Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
USB ports are vulnerable to data extraction and malicious software infiltration, and existing security solutions do not effectively secure USB connectors or flash drives within these ports.
Innovation Solution
A port connector securement device comprising a resting piece with a user-definable rectangular surface and a planar surface with projections, which fits within the USB port to prevent removal without evidence of tampering, using materials like plastic, glass, or polymers, and a wire loop seal to secure the USB cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a USB port is left open for connectivity, then ease of operation is improved, but security against data extraction and malicious software infiltration deteriorates
Solution Approach 1:
The security device is pre-installed in the USB port before any connector is inserted. When a connector is connected, the device automatically positions itself to block access to the port's internal components, preventing tampering before it can occur. This preliminary positioning action resolves the contradiction by maintaining open connectivity while pre-establishing security barriers.
2Object-affected harmful factors
If a security device is added to secure the USB port, then security is improved, but device complexity increases
Solution Approach 1:
The security device is divided into distinct functional segments: a blocking component that prevents access to port internals, a securing mechanism with projections that engage with the connector, and a tamper-evident indicator system. This segmentation allows each component to perform its specific function independently, achieving comprehensive security without requiring a monolithic complex structure.
Solution Approach 2:
The security device is designed to nest within the USB port housing, with the blocking component fitting inside the port cavity and the securing mechanism integrating with the port's existing structure. This nesting approach minimizes the overall device footprint and reduces complexity by utilizing the port's existing geometric constraints rather than adding external bulky components.
3Object-affected harmful factors
If a blocking device is inserted into the USB port, then port security is improved, but ease of operation deteriorates
Solution Approach 1:
The blocking component is designed with dynamic positioning capability, allowing it to move between a blocked position (when no connector is present) and an engaged position (when a connector is inserted). The securing mechanism includes movable projections that automatically engage with the connector's corresponding features during insertion, eliminating the need for manual intervention and maintaining ease of operation while providing security.
Solution Approach 2:
The security device incorporates self-activating features where the act of inserting a connector automatically triggers the blocking component to secure the port and the tamper-evident indicator to activate. The device serves itself by using the connector's insertion motion to engage the security mechanism, eliminating the need for separate user actions to activate security features and maintaining operational simplicity.
4Difficulty of detecting and measuring
If a tamper-evident mechanism is added to the security device, then detection capability is improved, but device complexity increases
Solution Approach 1:
The tamper-evident indicator utilizes color-changing materials or visible markers that change state when tampering occurs. For example, a color-changing polymer or a visible break line that reveals a contrasting color when the connector is forcibly removed. This approach provides clear tamper detection through simple visual observation without requiring complex electronic sensors or detection systems, thus improving detection capability while minimizing added complexity.

AI summary
The present invention is a port connector securement device comprising a resting piece, a planar surface, and at least one projection extending from the bottom of the planar surface where the at least one projection rests within at least one slot of an USB port when the port connector securement device is slideably insertable, along with the USB cable into the USB port to ensure that the USB cable cannot be removed upon the port connector securement device insertion into the USB port.
