Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery stations face a high risk of battery loss due to data loss and the mixing of batteries from different companies, making it difficult to track and identify missing batteries effectively.
Innovation Solution
A battery station management server utilizing a smart contract to manage battery rental information, including authentication and information storage, to track and authenticate battery rental and return requests, and identify potential battery loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If batteries from multiple companies are shared and mixed at battery stations, then battery utilization and adaptability are improved, but the risk of battery loss increases due to difficulty in tracking individual batteries
Solution Approach 1:
The patent introduces a smart contract as an intermediary mechanism between battery stations and users. The smart contract automatically tracks battery rental and return transactions, maintaining a ledger that records which battery belongs to which company and its current status. This intermediary system enables multi-company battery sharing while preventing loss by continuously monitoring battery flow across different stations and companies.
2Device complexity
If traditional database systems are used to manage battery rental data, then implementation complexity is low, but data loss occurs and battery loss cannot be quickly identified
Solution Approach 1:
The patent uses smart contracts to create an immutable copy of battery rental information on a blockchain. Instead of relying on a single centralized database that can be corrupted or lose data, the system creates a distributed copy of the rental ledger across multiple nodes. This copy mechanism ensures that battery rental and return data is permanently recorded and cannot be lost or altered, while still maintaining relatively simple implementation through standardized smart contract templates.
3Reliability
If detailed battery tracking is implemented to prevent data loss, then battery loss identification improves, but system complexity and data management burden increase
Solution Approach 1:
The patent extracts critical battery tracking functionality from complex centralized databases and implements it through a simplified smart contract system. The smart contract automatically handles authentication, rental recording, and return verification without requiring complex data management infrastructure. By taking out the essential tracking function and implementing it through blockchain technology, the system achieves reliable battery loss identification while reducing overall data management complexity.
