Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS positioning and tracking are performed using traditional data communication services, then positioning functions can be accomplished in areas with good telecommunication infrastructure, but positioning and tracking cannot be accomplished in areas with poor telecommunication infrastructure
Solution Approach 1:
The patent replaces traditional electronic data communication (mechanical/electrical system) with acoustic signal transmission (acoustic system). The coordinate transmitter converts GPS coordinates into DTMF audio signals that can be transmitted through acoustic channels, enabling positioning in areas without telecommunication infrastructure. This substitution allows the system to operate in both traditional and infrastructure-poor environments.
Solution Approach 2:
The patent changes the transmission medium parameter from electromagnetic data signals to acoustic DTMF signals. By encoding coordinate information into audio frequency tones that can be transmitted through air or other physical media, the system gains adaptability to environments where traditional data communication is unavailable, while maintaining positioning reliability.
2Device complexity
If coordinate data is transmitted as raw data strings, then the data format is simple, but the data cannot be properly transmitted through acoustic channels due to special characters
Solution Approach 1:
The patent introduces an intermediary encoding process that converts raw coordinate data strings into DTMF audio signals. Special characters in the coordinate data are replaced with numeric equivalents that can be transmitted as acoustic tones. This intermediary transformation enables reliable transmission through acoustic channels while preserving the original coordinate information.
Solution Approach 2:
The patent changes the data representation parameter from raw text format to encoded numeric format suitable for acoustic transmission. By transforming the coordinate data into a format compatible with DTMF signal encoding, the system achieves both transmission reliability and maintains manageable data complexity through systematic encoding rules.
