Display Device External Device Use Restriction Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to restrict the use of external devices connected to display devices, particularly to prevent indiscreet use by adolescent boys or children, as existing technologies lack a user-friendly method to control access and usage time.
Innovation Solution
A display device with a media interface unit to detect external devices, a memory unit to store unique information, and a control unit to register and permit or restrict use based on the unique information, allowing for time-based restrictions and registration of external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no user restriction is set, then external devices can be used freely by anyone, but adolescent boys or children can misuse external devices without restriction
Solution Approach 1:
The system performs preliminary actions by detecting external devices and automatically registering them before misuse can occur. The control unit proactively manages device registration and restriction settings, preventing child misuse before it happens rather than reacting to it later.
Solution Approach 2:
The system provides self-service functionality where the control unit automatically detects, registers, and manages external devices without requiring manual user intervention. The device autonomously maintains the restriction database and applies restrictions, reducing the burden on users while preventing misuse.
2Object-affected harmful factors
If a use restriction function is implemented to prevent misuse, then child misuse is restricted, but the system complexity increases
Solution Approach 1:
The patent merges the restriction management functionality into the existing display device control unit, combining device detection, registration, and restriction application in a single integrated system. This avoids adding separate complex restriction hardware or software layers.
Solution Approach 2:
The control unit performs multiple functions: it detects external devices, registers them in the database, manages restriction settings, and applies restrictions based on time and device type. This multi-functional approach eliminates the need for separate dedicated restriction management components.
3Reliability
If manual device registration is required for each external device, then precise control is achieved, but the operation process becomes complicated
Solution Approach 1:
The system performs preliminary automatic detection and registration of external devices before the user needs to use them. By the time the user wants to restrict or use a device, it is already registered in the database, eliminating the need for manual registration steps.
Solution Approach 2:
The control unit automatically detects external devices and registers them in the restriction database without user intervention. The system serves itself by maintaining an up-to-date registry of connected devices, freeing users from manual registration tasks while ensuring precise control is maintained.

AI summary
Provided are a display apparatus and a use restriction method thereof. The display apparatus includes a media interface unit, a memory unit, and a control unit. The media interface unit detects the connection of an external device and receives unique information of the connected external device. The memory unit stores the unique information of the external device received through the media interface unit. The control unit stores/registers the unique information of the connected external device in the memory unit and determines whether to permit the use of the external device connected through the media interface unit on the basis of the unique information registered in the memory unit. Herein, upon detecting the connection of an unregistered external device, the control unit restricts the use of the unregistered external device on the basis of the registered unique information of the external device.
