Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are used for audio transmission, then audio distribution is achieved, but noise is generated due to potential difference problems, cable quality issues, interference, and physical damage risks
Solution Approach 1:
The patent replaces the mechanical cable-based audio transmission system with a wireless Bluetooth transmission system. The master device transmits audio signals wirelessly to slave devices, eliminating physical cables and their associated problems such as noise, interference, and physical damage. This substitution of mechanical transmission with electromagnetic wireless transmission resolves the technical contradiction by maintaining audio distribution functionality while removing harmful cable-related factors.
2Ease of operation
If FM radio broadcasting is used for audio transmission, then wireless audio distribution is achieved, but audio quality is compromised due to transmission bandwidth and noise problems
Solution Approach 1:
The patent introduces Bluetooth technology as an intermediary transmission medium between the audio source and reproducing devices. Instead of using FM radio broadcasting which has bandwidth and noise limitations, the system uses Bluetooth wireless transmission which provides dedicated communication channels, higher audio quality, and resistance to interference. This intermediary solution maintains the convenience of wireless distribution while significantly improving audio quality and reliability.
3Reliability
If multiple cables are used for connecting audio devices, then audio distribution is achieved, but installation becomes difficult to sort out and mobility is reduced
Solution Approach 1:
The patent replaces the complex mechanical cable connection system with a wireless Bluetooth connection system. Multiple audio devices can be connected wirelessly without physical cables, eliminating installation complexity and maintaining mobility. The master device can simultaneously connect to multiple slave devices wirelessly, providing stable audio distribution without the physical constraints of cable management.
4Reliability
If a wireless audio distribution system with master and slave configuration is implemented, then synchronized audio distribution is achieved, but system configuration complexity increases
Solution Approach 1:
The patent implements automatic master-slave device identification and connection establishment. When devices are powered on, they automatically detect each other, establish master-slave relationships, and begin synchronized audio distribution without manual configuration. The system performs self-configuration, reducing the complexity burden on users while maintaining reliable synchronized audio transmission across multiple devices.
