Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for charging electronic devices are inefficient, requiring extended periods to fully charge batteries, and often rely on a single power source, limiting charging speed and flexibility.
Innovation Solution
A system that detects power levels from multiple sources, including wired and wireless options, and directs power to a charging circuit based on thresholds, allowing concurrent or sequential energy harvesting from various sources such as laser, ultrasonic, and solar energy, to optimize charging efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single power source is used for charging, then the charging system is simple, but the charging time is extended and charging speed is limited
Solution Approach 1:
The patent combines multiple power sources (wired power source and wireless power source) into a single charging system that can simultaneously charge the battery. The controller integrates power from both sources by managing power flow through switching circuits, allowing the device to accept power from either or both sources concurrently, thereby reducing overall charging time while maintaining system manageability
Solution Approach 2:
The charging system is designed to be multi-functional by accepting power from different types of sources (wired and wireless). The controller and switching circuitry enable the system to adaptively select and process power from various sources based on availability and requirements, making the charging system versatile rather than dedicated to a single power delivery method
2Productivity
If multiple power sources are used concurrently, then charging speed increases, but power management complexity increases
Solution Approach 1:
The power management system dynamically adjusts power flow distribution based on real-time conditions. The controller monitors power availability from wired and wireless sources, and actively switches between different power routing configurations. This dynamic control allows the system to optimize charging speed by utilizing both sources when available while simplifying operation when only one source is present, thereby managing complexity through adaptive behavior rather than fixed complex circuitry
3Measurement precision
If power threshold comparison is performed for each source, then power directing accuracy improves, but processing overhead increases
Solution Approach 1:
The system performs threshold comparison checks for power sources, but only to the extent necessary for effective power management. Rather than continuous monitoring and comparison at maximum precision, the controller performs threshold-based decisions that are sufficient to determine whether a power source is viable for charging. This partial action approach achieves adequate power directing accuracy without the excessive processing overhead of continuous high-precision measurement and comparison

AI summary
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus detects a level of power received from each of a plurality of sources. The apparatus directs the power received from a first source to a charging circuit and directs the power received from at least a second source to the charging circuit. The apparatus directs the power received from the first source to the charging circuit by comparing the detected level of the power with a threshold and directing the power to the charging circuit based on a result of the comparison. The apparatus directs the power received from the at least a second source to the charging circuit by comparing the detected level of the power with the threshold and directing the power to the charging circuit based on a result of the comparison.
