Portable Terminal Display Mode Switching via Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable terminal apparatuses with multiple display units lack easy switching between display modes, such as separate screen and full screen displays, which hampers user convenience.
Innovation Solution
A portable terminal apparatus with a support mechanism allowing switchable display unit arrangements, a state detection unit to identify these arrangements, and a control unit to adjust the display mode accordingly, enabling seamless transitions between open, tilt, and closed states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display units are arranged adjacently to enable separate screen display, then display functionality and user convenience are improved, but device complexity increases due to the need for switchable support mechanisms
Solution Approach 1:
The support mechanism is designed to be dynamically switchable between multiple states (open, tilt, closed) to accommodate different display modes. The mechanism includes movable components that can transition between positions, allowing the display units to be arranged adjacently for separate screen display or in other configurations for full screen display, thereby providing adaptability without permanent structural complexity
Solution Approach 2:
The support mechanism serves multiple functions by enabling various display arrangements (adjacent arrangement for separate screen display, other arrangements for full screen display) through a single integrated structure. This multi-functional design allows the device to adapt to different usage scenarios without requiring separate mechanisms for each display mode
2Ease of operation
If display mode switching requires additional input mechanisms, then control precision is improved, but ease of operation deteriorates due to increased number of controls
Solution Approach 1:
The system automatically detects the physical arrangement state of the display units through sensors (such as angle sensors or position sensors) and autonomously determines the appropriate display mode without requiring user input. The control unit processes the detected arrangement information and automatically switches between separate screen display and full screen display modes, eliminating the need for additional control mechanisms
Solution Approach 2:
The system incorporates feedback loops where sensors continuously monitor the physical state of the display units and provide this information to the control unit. Based on this feedback, the control unit dynamically adjusts the display mode, creating a closed-loop control system that responds to physical arrangement changes automatically without requiring user intervention
