.

Innovation Solution

A brush manufacturing machine with a control unit that autonomously detects input variables such as wear and process parameters, triggering targeted responses to maintain the machine in a defined target state, reducing or eliminating unplanned downtimes through machine learning and actuator control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If preventive maintenance measures are carried out according to a defined plan, then machine reliability is improved, but unplanned downtimes still occur due to unforeseen operational issues

Engineering Contradiction:
Improvemachine reliabilityVSAvoidunplanned downtimes
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The control unit performs preliminary actions by continuously monitoring process parameters and detecting undesired states before they lead to machine failures. This allows the system to take corrective actions in advance, preventing unplanned downtimes before they occur.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements continuous feedback by monitoring process parameters and comparing them against defined states. When deviations are detected, the control unit automatically triggers corrective actions, creating a closed-loop control system that prevents failures before they occur.

Inventive Principle:
Principle #23Feedback

2Productivity

If the machine operates continuously without intervention, then productivity is improved, but undetected undesired states can lead to machine failures

Engineering Contradiction:
Improveproduction efficiencyVSAvoidmachine stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The machine performs self-service through automated monitoring and control. The control unit independently detects undesired states and triggers corrective actions without human intervention, allowing continuous operation while maintaining reliability through self-diagnosis and self-correction capabilities.

Inventive Principle:
Principle #25Self-service

3Reliability

If manual monitoring and correction of machine states is performed, then machine stability is improved, but significant time is lost for identifying and correcting causes

Engineering Contradiction:
Improvemachine stabilityVSAvoiddowntime for cause identification and correction
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical monitoring and correction with an automated control system. The control unit electronically monitors process parameters and automatically triggers corrective actions, substituting human operators with an automated system that responds instantaneously without the time delays associated with manual intervention.

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

4Speed

If automated control systems are implemented, then response time to undesired states is improved, but device complexity increases

Engineering Contradiction:
Improveresponse speedVSAvoidcontrol system complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The control unit serves multiple functions: monitoring process parameters, detecting undesired states, determining corrective actions, and triggering responses. This multi-functional approach consolidates what could be separate complex systems into a single integrated control unit, achieving fast response times while managing complexity through functional integration.

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