Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in managing and limiting their device usage time effectively, particularly for specific applications, categories, and device-level functions, while ensuring privacy and control over multiple devices, especially for children.
Innovation Solution
A system that implements time-based restrictions across multiple devices, using end-to-end encryption to maintain privacy, synchronizes usage data device-to-device, and provides notifications and blocking features to enforce usage limits, allowing users to set quotas and curfews for applications, websites, and device functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If usage data is synchronized across multiple devices, then device usage management effectiveness is improved, but data privacy and security risks increase
Solution Approach 1:
The patent introduces an intermediary server system that facilitates usage data synchronization across multiple devices while maintaining privacy through encrypted communications. The server acts as a mediator that enables cross-device usage tracking without requiring direct data exposure between devices, thus resolving the contradiction between management effectiveness and privacy security.
Solution Approach 2:
The patent replaces direct mechanical data sharing between devices with a communication-based system using network protocols and encryption mechanisms. This substitution allows usage data to be synchronized across devices through secure channels, achieving effective management while minimizing privacy risks through cryptographic protection rather than direct data exposure.
2Productivity
If time-based restrictions are enforced across multiple devices, then responsible usage habits are promoted, but system complexity increases
Solution Approach 1:
The patent implements a universal usage management system that operates across multiple device types (smartphones, tablets, computers) through a common framework. The same core functionality for enforcing time-based restrictions is deployed universally, reducing overall system complexity by avoiding device-specific implementations while still promoting responsible usage habits across diverse platforms.
Solution Approach 2:
The patent uses copying of usage management functionality across multiple devices rather than creating entirely separate systems for each device. The core restriction enforcement mechanism is replicated and adapted for different devices, allowing consistent responsible usage promotion while reducing complexity through functional duplication rather than reinvention.
3Object-affected harmful factors
If usage data is encrypted to maintain privacy, then user privacy is protected, but data accessibility and synchronization difficulty increase
Solution Approach 1:
The patent introduces an intermediary server that handles encrypted data synchronization, shielding clients from encryption complexity. The server acts as a mediator that receives encrypted usage data, processes it according to privacy-preserving protocols, and synchronizes it across devices without requiring the devices themselves to manage complex encryption operations, thus protecting privacy while simplifying accessibility.
Solution Approach 2:
The patent changes the parameter of data storage from plain text to encrypted form, transforming how usage data is handled. This parameter change protects user privacy by ensuring data remains unreadable without proper keys, while the system manages the complexity of encryption and decryption operations through standardized protocols that simplify synchronization between devices.
4Object-affected harmful factors
If device usage time is limited, then excessive usage is prevented, but user convenience and flexibility decrease
Solution Approach 1:
The patent implements dynamic usage time limits that can be adjusted based on various conditions such as device type, user profile, time of day, and usage patterns. Rather than static rigid restrictions, the system dynamically adapts time-based limits to balance excessive usage prevention with user convenience, allowing flexibility while maintaining harm reduction.
Solution Approach 2:
The patent changes the parameter of time limits from fixed values to variable parameters that can be modified based on user needs and usage contexts. This allows the system to prevent excessive usage by default while providing ease of operation through user-friendly parameter adjustment mechanisms, resolving the contradiction between harm prevention and user convenience.

AI summary
A device receives a time-based restriction for usage by a first user with respect to an application, a website or a device-level function. The device receives encrypted data indicating a usage by the first user on a second device with respect to the application, website or device-level function. The device determines that at least one of the usage by the first user on the second device or a usage by the first user on the device with respect to the application, website or device-level function violates the time-based restriction. The device provides, in response to the determining, a notification that the time-based restriction has been violated by the first user.
