Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional intercom devices are used in noisy environments, then voice communication can be established, but ambient noise causes great interference and users cannot hear the contents clearly
Solution Approach 1:
The patent segments the audio signal processing into multiple components: ambient noise detection through microphones, bone conduction signal transmission through the skull, and selective noise filtering. This segmentation allows the system to isolate and process different audio frequencies separately, effectively reducing ambient noise interference while maintaining clear voice communication.
Solution Approach 2:
The patent introduces bone conduction as an intermediary transmission path between the speaker and the user's auditory system. Instead of relying solely on air conduction (which is vulnerable to ambient noise), the system uses bone conduction to directly transmit voice signals through the skull to the inner ear, bypassing the external ear canal where ambient noise enters.
2Adaptability or versatility
If traditional intercom devices are used, then group communication is enabled, but confidentiality of voice communications is weak
Solution Approach 1:
The patent segments communication into public and private channels. The intercom device maintains group communication capabilities through traditional microphones and speakers, while simultaneously enabling private confidential conversations through bone conduction. This segmentation allows users to choose the appropriate communication mode based on confidentiality requirements.
Solution Approach 2:
The patent applies different transmission qualities to different communication needs. Bone conduction provides a private, confidential channel for sensitive conversations, while traditional acoustic transmission serves public group communications. Each transmission path is optimized for its specific purpose, with bone conduction offering localized auditory experience that prevents eavesdropping.
3Adaptability or versatility
If traditional intercom devices are used, then communication function is provided, but voice communication mode is single and limits usage
Solution Approach 1:
The patent makes the intercom device universal by integrating multiple communication modes into a single system. The device can switch between traditional acoustic communication, bone conduction private communication, and hybrid modes. This multi-functionality allows the same device to serve various communication needs without requiring separate specialized equipment.
Solution Approach 2:
The patent merges bone conduction technology with traditional intercom functionality into a unified system. The bone conduction module is integrated with the existing microphone, speaker, and control systems, allowing seamless switching between communication modes. This combination maintains device simplicity while expanding functional versatility.
