Solution Overview

Problem

Existing systems struggle to accurately differentiate between wireless signals of multiple work implements at a worksite, leading to inaccurate tracking and potential machine downtime and damage.

Innovation Solution

A tracking system that utilizes a component beacon device with a unique identifier, combined with communication controllers to monitor message counts from beacon devices, allowing for the identification of the most relevant signal associated with the attached component, and transmitting this data to a useful life estimation system for precise tracking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wireless communication is used to track work implements, then tracking capability is improved, but signal differentiation accuracy deteriorates due to multiple beacon devices at the worksite

Engineering Contradiction:
Improvetracking accuracyVSAvoidsignal differentiation accuracy
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The system segments the tracking problem by dividing beacon devices into two categories: component beacon devices (attached to work implements) and non-component beacon devices (portable or on other equipment). The communication controller separately monitors and processes signals from these two groups, applying different tracking logic to each segment to resolve signal differentiation issues.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The communication controller acts as an intermediary that receives signals from multiple beacon devices, processes them through message count analysis, and determines which signals correspond to actually attached components. This intermediary processing layer filters out false signals from non-attached beacons before transmitting tracking data to the useful life estimation system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If message count monitoring is used to identify attached components, then component identification accuracy is improved, but system complexity increases due to continuous signal monitoring and analysis

Engineering Contradiction:
Improvecomponent identification accuracyVSAvoidsignal processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system uses the inherent characteristics of beacon signals (their periodic transmission nature) to self-identify attached components. By monitoring message counts over time, the system automatically distinguishes between attached and non-attached beacons without requiring additional sensors or complex external verification systems. The beacon devices themselves provide the information needed for identification through their signal presence.

Inventive Principle:
Principle #25Self-service
