Solution Overview

Problem

Existing telematics systems in commercial vehicle trailers only allow for fault codes to be analyzed individually, limiting the ability to identify and address potential issues across multiple trailers effectively.

Innovation Solution

A centralized system utilizing one or more servers to receive, evaluate, and analyze fault codes from multiple trailers, identifying statistical anomalies and generating user information for proactive maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If fault codes are analyzed individually for each trailer, then detailed information about each specific trailer condition is obtained, but the ability to identify and address potential issues across multiple trailers is limited

Engineering Contradiction:
Improvefault code analysis capabilityVSAvoidcross-trailer issue identification
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent combines fault code data from multiple trailers into a centralized database, enabling aggregation and comparison of fault information across the entire fleet. This merging allows the system to identify common patterns and statistical anomalies that would be invisible when analyzing individual trailers in isolation, thus resolving the contradiction between detailed individual analysis and cross-trailer issue identification.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If telematics data is collected from multiple trailers, then group-based analysis becomes possible, but the system complexity increases

Engineering Contradiction:
Improvemaintenance efficiencyVSAvoiddata collection system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a server as an intermediary component that receives, stores, and processes telematics data from multiple trailers. This centralized server acts as a mediator between the distributed trailers and the analysis functions, enabling group-based analysis without requiring complex peer-to-peer communication or distributed processing across all trailers, thus managing system complexity while improving maintenance efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If statistical evaluation of fault codes is performed, then early detection of potential issues is enabled, but additional processing time and resources are required

Engineering Contradiction:
Improveearly issue detectionVSAvoiddata processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent performs statistical evaluation and anomaly detection proactively on accumulated fault code data before actual failures occur. By continuously analyzing fault patterns and identifying statistical anomalies in advance, the system enables early detection of potential issues across the fleet, allowing preventive maintenance actions to be taken before problems escalate, thus improving reliability while the processing is distributed over time rather than requiring intensive real-time analysis.

Inventive Principle:
Principle #10Preliminary action
