Vehicle Evaluation Using Historical Data Authenticity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle evaluation methods are limited to assessing only the current condition of vehicles, making it difficult to detect past faults, accidents, or historical usage, resulting in poor accuracy of evaluations.
Innovation Solution
A vehicle evaluation method that obtains current and historical vehicle data using vehicle identification, determines the authenticity of the current data by comparing it with historical data, and generates an evaluation report based on the authenticity, including performance and condition assessments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only current vehicle data is collected for evaluation, then the evaluation process is simple and fast, but the accuracy of vehicle evaluation is poor and historical faults cannot be detected
Solution Approach 1:
The system performs preliminary actions by collecting and storing historical vehicle data (maintenance records, fault information, mileage data) in advance through various channels such as 4S stores, repair shops, and vehicle sensors. This pre-collected historical data is then used during the evaluation process to accurately detect past faults and assess the vehicle's true condition, resolving the contradiction between evaluation accuracy and process complexity.
2Loss of information
If professional evaluators manually detect vehicle conditions, then detailed inspection can be performed, but the evaluation is limited to current state and cannot reveal historical usage conditions
Solution Approach 1:
The patent introduces an intermediary vehicle evaluation system that acts as a mediator between various data sources (4S stores, repair shops, sensors) and the final evaluation result. This system automatically collects, stores, and processes historical vehicle data through standardized interfaces, eliminating the need for manual information gathering and ensuring complete vehicle information is available without significant time loss.
3Measurement precision
If comprehensive historical data is collected and analyzed, then the accuracy of vehicle evaluation improves, but the complexity of data processing increases
Solution Approach 1:
The system creates simplified copies or representations of complex historical data through standardized data structures and formats. Historical maintenance records, fault information, and mileage data are copied into a unified evaluation database with consistent schemas, allowing accurate authenticity determination without requiring complex processing of raw heterogeneous data from multiple sources.
