Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile terminal uses traditional external display connection methods (clone mode or video only mode), then the connection is simple to implement, but the screen utilization efficiency is low and functionality is limited
Solution Approach 1:
The patent implements dynamic display mode switching between clone mode, video only mode, and desktop mode based on user selection. The system can dynamically adjust the display configuration by receiving a selection signal from the user and switching between different display modes, thereby providing adaptability while maintaining manageable complexity through a unified connection framework
Solution Approach 2:
The mobile terminal is designed to support multiple display modes (clone mode, video only mode, desktop mode) through a single external display connection interface. This multi-functional capability allows the same hardware connection to serve different purposes, improving adaptability without requiring separate dedicated hardware for each mode
2Ease of operation
If the mobile terminal uses a touchscreen interface for control, then the user interface is intuitive and compact, but it cannot effectively control external display devices with different screen sizes and layouts
Solution Approach 1:
The patent introduces a virtual input device as an intermediary between the touchscreen interface and the external display device. This virtual input device receives touch inputs from the user and translates them into appropriate control signals for the external display, enabling the compact touchscreen to effectively control larger external displays with different layouts and sizes
Solution Approach 2:
The system replaces direct physical control mechanisms with a software-based virtual input device that mediates between the touchscreen and external display. This substitution allows the intuitive touchscreen interface to work with various external display configurations without requiring physical adjustments or additional hardware controls
3Productivity
If the mobile terminal displays the same layout on external display devices of different sizes, then the implementation is simple, but the screen utilization efficiency is low
Solution Approach 1:
The patent implements dynamic layout adjustment based on the external display device's characteristics. The system receives information about the external display device and automatically adjusts the display layout to optimize screen utilization, switching between different layout configurations depending on the display size and type
Solution Approach 2:
The system applies different display layouts tailored to specific external display device characteristics. Instead of using a uniform layout for all external displays, the patent creates localized display configurations optimized for different display sizes and types, thereby improving screen utilization efficiency for each specific display scenario
4Ease of operation
If additional external input devices are required for controlling the external display, then the control capability is enhanced, but the device cost and complexity increase
Solution Approach 1:
The mobile terminal uses its own touchscreen interface to control the external display device through the virtual input device. This self-service capability eliminates the need for separate external input devices, as the mobile terminal's built-in touchscreen is sufficient to provide full control functionality for the external display
Solution Approach 2:
The mobile terminal's touchscreen interface is designed to serve dual purposes: displaying content and controlling the external display. By making the touchscreen multi-functional, the system eliminates the need for additional dedicated input devices, reducing overall system complexity while maintaining enhanced control capability
