Solution Overview

Problem

Thermal events such as fires can occur in trailer wheel areas due to overheating caused by brake dragging, inadequate lubrication, incorrect air valves, or improper tire pressure, leading to destruction of the trailer and potential accidents, with current solutions lacking active monitoring and warning systems.

Innovation Solution

A thermal monitoring system for trailers that includes sensors at critical areas (tire, brake, and wheel) to detect temperature changes, a main controller to trigger alerts and warnings, and a telematics device for communication with headquarters, enabling proactive measures to prevent damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If thermal monitoring sensors are installed in critical areas (tire, brake, wheel end), then thermal events can be detected early and alerts can be triggered, but the device complexity increases

Engineering Contradiction:
Improvethermal event detection capabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The monitoring system is divided into multiple independent temperature sensors placed at different critical locations (tire, brake, wheel end), each independently detecting thermal events. This segmentation allows comprehensive monitoring while keeping individual sensor components simple and manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The main controller serves multiple functions: receiving data from multiple sensors, processing temperature readings, triggering alerts, and communicating with headquarters. This multi-functionality consolidates system complexity into a single control unit rather than requiring separate systems for each function.

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

2Measurement precision

If multiple sensors are deployed to monitor all critical areas, then measurement precision improves, but the cost and complexity of the system increases

Engineering Contradiction:
Improvetemperature monitoring accuracyVSAvoidsensor network complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Temperature sensors are strategically placed at specific critical locations (tire, brake, wheel end) where thermal events are most likely to occur. This localized monitoring approach provides precise measurement where needed most without requiring comprehensive coverage of the entire trailer, optimizing the balance between measurement precision and system complexity.

Inventive Principle:
Principle #3Local quality

3Loss of time

If real-time monitoring and alert systems are implemented, then response time to thermal events improves, but energy consumption increases

Engineering Contradiction:
Improveresponse time to thermal eventsVSAvoidenergy consumption
Core Design Contradiction:
Loss of timeVSUse of energy by moving object

Solution Approach 1:

The system continuously monitors temperature data and compares it against pre-defined thresholds, triggering alerts only when thermal events are detected. This periodic checking with event-driven alerting provides rapid response capability while avoiding continuous high-energy operations, as the system remains in a low-power state until thermal anomalies occur.

Inventive Principle:
Principle #19Periodic action
