Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing use of multiple portable electronic devices by users poses a challenge in managing battery power efficiently, as these devices often have short battery service cycles and redundant functionalities, leading to unnecessary battery consumption and potential device shutdown during activities like running or outdoor events.
Innovation Solution
A system that coordinates power management across mobile phones and portable communication devices, using a server to collect and analyze power data, determine power dissipation rates, and send collaborative power management commands to reduce redundancy and conserve battery life by adjusting operational modes and disabling non-essential applications or hardware components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple portable electronic devices are used simultaneously, then device functionality and user service capability are improved, but battery power consumption increases and battery service cycle decreases
Solution Approach 1:
The patent merges power management control across multiple portable devices through a centralized server system. The server collects power status information from multiple devices and coordinates their power consumption, allowing devices to share power management responsibilities and reduce redundant power usage while maintaining enhanced functionality.
Solution Approach 2:
The server system provides universal power management capabilities that can be applied across different types of portable devices (mobile phones, tablets, laptops, wearables). This multi-functional approach allows the system to optimize power consumption for various device types simultaneously, reducing overall energy usage while preserving device-specific functionalities.
2Adaptability or versatility
If multiple portable electronic devices are used simultaneously, then service capability is improved, but battery service cycle decreases
Solution Approach 1:
The system performs preliminary power management actions by predicting future power needs based on current device states and usage patterns. The server proactively adjusts power consumption settings before battery depletion occurs, extending the battery service cycle while maintaining service capability through advance coordination.
Solution Approach 2:
The patent implements a feedback mechanism where devices continuously report their power status to the server, which then adjusts power management strategies in real-time. This closed-loop system monitors battery levels and service capabilities, dynamically optimizing the balance between maintaining service functionality and extending battery duration across multiple devices.
3Reliability
If redundant functionalities are maintained across devices, then service reliability is improved, but unnecessary battery consumption occurs
Solution Approach 1:
The system extracts and centralizes redundant functionality management at the server level. Instead of each device independently maintaining redundant capabilities, the server identifies and coordinates shared functions across devices, eliminating unnecessary duplicate operations and reducing energy consumption while preserving service reliability through coordinated redundancy management.
4Loss of energy
If collaborative power management coordination is implemented, then power efficiency is improved, but system complexity increases
Solution Approach 1:
The patent introduces a server as an intermediary that handles the complexity of collaborative power management. Individual devices communicate their power status to the server, which performs the complex coordination and optimization calculations. This mediator approach improves power efficiency across the device ecosystem while isolating the complexity from individual devices, maintaining relative simplicity at the device level.
Data Source
AI summary
A mobile phone that coordinates power management across multiple communication devices. The mobile phone comprises a processor, a memory, long-range and short-range radio transceivers, and an application. When executed by the processor, the application receives device power reserve and device application usage information via the short-range radio transceiver from a portable communication device, and transmits the device power reserve and device application usage information, a phone power reserve and a phone application usage information via the long-range radio transceiver to a server computer. The application further receives power management instructions via the long-range radio transceiver from the server, creates a device power management command based on the power management instructions, transmits the device power management command via the short-range radio transceiver to the portable communication device, and configures the mobile phone to manage a battery power reserve of the mobile phone based on the power management instructions.
