Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multifunction operating system with multiple function displays and operating elements is used to operate various devices, then the versatility and functionality are improved, but the device complexity and user interface complexity increase
Solution Approach 1:
The display surface is divided into at least two separate display areas, where the first display area shows a user interface for device operation while the second display area shows image data from the image capturing unit. This segmentation allows independent optimization of each area's function, reducing overall interface complexity while maintaining versatility.
Solution Approach 2:
The system introduces an automatic device selection mechanism that acts as an intermediary between the user and multiple devices. The control unit automatically selects the appropriate device based on detected driving states, eliminating the need for complex manual device selection interfaces while maintaining access to multiple functions.
2Adaptability or versatility
If complex function displays and operating elements are used to provide flexible device control, then the adaptability is improved, but the ease of operation deteriorates due to complex user interfaces
Solution Approach 1:
The control unit automatically selects the appropriate device based on pre-defined driving states before the user needs to operate it. This preliminary automatic selection simplifies the user's task to merely interacting with the interface for the already-selected device, maintaining flexibility while improving ease of operation.
Solution Approach 2:
The system continuously detects the current driving state and provides feedback by automatically adjusting which device is active and how the display areas are configured. This real-time feedback loop allows the interface to adapt to changing conditions without requiring complex user input, balancing versatility with operational simplicity.
3Ease of operation
If the driver needs to pay attention to operating various devices, then the ease of operation is improved through direct control, but the safety deteriorates due to driver distraction
Solution Approach 1:
The system performs automatic device selection based on detected driving states without requiring driver intervention. The operating system serves itself by autonomously determining which device should be active in which driving state, allowing the driver to operate the selected device with minimal attention while maintaining safety.
Solution Approach 2:
The system changes operational parameters automatically based on driving state detection. By detecting parameters such as vehicle motion state and automatically adjusting device selection and display configuration accordingly, the system maintains ease of operation for the relevant device while minimizing the driver's attention requirements.
4Ease of operation
If separate physical controls are used for each device function, then the ease of operation is improved through dedicated controls, but the device complexity increases
Solution Approach 1:
A single touch-sensitive display surface serves multiple functions by displaying different user interfaces for different devices in different driving states. This universal interface replaces multiple separate physical controls, reducing device complexity while maintaining ease of operation through context-appropriate device selection and interface presentation.
