Modular Power Supply System Docking USB Type-C Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing power transmission capabilities of USB Type-C connectors, up to 100 W, require redesigning power supply apparatuses, leading to higher manufacturing costs and unnecessary expenses for users who do not use USB Type-C peripheral devices, as existing solutions fail to efficiently manage power transmission for these devices.
Innovation Solution
A modular power supplying system comprising a power module and a power supplying apparatus that can be docked together, using USB Type-C connectors to supply power to external devices, allowing selective support of additional functions only for USB Type-C peripheral devices, thereby reducing the need for built-in power supplies in devices and minimizing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the power supply apparatus is designed to support USB Type-C power transmission (up to 100 W), then the power transmission capability is improved, but the manufacturing cost increases
Solution Approach 1:
The power supply system is divided into two separate modules: a basic power supply apparatus and a USB Type-C power module. The power supply apparatus provides standard power output, while the USB Type-C power module adds high-power transmission capability (up to 100W) through a separate dockable unit with USB Type-C connectors. This segmentation allows manufacturers to produce the basic power supply apparatus at lower cost, and only add the expensive USB Type-C module when high-power transmission is actually needed.
2Adaptability or versatility
If the power supply apparatus is designed with USB Type-C power transmission capability, then the adaptability to USB Type-C devices is improved, but the device complexity increases
Solution Approach 1:
The system separates the basic power supply functions from the USB Type-C interface functions into distinct modules. The power supply apparatus maintains simple structure for standard power delivery, while the USB Type-C power module contains the complex USB Type-C connectors and high-power transmission circuitry. This segmentation reduces the complexity of the main power supply apparatus while maintaining adaptability to USB Type-C devices through the optional module.
3Adaptability or versatility
If users purchase a power supply apparatus with USB Type-C capability, then the versatility is improved, but the loss of money increases for users who do not need this function
Solution Approach 1:
The modular design allows users to purchase only the basic power supply apparatus at a lower price point if they only need standard power delivery. The USB Type-C power module with high-power transmission capability (up to 100W) is available as an optional add-on for users who specifically need to power USB Type-C peripheral devices. This eliminates the need for users to pay for unnecessary USB Type-C functionality, reducing unnecessary expense while maintaining versatility for those who need it.
4Adaptability or versatility
If the power supply apparatus integrates USB Type-C power transmission, then the functionality is improved, but the volume increases
Solution Approach 1:
The basic power supply apparatus is designed with compact dimensions, while the USB Type-C power module with high-power transmission capability is a separate dockable unit. When the USB Type-C module is not needed, users can use only the compact basic power supply apparatus. When high-power USB Type-C transmission is required, the module can be docked to the power supply apparatus. This segmentation allows the basic unit to maintain small volume while the extended functionality is available when needed.
