Engineering Contradiction Analysis
1Adaptability or versatility
If navigation information is displayed on a mobile terminal mounted on a steering wheel, then navigation functionality is provided, but function operation screen and information providing screen cannot be simultaneously supported according to rotation of the mobile terminal
Solution Approach 1:
The system dynamically adjusts the display mode between landscape and portrait orientations based on the mobile terminal's rotation state. When the terminal is rotated, the processor detects the rotation and automatically switches the display orientation to maintain optimal viewing and interaction experience, making the system adaptable to different user positions and steering wheel angles.
Solution Approach 2:
The patent utilizes the rotational dimension of the mobile terminal as an additional control parameter. By detecting rotation around the vertical axis, the system transitions between two distinct display dimensions (landscape and portrait modes), enabling different screen layouts and interaction paradigms based on the terminal's angular position.
2Adaptability or versatility
If the mobile terminal is rotated together with the steering wheel, then the terminal follows steering wheel rotation, but it is difficult to distinguish between intentional rotation and steering wheel rotation
Solution Approach 1:
The system implements feedback mechanisms by monitoring steering wheel rotation data and comparing it with mobile terminal rotation data. When the terminal rotates in sync with the steering wheel, the system receives feedback indicating this correlated movement and suppresses mode switching. Only when rotation occurs independently of steering wheel movement does the system interpret it as user intention and trigger display mode changes.
Solution Approach 2:
The patent introduces steering wheel rotation information as an intermediary parameter to mediate between terminal rotation and mode switching decisions. By using this intermediate data layer, the system can filter out rotations caused by steering wheel movement and distinguish them from intentional user rotations, preventing false mode changes.
