Dynamic Power Mode Control for Usage-Aware Function Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing apparatuses, such as laptops, cannot freely set which functions to stop in low power consumption modes like Modern Standby, leading to increased power consumption due to improper function management based on usage status.
Innovation Solution
An information processing apparatus with a main control unit, setting information storage unit, and mode control unit that changes the low power consumption mode based on usage status, allowing specific functions to be stopped or kept active depending on detected usage status, location, time, or power source, using sensors like acceleration sensors to determine the usage status and adjust power consumption accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the information processing apparatus enters a low power consumption mode to stop some functions, then power consumption is reduced, but the ability to adapt to different usage statuses is worsened
Solution Approach 1:
The patent implements dynamic adaptability by enabling the information processing apparatus to automatically adjust which functions are stopped or maintained in the low power consumption mode based on detected usage status. The control unit detects usage status (e.g., laptop mode, tent mode, tablet mode) and dynamically determines the optimal function stoppage configuration, transforming a static power saving mode into a dynamic, usage-aware power management system that resolves the contradiction between power reduction and adaptability.
Solution Approach 2:
The patent changes the operational parameters of functions in the low power consumption mode based on usage status. By detecting usage status and adjusting which functions are stopped or maintained, the system modifies the operational state parameters of various components, enabling adaptive power management that optimizes both power consumption and functional appropriateness for different usage scenarios.
2Use of energy by moving object
If functions are stopped in low power consumption mode, then power consumption is reduced, but reliability of function availability is worsened
Solution Approach 1:
The patent dynamically changes the operational parameters of functions based on detected usage status. The control unit determines which functions should be stopped or maintained by analyzing usage status, thereby optimizing the balance between power consumption reduction and maintaining necessary function availability. This parameter-based adaptive control ensures that critical functions remain available while non-critical functions are stopped, resolving the contradiction between power saving and reliability.

AI summary
An information processing apparatus includes: a main control unit that executes processing based on an operating system (OS) and that changes to a low power consumption mode to stop some functions including a display unit while making a predetermined function work; a setting information storage unit that stores a usage status mode based on usage status and setting information in association with one another, where the setting information indicates whether to stop the predetermined function implemented by a device driver added to the OS in the low power consumption mode; a mode control unit that changes the main control unit to the low power consumption mode; and a change processing unit that changes a stopped state of the predetermined function.
