Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is encrypted using preconfigured systems with embedded encryption keys, then data security is improved, but the encryption keys may be held by multiple parties including cloud storage service providers, reducing security reliability
Solution Approach 1:
The patent extracts the encryption key management function from the cloud storage service provider and places it in the user's control. The system uses a key management service that resides on the user's device or in a trusted environment, separating the key holder (user) from the data holder (cloud provider), thereby maintaining security while simplifying key management.
Solution Approach 2:
The patent introduces a key management service as an intermediary between the user and the cloud storage system. This intermediary manages encryption keys securely, allowing the user to encrypt data before upload without requiring the cloud provider to have access to the keys, thus resolving the security-reliability issue.
2Quantity of substance
If data compression is handled by user intervention using data compression utilities, then space utilization is improved, but the process becomes cumbersome and requires repeated user intervention, reducing ease of operation
Solution Approach 1:
The patent implements automatic data compression through the file system driver, which performs compression transparently without requiring user intervention. The system automatically identifies suitable files, compresses them using appropriate algorithms, and manages the compressed data, allowing continuous space optimization while maintaining ease of operation.
Solution Approach 2:
The patent performs data compression as a preliminary action during the file write operation, before data is transferred to external storage. The file system driver intercepts write operations, compresses the data in advance, and then writes the compressed data, eliminating the need for separate user-initiated compression steps.
3Reliability
If compression and encryption are applied manually before data transfer, then data protection is improved, but the process requires repeated user intervention and is time-consuming, reducing productivity
Solution Approach 1:
The patent applies both compression and encryption as preliminary actions through the file system driver before data leaves the user's device. The driver intercepts file operations, performs compression and encryption automatically, and prepares the data for transfer, eliminating manual preprocessing steps and improving productivity while maintaining strong data protection.
Solution Approach 2:
The patent merges multiple data protection functions (compression, encryption, and secure transfer) into a single integrated file system driver layer. This consolidation allows all transformations to occur automatically in one pass through the driver, improving productivity by eliminating separate manual operations while maintaining comprehensive data protection.
4Ease of operation
If data transforms are applied transparently through file system driver, then ease of operation is improved, but the system complexity increases, requiring automatic detection and redirection mechanisms
Solution Approach 1:
The patent uses the file system driver as an intermediary layer between applications and the storage system. This driver transparently intercepts file operations, applies necessary transforms (compression, encryption), and manages data flow, providing ease of operation to users while containing system complexity within the driver layer rather than requiring complex user-facing mechanisms.
