Mobile Terminal Multi-Application Control Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face difficulties in simultaneously activating and controlling multiple applications due to their characteristics, which hinders the ability to share control rights with external terminals effectively, leading to confusion in control commands.
Innovation Solution
A mobile terminal equipped with a wireless communication unit, display unit, and controller that allows for the execution of multiple applications, enabling the transmission and reception of wireless signals to control external applications, with the controller managing the display to add or change content and position of control screens based on user input and wireless signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single application is executed to allow control right sharing with external terminals, then control command confusion is prevented, but the ability to simultaneously activate and control multiple applications is limited
Solution Approach 1:
The patent divides the control interface into separate control screens for each application. When multiple applications are executed, each application has its own dedicated control screen that can be selectively displayed or overlaid, allowing external terminals to control specific applications without interfering with others. This segmentation resolves the contradiction by enabling multi-application control while maintaining clear, application-specific control commands.
Solution Approach 2:
The patent introduces a spatial dimension by overlaying control screens in different positions on the display. Instead of switching between single-application modes, the system displays multiple control screens simultaneously in different locations, allowing users to access and control multiple applications without command confusion. Each control screen is positioned to correspond to its associated application, creating a multi-dimensional control interface.
2Adaptability or versatility
If control screens for multiple applications are displayed simultaneously, then multi-application control is enabled, but control command confusion occurs
Solution Approach 1:
The patent applies local quality by making each control screen have distinct visual characteristics and positioning. Each control screen is designed with unique properties (such as position, size, or visual style) that correspond to its associated application. This allows the system to display multiple control screens simultaneously while maintaining clear differentiation, preventing command confusion through localized visual identification.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a controller that manages the display and positioning of multiple control screens. The controller receives control commands from external terminals, identifies the target application, and directs commands to the appropriate control screen. This intermediary layer ensures that even when multiple control screens are displayed, commands are accurately routed to the intended application, preventing confusion.
3Adaptability or versatility
If content on execution screen is added or changed based on user input, then application functionality is enhanced, but control screen position must be adjusted
Solution Approach 1:
The patent implements dynamics by making control screen positions adjustable and responsive to content changes. When content is added or changed on the execution screen, the control screen automatically repositions itself to maintain optimal layout and accessibility. This dynamic positioning system allows the interface to adapt to varying content requirements without manual intervention, managing complexity through automated responsive behavior.
