Multifunctional Docking Station With Virtual Display Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing docking stations require repeated unplugging and plugging of video transmission lines for privacy protection during screen projection, leading to port damage and poor human-computer interaction.
Innovation Solution
A multifunctional docking station with a function control module and control buttons for controlling screen projection content without unplugging, combined with additional interfaces for extended functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the video transmission line is unplugged and reconnected for privacy protection during screen projection, then privacy can be protected, but the port suffers from excessive plugging and unplugging leading to damage
Solution Approach 1:
The patent extracts the video signal transmission function from the physical HDMI connection by introducing a virtual display interface. The virtual display can be enabled or disabled through software control without physically disconnecting the HDMI cable, thus separating the privacy protection function from the physical connection action. This resolves the contradiction by allowing privacy protection (extracting video output to virtual display) without the harmful repeated plugging and unplugging of the port.
2Adaptability or versatility
If the HDMI interface is unplugged for screen projection interruption, then screen projection can be stopped, but repeated plugging and unplugging causes port damage
Solution Approach 1:
The patent replaces the mechanical HDMI unplugging action with a software-based virtual display switching mechanism. The function control module receives instructions to enable or disable the virtual display, which dynamically switches video output between the physical HDMI interface and the virtual display through software control. This substitutes the mechanical plugging/unplugging system with an electronic/software-based control system, eliminating mechanical wear while maintaining projection control flexibility.
3Reliability
If the video transmission line is repeatedly connected and disconnected for privacy protection, then privacy can be maintained, but human-computer interaction experience deteriorates
Solution Approach 1:
The patent introduces a virtual display interface as an intermediary between the HDMI output and the actual display device. Instead of directly unplugging the HDMI cable for privacy protection, the system routes video output through the virtual display intermediary, which can be dynamically enabled or disabled. This intermediary layer allows privacy protection to be achieved through software switching rather than physical disconnection, significantly improving user experience while maintaining privacy effectiveness.

AI summary
Provided is a multifunctional docking station, including: a PCBA board; a first control module, an image input interface and an image output interface which are arranged on the PCBA board; and a function control module, electrically connected to the first control module and sending an acquired operation instruction to the first control module. In a case that the function control module receives an always-on/screen projection instruction and sends the operation instruction to the first control module, the first control module controls image output of the image output interface through a preset program corresponding to the operation instruction so as to control screen projection content.
