Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate keypad is installed in a mobile terminal with foldable display, then the user interface for various functions is improved, but the device size and portability are compromised
Solution Approach 1:
The patent merges the keypad functionality with the display unit by implementing a virtual keypad on the touch screen. This integration eliminates the need for a separate physical keypad while maintaining the input functionality, thereby improving ease of operation without increasing device volume.
Solution Approach 2:
The display unit serves multiple functions: it acts as both the display screen and the input interface through the virtual keypad. This multi-functionality allows the device to maintain comprehensive operational capabilities while minimizing the overall device size by eliminating dedicated input hardware.
2Volume of moving object
If the display unit is folded at a particular angle, then portability is improved, but image discontinuity and blurring occur near the foldable zone
Solution Approach 1:
The patent implements dynamic image adjustment based on the folding angle detected by the angle sensor. The control unit dynamically modifies the display output to compensate for geometric distortion and image discontinuity that occur at different folding angles, thereby maintaining image quality while enabling portable folded configurations.
Solution Approach 2:
The angle sensor provides real-time feedback about the folding angle to the control unit, which then adjusts the display parameters accordingly. This feedback mechanism enables the system to automatically compensate for image distortion caused by folding, maintaining image continuity across the foldable zone.
3Adaptability or versatility
If multiple linked display zones are used, then functionality and user interface are improved, but device complexity increases
Solution Approach 1:
The display unit is segmented into multiple independently controllable display zones that can be selectively activated based on the folding angle. This segmentation allows different functions to be displayed on different zones (e.g., main display on one zone, keypad on another), enhancing versatility while managing complexity through modular control.
Solution Approach 2:
The system dynamically configures the multiple display zones based on the detected folding angle. The control unit adjusts which zones are active and how they are utilized, allowing the device to adapt its functionality to the current folding state without requiring permanent complex hardware configurations for all possible functions.
