Engineering Contradiction Analysis
1Speed
If compute-intensive tasks are performed locally in wearable devices, then processing speed and responsiveness are improved, but device complexity and power consumption increase
Solution Approach 1:
The patent extracts compute-intensive tasks from the wearable device and relocates them to a remote server or cloud infrastructure. The wearable device retains only lightweight processing functions for immediate sensor data handling, while heavy computational workloads such as image processing, 3D rendering, and AI inference are performed remotely and results are transmitted back to the device.
2Measurement precision
If high-resolution data is transmitted over wireless links, then image quality and visual fidelity are improved, but bandwidth requirements and transmission power increase
Solution Approach 1:
The system performs preliminary processing and compression of high-resolution data before transmission. Pre-processing operations such as noise filtering, feature extraction, and intelligent compression are executed either locally in the wearable device or at the edge server, reducing the volume of data that needs to be transmitted over the wireless link while preserving the essential visual information quality.
3Productivity
If more processing power is provided in wearable devices, then computational capability is improved, but device size and weight increase
Solution Approach 1:
The patent introduces a remote server or cloud infrastructure as an intermediary to handle computationally intensive tasks. This external computing resource acts as a mediator between the wearable device and the complex processing requirements, allowing the device to maintain a lightweight form factor while still accessing high computational capabilities when needed through wireless connectivity.
4Productivity
If wireless transmission power is increased, then data rate and communication range are improved, but power consumption and heat generation increase
Solution Approach 1:
The system employs adaptive transmission power control that applies partial action - transmitting at the minimum necessary power level to achieve the required data rate. Rather than continuously operating at maximum power, the system dynamically adjusts transmission power based on channel conditions, distance, and current data rate requirements, reducing unnecessary energy consumption and heat generation while maintaining adequate communication performance.
