Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch pad is used for input operations, then the device can control various vehicle functions, but the operation lacks intuitiveness and user feedback
Solution Approach 1:
The patent implements a feedback mechanism where the display shows visual indicators at positions corresponding to touch areas on the touch pad. When a user touches a specific area, the system provides immediate visual feedback on the display, creating a direct connection between user input and system response, thereby improving intuitiveness and reducing information loss.
Solution Approach 2:
The touch pad surface is divided into multiple distinct touch areas, each corresponding to specific functions or screen regions. This segmentation allows users to intuitively understand which area to touch for specific operations, improving ease of operation by making the interface more structured and predictable.
2Productivity
If the touch area is divided into multiple areas corresponding to operation screens, then navigation efficiency improves, but the device complexity increases
Solution Approach 1:
The touch pad is segmented into multiple functional areas, each mapped to specific screen regions or functions. This segmentation enables efficient navigation by allowing users to access different functions by touching different areas, improving productivity while the controller manages the complexity of mapping these areas to screen coordinates.
Solution Approach 2:
The controller is designed to handle multiple functions through a universal mapping mechanism that connects touch areas to screen coordinates dynamically. This multi-functionality allows the same hardware structure to support various operation modes and screen layouts, improving navigation efficiency without proportionally increasing device complexity.
3Ease of operation
If geometric feedback is provided on the screen corresponding to user gestures, then user experience improves, but the processing requirements increase
Solution Approach 1:
The system provides geometric feedback by displaying visual indicators at positions on the screen that correspond to the physical touch areas. This feedback mechanism enhances user experience by making the interface more responsive and intuitive, while the processing energy required is optimized by using simple coordinate mapping rather than complex image processing.
