Solution Overview

Problem

Existing brush manufacturing machines experience unplanned downtime due to unforeseen operational issues, necessitating lengthy troubleshooting and reducing overall efficiency.

Innovation Solution

Implement a control unit in the brush manufacturing machine that autonomously monitors process parameters and wear levels using sensors, allowing it to adjust actuator settings to maintain a defined target state, thereby preventing failures and reducing downtime.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If preventive maintenance is carried out according to a defined schedule, then machine reliability is improved, but productivity deteriorates due to planned downtime

Engineering Contradiction:
Improvemachine reliabilityVSAvoidproductivity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The machine monitors its own operational parameters and wear levels autonomously through integrated sensors and control units, enabling self-diagnosis and self-reporting of maintenance needs without external intervention or scheduled shutdowns

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously collects data from sensors monitoring operational parameters and wear levels, feeds this information to the control unit, which then provides feedback to operators or automatically adjusts operations to maintain optimal performance and predict maintenance timing

Inventive Principle:
Principle #23Feedback

2Reliability

If unplanned downtime occurs due to operational issues, then reliability deteriorates, but time for troubleshooting and repair increases

Engineering Contradiction:
Improvetechnical availabilityVSAvoiddowntime
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary monitoring of wear levels and operational parameters to detect potential failures before they occur, allowing maintenance to be scheduled at convenient times rather than responding to unexpected breakdowns

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual inspection and reactive maintenance with automated sensor-based monitoring and electronic analysis, substituting mechanical troubleshooting processes with electronic data collection and automated diagnostics

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

3Reliability

If wear parts are monitored and replaced proactively, then reliability is improved, but device complexity increases due to additional sensors and control systems

Engineering Contradiction:
Improvetechnical availabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control unit serves multiple functions: it controls the stuffing machine operation, processes sensor data from multiple wear parts, analyzes operational parameters, generates maintenance alerts, and communicates with external systems, replacing what would otherwise require separate dedicated systems for each function

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

Solution Approach 2:

The patent combines the monitoring functions for multiple wear parts (bundle divider, tamping tool, brush holder) into a single integrated control unit that processes all sensor data centrally, rather than using separate monitoring systems for each component

Inventive Principle:
Principle #5Merging (Combining)
