Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple charging terminals (USB terminal and DC power terminal) are installed to support battery module and DC power module simultaneously, then the electronic device can support multiple charging modes, but the component cost, design complexity, and housing size increase
Solution Approach 1:
The USB terminal is designed to perform multiple functions: it can provide USB power charging mode and also serve as a DC power terminal through voltage transformation. The interface module detects the external power source type and transforms the power accordingly, allowing a single terminal to replace what would traditionally require two separate terminals, thus reducing device complexity while maintaining multi-mode charging capability
Solution Approach 2:
The interface module changes the voltage parameter of the power received from the USB terminal through transformation. When DC power is provided via USB, the interface module transforms the USB voltage to the appropriate DC voltage level, enabling the same physical terminal to support different charging modes by dynamically changing electrical parameters rather than requiring separate hardware terminals
2Adaptability or versatility
If multiple charging terminals are installed to support different power sources, then the electronic device can charge from various external devices, but the housing size increases
Solution Approach 1:
The USB terminal serves as a universal interface that can accept both USB-powered devices and DC-powered devices. The interface module detects the power source type and appropriately transforms and routes the power, eliminating the need for separate DC power terminal hardware and reducing the housing area required for terminal configurations
Solution Approach 2:
The patent merges the functionality of USB power charging and DC power charging into a single terminal interface. The interface module combines the power reception, detection, and transformation functions to handle both power sources through one unified terminal, thereby reducing the total housing area needed for multiple separate terminals
3Adaptability or versatility
If USB terminal and DC power terminal are both installed, then the electronic device can obtain power from computer and transformer respectively, but the component cost increases
Solution Approach 1:
The USB terminal is designed as a multi-functional interface that can detect and accept both USB power and DC power from external sources. The interface module provides universal power adaptation by detecting the power source type and transforming the voltage appropriately, eliminating the need to manufacture and install two separate physical terminals, thus reducing component costs while maintaining support for both computer and transformer power sources
Solution Approach 2:
The interface module acts as an intermediary between the USB terminal and the power management system. It detects the external power source type and transforms the power accordingly, serving as a mediator that allows a single USB terminal to interface with both USB-powered devices and DC-powered devices, thereby reducing the need for multiple specialized terminals and associated components

AI summary
An electronic device with several charging modes includes a transmission module, a central control module, an interface module, and a power module. The transmission module includes a first connecting terminal for connecting an external electronic product and produces a corresponding identification signal according to each external electronic product. The central control module supplies different power supplies to each external electronic product and produces a corresponding power setting signal. The interface module obtains a different power supply for each external electronic product through the transmitting module and converts each different power supply into a same charging power according to the power setting signal and identification signal. The power is stored in the power module to charge the power module, so that the electronic device just needs a transmitting module to obtain the power from any external electronic product, and thus greatly improve the convenience of charging the electronic device.
