Power Delivery Control Module for Adapter Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The incompatibility of power adapters across different manufacturers leads to resource wastage and environmental harm, as consumers need separate adapters for various devices, and the transition to USB Type-C/USB Power Delivery does not immediately eliminate the production of new, incompatible adapters.
Innovation Solution
A power delivery control module with a first interface (non-USB) and a second USB Type-C interface, coupled with a controller, enables power transmission between incompatible devices and adapters by selectively delivering power based on a power delivery specification, utilizing a microprocessor, voltage regulating circuit, and detection circuit to achieve interoperability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manufacturers produce different types of power adapters for different devices, then device compatibility is improved, but resource wastage and environmental harm increase
Solution Approach 1:
The power adapter is designed with multiple output interfaces including both traditional interfaces (such as DC round pin, micro USB) and USB Type-C interface, allowing a single adapter to charge multiple types of devices. The controller automatically detects and switches between different output modes based on the connected device, eliminating the need for multiple specialized adapters and reducing resource wastage.
Solution Approach 2:
The controller acts as an intermediary between the power adapter and various devices, detecting the device type through communication protocols and automatically selecting the appropriate output mode. This mediator enables compatibility between different device standards without requiring separate adapters for each device type.
2Loss of substance
If USB Type-C/USB Power Delivery is promoted for uniformity, then resource wastage is reduced, but transition period produces continuous new adapter production causing environmental harm
Solution Approach 1:
The adapter merges multiple interface types (traditional DC round pin, micro USB, and USB Type-C) into a single device, combining the functions of what would traditionally require separate adapters. This integration allows the system to transition toward USB Type-C uniformity while maintaining compatibility with legacy devices, reducing the need for continuous production of new specialized adapters during the transition period.
Solution Approach 2:
The adapter employs dynamic output switching capability where the controller automatically adjusts the output interface and parameters based on the detected device type. This dynamic adaptation allows the same physical adapter to function across different standards, reducing the complexity of having multiple static adapter types during the transition period.
3Adaptability or versatility
If consumers purchase multiple power adapters for different devices, then device compatibility is ensured, but cost and convenience are reduced
Solution Approach 1:
The power adapter provides universal compatibility across multiple device types by incorporating various output interfaces (DC round pin, micro USB, USB Type-C) and automatically detecting the connected device. Users only need to carry one adapter instead of multiple device-specific adapters, significantly improving convenience while maintaining full compatibility.
Solution Approach 2:
The adapter incorporates automatic device detection and output switching functionality through its controller, which autonomously identifies the connected device type and selects the appropriate output mode without user intervention. This self-service capability eliminates the need for users to manually configure or remember which adapter to use for which device.

AI summary
A power delivery control module includes a first interface, a second interface and a controller. The first interface is configured to be coupled with a first external device. The second interface is configured to be coupled with a second external device. The second interface is a USB Type-C interface, and the first interface is not a USB Type-C interface. The controller is coupled with the first interface and the second interface. Wherein when the first interface is coupled with the first external device and the second interface is coupled with the second external device, the power delivery control module selectively transfers power from the first external device to the second external device or from the second external device to the first external device.
