Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart electronic devices have become addictive, leading to distractions and societal issues, and there is a need for systems that can manage device usage to mitigate these effects.
Innovation Solution
Blocker devices and temporary unlocking devices that use Near Field Communication (NFC) protocols to change device configurations, allowing or restricting access to applications based on authentication with security tags, and setting temporary configurations that lapse after a threshold time or usage limit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a blocker device is used to prevent interaction with applications, then device usage addiction is reduced, but user accessibility to necessary applications is restricted
Solution Approach 1:
A physical blocker device acts as an intermediary between the user and the electronic device. The blocker device contains an NFC tag that communicates with the electronic device to enforce usage restrictions. This intermediary mechanism allows the system to maintain control over application access while reducing direct user interaction that leads to addiction, thereby resolving the contradiction between reducing harmful usage and maintaining necessary accessibility.
Solution Approach 2:
The system dynamically changes the state of application accessibility based on the presence or absence of the blocker device. When the blocker device is detected via NFC communication, the system transitions to a restricted state where certain applications cannot be accessed. When the blocker device is removed, the system returns to an unrestricted state. This dynamic behavior allows the system to adapt between reducing addiction and maintaining accessibility based on real-time conditions.
2Object-affected harmful factors
If strict usage restrictions are enforced to reduce addiction, then harmful usage patterns are reduced, but user flexibility and control are reduced
Solution Approach 1:
The user performs preliminary configuration by selecting which applications should be restricted and under what conditions before using the blocker device. The system stores these pre-defined rules and automatically enforces them when the blocker device is present. This preliminary action allows the user to maintain flexibility in designing their own usage patterns while the system handles the strict enforcement, resolving the contradiction between reducing addictive patterns and maintaining user control.
Solution Approach 2:
The system provides multiple configurable restriction modes and conditions that can be dynamically adjusted. Users can define different levels of restriction for different applications and time periods. The system adapts its behavior based on the specific configuration chosen, allowing users to maintain flexibility in how restrictions are applied while still enforcing rules that reduce addictive usage patterns.
3Extent of automation
If automatic configuration changes are implemented to manage usage, then user control over addiction is improved, but system complexity increases
Solution Approach 1:
The electronic device automatically detects the presence of the blocker device via NFC communication and self-adjusts its configuration without requiring user intervention. The system automatically enforces the pre-configured restrictions by monitoring for the blocker device and changing application accessibility states accordingly. This self-service automation reduces the need for complex manual management while maintaining effective usage control, resolving the contradiction between automatic management and system complexity.
Solution Approach 2:
The complex logic for enforcing usage restrictions is extracted from the electronic device and placed in the external blocker device. The blocker device contains the NFC tag and the logic for when restrictions should be applied, separating this functionality from the main electronic device. This extraction simplifies the electronic device's complexity while maintaining automatic usage management capabilities through the external blocker device.

AI summary
A blocker device changes a configuration of a user smart device by locking certain applications of the user smart device. A temporary unlocking device provides for the user smart device to be temporarily unlocked after the blocker device has locked the user smart device. The user smart device, when disposed within a certain distance of the temporary unlocking device, receives a signal from the temporary unlocking device and determines that the temporary unlocking device is disposed within a certain distance of the user device and that conditions allow for temporary unlocking of the user device. The user device is then temporarily unlocked for a limited duration.
