Solution Overview

Problem

Conventional automotive maintenance schedules are often based on fixed intervals, which can lead to inconvenient service trips and safety hazards due to unforeseen component failures, especially in autonomous vehicles where timely intervention is critical.

Innovation Solution

Implementing a predictive maintenance system using artificial neural networks (ANNs) that analyze sensor data from vehicles to detect anomalies and predict maintenance needs, allowing for proactive scheduling and reducing the likelihood of component failures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional fixed-interval maintenance scheduling is used, then maintenance services can be scheduled regularly, but service trips may occur at inconvenient times and component failures can still happen unexpectedly

Engineering Contradiction:
Improvecomponent failure prediction accuracyVSAvoidmaintenance scheduling flexibility
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary analysis of sensor data using neural networks to predict component failures before they occur. This allows maintenance to be scheduled proactively based on actual component condition rather than waiting for fixed intervals, thereby improving reliability while optimizing maintenance timing to avoid inconvenient service trips

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously collects sensor data from vehicle components and feeds it back through neural network models to update failure predictions. This feedback mechanism enables dynamic adjustment of maintenance schedules based on real-time component health status, resolving the contradiction between reliable failure prediction and flexible scheduling

Inventive Principle:
Principle #23Feedback

2Measurement precision

If more sensor data is collected for better prediction accuracy, then component failure can be predicted more accurately, but system complexity and computational load increase

Engineering Contradiction:
Improvesensor data analysis accuracyVSAvoidneural network system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The neural network system is segmented into multiple specialized models, each trained to predict specific component failures (e.g., battery failure model, motor failure model). This segmentation allows the system to process sensor data more efficiently by routing different data types to appropriate models, improving prediction accuracy while managing system complexity through modular architecture

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system extracts only the most relevant sensor data features for each specific component prediction task rather than processing all available sensor data uniformly. This feature extraction approach reduces computational load and system complexity while maintaining high measurement precision for each component's failure prediction

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Systems, methods and apparatus of predictive maintenance of automotive tires. For example, a vehicle has: a tire and wheel assembly; one or more sensors configured on the tire and wheel assembly to measure operating parameters of the tire and wheel assembly; an artificial neural network configured to analyze the operating parameters of the tire and wheel assembly as a function of time to generate a result; and at least one processor configured to generate a suggestion for a maintenance service of the tire and wheel assembly based on the result from the artificial neural network analyzing the operating parameters of the tire and wheel assembly. For example, the sensors can be configured to measure a pressure of air in the tire, a temperature of the air in the tire, a speed of spinning of the wheel, a traction force or torque applied by the wheel on an axle of the vehicle, and/or vibration of the wheel.
