Vehicle Overwork Consumable Detection via Vibration and OBD Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automotive manufacturers and repair shops provide non-uniform replacement cycles for vehicle consumables, leading to confusion among drivers due to varying environmental conditions, and existing solutions do not effectively determine overworked consumables based on vehicle and vibration information.
Innovation Solution
An apparatus that uses vehicle information and vibration data from sensors to determine overwork condition types, registers GPS locations for maintenance, and informs drivers through AVN systems, predicting replacement dates and identifying severely overworked consumables via OBD and AVN notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manufacturers and repair shops provide replacement cycles through manuals, then drivers can obtain maintenance information, but drivers experience confusion due to non-uniform replacement cycles and varying environmental conditions
Solution Approach 1:
The patent replaces the manual-based mechanical information delivery system with an electronic diagnostic system that automatically collects vehicle data through OBD communication and vibration sensors, processes this data through a diagnosis server, and provides personalized maintenance recommendations, thereby eliminating the confusion caused by generic manual instructions
Solution Approach 2:
The system enables the vehicle itself to monitor its own condition through integrated sensors and OBD diagnostics, automatically determining when maintenance is needed based on actual vehicle state rather than relying on drivers to follow generic manual schedules, thus providing self-adaptive maintenance information
2Ease of operation
If replacement cycles are standardized in manuals, then maintenance scheduling becomes simple, but the cycles do not account for varying environmental conditions and actual vehicle usage
Solution Approach 1:
The patent transitions from static, fixed replacement cycles in manuals to dynamic, adaptive maintenance scheduling that continuously updates based on real-time vehicle data including vibration patterns, operational conditions, and environmental factors, allowing the maintenance schedule to adapt to actual vehicle usage and conditions
Solution Approach 2:
The system implements continuous feedback loops where vibration sensors and OBD diagnostics monitor vehicle condition, the diagnosis server analyzes this data to determine actual consumable wear rates, and maintenance recommendations are adjusted accordingly, creating a closed-loop system that accounts for varying environmental conditions and usage patterns
3Measurement precision
If vibration sensors and OBD systems are integrated to determine overwork conditions, then maintenance accuracy improves, but system complexity increases
Solution Approach 1:
The patent leverages existing multi-functional components - the OBD system serves both as a diagnostic interface and a data communication channel, while vibration sensors simultaneously monitor both vehicle health and consumable wear conditions, reducing the need for dedicated separate systems and mitigating complexity increases
Solution Approach 2:
The diagnosis server acts as an intermediary that handles the complex data processing, analysis, and decision-making algorithms, isolating the complexity from the vehicle's onboard systems. The server receives raw data from simple sensors and OBD, performs sophisticated analysis, and returns simplified maintenance recommendations, thereby managing system complexity externally
