Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tire temperatures can rise to the point of failure during high ambient temperatures, posing a safety concern due to unexpected extreme tire failures, necessitating a system to detect and prevent temperature-related tire damage.
Innovation Solution
A tire temperature monitoring system with a sensor assembly in proximity to the tire, connected to a processor that provides alerts and optionally applies coolant when the tire temperature exceeds a predetermined range, using haptic, audio, or visual signals and varying intensity or frequency to warn the driver and reduce tire temperature.

Engineering Contradiction Analysis
1Reliability
If a temperature monitoring and warning system is implemented, then tire safety is improved, but device complexity increases
Solution Approach 1:
The system is divided into separate functional modules: temperature sensor assembly mounted on the wheel, processor unit, warning system components (visual, audio, haptic), and coolant system. Each module operates independently but communicates through the processor, allowing the complex safety function to be achieved through modular, manageable components rather than a monolithic system.
Solution Approach 2:
The processor serves multiple functions: receiving temperature data from the sensor, comparing it against threshold values, controlling the warning system outputs, and managing the coolant system activation. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing system complexity while maintaining comprehensive safety monitoring.
2Temperature
If coolant is applied to reduce tire temperature, then tire temperature is reduced, but energy consumption increases
Solution Approach 1:
The system applies coolant only when the temperature sensor detects that the tire temperature exceeds the predetermined threshold range. This conditional activation means the cooling system operates preemptively only when necessary, rather than continuously, thereby reducing energy consumption while still effectively preventing overheating when the risk is present.
Solution Approach 2:
The warning system and coolant application operate periodically or intermittently based on temperature threshold breaches rather than continuously. The processor monitors temperature continuously but activates cooling only during periods when thresholds are exceeded, creating a periodic action pattern that reduces overall energy consumption compared to continuous operation.
