Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature is measured using a separate request command from the controller, then temperature information can be obtained, but it increases operation commands and may cause measurement delays
Solution Approach 1:
The patent combines temperature measurement with normal operation execution by having the nonvolatile memory device automatically measure temperature during its operation and include the temperature information in the operation result response. This eliminates the need for separate temperature measurement commands, thereby reducing operation overhead and measurement time while maintaining accurate temperature monitoring.
Solution Approach 2:
The nonvolatile memory device performs self-measurement of its own temperature during operation and autonomously includes this information in its response to the controller. This self-service approach eliminates the need for external temperature measurement requests, reducing communication overhead and enabling continuous temperature monitoring without additional time loss.
2Measurement precision
If temperature sensor is integrated in the nonvolatile memory device, then temperature measurement precision is improved, but device complexity increases
Solution Approach 1:
The temperature sensor is integrated directly into the nonvolatile memory device structure, merging the temperature measurement function with the existing memory device. This eliminates the need for external temperature sensors and complex communication protocols, reducing overall system complexity while achieving precise internal temperature measurement.
3Productivity
If temperature information is transmitted with operation results, then temperature monitoring efficiency is improved, but communication overhead increases
Solution Approach 1:
The patent merges temperature information transmission with the existing operation result response protocol. The temperature data is included within the same communication packet as the operation result, utilizing existing communication channels and protocols. This approach improves temperature monitoring efficiency by enabling continuous monitoring without additional communication overhead, as the temperature data travels alongside necessary operation feedback.
