USB-C Slot Lock Assembly for Mobile Device Theft Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security solutions for electronic mobile devices (EMDs) at USB-C ports are inadequate in preventing theft, as they do not effectively utilize the USB-C openings to provide secure locking mechanisms that can be easily integrated with the devices.
Innovation Solution
A lock assembly with arcuately-shaped locking elements that fit within the USB-C slot, featuring a user-controlled locking mechanism, a cable assembly for affixing to an immovable object, and complementary shapes to securely engage with the USB-C slot, preventing separation from the EMD.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing security solutions are used for USB-C ports, then the device maintains its original design, but the security against theft is insufficient
Solution Approach 1:
The locking elements are nested within the USB-C slot structure itself. The first locking element is received within the slot with flared walls, and the second locking element is received within the first locking element, creating a nested configuration that provides security without adding external protrusions or complex external mechanisms to the device
Solution Approach 2:
The USB-C slot structure serves dual functions: its original electrical connection function and a new security locking function. The flared walls of the slot are designed to receive and secure the locking elements, transforming the existing USB-C opening into a multi-functional component that provides both data/power connection and theft prevention
2Reliability
If locking elements are made to tightly engage the slot walls, then security is improved, but manufacturing precision requirements increase
Solution Approach 1:
The slot incorporates flared walls that curve outward, and the locking elements have corresponding curved engagement surfaces. This curvature allows the locking elements to wedge securely against the flared walls through a self-centering mechanism, providing tight engagement while being more tolerant of manufacturing variations compared to flat, precision-matched surfaces
3Length of moving object
If the device wall thickness is kept under 2.5 mm, then device portability is improved, but the slot structure must be highly integrated
Solution Approach 1:
The security slot structure is merged with the existing USB-C port opening. The flared walls of the slot utilize the same wall space as the USB-C opening, and the locking elements are received within the same structural envelope, eliminating the need for separate security port openings and reducing overall device thickness requirements

AI summary
A lock assembly for preventing theft of an electronic mobile device (EMD) is configured to engage a slot formed in the 2 mm thick outer wall of the EMD. The slot has top and bottom outwardly-flaring side walls extending away from the opening. The lock body supports first and second locking elements, each of which is configured to be insertable into the slot and has a top wall and a bottom wall that are complementary in shape to the top wall and the bottom wall the of the slot. The first and second locking elements cooperate structurally to become wedged inside the slot in manner that prevents separation of the lock body from the EMD while the first and second locking elements are positioned inside the slot.
