Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals without communication functions cannot obtain power consumption information, and existing technologies fail to ensure execution of specific functions for a specified period of time, such as making a 5-minute call while conserving power for other tasks like browsing the Internet.
Innovation Solution
An information processing device with a power consumption calculating unit, a request generating unit, and a request processing unit that estimates battery life and power consumption of each function based on actual performance values, allowing execution of specific functions for a specified period using the remaining power without external information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile terminals obtain power consumption information from external sources (broadcast waves), then power consumption management is improved, but terminals without communication functions cannot obtain this information
Solution Approach 1:
The mobile terminal measures its own power consumption internally through a power consumption measuring unit that monitors actual power usage of each function. This self-service approach eliminates dependency on external broadcast waves or communication functions, allowing terminals without communication capabilities to still manage power consumption effectively.
Solution Approach 2:
The patent introduces an intermediary power consumption information storage unit that stores measured power consumption data locally. This intermediary mechanism allows the terminal to retain and reference power consumption information without requiring continuous external communication, bridging the gap between terminals with and without communication functions.
2Measurement precision
If the terminal estimates power consumption based on actual performance values, then power consumption accuracy is improved, but the terminal cannot ensure execution of specific functions for specified periods
Solution Approach 1:
The patent performs preliminary measurement of power consumption for each function before actual use. The power consumption measuring unit measures and stores actual power consumption data in advance, creating a reference database that enables accurate estimation during operation and supports reliable power allocation decisions for ensuring function execution.
Solution Approach 2:
The system continuously monitors actual power consumption and uses this feedback to update and refine power consumption estimates. The power consumption information is dynamically adjusted based on measured values, allowing the terminal to accurately predict remaining battery life and reliably determine when specific functions can be executed within power constraints.
3Adaptability or versatility
If the terminal calculates power consumption for each function, then power management flexibility is improved, but device complexity increases
Solution Approach 1:
The patent segments the power consumption measurement and management system into distinct functional units: a power consumption measuring unit for each function, a power consumption information storage unit, and a power consumption calculating unit. This segmentation allows each component to handle specific tasks independently, managing complexity while providing flexible power management for multiple functions.
Data Source
AI summary
An information processing device and a mobile terminal include a power consumption calculator which calculates, for each processing executed by the information processing device (or mobile terminal), power consumption information concerning an amount of power consumed by executing each processing. A request generator compares the amount of power indicated by the power consumption information and a remaining amount of power of the information processing device(or mobile terminal), and generates a request to execute predetermined processing according to a result of the comparison. A request processor executes the predetermined processing in response to the generated request.
