Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple storage devices are used to handle data with different characteristics (high-bandwidth and high-reliability), then data handling capability is improved, but system size increases and throughput decreases
Solution Approach 1:
The storage device is designed to perform multiple functions by supporting both high-bandwidth and high-reliability data handling modes within a single device. The device can dynamically switch between these modes based on the characteristics of the data being processed, eliminating the need for separate specialized storage devices for different data types.
Solution Approach 2:
The storage device incorporates dynamic mode switching capability, allowing it to adapt its operational characteristics based on real-time data requirements. The device can transition between high-bandwidth mode and high-reliability mode as needed, providing flexible adaptation to different data handling scenarios without requiring multiple fixed-function devices.
2Adaptability or versatility
If multiple storage devices are used to handle data with different characteristics, then data handling capability is improved, but system performance decreases
Solution Approach 1:
The patent combines the functionality of multiple specialized storage devices into a single unified storage device. By merging high-bandwidth and high-reliability data handling capabilities into one device with shared resources and coordinated operation, the system achieves improved throughput compared to having multiple separate devices that would introduce additional interface overhead and coordination complexity.
3Device complexity
If a single storage device is used, then system size is reduced, but the ability to handle data with different characteristics is limited
Solution Approach 1:
The storage device is segmented into different operational modes or functional units that can be activated based on data characteristics. The device internally divides its operations into high-bandwidth mode handling and high-reliability mode handling, allowing it to process different types of data appropriately while maintaining a unified physical structure and reducing overall system size.

AI summary
A smart vehicle system is disclosed, which relates to technology for increasing efficiency of a vehicle-embedded memory. The smart vehicle system includes a host and a storage device. The host selects any one of a first mode and a second mode according to operation, process or workload of a vehicle, and transmits and receives data through different channels in response to the first mode and the second mode. The storage device stores the data received through different channels in the first core circuit and the second core circuit, or reads the data stored in the first core circuit and the second core circuit. The storage device executes different operations in the first mode and the second mode in a manner that an operation to be executed in the first mode is different from an operation to be executed in the second mode.
