Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If commands are transmitted through instant messengers using existing APIs, then communication between devices is enabled, but direct command transmission to electronic devices is blocked due to API limitations
Solution Approach 1:
The patent uses audio signals as an intermediary medium to transmit commands. Instead of attempting to transmit commands directly through the restricted instant messenger API, the system converts commands into audio signals that can be played through the device's speaker and captured by another device's microphone, thereby bypassing the API limitation while maintaining reliable command delivery
Solution Approach 2:
The patent replaces the electronic data transmission mechanism (which is blocked by API restrictions) with an acoustic signal transmission mechanism. By encoding commands as audio frequencies that can be played and recorded, the system substitutes the blocked electronic communication path with an alternative acoustic path that achieves the same command transmission goal
2Adaptability or versatility
If audio signals are used to carry commands, then API limitations are bypassed, but signal extraction and decoding complexity increases
Solution Approach 1:
The patent employs periodic audio signals with specific frequency patterns to encode commands. By using regularly repeating waveforms with distinct characteristics for different commands, the system enables straightforward detection and decoding through simple frequency matching or pattern recognition, reducing the complexity of signal processing while maintaining versatile command transmission
Solution Approach 2:
The patent uses different audio frequency characteristics (analogous to color changes) to represent different commands. Each command is encoded with a unique frequency signature that can be easily identified through spectral analysis or frequency detection, allowing the system to handle multiple command types without increasing processing complexity significantly
