Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle data storage systems are vulnerable to data loss and integrity issues during accidents, particularly when non-volatile memory is damaged, necessitating improved data storage methods to ensure accessibility and integrity.
Innovation Solution
A data storage system for motor vehicles utilizing a blockchain architecture across multiple secure circuits, where each circuit searches for a proof of work to validate and store data values, ensuring data integrity and redundancy by distributing the storage across the vehicle network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored in a single non-volatile memory, then the storage structure is simple, but the data may be lost if the memory is damaged
Solution Approach 1:
The patent divides the storage system into multiple independent circuits (at least two circuits), each storing identical data in its own non-volatile memory. This segmentation ensures that if one circuit or memory is damaged, the data remains accessible through other circuits, directly resolving the contradiction between reliability and structural simplicity.
2Reliability
If data is stored in multiple circuits, then data redundancy and integrity are improved, but the system complexity increases
Solution Approach 1:
The patent creates identical copies of the data in multiple circuits' non-volatile memories. Each circuit stores the same data values, creating redundant copies that ensure data integrity even if one copy is corrupted or lost, while maintaining relatively simple system architecture.
3Reliability
If proof of work verification is implemented across multiple circuits, then data security is enhanced, but the processing time increases
Solution Approach 1:
The patent merges the proof of work verification process across multiple circuits, where each circuit independently verifies the proof of work for data stored in its non-volatile memory. This parallel verification approach enhances data security through multiple verification instances while minimizing time loss by performing verifications simultaneously rather than sequentially.

AI summary
The present description concerns a method comprising: transmitting, by at least one peripheral circuit of a storage system for a motor vehicle, one or more data values to be stored, to at least two circuits of the vehicle; searching for a proof of work; transmitting, when a first one of the at least two circuits has found a potential proof of work, the potential proof of work to each of the other circuits; verifying the potential proof of work; and, if the verification confirms that the potential proof of work matches the proof of work searched for, the storage, in each of the circuits, of one or more data values in a current block of a blockchain, the one or more data values being stored in association with an identification value identifying the previous block, the proof of work, and an identification value identifying the current block.
