Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to determine if tire rotations have been correctly performed and if the new locations of tires match the specified tire rotation map, as existing systems lack effective monitoring and verification methods.
Innovation Solution
A tire pressure and location monitoring system that includes sensors to track tire pressure, mileage, and location, comparing new tire positions post-rotation against a stored tire rotation map, and generating messages or error messages based on correct or incorrect alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tire rotation is performed manually without verification, then tire maintenance can be completed, but it cannot be determined whether the new locations match the specified tire rotation map
Solution Approach 1:
The system implements feedback by continuously monitoring tire pressure sensor locations and comparing them against the expected tire rotation map. After rotation, the system receives new location data from sensors and provides feedback through service indicators that confirm whether the rotation was performed correctly, enabling verification without adding manual complexity
Solution Approach 2:
The system performs self-verification by automatically detecting tire sensor locations and comparing them against the stored rotation map. The tire pressure monitoring system itself provides the verification function, eliminating the need for separate manual verification procedures while maintaining ease of operation
2Productivity
If tire rotation is performed without location verification, then maintenance time is reduced, but tire wear uniformity cannot be ensured
Solution Approach 1:
The system stores the tire rotation map in advance before rotation occurs. By having the expected location configuration pre-programmed in the controller, the system can quickly verify rotation correctness after the fact without requiring time-consuming manual checks, thus maintaining productivity while ensuring reliability through accurate verification
Solution Approach 2:
The system replaces manual verification methods with electronic detection using tire pressure sensors and a controller. Instead of physically checking tire locations, the system uses electronic signals from sensors to automatically determine sensor locations and compare them against the stored rotation map, enabling fast and reliable verification
3Measurement precision
If a tire rotation monitoring system is implemented, then rotation correctness can be verified, but system complexity increases
Solution Approach 1:
The system achieves rotation verification by integrating it with the existing tire pressure monitoring system. The same tire pressure sensors serve dual purposes: monitoring tire pressure and identifying tire locations. The controller performs both pressure monitoring and location verification functions, eliminating the need for separate dedicated verification hardware and reducing overall system complexity
Solution Approach 2:
The system uses a digital copy of the tire rotation map stored in the controller to verify actual tire locations. By comparing sensor-reported locations against the stored map copy, the system achieves accurate verification without requiring complex physical measurement devices or additional sensors
4Measurement precision
If tire locations are tracked using additional sensors, then location accuracy improves, but cost and system complexity increase
Solution Approach 1:
The system makes the existing tire pressure sensors multi-functional by having them report both pressure data and location information. The sensors communicate their identity and location to the controller, which uses this information for verification without requiring any additional location-specific sensors, thus maintaining precision while avoiding increased complexity
