Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth or Wi-Fi networks are used for vehicle communication, then data transmission can be achieved, but network setup time is increased and network availability becomes a constraint
Solution Approach 1:
The patent extracts communication from network-dependent protocols (Bluetooth, Wi-Fi) and implements it using the vehicle's existing audio interface and horn speaker. This removes the need for network setup and makes communication available independently of network availability, directly resolving the contradiction between communication reliability and setup time.
Solution Approach 2:
The system uses the vehicle's own audio interface and horn speaker for communication, eliminating dependency on external networks. The horn speaker serves dual purposes: its traditional alert function and data transmission, making the system self-sufficient and immediately available without network configuration.
2Reliability
If licensed spectra are used for vehicle communication, then communication reliability is improved, but signal interference from other devices increases
Solution Approach 1:
The patent changes the communication parameter from licensed radio frequency spectra to acoustic frequency spectra through the horn speaker. This parameter change shifts the domain from electromagnetic waves to sound waves, eliminating interference from other radio frequency devices while maintaining communication reliability through the vehicle's existing audio infrastructure.
3Measurement precision
If custom audio interfaces are designed for upper frequency communication, then communication precision is improved, but device complexity increases
Solution Approach 1:
The patent makes the vehicle's existing audio interface and horn speaker perform multiple functions: traditional audio output and data transmission. By encoding data in audio signals within the existing audio framework, the system achieves precise data transmission without requiring custom hardware interfaces, thus maintaining universality and avoiding increased device complexity.
Solution Approach 2:
The patent merges data transmission functionality with the existing audio output system. The horn speaker combines its alert function with data transmission by modulating audio signals, eliminating the need for separate custom interfaces and reducing overall system complexity while maintaining transmission accuracy.
