USB Connector Locking Arrangement with Pin and Receptor Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing USB connectors are prone to unauthorized or inadvertent disconnection, leading to data loss due to their ease of disconnection, which is insufficient for securing connections against physical accidents or unauthorized access.
Innovation Solution
A locking arrangement for USB connectors featuring receptor and pin portions that securely engage to prevent disconnection, with a secured actuation device for locking and unlocking, applicable to both single and stacked connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If USB connectors use simple detents for connection, then ease of operation is improved, but connection security deteriorates
Solution Approach 1:
The locking arrangement is segmented into distinct functional components: a locking mechanism with movable locking elements (pins or clips), an actuation mechanism for controlled operation, and engagement features with specific geometries. This segmentation allows each component to be optimized independently while working together to provide both secure locking and easy operation through the actuation feature.
Solution Approach 2:
The locking elements are designed to be movable rather than fixed, transitioning between locked and unlocked positions. The actuation mechanism enables dynamic control of the locking state, allowing the connector to switch between secure engagement and easy disconnection based on user action, thus resolving the contradiction between security and ease of operation.
2Ease of operation
If USB connectors are designed for easy disconnection, then ease of operation is improved, but data security deteriorates
Solution Approach 1:
The locking mechanism applies a preliminary counter-force to prevent unauthorized or accidental disconnection. The locking elements engage with the connector housing to create mechanical resistance against separation forces, thereby preventing inadvertent disconnections that could lead to data loss while still allowing authorized disconnection through the actuation mechanism.
3Reliability
If USB connectors use locking mechanisms, then connection security is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is merged with the connector housing and internal structures, utilizing existing connector components as integral parts of the locking system. The locking elements, actuation features, and engagement surfaces are integrated into the overall connector design rather than being separate add-on components, thereby reducing overall device complexity while maintaining connection security.
Solution Approach 2:
The locking mechanism is designed to be self-actuating through spring-loaded elements or cam mechanisms that automatically engage when connectors are mated. The actuation mechanism utilizes the connector's own structural features and applied forces to operate the locking elements, eliminating the need for external actuators or complex control systems.

AI summary
A USB connection arrangement, where more secure locking is afforded than has hitherto been achieved. With a first USB connecting portion and a second USB connecting portion, a locking arrangement is provided for physically securing the first USB connecting portion and the second USB connecting portion with respect to one another. The locking arrangement includes at least one receptor portion disposed on at least one of the first and second USB connecting portions, and at least one pin portion engageable with the at least one receptor portion for physically securing at least one of the first and second connecting portions with respect to the other of the first and second connecting portions.
