Vehicle Part Wear Detection and Proactive Maintenance Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to effectively inform vehicle owners about the wear of various parts, such as tires and shock absorbers, leading to potential safety and comfort issues, and are not user-friendly, as they require manual checks or provide notifications while driving.
Innovation Solution
A method that determines the remaining service life of vehicle parts by measuring physical parameters and sending reminders to users when parts need replacement, allowing for proactive maintenance planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wear indicators are installed on tyres to allow visual determination of wear, then the user can visually determine tyre wear, but the user must remember to check tyres regularly which is not reliable
Solution Approach 1:
The system performs automatic wear detection without requiring user action. Sensors continuously monitor part wear and the system automatically calculates remaining service life, eliminating the need for manual visual checks by the user.
Solution Approach 2:
The system provides continuous feedback to the user through automated notifications about part wear status and remaining service life. This feedback mechanism ensures the user is informed without needing to actively check parts.
2Speed
If wear information is provided to the driver while driving, then the driver receives real-time information, but the driver cannot note the information and may forget it after returning home
Solution Approach 1:
The system sends notifications to the user's mobile device or email in advance, allowing the user to review and note the information at their convenience before returning home, rather than relying on memory after the driving trip.
Solution Approach 2:
The system uses an intermediary communication channel (mobile device or email) to transfer wear information from the vehicle system to the user, ensuring the information is preserved and can be reviewed later without relying on the driver's memory.
3Measurement precision
If garage visits are used to check part wear, then a mechanic can perform the check, but the frequency of visits is not high enough to guarantee correct detection of part wear
Solution Approach 1:
The system provides continuous monitoring of part wear between garage visits using sensors and automated systems. This continuous action ensures wear is detected promptly without waiting for periodic manual inspections.
4Adaptability or versatility
If a system monitors wear of multiple vehicle parts, then comprehensive maintenance information is provided, but the system complexity increases
Solution Approach 1:
The system uses a universal platform that can monitor multiple different vehicle parts (tyres, brake linings, shock absorbers) using similar sensor and processing architectures. This multi-functionality approach allows comprehensive monitoring without proportionally increasing system complexity.

AI summary
In a method of determining a remaining capacity for use of a vehicle part of a motor vehicle, a state of wear of the vehicle part is determined, a remaining distance that can be covered before the vehicle part becomes completely worn is calculated as a function of a type of the vehicle part and the state of wear of the vehicle part, and a remaining service life before the vehicle part must be changed is calculated as a function of an average distance covered by the motor vehicle annually and the remaining distance that can be covered before the vehicle part becomes completely worn.
