Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tire pressure monitoring systems fail to alert operators when tire air pressure is insufficient for the given loading conditions, leading to potential tire rupture due to increased friction and uneven load distribution, even if the pressure is above the conventional alert threshold.
Innovation Solution
A chassis monitoring system that includes tire sensors to detect pressure and temperature, load sensors to measure actual load, and a controller to determine the theoretical load capacity based on tire conditions, generating alerts when the actual load exceeds the safe capacity, ensuring safe and comfortable vehicle handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional tire pressure monitoring system is used to alert operators when tire pressure reduces below a low-threshold limit, then the system is simple to operate and provides basic safety alerts, but it fails to detect insufficient tire pressure for given loading conditions when pressure remains above the alert threshold
Solution Approach 1:
The patent introduces an intermediary calculation process that compares actual load with theoretical load capacity derived from tire pressure and temperature. This intermediary comparison mechanism enables the system to detect loading conditions that conventional pressure-only systems miss, while the controller integrates these calculations without requiring separate complex subsystems.
Solution Approach 2:
The controller performs multiple functions: monitoring tire pressure, measuring temperature, detecting load, calculating theoretical load capacity, and generating alerts. By consolidating these diverse functions into a single control unit, the system achieves high detection accuracy without proportionally increasing overall system complexity.
2Reliability
If the tire pressure is maintained above the conventional alert threshold, then the tire appears to be adequately inflated, but the tire may still be insufficient for the given loading condition, increasing friction and rupture risk
Solution Approach 1:
The system performs preliminary detection by continuously monitoring tire pressure, temperature, and load conditions before dangerous situations develop. By calculating theoretical load capacity in advance and comparing it with actual load, the system can alert operators to potential overload conditions before they lead to increased friction and tire rupture.
Solution Approach 2:
The system establishes a feedback loop that continuously monitors tire conditions and load, compares actual load with theoretical capacity, and provides real-time alerts to operators. This closed-loop feedback enables dynamic adjustment of loading behavior based on current tire conditions, preventing harmful friction and rupture risks.
3Measurement precision
If the system monitors only tire pressure without considering load, then the monitoring system is simple, but it cannot determine whether the tire pressure is sufficient for the actual loading condition
Solution Approach 1:
The patent merges pressure sensing, temperature sensing, and load detection into a unified monitoring system. The controller integrates data from tire pressure sensors, temperature sensors, and load sensors to calculate theoretical load capacity, achieving precise load capacity assessment through the combination of multiple measurement types rather than through a single complex sensor.

Implementation Method 1
a plurality of tire sensors, each associated with a corresponding tire of the plurality of tires and configured to generate a first signal indicative of at least one of a pressure and a temperature of the corresponding tire

Data Source
AI summary
A monitoring system is disclosed for use with a rolling chassis of a vehicle. The monitoring system may include a tire sensor configured to generate a first signal indicative of a current tire condition of the rolling chassis, and a load sensor configured to generate a second signal indicative of an actual load placed on the rolling chassis. The monitoring system may also include a controller in communication with the tire sensor and the load sensor. The controller may be configured to determine based on the first signal a theoretical load that the rolling chassis is capable of supporting given the current tire condition. The controller may also be configured to make a first comparison of the actual load with the theoretical load, and to selectively generate a first alert based on the first comparison.
