Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power-saving techniques for electrical equipment often result in increased power consumption due to inefficient mode switching between ordinary and power-saving modes, leading to performance degradation and unintended high power usage.
Innovation Solution
A power-saving processing unit that manages information on mode switching, predicts time durations for mode changes, and decides whether to switch based on calculated continuation periods and power consumption data, ensuring optimal mode transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If power-saving mode is activated to reduce power consumption, then power consumption is reduced during operation, but power consumption increases due to overhead processing for mode switching
Solution Approach 1:
The system performs preliminary prediction of the duration that power-saving mode will be maintained before actually switching modes. The prediction unit estimates how long the power-saving mode can be effectively used, and this prediction informs the decision on whether to switch modes, ensuring that the overhead switching cost will be justified by sufficient subsequent power-saving operation time
Solution Approach 2:
The system uses feedback from the prediction unit about expected power-saving duration to dynamically control mode switching decisions. The control unit receives prediction results and adjusts switching behavior accordingly, creating a closed-loop system that adapts to actual power-saving opportunities and avoids unnecessary mode transitions that would waste energy
2Adaptability or versatility
If mode switching is performed frequently to adapt to usage changes, then adaptability improves, but response delay increases due to processing overhead
Solution Approach 1:
The system performs preliminary prediction of power-saving mode duration before executing mode switching. This advance prediction allows the system to plan mode transitions strategically, avoiding frequent unnecessary switches and reducing the overall time lost to mode transition overhead while maintaining adaptability to actual usage patterns
3Use of energy by stationary object
If power-saving processing is applied to many apparatus elements, then power consumption during operation is reduced, but power consumption increases during switching processing
Solution Approach 1:
The system extracts and separately manages the prediction function from the mode switching control. The prediction unit independently evaluates power-saving opportunities and provides recommendations, allowing the control unit to make informed decisions without being overwhelmed by complex switching logic. This separation simplifies the overall control architecture while enabling sophisticated power-management strategies

AI summary
A power-saving processing unit is provided which is capable of realizing proper mode switching by taking into account a power consumption as well in a shift processing and a return processing for switching an operation mode. In a power-consumption information table 170, there are recorded a power consumption (mJ) which is required for a processing for shifting into a power-saving mode, a consumed power (mW) when an operation is executed in the power-saving mode and a power consumption (mJ) which is required for a processing for returning to an ordinary mode. A time prediction section 102 refers to a timer-list management queue 201 and predicts a period of time until the power-saving mode is removed. On the basis of the power-consumption information table 170 and the predicted time, a mode-switching decision section 103 compares a power consumption (mJ) when switching is executed into the power-saving mode and a power consumption (mJ) when the switching is not executed, and only if the former is far less than the latter, decides that switching should be executed into the power-saving mode.
