Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual replacement of software drivers and hardware components is performed to match different storage protocols, then protocol compatibility is improved, but device complexity and operation time increase
Solution Approach 1:
The patent implements a universal test apparatus that can handle multiple storage protocols (SATA, SAS, PCIe, NVLink, CXL, etc.) through a single integrated system. The apparatus includes multiple protocol-specific hardware units (SATA controller, SAS controller, PCIe controller, NVLink controller, CXL controller) and software units that can be dynamically activated based on the storage device being tested. This multi-functional design eliminates the need for manual hardware replacement while maintaining broad protocol compatibility.
Solution Approach 2:
The system dynamically switches between different protocol configurations based on the detected storage device type. The control unit automatically selects and activates the appropriate hardware and software units corresponding to the protocol of the connected storage device. This dynamic adaptation allows the apparatus to transform its functional state without physical reconfiguration, resolving the contradiction between versatility and complexity.
2Adaptability or versatility
If manual replacement of software drivers and hardware components is performed to match different storage protocols, then protocol compatibility is improved, but operation time and productivity decrease
Solution Approach 1:
The test apparatus performs self-configuration by automatically detecting the protocol type of the connected storage device and activating the corresponding hardware and software units. The control unit manages the entire switching process without human intervention, allowing the system to serve itself in adapting to different protocols. This eliminates manual configuration time and significantly improves testing productivity while maintaining protocol compatibility.
Solution Approach 2:
All necessary hardware units and software units for multiple protocols are pre-configured and ready within the apparatus before testing begins. The system has all potential protocol handlers available in advance, allowing instant activation based on device detection. This preliminary preparation eliminates the need for manual setup or replacement during testing, thereby improving productivity.
3Adaptability or versatility
If multiple test apparatuses are used to test different storage protocols, then protocol compatibility is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges multiple protocol-specific test functions into a single integrated apparatus. Instead of using separate test devices for SATA, SAS, PCIe, NVLink, and CXL protocols, the system combines all these capabilities in one unified platform. The control unit coordinates multiple hardware units and software units within a single system, reducing the number of separate devices needed while maintaining the ability to test all protocol types.
4Adaptability or versatility
If protocol switching is performed manually, then protocol compatibility is improved, but operation time and ease of operation worsen
Solution Approach 1:
The system automatically performs protocol switching without requiring user intervention. When a storage device is connected, the control unit detects the protocol type and autonomously activates the corresponding hardware and software units. This self-service capability eliminates the need for operators to manually configure protocols, significantly improving ease of operation while maintaining protocol compatibility.
Solution Approach 2:
The system uses feedback from device detection to automatically adjust its configuration. The control unit receives information about the connected storage device's protocol type and uses this feedback to select the appropriate hardware and software units. This closed-loop control ensures the correct protocol configuration is applied without manual input, making operation simple while maintaining compatibility.
