Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wireless communication technology is used for stage sound devices, then wireless mobility is achieved, but signal transmission speed is slow and audio data is easy to lose due to long distances between devices
Solution Approach 1:
The patent segments the wireless communication process into multiple stages: initial connection phase using 5.8 GHz for reliable pairing, and data transmission phase using BLUETOOTH for stable audio streaming. This segmentation allows each protocol to operate in its optimal performance zone, resolving the contradiction between wireless mobility and transmission reliability.
Solution Approach 2:
The control device acts as an intermediary that coordinates between 5.8 GHz communication and BLUETOOTH communication. It manages the dual-protocol system, initiating 5.8 GHz connection first, then establishing BLUETOOTH relay connections for actual audio data transmission, ensuring both mobility and reliability are maintained.
2Speed
If 5.8 GHz frequency band is used for wireless communication, then data transmission speed is improved, but signal strength decreases over long distances
Solution Approach 1:
The system performs preliminary connection establishment using 5.8 GHz frequency band to create a reliable communication channel before actual audio data transmission. This preliminary action ensures that the high-speed 5.8 GHz connection is secured first, then BLUETOOTH relays are activated to maintain signal strength over distance.
Solution Approach 2:
The communication system dynamically switches between 5.8 GHz direct connection and BLUETOOTH relay connection based on distance and signal conditions. When devices are close, 5.8 GHz provides high-speed transmission; when distance increases, BLUETOOTH relays dynamically extend the communication range while maintaining acceptable signal strength.
3Adaptability or versatility
If multiple speaker devices are connected wirelessly, then system scalability is improved, but communication interference increases
Solution Approach 1:
The patent segments the communication spectrum by using 5.8 GHz for control and connection management while BLUETOOTH handles audio data transmission. This segmentation allows multiple speaker devices to operate simultaneously without interference, as each protocol operates on different frequency bands and serves different functions.
Solution Approach 2:
The control device serves as a central intermediary that coordinates communication among multiple speaker devices. It manages channel allocation, assigns BLUETOOTH relay connections, and prevents interference by orchestrating the communication schedule and resource distribution across all connected devices.
