Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all-in-one smart glasses with integrated battery and computing unit are used, then the structure is simple and convenient to wear, but the weight is too heavy and battery life is too short
Solution Approach 1:
The smart glasses system is divided into two independent parts: lightweight glasses body and separate wearable battery pack. The glasses body contains only essential components (display, frame, minimal electronics) while the battery pack houses the power source and computing unit. This segmentation allows the glasses to be worn comfortably without heavy batteries, while the battery pack can be detached or repositioned as needed.
2Reliability
If thick power and data transmission lines are used to connect split smart glasses, then power and data can be transmitted reliably, but the lines interfere with head movements and are inconvenient to wear
Solution Approach 1:
The patent replaces traditional mechanical cable connections with wireless communication technologies. Power transmission is achieved through wireless charging (inductive or resonant coupling), while data transmission uses wireless protocols (Bluetooth, Wi-Fi). This eliminates the mechanical constraints of thick cables, allowing free head movement without interference from transmission lines.
3Device complexity
If traditional microphones are used for voice input, then the structure is simple, but voice input is ineffective in noisy environments and compromises privacy
Solution Approach 1:
The patent implements differentiated audio capture zones with specialized microphone characteristics. Close-talking microphones with directional patterns are positioned near the user's mouth to capture whisper-voice with high sensitivity. Remote microphones with omnidirectional patterns capture ambient sound for noise reference. The system applies local signal processing tailored to each microphone's position and function, enhancing whisper detection while suppressing background noise.
Solution Approach 2:
The patent introduces bone conduction sensors as an intermediary channel for voice input. These sensors detect vibrations from the user's skull bones caused by whisper-voice, providing a direct mechanical coupling that bypasses air conduction interference from environmental noise. This intermediary pathway enables reliable voice capture in noisy settings while maintaining privacy, as bone conduction signals are not picked up by external microphones.
4Reliability
If normal voice input is used in public places, then communication is clear, but it disturbs others and compromises privacy
Solution Approach 1:
The patent uses bone conduction sensors as an intermediary transmission channel that bypasses air conduction. Whisper-voice vibrations are transmitted directly through the skull bones to the sensors, creating a private communication channel that does not radiate sound waves into the environment. This allows clear communication between user and device without disturbing others or compromising privacy in public settings.
Solution Approach 2:
The patent employs acoustic isolation elements (flexible acoustic seals or damping materials) around the traditional microphones and speakers. These elements create acoustic barriers that contain sound waves, preventing whisper-voice from leaking outward to disturb others while maintaining communication clarity through the bone conduction pathway.
