Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If local processing is performed in digital glasses, then processing speed and responsiveness are improved, but power consumption increases
Solution Approach 1:
The processing system is segmented into multiple components: a low-power processor in the digital glasses handles basic functions and sensor data, while a remote high-power processor handles intensive graphics rendering and complex computations. This segmentation allows each processor to operate at its optimal power level, resolving the contradiction between processing speed and power consumption.
Solution Approach 2:
A wireless communication intermediary transmits data and rendered content between the digital glasses and the remote processing system. This intermediary enables the glasses to offload intensive processing tasks without requiring local high-power hardware, thus maintaining fast processing performance while minimizing power consumption at the wearable device.
2Productivity
If high-performance graphics processing is performed locally, then visual quality and rendering performance are improved, but battery life decreases
Solution Approach 1:
The high-performance graphics processing function is extracted from the digital glasses and relocated to a remote processing system. The glasses retain only the essential display and sensor functions, while the intensive rendering tasks are performed remotely and the results are transmitted back for display. This extraction preserves high rendering performance while extending battery life by eliminating power-hungry local processing hardware.
3Adaptability or versatility
If wireless communication range is extended, then connectivity and accessibility are improved, but power consumption increases
Solution Approach 1:
The wireless communication system uses partial action by transmitting only essential data packets and utilizing power-saving communication modes. The system maintains extended connectivity range through intelligent signal management and selective transmission, rather than continuous high-power communication, thus achieving broad accessibility while controlling power consumption.
