USB Port Blockout Device Using Front-Engaging Metal Clips

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing USB port lock devices are not compatible with all USB ports as they rely on openings on the top side, failing to provide a secure, tamper-resistant blockout solution for all USB ports.

Innovation Solution

A blockout device with a front cover that engages metal clips within the USB port's channel, featuring stepped ledges to secure the device and prevent removal, and an optional removable design using a removal tool for easy installation and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If prior USB port lock devices engage the openings on the top side of the USB port, then the port is protected from contamination and misuse, but the device is not compatible with all USB ports that lack top side openings

Engineering Contradiction:

Improvecompatibility with different USB port designsVSAvoidsecurity protection effectiveness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Instead of engaging the USB port from the top side as in prior devices, this invention inverts the approach by engaging the metal clips from the front/bottom side. The blockout device is inserted through the front opening and secures to the metal clips that extend into the channel, making it compatible with all USB ports regardless of top side opening presence.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The invention changes the engagement dimension from top-side horizontal engagement to front-side vertical engagement. The blockout device engages the metal clips in the depth dimension of the USB port channel rather than relying on top-side openings, providing universal compatibility while maintaining secure engagement.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If the blockout device is designed to be permanently secured to the USB port, then tamper resistance is improved, but ease of installation and removal deteriorates

Engineering Contradiction:

Improvetamper resistanceVSAvoidease of installation and removal

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The blockout device employs a dynamic engagement mechanism where the sides flex or deform during insertion to engage the metal clips, and can be dynamically disengaged using a removal tool. This allows the device to transition between a securely locked state (tamper resistant) and a removable state (easy operation) as needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

A removal tool is introduced as an intermediary device to facilitate the removal of the blockout device. The removal tool engages with the blockout device and applies force to disengage the sides from the metal clips, allowing easy removal without requiring force or damage to the USB port, while maintaining tamper resistance during normal use.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A blockout device for a USB port is disclosed. The USB port has an inner channel and metal clips positioned within the channel. The blockout device has a front that covers the inner channel of the USB port. The blockout device also includes a top, a bottom and sides extending from the front. The bottom extends parallel to the top with an open area therebetween. When the blockout device is installed in the USB port, the sides engage the metal clips positioned in the channel of the USB port to secure the blockout device to the USB port.
