Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for monitoring tire temperature inside a rubber mixture in heavy civil engineering vehicles are complex, costly, and disrupt mining operations, as they require manual installation of sensors and frequent vehicle stops, making them unsuitable for real-time, non-destructive, and automatic temperature measurement.
Innovation Solution
A method involving the identification of specific zones on the tire for sensor insertion, drilling with a cylindrical drill bit, and securing temperature sensors with a microprocessor and radio transmission capabilities within the tire, using a device to evacuate air and seal the cavity, allowing for real-time temperature monitoring without stopping the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual sensor installation and frequent vehicle stops are used for temperature monitoring, then temperature measurement accuracy is improved, but mining operation productivity deteriorates
Solution Approach 1:
Temperature sensors are pre-installed in the tire during manufacturing before the tire is put into service. This preliminary action eliminates the need for manual installation and vehicle stops during operation, allowing continuous temperature monitoring without disrupting mining productivity while maintaining measurement accuracy
Solution Approach 2:
The tire incorporates integrated temperature sensors and a processing unit that automatically monitor and analyze temperature data during normal operation. The system serves itself by continuously collecting thermal data without requiring external intervention, vehicle stops, or manual sensor installation, thus maintaining both measurement precision and operational productivity
2Reliability
If complex manual sensor installation methods are used, then temperature measurement capability is improved, but device complexity and installation cost increase
Solution Approach 1:
The temperature monitoring system merges multiple functions into an integrated unit: temperature sensors are embedded within the tire structure, connected to a processing unit that handles data collection, analysis, and transmission. This consolidation eliminates complex separate installation procedures while maintaining reliable temperature monitoring capability
Solution Approach 2:
The integrated processing unit performs multiple functions: it collects data from multiple temperature sensors, processes the thermal information, determines temperature evolution, and transmits alerts. This multi-functional design simplifies the overall system while ensuring reliable temperature monitoring without requiring complex specialized components
