Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vibration is generated through a consistent generation method, then the vibration delivery is simple and reliable, but it does not adapt to the driver's physical state or emotion
Solution Approach 1:
The vibration generation system transitions from a static, consistent generation method to a dynamic system that continuously adapts to the driver's physical state and emotion. The system adjusts vibration characteristics in real-time based on detected driver conditions, making the previously fixed system flexible and responsive to changing states.
Solution Approach 2:
The system incorporates feedback mechanisms by detecting the driver's physical state and emotion through sensors and analysis devices. This feedback loop enables the vibration generation device to receive information about the driver's condition and adjust its output accordingly, creating a closed-loop adaptive system.
2Adaptability or versatility
If vibration warning is generated in steering wheels, then the warning function is provided, but it still does not consider the driver's physical state or emotion
Solution Approach 1:
The system performs preliminary detection and analysis of the driver's physical state and emotion before generating vibration warnings. By analyzing driver conditions in advance and continuously monitoring them, the system prepares appropriate vibration responses based on the detected state, ensuring that warnings are tailored to the driver's current condition.
3Measurement precision
If multiple types of driver state information are analyzed, then the personalization of vibration signals is improved, but the complexity of information processing increases
Solution Approach 1:
The state analysis device is divided into multiple specialized analysis devices, each responsible for processing a specific type of driver state information (image analysis device for facial expressions, voice analysis device for vocal characteristics, biometric signal analysis device for physiological data). This segmentation allows each component to focus on a specific analysis task, improving overall precision while managing complexity through modular design.
Solution Approach 2:
The state analysis device is designed as a multi-functional system that can process multiple types of driver state information simultaneously. By creating a universal analysis platform capable of handling various input types (images, voice, biometric signals), the system achieves comprehensive driver state monitoring without requiring entirely separate systems for each analysis type.
