Multi-Mode Apparatus Shift Timing for Readiness and Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power-saving technologies in apparatuses with multiple modes have reduced effectiveness due to a constant shift time to a mode with longer process readiness, which can lead to increased power consumption and reduced user convenience.
Innovation Solution
An information processing system that determines a mode based on historical process data and user behavior, adjusting shift times to balance power-saving and user convenience by recording mode transitions and optimizing shift times using a cumulative exponential distribution function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the apparatus uses a constant shift time to a mode with longer process readiness, then user convenience is improved, but power-saving effect is reduced
Solution Approach 1:
The patent applies dynamics by making the shift time variable rather than constant. The control unit dynamically adjusts the shift time based on detected usage patterns, allowing the system to adapt between power-saving and user-convenience modes. This resolves the contradiction by enabling the shift time to be short when usage is frequent (improving convenience) and long when usage is infrequent (improving power-saving effect).
Solution Approach 2:
The patent changes the parameter of shift time from a fixed constant to a variable parameter based on usage detection. By monitoring whether the apparatus is frequently used within a predetermined period, the system adjusts the shift time parameter accordingly, resolving the contradiction between constant convenience and variable power-saving needs.
2Ease of operation
If the apparatus shifts to a mode with longer process readiness more frequently, then user convenience is improved, but power consumption increases
Solution Approach 1:
The patent implements feedback by monitoring usage patterns and using this information to adjust shift time. The control unit detects whether the apparatus is frequently used within a predetermined period and adjusts the shift time accordingly, creating a feedback loop that optimizes the balance between process readiness and power consumption based on actual usage behavior.
Solution Approach 2:
The system dynamically adjusts the shift time parameter based on detected usage frequency. When usage is frequent, the shift time is reduced to improve process readiness; when usage is infrequent, the shift time is increased to reduce standby power consumption. This dynamic adjustment resolves the contradiction between readiness and power consumption.
3Speed
If the apparatus uses a shorter shift time, then responsiveness to user needs is improved, but power-saving effectiveness is reduced
Solution Approach 1:
The patent changes the shift time parameter from a fixed value to a variable based on usage detection. By monitoring usage frequency within a predetermined period, the system adjusts the shift time parameter to be short when responsiveness is needed (frequent usage) and long when power-saving is prioritized (infrequent usage), resolving the contradiction between speed and energy loss.
Solution Approach 2:
The system makes the shift time dynamic rather than static, adjusting it based on real-time usage pattern detection. This allows the apparatus to achieve short shift times (improving responsiveness) only when necessary, while maintaining long shift times (improving power-saving) during low-usage periods, thus resolving the contradiction between responsiveness and power-saving effectiveness.

AI summary
An information processing system includes a processor for an apparatus having a plurality of modes having different times until execution of a process is ready, the processor being configured to: determine a mode that is to be recorded in a history as a mode at a time of execution of a process, the determining being performed based on a mode at the time of the apparatus's execution of the process, the determining being performed also based on a detected position of a person or a moving time, the detected position being a position at a time when a human detecting sensor detects the person for the first time from a state in which the human detecting sensor does not detect any person, the moving time being a time required for the person to move from the detected position to the apparatus; record the determined mode in the history; and output a set value of a shift time elapsing until the apparatus shifts to a mode in which a time until execution of a process is ready is longer than in another mode among the plurality of modes, the outputting being performed based on a count of processes performed in a specific mode, the count of processes being obtained based on the history.
