Parallel Charging Circuits for Mobile Battery Fast Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fast charging solutions for mobile electronic devices require a large power adapter, which is inconvenient for users who need to charge their devices quickly in situations like travel, as they must carry a bulky adapter.
Innovation Solution
The implementation of two separate charging circuits and ports in an electronic device that can detect and utilize multiple plugs for parallel charging, prioritizing a primary adapter for system power and supplementing with a secondary adapter for faster battery charging without powering the system.

Engineering Contradiction Analysis
1Productivity
If a single large power adapter is used for fast charging, then charging speed is improved, but adapter size and portability deteriorate
Solution Approach 1:
The charging system is divided into multiple independent charging circuits (first charging circuit and second charging circuit) that can operate separately or together. Each circuit has its own power adapter input, allowing the charging function to be segmented across multiple smaller adapters rather than requiring one large adapter.
Solution Approach 2:
Multiple charging circuits are combined to work together on a single battery. The system can merge the charging capacity of multiple smaller adapters by routing power through separate charging circuits that converge at the battery charging interface, achieving fast charging without needing a single large adapter.
2Productivity
If multiple charging circuits are added to enable parallel charging, then charging speed is improved, but device complexity increases
Solution Approach 1:
The charging circuits are designed to be multi-functional: they can operate independently for standard charging or combine for fast charging. The system provides universal charging capability that adapts to different adapter configurations (single adapter in either port, or multiple adapters in both ports) without requiring completely separate charging paths.
Solution Approach 2:
The system includes automatic detection and routing capabilities that allow the charging circuits to self-configure based on which adapters are connected. The controller automatically detects the presence of adapters in different ports and routes power appropriately, eliminating the need for complex manual configuration or switching mechanisms.
