Solution Overview
Problem
Current USB charging solutions are limited by their inability to efficiently charge multiple devices simultaneously with high current capacity while ensuring safety and compactness, often requiring multiple transformers and circuits, which increases cost and complexity.
Innovation Solution
A universal module design for USB charging ports that incorporates a single circuit with a transformer or inverter to convert AC to DC, capable of delivering 1.0 to 5 Amps, integrated into desktop items like LED lights, which can charge various devices without additional safety certifications, using Type A, Type C, or custom pins for compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple transformers and circuits are used to charge multiple devices simultaneously with high current capacity, then charging capability is improved, but device complexity and production cost increase
Solution Approach 1:
The patent combines multiple USB charging ports (Type-A and Type-C) and AC outlet ports into a single integrated circuit board assembly. This unified design allows multiple devices to be charged simultaneously through shared power delivery infrastructure, eliminating the need for separate transformers and circuits for each port type, thereby reducing overall system complexity while maintaining high charging capability.
Solution Approach 2:
The circuit board assembly is designed to support multiple functions including USB Type-A charging, USB Type-C charging, and AC outlet power delivery, all through a single universal power management system. This multi-functional design enables the desktop item to serve as a comprehensive charging station without requiring separate dedicated circuits for each function.
2Reliability
If multiple transformers and circuits are used to ensure safety for high current charging, then safety is improved, but manufacturing cost increases
Solution Approach 1:
The patent integrates safety management functions into a single circuit board assembly that controls power distribution across all ports (USB Type-A, USB Type-C, and AC outlets). This consolidated approach reduces the total number of safety-critical components compared to having separate transformers and circuits for each port, thereby lowering manufacturing costs while maintaining comprehensive safety through centralized monitoring and control.
3Ease of manufacture
If a universal module design is used to simplify safety certifications, then ease of manufacture is improved, but adaptability to different device types may be reduced
Solution Approach 1:
The universal module design incorporates multiple port types (USB Type-A, USB Type-C, and AC outlets) within a single certified circuit board assembly. This approach maintains adaptability to different device types by providing diverse connection options while simplifying the safety certification process, as the entire multi-functional assembly can be certified as a unified system rather than requiring separate certifications for each port type.
Solution Approach 2:
The circuit board assembly employs dynamic power management capabilities that allow it to adaptively allocate power and adjust charging parameters based on the connected device type and requirements. This dynamic responsiveness enables the universal module to maintain high compatibility with various devices while preserving the benefits of a single certified design.
