USB Hub Privacy Switch for Selective Data Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current USB technologies lack a straightforward method for users to selectively enable or disable data communication while maintaining power transfer, which is essential for privacy and efficiency in device connections.
Innovation Solution
Incorporating a switch mechanism into USB cables and multiport hubs that allows users to toggle between modes to enable or disable data communication while keeping power transfer operational, using privacy switches that can be manually actuated to set specific modes for individual ports or the entire hub.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If USB interface enables data communication between devices, then connectivity and data transfer functionality is improved, but user privacy and data security may be compromised
Solution Approach 1:
The patent implements a dynamic switching mechanism that allows the USB interface to transition between different operational modes (data communication enabled/disabled, power transfer only). This dynamic capability resolves the contradiction by enabling users to adapt the interface state to their privacy needs while maintaining full functionality when required.
Solution Approach 2:
The patent segments the USB interface functionality into separate controllable modes: data communication mode and power transfer mode. By dividing the unified USB interface into distinct functional segments that can be independently activated or deactivated, users can enable data communication when needed while preventing it when privacy is a concern.
2Adaptability or versatility
If USB interface provides both data communication and power transfer, then functionality is improved, but complexity of control increases
Solution Approach 1:
The patent implements self-service through automatic mode detection and switching. The system automatically determines whether to enable data communication or power transfer based on the connected device type and user preferences, eliminating the need for manual configuration and simplifying user interaction while maintaining full functionality.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the USB interface with default modes and switching capabilities before device connection. The system is prepared with multiple operational states and can automatically transition between them, reducing the complexity of real-time control decisions.
3Ease of operation
If USB interface allows hot-swapping of devices, then ease of use is improved, but risk of unauthorized data access increases
Solution Approach 1:
The patent implements feedback mechanisms that monitor device connection events and automatically adjust interface permissions accordingly. When a device is hot-swapped, the system detects the connection, identifies the device type, and automatically enables or disables data communication based on predefined security policies, maintaining ease of use while preventing unauthorized access.

AI summary
A connection hub includes a housing coupled to a universal serial bus (USB) cable that includes a plug for electronic devices. A housing of the connection hub includes a number (N) of ports and switches. The connection hub includes 1-to-N connections between the USB cable and the N ports, where each of the N ports includes a data line and/or a power line. The switches each include a mechanical component that is movable between a first position that activates a private mode and a second position that deactivates the private mode. A data line of a particular port is disabled when the private mode is activated, and a particular power line of the particular port is enabled when either the private mode is activated and when the private mode is deactivated.
