USB-C Port Security Apparatus with Reversible Interference Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data processing systems face security vulnerabilities due to physical port access, which can lead to unauthorized access and theft, as existing security measures are not effective in preventing malicious activities through these ports and do not adequately anchor the devices to prevent movement.
Innovation Solution
A security apparatus with a reversible interference mechanism that locks onto universal serial bus type C ports, transitioning between configurations to allow insertion and prevent removal, combined with a security cable for anchoring to nearby structures, thereby limiting physical access and reducing theft susceptibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical port access is allowed, then device connectivity and functionality are improved, but security vulnerabilities and unauthorized access increase
Solution Approach 1:
The port cover is designed to dynamically transition between a retracted state (allowing port access) and a extended state (blocking port access). This dynamic mechanism resolves the contradiction by adapting the port accessibility based on security requirements while maintaining connectivity functionality when needed.
Solution Approach 2:
The port cover acts as an intermediary element between the external environment and the USB-C port. It mediates the access to the port by allowing controlled interaction through its opening while preventing direct unauthorized access, thus resolving the security connectivity contradiction.
2Object-affected harmful factors
If security measures are added to prevent port access, then security is improved, but device mobility and ease of operation deteriorate
Solution Approach 1:
The port cover's dynamic nature allows it to be easily retracted when security is not a concern, maintaining device mobility and ease of operation. The cover only extends to provide security protection when needed, thus resolving the contradiction between security and operational ease.
Solution Approach 2:
The port cover is designed to be self-actuating through the reversible interference mechanism, allowing it to automatically transition between states without requiring complex user intervention. This self-service capability maintains ease of operation while providing effective security protection.
3Object-affected harmful factors
If a locking mechanism is implemented to prevent port access, then security is improved, but device complexity increases
Solution Approach 1:
The port cover is nested within the security apparatus body, with the reversible interference mechanism integrated into the cover structure itself. This nesting approach minimizes overall device complexity while providing effective security protection through the compact, hierarchical design.
Solution Approach 2:
The port cover serves multiple functions: it provides security protection when extended, maintains connectivity access when retracted, and integrates with the reversible interference mechanism for secure locking. This multi-functionality reduces the need for separate components, thereby reducing overall device complexity.

AI summary
Methods and systems for securing data processing systems are disclosed. A data processing system may be operably connected to other devices via ports. When operably connected, some devices connected via the ports may cause undesired actions to be performed. To limit physical access to the ports, a security apparatus may be used to lock the ports. The security apparatus may transition between states where it may be inserted into openings for the ports and may be locked to the openings for the ports. When so locked, physical access to the ports may be limited.
