Solution Overview

Problem

Current methods for monitoring wear in mobile machine components, such as track links, often result in premature replacement or delayed maintenance, leading to unnecessary costs and downtime, and require cumbersome sensor installations that disrupt machine operation.

Innovation Solution

A track link with a sensing device embedded in its cavity, secured by a containment mechanism, which detects wear parameters and transmits signals to a communication device for real-time monitoring and maintenance scheduling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If wear monitoring is performed using external sensors and cabling, then wear data can be collected, but the machine operation is disrupted and costs increase

Engineering Contradiction:
Improvewear data accuracyVSAvoidmachine operation continuity
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The sensing device is integrated directly into the track link structure, merging the monitoring function with the structural component. This eliminates the need for external sensors and cabling, allowing continuous machine operation without disruption while maintaining accurate wear measurement capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The track link monitors its own wear condition through the embedded sensing device, eliminating the need for external monitoring systems. The component serves both its mechanical function and self-diagnosis function, reducing operational disruption and maintenance costs

Inventive Principle:
Principle #25Self-service

2Ease of manufacture

If components are replaced based on expected lifetime, then maintenance scheduling is simplified, but replacement may be premature or delayed

Engineering Contradiction:
Improvemaintenance scheduling simplicityVSAvoidcomponent service accuracy
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The sensing device provides real-time feedback on actual wear conditions of the track link. This feedback mechanism enables dynamic adjustment of maintenance scheduling based on actual component state rather than fixed time intervals, improving both the simplicity and accuracy of maintenance planning

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The sensing device detects wear trends before they reach critical levels, allowing proactive maintenance scheduling. By monitoring wear accumulation in real-time, the system enables planned replacement at optimal moments, preventing both premature replacement and delayed maintenance

Inventive Principle:
Principle #10Preliminary action

3Productivity

If inspection is performed manually, then costs and downtime are reduced, but measurement accuracy and reliability decrease

Engineering Contradiction:
Improveinspection efficiencyVSAvoidwear measurement accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The mechanical inspection process is replaced with an electronic sensing device embedded in the track link. This substitution provides continuous automated measurement of wear parameters, delivering both high measurement precision and operational efficiency without requiring manual intervention

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