Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate 2.5-inch hard disks are used for independent operations, then independent storage functionality is achieved, but the total product size becomes large and compatibility issues arise due to different communication protocols
Solution Approach 1:
The patent combines two independent storage units into a single integrated device with a unified housing and shared circuit board. The first and second storage units are mounted on the same circuit board, which provides independent electrical connectors for each unit, allowing them to function independently while occupying a single 2.5-inch form factor space.
Solution Approach 2:
The circuit board is designed with multiple electrical connectors that support different communication protocols (SATA and PCIe). This allows the integrated storage device to accommodate storage units with different protocol requirements, providing multi-functionality and protocol compatibility within a single device.
2Adaptability or versatility
If two separate hard disks with different communication protocols are used, then specific functions can be performed, but compatibility issues prevent reliable operation
Solution Approach 1:
The circuit board incorporates multiple electrical connectors designed to support different communication protocols including SATA and PCIe. This universal connector design allows the device to accept storage units with various protocol types while maintaining reliable communication through protocol-appropriate connection interfaces.
3Volume of moving object
If two independent storage units are integrated into a single device, then product volume is reduced and application range is enhanced, but device complexity increases
Solution Approach 1:
The patent integrates two storage units into a single housing with a shared circuit board, reducing the overall product volume to fit within one 2.5-inch form factor. The circuit board serves as a common platform that provides electrical connections, mounting structures, and protocol compatibility for both storage units simultaneously.
4Adaptability or versatility
If a single storage device supports multiple communication protocols, then application range is enhanced, but the device structure becomes more complex
Solution Approach 1:
The electrical connectors on the circuit board are designed with universal compatibility to support multiple communication protocols including SATA and PCIe. This allows the same connector design to interface with different protocol types, providing protocol versatility without requiring separate specialized connectors for each protocol.
