Locking USB-C and HDMI Ports to Prevent Sparking Disconnects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current USB and HDMI connectors lack securing mechanisms, leading to potential sparking and health hazards due to unexpected disconnects, while Ethernet cables have locking tabs but no similar security in USB and HDMI connections.
Innovation Solution
The development of data connector configurations that include movable members and blocking mechanisms within ports to mechanically secure cables, detect insertion and removal, and control data and power paths, with embodiments for USB Type-C and HDMI standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If USB Type-C connectors support high power transfer (48V, 5A, 240W), then power delivery capability is improved, but the risk of sparking and damage from unexpected disconnects increases
Solution Approach 1:
The patent implements a locking mechanism that secures the connector before high power transfer begins. The movable member engages with the opening in the connector housing to prevent disconnection during power delivery, eliminating the harmful effect of unexpected disconnects while maintaining full power capability.
2Adaptability or versatility
If USB and HDMI connectors lack securing mechanisms, then device compatibility and ease of connection are improved, but connection stability and safety deteriorate
Solution Approach 1:
The locking mechanism features a movable member that transitions between engaged and disengaged states. During normal operation, the movable member engages to secure the connector. When removal is needed, the movable member can be actuated to release the lock, maintaining user control while ensuring connection stability during use.
3Reliability
If Ethernet cables include locking tabs, then connection security is improved, but USB and HDMI connections remain insecure without similar mechanisms
Solution Approach 1:
The locking mechanism is designed to work with various connector types including USB Type-C and HDMI connectors. The movable member and opening configuration can be adapted to different connector geometries, providing Ethernet-like security across multiple connector standards without requiring separate solutions for each type.
4Reliability
If a locking mechanism is added to USB Type-C connectors, then connection security is improved, but device complexity increases
Solution Approach 1:
The movable member is integrated within the port housing structure, nesting the locking mechanism within the existing connector geometry. This approach minimizes additional components and structural complexity while providing effective locking functionality. The movable member utilizes space within the existing port configuration rather than adding external complexity.

AI summary
Aspects of the subject disclosure may include, for example, a device comprising: a female port configured to receive a data connector, the data connector comprising a surface with a first opening; a first movable member disposed within the female port, the first movable member being configured such that as the data connector is moved into the female port a first portion of the first movable member enters into the first opening; and a first blocking member disposed within the female port, the first blocking member being configured to move to a first blocking position to block the first portion of the first movable member from exiting the first opening after the first portion of the first movable member has entered the first opening. Other embodiments are disclosed.
