Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack the ability to efficiently manage and display execution screens for multiple applications simultaneously, limiting user convenience and multitasking capabilities.
Innovation Solution
A mobile terminal with a touch screen and controller that outputs slot indicators for first and second execution areas, allowing users to select and display execution screens of recently executed applications, enabling dual window operation and convenient switching between applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile terminal displays execution screens for multiple applications simultaneously, then user convenience and multitasking capabilities are improved, but the device complexity and interface management become more complex
Solution Approach 1:
The display screen is segmented into multiple execution areas (first execution area and second execution area), each capable of independently displaying different application execution screens. Slot indicators are used to mark these segmented areas, allowing users to easily identify and manage each application's display region without confusion.
Solution Approach 2:
The patent transitions from single-application sequential display to multi-application simultaneous display by utilizing spatial dimensionality on the touchscreen. Multiple execution areas are arranged in different positions on the screen, enabling users to access and switch between applications by selecting different spatial regions rather than navigating through application lists.
2Productivity
If a mobile terminal enables dual window operation, then productivity and multitasking are improved, but the ease of switching between applications decreases
Solution Approach 1:
Slot indicators are displayed to provide visual feedback about the current execution areas and their positions on the screen. When users perform gestures or selections within these marked areas, the system provides responsive feedback by switching between the corresponding applications, making the switching mechanism intuitive and easy to understand.
Solution Approach 2:
The system automatically manages the execution areas and application assignments without requiring manual configuration. When a user selects an application, the system automatically assigns it to an appropriate execution area and updates the slot indicators accordingly, eliminating the need for users to manually manage window positions or application mappings.
