Portable USB Key for Computer Parental Control Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parental control systems are cumbersome for parents to configure and use, often requiring technical expertise and proprietary hardware, which deters many from effectively supervising their children's internet activity.
Innovation Solution
A portable hardware device, such as a USB memory stick, is used to provide parental locking functionality by detecting its presence or absence to unlock or lock a computer system, allowing parents to control internet access and other computing capabilities with a simple 'key' mechanism, eliminating the need for complex configuration and proprietary hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parental control software is implemented, then content filtering and blocking capability is improved, but ease of operation deteriorates due to complex configuration requirements
Solution Approach 1:
The patent extracts the configuration complexity from the parental control system by using a portable hardware device that contains pre-configured control settings. Parents simply need to connect the hardware device to the computer, eliminating the need for complex software configuration while maintaining content filtering capability.
Solution Approach 2:
The portable hardware device performs self-configuration and automatically establishes parental control when connected to the computer. The device contains embedded control logic and settings that are automatically applied without requiring parent intervention for configuration, thus improving ease of operation while maintaining filtering reliability.
2Reliability
If proprietary hardware encryption dongle is used, then parental locking functionality is improved, but device complexity and cost worsen
Solution Approach 1:
The patent uses a universal portable hardware device (such as a USB flash drive) that can serve multiple purposes: storing parental control settings, providing authentication, and enabling locking functionality. This replaces the need for proprietary encryption dongles with a common, inexpensive hardware platform that maintains parental locking reliability while reducing device complexity.
Solution Approach 2:
The patent employs inexpensive, readily available portable hardware devices instead of expensive proprietary encryption dongles. The use of common USB flash drives or similar devices reduces hardware costs and complexity while maintaining the essential parental locking functionality through software-based authentication and control mechanisms.

AI summary
A portable hardware device such as a USB memory stick is used to provide parental locking functionality to a computer. When the device is coupled to the computer, the computer is unlocked and allowed to operate normally. When the device is not coupled to the computer, the computer is locked, and some or all of the computing functionality is blocked. This enables parents to lock and unlock a child's computer with a “key.” A detecting module detects the coupling and uncoupling of devices to the computer. When a device is coupled to the computer, an identifying module identifies the device by reading its unique identifier, and determining whether the coupled device is the one being used as the key. If so, the computer is unlocked, and allowed to operate. If not, a blocking module blocks at least some capabilities of the computer.
