Tamper-Evident Port Protector With Segmented Tongue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data ports on computers and vehicles are vulnerable to unauthorized access, lacking effective mechanisms to prevent or evidence such access.
Innovation Solution
A tamper-evident port protector with a base member and slide member that locks onto the port, requiring removal of a tongue to disengage and provide evidence of access, utilizing frangible members to ensure irreversible removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a port protector is designed to be easily removable for convenience, then ease of operation is improved, but security and tamper evidence are worsened
Solution Approach 1:
The base member is segmented into a removable tongue portion and a remaining body. The tongue can be cleanly removed from the base, allowing the port protector to be taken off while leaving visible evidence of removal. This segmentation enables the dual function of easy removal for operational convenience while maintaining security through tamper evidence.
2Device complexity
If a port protector uses a simple locking mechanism, then device complexity is reduced, but reliability of preventing unauthorized access deteriorates
Solution Approach 1:
The port protector is pre-installed and locked into place before any unauthorized access attempt occurs. The locking mechanism is engaged in advance, requiring deliberate action (removal of the tongue) to disengage. This preliminary locking action provides reliable protection without requiring complex active monitoring or control systems.

AI summary
A port protector is provided by a base member that engages the port and a slidably mounted slide member. Locking members are provided on the base member and the slide member such that when the locking members are engage the slide member does not slide relative to the base member. Unlocking of the port protector is achieved by removing or perforating a tongue of the base. Removal of the tongue provides evidence that access to the port was achieved.
