Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wearable device displays static visual objects without real-time updates, then the device complexity is reduced, but the user experience and interactivity are limited
Solution Approach 1:
The patent introduces an external electronic device as an intermediary that houses the sensor and handles complex data processing. The wearable device communicates with this external device to obtain sensor information and update visual objects, thereby achieving real-time interactivity without embedding complex sensor systems directly in the wearable device.
Solution Approach 2:
The external electronic device serves multiple functions: it acts as a communication partner, a sensor host, and a data processing unit. By leveraging the multi-functionality of the external device, the wearable device can achieve enhanced interactivity without proportionally increasing its own complexity.
2Productivity
If the wearable device continuously updates visual objects in real-time, then the user experience is enhanced, but the loss of time for data communication increases
Solution Approach 1:
The system establishes communication links and retrieves sensor information in advance or on-demand before visual object updates are needed. This preliminary action reduces the latency during actual update moments, enabling real-time user experience while minimizing communication time overhead.
Solution Approach 2:
The wearable device implements a feedback mechanism where visual objects are updated based on received sensor information from the external device. This closed-loop feedback system ensures that updates occur only when necessary, optimizing the balance between real-time performance and communication efficiency.
3Measurement precision
If the wearable device includes integrated sensors for dynamic updates, then the measurement precision is improved, but the weight of the wearable device increases
Solution Approach 1:
The patent extracts the sensor component from the wearable device and places it in an external electronic device. The wearable device communicates with the external device to obtain sensor data, thereby achieving accurate measurements without the weight penalty of integrated sensors.
Solution Approach 2:
Instead of physically integrating sensors, the wearable device creates a data copy or representation of sensor information through communication with the external device. This virtual copying approach provides the necessary measurement precision without the physical weight of actual sensor hardware.
