Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional VR headsets use traditional sensors only for head tracking and eye tracking, then the device complexity is kept low, but the measurement precision of biometric data is insufficient for healthcare applications
Solution Approach 1:
The patent combines multiple types of biometric sensors (EEG, EDA, PPG, temperature) with the existing VR headset tracking sensors into a single integrated device. This merging allows the VR headset to simultaneously perform head/eye tracking and healthcare-grade biometric monitoring, resolving the contradiction by achieving high measurement precision while managing device complexity through unified integration.
Solution Approach 2:
The VR headset is designed to serve multiple functions: traditional virtual reality immersion, head/eye tracking, and healthcare biometric monitoring. By making the device universal and multi-functional, the patent achieves high biometric data quality without proportionally increasing complexity, as the same physical platform supports diverse applications.
2Adaptability or versatility
If VR headsets integrate multiple types of biometric sensors (EEG, EDA, PPG, temperature), then the adaptability for healthcare applications is improved, but the device complexity increases
Solution Approach 1:
Multiple specialized sensors (EEG for brain activity, EDA for skin conductance, PPG for blood flow, temperature sensors) are merged into a single VR headset platform. This consolidation provides broad healthcare application adaptability while managing complexity through integrated design rather than separate devices.
Solution Approach 2:
The sensor fusion system automatically processes and integrates data from multiple sensor types without requiring manual intervention. The system self-manages the complexity of combining EEG, EDA, PPG, and temperature data streams, allowing high adaptability while keeping the user interface simple.
3Measurement precision
If sensors are strategically placed in optimal locations (temples, forehead, etc.), then the measurement precision of physiological data is improved, but the ease of manufacture decreases
Solution Approach 1:
Sensors are placed in specific optimal locations (temples for EEG, forehead for EDA/PPG, ears for temperature) where each sensor type can capture the highest quality physiological signals. This localized optimization of sensor placement improves measurement precision while the modular design helps manage manufacturing complexity.
Solution Approach 2:
The sensor positions are pre-determined and pre-configured during the manufacturing process according to optimal physiological measurement locations. By performing the precise placement action preliminarily during manufacturing rather than during use, the system achieves high measurement precision while simplifying the user experience.
