Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple devices are connected via USB-C, determining how to distribute charging power between them can be challenging, especially with limited power sources, as existing technologies lack an efficient method to automatically determine and implement optimal charging schemes without manual priority settings.
Innovation Solution
An intelligent application identifies connectivity and characteristics of user apparatuses, obtains charging preference data, and determines a charging scheme based on apparatus characteristics and user input to efficiently distribute charging power via the USB-C connection, allowing devices to share energy effectively.

Engineering Contradiction Analysis
1Productivity
If multiple devices are connected via USB-C to a limited power source, then the ability to charge multiple devices simultaneously is improved, but the difficulty of determining optimal power distribution increases
Solution Approach 1:
The system enables devices to automatically negotiate and determine their own charging priorities through the intelligent application, which reads device characteristics and user preferences to autonomously allocate power without manual intervention. This self-service mechanism resolves the complexity by allowing the system to self-organize power distribution based on embedded device information.
Solution Approach 2:
The intelligent application dynamically adjusts charging parameters (power allocation, charging rate) based on real-time device characteristics and user preferences. By changing these parameters automatically, the system optimizes power distribution across multiple devices connected to a limited power source, improving charging efficiency while maintaining simplicity for the user.
2Measurement precision
If manual priority settings are required for power distribution, then charging control precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically reads device characteristics and user preferences from the devices themselves, eliminating the need for manual priority settings. The intelligent application autonomously determines optimal power distribution by processing device information and preference data, achieving both precise control and ease of operation.
Solution Approach 2:
The system continuously monitors device characteristics and user preferences to dynamically adjust power distribution. This feedback mechanism ensures precise power allocation while maintaining operational simplicity, as the system adapts automatically based on real-time information from connected devices.
3Ease of operation
If automatic charging scheme determination is implemented, then ease of operation is improved, but loss of information about user preferences increases
Solution Approach 1:
The system pre-reads and stores user preferences and device characteristics before charging begins. By obtaining this information in advance through the intelligent application, the system maintains ease of operation while preserving critical user preference data for automatic decision-making during the charging process.
Solution Approach 2:
The system continuously references stored user preferences and device information to make real-time charging decisions. This feedback loop ensures that automatic operation is maintained while user preference information is preserved and actively used to guide power distribution throughout the charging process.
