Three-in-one Multimedia Cable for Electronic Drawing Board
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of multiple cables (HDMI, power supply, and USB) for electronic drawing boards is inconvenient, particularly for mobile tools where space and portability are considerations.
Innovation Solution
A three-in-one multimedia cable integrating a USB-type-C plug, an HDMI plug, and a USB-type-A plug, along with a power supply plug, which allows for simultaneous video data transmission, data control, and power supply through a single USB-type-C connection, utilizing an adapter plate and an analog switch for automatic connection switching based on plug insertion direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cables (HDMI, power supply, USB) are used to connect electronic drawing board to computer, then video data transmission, power supply, and data control functions are achieved, but the complexity of connection and portability are reduced
Solution Approach 1:
The patent combines HDMI, USB, and power supply functions into a single USB Type-C cable. The cable integrates multiple pin groups that can simultaneously transmit video data, data control signals, and power, eliminating the need for separate HDMI cable, USB cable, and power supply cable.
Solution Approach 2:
The USB Type-C interface is designed to perform multiple functions through different pin group configurations. The same physical interface and cable can handle video data transmission, data control, and power supply operations, making the cable multi-functional and replacing multiple specialized cables.
2Ease of operation
If multiple cables are used for electronic drawing board connection, then all necessary functions are provided, but the convenience of use for mobile tools is reduced
Solution Approach 1:
Multiple separate cables are merged into a single integrated USB Type-C cable that provides video data transmission, data control, and power supply functions simultaneously, reducing the number of cables from three to one.
Solution Approach 2:
The USB Type-C cable is designed as a universal solution that can replace HDMI cable, USB cable, and power supply cable through its multi-functional pin groups, simplifying the connection process for mobile electronic drawing boards.
