User Terminal Operability Control for Usage Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively suppress long-time use of user terminals without obstructing user work, as either warning messages are ignored or forced termination disrupts essential activities.
Innovation Solution
A user terminal with a usage amount acquisition unit and control unit that reduces operability when usage exceeds a threshold, prompting users to stop without forced termination, by decreasing scroll speed and response times gradually as usage exceeds the limit.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a warning message is displayed before the usage time limit is reached, then the user is prompted to stop use of the application, but the user can continue to use the application without regard to the warning message, resulting in an insufficient effect of suppressing the long-time use of the user terminal
Solution Approach 1:
The system dynamically changes the operability of the user terminal based on the accumulated usage time. When the usage time exceeds a predetermined threshold, the system automatically reduces operability by making operations such as scrolling, typing, and navigation more difficult, creating a dynamic feedback mechanism that adapts to the user's usage behavior
Solution Approach 2:
The system changes the parameter of operability from normal to reduced state when the usage time parameter exceeds the threshold. This involves modifying system parameters such as response delays, input sensitivity, and operation smoothness to create a tangible deterrent against excessive usage
2Object-affected harmful factors
If the use is limited strictly such that the application is forcibly terminated if the usage time of the application reaches the usage time limit, then the long-time use is suppressed, but the application is forcibly terminated even when the user is under special situation that the user has to use the application beyond the usage time limit, resulting in greatly obstructing the user's work
Solution Approach 1:
The system provides dynamic control over usage limitation, allowing the operability to be reduced rather than completely blocked. This dynamic approach enables users to continue using the terminal during special situations while still experiencing the deterrent effect of reduced operability
Solution Approach 2:
Instead of completely blocking usage when the threshold is exceeded, the system applies partial limitation by reducing operability. This partial action allows users to continue working when necessary while still receiving the intended deterrent effect for normal excessive usage scenarios
3Object-affected harmful factors
If the operability of the user terminal is reduced when the amount of usage exceeds the threshold value, then the user can be prompted to stop using the user terminal, but the use of the user terminal itself is not forcibly prohibited, requiring a balance between suppression effectiveness and user autonomy
Solution Approach 1:
The system dynamically adjusts operability based on real-time usage monitoring, creating a flexible control mechanism that can adapt to different usage scenarios without requiring rigid predetermined rules
Solution Approach 2:
The system provides continuous feedback to the user about their usage status and the corresponding operability changes, allowing users to understand the relationship between their usage behavior and the system's response, thereby enabling more informed decision-making about their usage patterns
