Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is stored in mobile terminal devices for virtual storage, then resource utilization is improved, but security deteriorates due to risk of information leakage
Solution Approach 1:
The patent divides stored data into multiple separate data fragments and distributes them across multiple mobile terminal devices. No single device contains the complete data, so even if one device is compromised, the full data cannot be reconstructed. This segmentation approach enables secure distributed storage while maintaining high resource utilization of mobile devices.
Solution Approach 2:
The patent introduces an encryption system as an intermediary between the data and storage devices. Data is encrypted before being fragmented and distributed, and only authorized users with decryption keys can reconstruct the original data. This intermediary layer protects against information leakage while enabling remote access to stored data.
2Adaptability or versatility
If wireless communication is used for mobile terminal connectivity, then adaptability is improved, but reliability deteriorates due to unstable communication
Solution Approach 1:
The patent implements local storage of data fragments on mobile terminal devices, making the storage system independent of continuous wireless communication. Each device locally holds encrypted data fragments that can be retained even when communication is interrupted. This local quality approach allows the system to adapt to varying network conditions while maintaining data integrity.
Solution Approach 2:
The patent prepares for communication failures by pre-distributing data fragments to multiple devices before any potential communication issues arise. This redundancy ensures that even if wireless communication becomes unstable or interrupted, the data remains accessible through other devices in the distributed network.
3Reliability
If data is distributed across multiple mobile terminals, then redundancy is improved, but device complexity increases
Solution Approach 1:
The patent creates multiple copies of fragmented data across different mobile terminal devices, establishing redundancy without requiring complex coordination between devices. Each device independently stores its assigned data fragments, simplifying the overall system architecture while ensuring data availability through multiple copies.
Solution Approach 2:
The patent enables each mobile terminal device to independently manage its own data fragments with minimal central coordination. Devices autonomously store, retain, and transmit their assigned fragments, reducing the complexity of centralized management while maintaining system-wide redundancy and reliability.
