Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all electronic components (microcontroller, sensors, GPS, speaker, sound pickup device) are integrated on the main body of the smart glasses, then the smart glasses can provide complete intelligent functions, but the weight increases and power consumption increases
Solution Approach 1:
The patent divides the smart glasses system into two parts: a lightweight main body containing only essential components (frame, temples, sound pickup device), and an external mobile terminal containing the heavy electronic components (microcontroller, sensors, GPS, speaker). This segmentation transfers weight and processing burden to the mobile terminal while maintaining full functionality.
Solution Approach 2:
The mobile terminal serves multiple functions: it acts as both a speaker for audio output and a processing unit for voice recognition and beamforming calculations. This multi-functionality eliminates the need for dedicated hearing aid components, reducing overall system weight while maintaining versatility.
2Adaptability or versatility
If all electronic components are integrated on the main body of the smart glasses, then complete intelligent functions are achieved, but power consumption increases
Solution Approach 1:
The patent segments power-intensive processing tasks (voice recognition, beamforming calculations, GPS positioning) from the smart glasses main body and relocates them to the mobile terminal. Only lightweight audio capture and wireless communication remain in the glasses, dramatically reducing power consumption while preserving all intelligent functions.
Solution Approach 2:
The wireless communication module acts as an intermediary, transferring audio data and control signals between the smart glasses and mobile terminal. This allows the mobile terminal to handle complex processing tasks without requiring equivalent processing power in the glasses, reducing energy requirements.
3Volume of moving object
If electronic components are placed close together on the main body to save space, then device compactness is improved, but interference between components increases causing echo and howling
Solution Approach 1:
The patent extracts the speaker component from the smart glasses main body and relocates it to the mobile terminal. This physical separation eliminates the acoustic feedback loop between the speaker and sound pickup device, completely preventing echo and howling issues while maintaining compact glasses design.
4Adaptability or versatility
If additional hearing aid devices are installed on smart glasses to provide hearing aid functions, then functionality is improved, but weight and manufacturing cost increase
Solution Approach 1:
The mobile terminal is designed to provide both speaker functionality and hearing aid functionality through software-based voice recognition and beamforming processing. This universal approach eliminates the need for separate hearing aid hardware, reducing weight while maintaining full functionality.
Solution Approach 2:
Instead of installing dedicated hearing aid hardware, the patent uses software algorithms (beamforming, voice recognition) running on the mobile terminal to replicate hearing aid functionality. This virtual copying of hearing aid capabilities avoids additional physical components.
