Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all vehicle data is uploaded to the remote system, then complete data analysis is achieved, but data transmission size and cost increase significantly
Solution Approach 1:
The system extracts only the essential physiological parameters (heart rate, temperature, facial expressions) from the driver and uses these to selectively trigger data uploads. This extraction principle allows the system to avoid transmitting unnecessary data while ensuring critical information is captured when driver physiological events occur.
Solution Approach 2:
The patent applies local quality by making the data transmission selective rather than uniform. Different data transmission behaviors are applied based on local conditions - specifically, whether a physiological event is detected. When events occur, relevant data is uploaded; when they don't, transmission is minimized. This creates differentiated data handling based on local physiological states.
2Reliability
If all vehicle data is transmitted to the remote system, then comprehensive analysis is enabled, but transmission cost increases
Solution Approach 1:
The system performs preliminary detection of driver physiological events before triggering data transmission. By monitoring physiological parameters in advance and using them as triggers, the system ensures that data is transmitted only when relevant events occur, thereby maintaining analysis accuracy while reducing unnecessary transmission costs.
Solution Approach 2:
The system uses feedback from physiological sensor data to control data transmission behavior. The physiological events detected serve as feedback signals that trigger or suppress data uploads to the remote system. This feedback mechanism ensures transmissions occur based on actual driver states rather than continuously, optimizing both reliability and cost.
3Productivity
If physiological sensors are added to detect driver events, then selective data upload is enabled, but device complexity increases
Solution Approach 1:
The physiological sensors serve multiple functions: detecting driver stress, fatigue, and other physiological states that can trigger data uploads. This multi-functionality allows a single sensor system to support various triggering conditions without requiring separate detection mechanisms for each type of event, thereby managing complexity while maintaining productivity.
4Loss of energy
If data transmission is reduced to save cost, then transmission efficiency improves, but data availability for analysis decreases
Solution Approach 1:
The system uses the driver's own physiological data to determine when vehicle data should be uploaded. The physiological sensors continuously monitor the driver and automatically trigger transmissions based on detected events without requiring external control. This self-service mechanism ensures data is available when needed while minimizing unnecessary transmissions, balancing cost savings with data availability.
Data Source
AI summary
The systems and methods provided herein are directed to the uploading and transmission of vehicle data to a remote system when a physiological event for a driver has been detected using one or more sensors. Information such as the driver's heart rate, temperature, voice inflection or facial expression may be monitored to detect the physiological event. Vehicle data, such as gathering or control system data, may be sent once the event has been detected. Selected vehicle data associated with the event or all data during the time of the event may be sent. After receiving the vehicle data, the remote system may process or store it where it may be used to modify automated driving functionalities.
