Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing storage devices face challenges in efficiently storing temperature log information due to the large size of the data generated from frequent temperature changes, which can lead to memory overflow and reduced performance.
Innovation Solution
A storage device with a controller that determines a temperature storage level based on the temperature change amount over time and stores temperature log information in designated log memory blocks according to this level, thereby optimizing storage efficiency.

Engineering Contradiction Analysis
1Reliability
If temperature log information is stored whenever the temperature changes, then the temperature monitoring completeness is improved, but the memory size required increases excessively
Solution Approach 1:
The patent combines multiple temperature log entries into a single compressed record when the temperature returns to a previously logged value. Instead of storing every temperature change event separately, the system merges subsequent identical temperature readings into the existing log entry, thereby reducing the total number of stored records while maintaining complete temperature monitoring coverage.
Solution Approach 2:
The patent discards redundant temperature log information that can be inferred from existing records. When the temperature returns to a previously logged value, the system determines that intermediate temperature logs are unnecessary and can be discarded, recovering memory space while preserving the ability to reconstruct the complete temperature history through the stored key log entries.
2Measurement precision
If temperature log information is stored frequently, then the temperature change detection accuracy is improved, but the storage efficiency deteriorates
Solution Approach 1:
The patent merges redundant temperature log entries by identifying when the temperature returns to a previously recorded value. This combining approach maintains accurate temperature change detection by preserving the key log entries that define temperature transitions, while eliminating redundant intermediate records that would otherwise reduce storage efficiency.
Solution Approach 2:
The patent extracts and retains only the essential temperature log information needed for accurate temperature change detection. By identifying and storing only the critical log entries that represent actual temperature transitions (when temperature increases or decreases to a new level), the system maintains measurement precision while removing unnecessary data that would hinder storage efficiency.

AI summary
A storage device may store temperature log information in one or more log memory blocks according to a temperature storage level and determine the temperature storage level based on a temperature change amount over time of a temperature of the storage device. By storing the temperature log information less frequently when smaller changes in the temperature are expected than when larger changes are, efficiency of storing the temperature log information may be improved.
