Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional motion sickness detection technology uses only limited vibration information, then the device complexity is reduced, but the measurement precision of motion sickness detection deteriorates
Solution Approach 1:
The detection system is segmented into multiple independent sensor modules: vibration sensors for motion detection, visual sensors for environment capture, and biosensors for physiological monitoring. Each sensor type independently collects specific data, and the processor integrates these segmented information streams to achieve comprehensive motion sickness detection with high precision while maintaining manageable device complexity.
Solution Approach 2:
The processor serves multiple functions: it processes vibration sensor data, analyzes visual environment images, integrates biosensor physiological signals, and generates personalized feedback. This multi-functional approach consolidates what could be separate complex systems into a single universal processing unit, improving measurement precision without proportionally increasing overall device complexity.
2Ease of operation
If anti-motion sickness patches are used, then the ease of operation is improved, but the reliability of motion sickness reduction deteriorates
Solution Approach 1:
The system continuously monitors the passenger's motion sickness state through multiple sensors and provides real-time personalized feedback through visual displays and tactile vibrations. This closed-loop feedback mechanism dynamically adjusts the intervention strategy based on actual physiological responses, ensuring reliable motion sickness reduction while maintaining ease of operation through automated control.
Solution Approach 2:
The system changes multiple parameters simultaneously: visual display parameters (content, brightness, position), tactile vibration parameters (frequency, intensity, pattern), and environmental control parameters (air conditioning). By dynamically adjusting these parameters based on real-time sensor data, the system achieves reliable motion sickness reduction tailored to each passenger's specific condition while requiring minimal user input.
3Measurement precision
If multiple sensors and biosensors are used to collect state information, then the measurement precision of passenger state detection is improved, but the device complexity increases
Solution Approach 1:
Multiple sensor types (vibration sensors, visual sensors, biosensors) and their processing functions are merged into an integrated system managed by a single processor. The processor unifiedly handles data fusion from all sensors, coordinate transformation, and feedback generation, reducing the complexity that would arise from separate independent systems while maintaining high measurement precision through comprehensive multi-sensor data integration.
