Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wearable devices are integrated into extended reality service systems for motion data tracking, then user experience is improved, but device complexity increases
Solution Approach 1:
The system is divided into separate functional modules: wearable devices for motion data collection, trackers for positioning, and host devices for processing. This segmentation allows each component to specialize in specific functions, improving overall adaptability while managing complexity through modular design.
Solution Approach 2:
The wearable devices are designed to serve multiple functions: they can collect motion data for both extended reality applications and general fitness tracking. The detachable docking mechanism with trackers enables the same device to work in different configurations, enhancing versatility without proportionally increasing complexity.
2Measurement precision
If wearable devices collect motion data continuously, then tracking accuracy is improved, but energy consumption increases
Solution Approach 1:
The system employs periodic data transmission where motion data is collected continuously at the wearable device but transmitted to the host in periodic batches. This approach maintains tracking accuracy through continuous collection while reducing energy consumption by limiting active transmission to periodic intervals rather than continuous operation.
Solution Approach 2:
Motion data is pre-collected and buffered in the wearable device before transmission. This preliminary collection allows the device to operate in a low-power state for data acquisition while deferring energy-intensive transmission operations to scheduled moments, thus maintaining accuracy without sustained high energy consumption.
3Reliability
If wearable devices dock with trackers for data transmission, then tracking functionality is improved, but ease of operation deteriorates
Solution Approach 1:
The docking mechanism between wearable devices and trackers is designed to automatically recognize and establish connections when brought into proximity. The system performs self-alignment and data channel configuration without requiring manual setup, thereby improving reliability of tracking functionality while maintaining ease of operation through automatic connection establishment.
