Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing child mode technologies prevent kids from accessing inappropriate content but hinder normal usage of applications, failing to allow controlled access to necessary functions.

Innovation Solution

A method and device that allow the reception of allowed or prohibited function lists from a parent terminal, enabling selective display and execution of functions, content filtering, and communication management to ensure normal application usage while restricting inappropriate content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If child mode disables startup of corresponding applications to prevent kids from contacting inappropriate content, then safety control is improved, but normal usage of applications is hindered

Engineering Contradiction:

Improveinappropriate content accessVSAvoidapplication usage

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent segments application functions into two categories: child-accessible functions and adult-only functions. The child mode selectively disables only the adult-only functions while keeping child-accessible functions operational, allowing children to use appropriate features without complete application lockdown.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies different access control qualities to different functions within the same application. Each function is tagged with access level attributes, enabling the system to apply restrictive control only where necessary (adult-only functions) while maintaining normal access for safe functions.

Inventive Principle:

Principle #3Local quality

2Reliability

If child mode completely disables applications to ensure safety, then content protection is improved, but application functionality is lost

Engineering Contradiction:

Improvesafety controlVSAvoidapplication functionality

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic function filtering where the system adapts its control behavior based on the child mode state and function attributes. The filtering mechanism dynamically evaluates each function request against the child mode configuration, enabling or disabling functions in real-time based on their safety classification.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces a function filtering mechanism as an intermediary layer between the application and the child mode control system. This intermediary selectively permits or blocks function execution based on pre-defined safety criteria, maintaining both safety control and functional versatility.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The disclosure relates to a method and a device for processing a child mode, belonging to the field of internet technology. The method includes: a terminal device receiving an allowed function list and a prohibited function list of a target application sent from a first terminal (101); determining allowed functions in the target application according to the allowed function list or the prohibited function list (102); and displaying the allowed functions under a child mode of the target application (103). By the disclosure, normal usage of applications is not affected under the child mode.
