Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automotive maintenance systems fail to predict vehicle breakdowns accurately and recommend timely repairs, leading to potential accidents and social losses due to unawareness of part damage and importance of replacement.
Innovation Solution
An apparatus and method that create vehicle diagnosis information using real-time data from sensors, predicting breakdowns by analyzing vibration signals and recommending repair shops based on a preventive maintenance emergency degree, providing compensation for necessary maintenance services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If collective replacement time is used for maintenance, then maintenance scheduling is simplified, but breakdown prediction accuracy deteriorates
Solution Approach 1:
The system changes the parameter basis for maintenance scheduling from fixed collective time/mileage to dynamic real-time diagnostic parameters including vibration frequency, temperature, and wear indicators. This allows maintenance to be scheduled based on actual part condition rather than predetermined intervals, resolving the contradiction between operational simplicity and prediction accuracy.
Solution Approach 2:
The patent replaces the mechanical timing-based maintenance system with an electronic diagnostic system that uses sensors and data processing to monitor part conditions. This substitution enables continuous real-time monitoring and accurate breakdown prediction while maintaining ease of operation through automated alert systems.
2Measurement precision
If real-time diagnosis is implemented, then breakdown prediction accuracy is improved, but system complexity increases
Solution Approach 1:
The diagnostic system is segmented into modular components: vibration sensors, temperature sensors, data processing units, and alert generation systems. Each module performs a specific function, making the overall complex system manageable and maintainable while achieving high breakdown prediction accuracy through coordinated operation of these segmented elements.
Solution Approach 2:
The system incorporates self-diagnostic capabilities where the vehicle's own sensors and processing units continuously monitor part conditions without requiring external intervention. This self-service approach enables accurate real-time diagnosis while reducing the complexity of external monitoring infrastructure.
3Loss of energy
If preventive maintenance is delayed until breakdown occurs, then maintenance costs are reduced, but safety and social losses worsen
Solution Approach 1:
The system performs preliminary diagnostic actions by continuously monitoring part conditions and predicting breakdowns before they occur. This allows maintenance to be scheduled in advance based on actual part wear, preventing safety incidents while optimizing maintenance costs by avoiding both premature and delayed maintenance.
Solution Approach 2:
The patent implements a feedback mechanism where diagnostic data from sensors continuously informs maintenance decisions. This closed-loop system provides real-time feedback on part conditions, enabling timely maintenance interventions that balance cost efficiency with safety requirements by acting before breakdowns occur but not unnecessarily early.

AI summary
An apparatus for providing an automotive preventive maintenance service includes: a vehicle information creator that creates vehicle information including vehicle diagnosis information obtained in real time while a vehicle is driven and vehicle state information showing a current state of the vehicle; a vehicle breakdown generation predictor that creates vehicle part states each composed of a preventive maintenance emergency degree and a vehicle part on the basis of the vehicle information, and predicts breakdown generation of the vehicle; an automotive repair shop recommender that recommends an automotive repair shop based on a cost or a distance on the basis of the preventive maintenance emergency degree in at least one of the vehicle part states; and a preventive maintenance service compensator that detects whether to perform a maintenance service about a corresponding vehicle part state according to the preventive maintenance emergency degree, and provides preventive maintenance service compensation.
