Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate compressor and encryptor devices are used, then data compression and encryption functions are provided, but system complexity and cost increase
Solution Approach 1:
The patent combines the compressor and encryptor functions into a single integrated device that can perform both data compression and encryption operations. This single device includes a processor that can execute compression algorithms and encryption algorithms sequentially, eliminating the need for separate physical devices and reducing system complexity while maintaining both functionality.
Solution Approach 2:
The integrated device is designed with a universal processor capable of performing multiple functions - data compression using various algorithms (e.g., Lempel-Ziv, Huffman coding) and data encryption using cryptographic algorithms (e.g., AES, DES). This multi-functional approach allows one device to replace multiple specialized devices.
2Adaptability or versatility
If separate compressor and encryptor devices are used, then data compression and encryption functions are provided, but system cost increases
Solution Approach 1:
By merging the compressor and encryptor into a single integrated device with shared hardware resources (processor, memory, interfaces), the patent reduces the total cost of the system. The shared components eliminate duplicate investments in separate devices, reducing overall manufacturing and deployment costs while maintaining both compression and encryption capabilities.
3Adaptability or versatility
If data is routed through two separate devices, then compression and encryption are performed, but transmission line losses and delays increase
Solution Approach 1:
The patent integrates the compression and encryption functions within a single device, allowing data to be processed internally without being transmitted through external cables or interfaces between separate devices. This eliminates transmission line losses, delays, and noise/jitter problems that occur when data is routed through multiple separate devices, thereby improving data quality and reliability.
4Adaptability or versatility
If multiple devices are used, then comprehensive data processing is achieved, but training and management requirements increase
Solution Approach 1:
The integrated device consolidates multiple functions (compression, encryption, and potentially protocol conversion) into a single unit with unified management interfaces. This reduces the number of separate devices that need to be configured, monitored, and maintained, thereby reducing training requirements for operators and simplifying overall system management while maintaining comprehensive data processing capability.
Data Source
AI summary
A network interface includes at least one physical memory, at least one client port, at least one processor accessing the at least one physical memory, and at least one network port. The client port receives data blocks which contain a quantity of bits from at least one first client computer system. The processor temporarily stores the data blocks in the at least one physical memory. The processor interacts with the physical memory and compresses the data blocks to reduce the quantity of bits. The processor further interacts with the physical memory such that the compressed data blocks are encrypted to produce encrypted frames. The at least one network port transmits the encrypted frames across a communication network.
