Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for recording vehicle mileage data rely on odometers, which can be manually adjusted, leading to mistrust and inaccuracies in distance tracking.
Innovation Solution
A method and apparatus for recording mileage data on a blockchain, involving a vehicle database for unique identification and a mileage database for storing travel data, with the data being stored on a blockchain for immutability and authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mileage data is recorded using traditional odometers, then the recording process is simple and easy to implement, but the data can be manually adjusted leading to mistrust and inaccuracies
Solution Approach 1:
The patent introduces a blockchain system as an intermediary between the odometer and the final record. The odometer data is transmitted to a server that then stores it on the blockchain, creating a trusted intermediary layer that prevents manual adjustment while maintaining the simplicity of the original odometer mechanism.
Solution Approach 2:
The patent replaces the mechanical/trust-based odometer system with a cryptographic blockchain system. Instead of relying on the physical integrity of the odometer mechanism, the solution uses digital hashing, decentralized storage, and cryptographic verification to ensure data authenticity, substituting mechanical trust with computational trust.
2Reliability
If mileage data is stored on a blockchain, then the data becomes tamper-proof and authentic, but the system complexity increases
Solution Approach 1:
The patent divides the system into distinct functional modules: the odometer component, the transmission component, the server component, and the blockchain storage component. Each module performs a specific function, allowing the complex blockchain integration to be managed through clear separation of concerns and modular architecture.
3Measurement precision
If vehicle mileage data is tracked continuously, then accurate vehicle history evaluation is achieved, but more data storage and processing resources are required
Solution Approach 1:
The patent creates cryptographic copies (hashes) of the mileage data that are stored on the blockchain. Instead of storing only the raw mileage numbers, the system generates cryptographic representations that verify authenticity without requiring storage of all raw data, reducing storage requirements while maintaining verification capabilities.
