Docking Station Status Notifications via On-Screen Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing device docking stations lack effective means to communicate their status to users without a connected host computing device, relying on confusing LED indicators that may not accurately convey status information.
Innovation Solution
A computing device docking station with a dock management controller that determines its own status and generates a visual notification, such as a bitmap image, to be displayed on connected display devices, even when not connected to a host computing device, using a display controller to present this information in a user-friendly format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If LED indicators are used to communicate docking station status, then the docking station can provide status information without a host computing device, but the status communication is confusing and may not accurately convey status information
Solution Approach 1:
The patent introduces an intermediary system consisting of a dock management controller and display controller that translates docking station status into visual OSD notifications on connected display devices. This intermediary layer converts raw status data into user-friendly graphical representations, resolving the contradiction between providing status information and ensuring user comprehension.
Solution Approach 2:
The patent replaces the mechanical/optical LED indicator system with an electronic display system using OSD (on-screen display) technology. This substitution enables more complex and accurate status communication by utilizing graphical interfaces, text, and icons that can convey multiple pieces of information simultaneously and unambiguously.
2Loss of information
If the docking station relies on the host computing device to display status information, then the host can process and present the data, but the docking station cannot communicate status when not connected to a host
Solution Approach 1:
The patent implements self-service by enabling the docking station to independently generate and communicate its own status information through integrated controllers and display capabilities. The dock management controller and display controller work together to autonomously present status notifications on connected display devices without requiring host computing device involvement, allowing the docking station to function and communicate status even when disconnected from a host.
3Loss of information
If detailed status information is provided to users, then users are fully informed of docking station conditions, but the communication system becomes more complex
Solution Approach 1:
The patent applies multi-functionality by using a single display controller to handle multiple status notification tasks simultaneously. The controller can present various types of status information (overcurrent events, overvoltage events, connection status, etc.) through a unified OSD interface, eliminating the need for separate communication systems for each type of status information and managing complexity through consolidation.

AI summary
In an example in accordance with the present disclosure, a computing device docking station is described. The computing device docking station includes a computing device port to receive a connector of a host computing device and a display device port to receive a connector of a display device. The computing device docking station also includes a dock management controller. The dock management controller is to 1) determine a status of the computing device docking station and 2) generate a notification indicating the status of the computing device docking station. The computing device docking station also includes a display controller to generate an on-screen display (OSD) presentation of the notification on the display device coupled to the display device port.
