In-Vehicle Device Condition Evaluation Using Load Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abandoned vehicle purchase estimation systems lack accuracy in identifying reusable in-vehicle parts, leading to potential recycling of parts that are not actually reusable, thus inefficiently proceeding with the recycle and reuse of in-vehicle devices.
Innovation Solution
A condition evaluation system that acquires load information from in-vehicle devices and derives a condition rank based on this information, indicating whether the device or its components should be recycled, reused, or remanufactured, and stores this rank for determination of transaction prices and logistics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sections are determined to include reusable parts based on appearance and travel distance, then the estimation process is simplified, but the accuracy of identifying truly reusable parts deteriorates
Solution Approach 1:
The system performs preliminary evaluation of part reusability by acquiring load information and deriving condition ranks before the actual recycling decision is made. This preliminary action based on objective load data helps pre-identify potentially reusable parts, making the subsequent estimation process more accurate while still maintaining operational simplicity.
Solution Approach 2:
The system establishes a feedback mechanism where condition ranks derived from load information are stored and can be referenced for future recycling decisions. This feedback loop allows the system to continuously improve its accuracy in identifying reusable parts while maintaining the simplified estimation process.
2Measurement precision
If condition evaluation based on load information is implemented, then the accuracy of recycling decisions is improved, but the system complexity increases
Solution Approach 1:
The evaluation system is segmented into distinct functional modules: an acquisition unit for collecting load information, an evaluation unit for deriving condition ranks, and a storage unit for saving evaluation results. This segmentation reduces overall system complexity by making each component's function clear and manageable while maintaining high accuracy in recycling decisions.
Solution Approach 2:
The condition rank serves as an intermediary parameter between the raw load information and the final recycling decision. Instead of directly complexly analyzing all load data for each recycling decision, the system uses the pre-derived condition rank as a simplified intermediate representation, reducing the complexity of the overall evaluation process.
3Reliability
If load information is continuously acquired and condition ranks are derived, then the reliability of recycling decisions is improved, but the processing time increases
Solution Approach 1:
The system performs preliminary acquisition of load information and derivation of condition ranks during the vehicle's operational life before recycling is needed. This preliminary action ensures that when recycling decisions must be made, the evaluation is already complete, improving reliability without adding time to the actual recycling process.
Solution Approach 2:
The evaluation unit automatically acquires load information and derives condition ranks without requiring manual intervention or additional processing time at the point of recycling decision. The system serves itself by continuously monitoring and evaluating its own components, ensuring reliable decisions are made quickly when needed.

AI summary
A condition evaluation system evaluates a condition of an in-vehicle device installed in a vehicle. The condition evaluation system includes: an evaluation unit configured to acquire load information indicating a load on the in-vehicle device when the vehicle is used and, each time the load information is acquired, derive a condition rank of the in-vehicle device based on the load information, the condition rank indicating at least whether the in-vehicle device should be recycled; and a storage unit configured to store the condition rank derived by the evaluation unit.
