Dynamic Power Saving Transition Time Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The convenience of users is compromised when the time until an apparatus transitions to a power saving state is constant, as it does not account for varying processing intervals over days or weeks, leading to inconsistent user experience.
Innovation Solution
An information processing apparatus calculates a set value for the transition time to a power saving state based on a history of processing intervals and a target return time, allowing for dynamic adjustment of the transition time to improve user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a constant time is set for transition to power saving state, then the apparatus can maintain simple control logic, but user convenience deteriorates due to varying processing intervals
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed, constant transition time to a dynamic, variable transition time that adapts to actual usage patterns. The control logic automatically adjusts the transition time based on detected processing intervals and usage history, making the system responsive to changing user needs while maintaining operational simplicity.
Solution Approach 2:
The patent implements feedback by continuously monitoring the actual usage pattern and processing intervals, then using this information to adjust the transition time to power saving state. The system detects whether the apparatus is being used within the transition period and modifies future transition times accordingly, creating a closed-loop control system that improves user convenience without increasing perceived complexity.
2Ease of operation
If transition time to power saving state is extended, then user convenience improves by reducing waiting time, but energy consumption increases
Solution Approach 1:
The patent applies partial action by extending the transition time only when necessary, based on detected usage patterns. Rather than maintaining a constantly long transition time that would waste energy, the system selectively extends the transition period only when usage indicates it will be needed, achieving user convenience improvements without proportional energy penalties.
Solution Approach 2:
The patent changes the transition time parameter dynamically based on usage conditions. The system monitors processing intervals and adjusts the transition time parameter to optimize the balance between user convenience and energy consumption, transitioning from a static parameter to a condition-dependent variable parameter.
3Use of energy by moving object
If transition time is shortened to save energy, then energy consumption decreases, but user waiting time increases reducing convenience
Solution Approach 1:
The patent applies preliminary action by preparing the apparatus for potential extended operation in advance. When usage patterns indicate upcoming processing activities, the system proactively extends the transition time before the user actually needs the apparatus, preventing waiting time issues before they occur while maintaining energy efficiency during low-usage periods.

AI summary
An information processing apparatus includes a processor configured to output a set value of a transition time until an apparatus transitions to a power saving state, which is obtained based on a first history of a time interval of each processing executed by the apparatus and a target value of a return time required until the apparatus returns from the power saving state.
