Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses face challenges in accurately calculating and displaying power-saving effects, as the difference in power consumption between high and low power modes is not effectively quantified for each component, making it difficult to assess the overall power-saving impact.
Innovation Solution
The apparatus includes a power-saving control module, power consumption measuring module, power-saving effect calculation module, log storing module, and log display module to set components in power-saving states, measure power consumption, calculate power-saving effects, and display cumulative values, allowing for precise tracking and visualization of power-saving achievements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the difference in power consumption between high and low power modes is calculated to display power-saving effects, then power-saving information can be provided to users, but accurate calculation becomes difficult when multiple components with different power-saving settings are involved
Solution Approach 1:
The patent divides the power-saving effect calculation into component-level segments. Each component (CPU, HDD, display, etc.) has its own power-saving effect calculated separately based on its specific power consumption in different modes. These segmented calculations are then aggregated to provide the total system power-saving effect, enabling accurate tracking of each component's contribution.
Solution Approach 2:
The patent introduces a power-saving effect display application as an intermediary layer between the operating system and the user. This application acts as a mediator that collects power consumption data from various components, calculates power-saving effects using stored power consumption information, and presents the results in an understandable format, thereby simplifying the complex calculation process.
2Adaptability or versatility
If power-saving parameters are set for each component individually, then flexible power management is achieved, but the overall power-saving effect becomes difficult to quantify
Solution Approach 1:
The patent merges the individual power-saving effects of multiple components to calculate the total system power-saving effect. By combining the segmented calculations from each component (CPU, HDD, display, etc.), the system provides a comprehensive view of the overall power-saving achievement while maintaining the ability to view individual component contributions.
Solution Approach 2:
The patent creates a universal power-saving effect calculation system that can handle multiple components with different power-saving modes and settings. The system is designed to work with various component types (processing units, storage devices, display devices, etc.) and can calculate power-saving effects across different time periods, providing multi-functional power management capabilities.

AI summary
According to one embodiment, an information processing apparatus having a power-saving function includes a power-saving control module, a power consumption measuring module, a log accumulation module, and a log display module. The power-saving control module sets each of predetermined components in the information processing apparatus in either a normal operation state or a power-saving state, based on power-saving parameters corresponding to the predetermined components. The power consumption measuring module measures a total power amount consumed by the apparatus in a predetermined time period. The power-saving effect calculation module calculates a power-saving effect value indicative of a power amount reduced in the predetermined time period by the setting of the power-saving parameters. The log storing module stores information indicative of the total power amount and the power-saving effect value. The log display module displays cumulative values which are periodically accumulated the total power amounts and the power-saving effect values.
