Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single heat generation control equation is used for all power modes, then the control system is simple, but heat generation cannot be efficiently controlled across different operating conditions
Solution Approach 1:
The patent applies dynamics by making the heat generation control equation adaptive rather than static. The controller dynamically switches between different heat generation control equations based on the current power mode (e.g., high power mode, low power mode, idle mode). This allows the control system to optimize heat management for each specific operating condition, resolving the contradiction between system simplicity and control effectiveness.
Solution Approach 2:
The patent changes the parameter of the control equation based on power mode. Different heat generation control equations are selected according to the operating state (high power, low power, idle), which adjusts the thermal threshold and control behavior to match the specific power consumption characteristics of each mode. This parameter change enables effective heat control without requiring a completely complex system.
2Ease of operation
If temperature thresholds are uniform across all power modes, then the control logic is simple, but performance degradation occurs due to inappropriate heat control
Solution Approach 1:
The patent applies local quality by tailoring temperature thresholds and control parameters to specific local conditions (power modes). Instead of using a single uniform threshold, the system implements different thermal thresholds for high power mode, low power mode, and idle mode. This localized approach ensures that each power mode has appropriate heat control parameters, preventing performance degradation while maintaining relatively simple control logic within each mode.
Solution Approach 2:
The system dynamically adjusts temperature thresholds based on the current power mode. The controller switches between different thermal threshold values corresponding to different operating states, allowing the system to optimize performance for each mode while maintaining simple control logic within each specific mode context.
3Productivity
If heat generation control is not implemented, then the storage device operates continuously at full performance, but heat accumulation causes performance degradation and potential damage
Solution Approach 1:
The patent implements feedback by continuously monitoring the temperature of the memory device and comparing it against power-mode-specific thresholds. When the temperature exceeds the threshold for the current power mode, the controller switches to a different power mode or adjusts operation to reduce heat generation. This feedback mechanism allows the system to maintain continuous operation capability while preventing harmful heat accumulation through adaptive control.
Solution Approach 2:
The system changes operational parameters (power mode, temperature thresholds) based on real-time temperature monitoring. By dynamically adjusting the power mode according to temperature feedback, the system can maintain high productivity during low-temperature periods while preventing heat accumulation damage when temperatures rise, thus resolving the contradiction between continuous operation and heat damage prevention.

AI summary
In an embodiment of the disclosed technology, a heat generation control equation used when changing a power mode for heat generation control of a component included in an electronic device such as a storage device is used by being set differently for each power mode. Therefore, heat generation control that accurately reflects the relationship between a change in temperature of the component in each power mode and a temperature value obtained through a temperature sensor may be performed. Accordingly, performance degradation due to unnecessary heat generation control may be prevented by efficient heat generation control, and operational performance of the storage device may be improved.
