Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If firmware code is loaded at runtime to execute additional control operations, then the memory device can perform complex control functions, but the overall performance is reduced due to loading overhead
Solution Approach 1:
The patent applies preliminary action by pre-loading the auxiliary setting management table during the initialization phase of the memory device, so that all necessary control parameters and settings are prepared in advance. This eliminates the need to load firmware code at runtime, as the hardware control circuit can directly access the pre-loaded table to perform complex control functions, thereby maintaining both adaptability and performance.
2Reliability
If firmware code is loaded at runtime to correct problems, then operational issues can be addressed, but side effects are introduced that may cause new problems
Solution Approach 1:
The patent uses copying by creating a static auxiliary setting management table that contains all necessary control parameters and settings. Instead of dynamically loading and executing firmware code that may have side effects, the system copies the required settings from the pre-loaded table into the hardware control circuit's storage unit, enabling problem correction through direct parameter application without the harmful side effects of runtime firmware execution.
3Adaptability or versatility
If additional firmware code is loaded to enhance memory device features, then functionality is improved, but the complexity of control operations increases
Solution Approach 1:
The patent applies the extraction principle by separating the control parameters and settings from the firmware code execution process. The auxiliary setting management table extracts all necessary configuration data into a structured format that the hardware control circuit can directly utilize. This eliminates the complexity of firmware loading and execution while maintaining enhanced functionality, as the hardware circuit simply reads from the pre-organized table rather than interpreting complex firmware instructions.
