Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the storage device searches for optimal setting parameter values dynamically, then the adaptability to temperature changes is improved, but the timing margin is insufficient and the complexity increases
Solution Approach 1:
The patent pre-stores optimal setting parameter values for multiple temperature ranges in a setting parameter memory before the actual operation. When the storage device needs to operate at a specific temperature, the controller simply retrieves the pre-computed optimal parameters from memory, eliminating the need for real-time search and ensuring sufficient timing margin while maintaining adaptability to temperature changes.
2Device complexity
If the storage device uses constant setting parameter values, then the device complexity is reduced, but the manufacturing precision and adaptability to temperature variations deteriorate
Solution Approach 1:
The patent implements temperature-dependent parameter changes by storing multiple sets of setting parameters corresponding to different temperature ranges in the setting parameter memory. The controller selects the appropriate parameter set based on the current temperature, allowing the storage device to adapt to temperature variations without requiring complex real-time calculation mechanisms, thus balancing simplicity with precision.
3Adaptability or versatility
If the storage device searches for optimal setting parameters in real-time, then the adaptability is improved, but the productivity decreases due to insufficient timing margin
Solution Approach 1:
The patent performs the parameter search and selection in advance during manufacturing or initialization, storing the results in the setting parameter memory. During actual operation, the controller simply retrieves the pre-determined optimal parameters from memory, which eliminates the time-consuming real-time search process and ensures both adaptability to temperature and high operational efficiency without compromising productivity.

AI summary
A storage device may search for, upon determining that the storage device has entered a preset target state, target setting parameter values, which are values of one or more setting parameters corresponding to a current temperature, in a setting parameter memory. When the search fails, the storage device may reset values of the setting parameters corresponding to the current temperature, and may set an operating environment of the storage device based on the reset values of the setting parameters.
