Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the master device performs all audio transmission operations, then audio output reliability is improved, but battery consumption increases
Solution Approach 1:
The patent divides the audio transmission system into a master device and a slave device, where the master device receives audio data from the audio source device and transmits it to the slave device through wired or wireless communication. This segmentation allows the slave device to independently output audio, reducing the master device's operational burden and battery consumption while maintaining reliable audio output through coordinated operation between devices
Solution Approach 2:
The patent introduces a communication interface as an intermediary between the master device and slave device, enabling audio data transmission through wired or wireless links. This intermediary mechanism allows the slave device to receive audio data without requiring continuous active transmission from the master device, thereby reducing the master device's energy consumption while maintaining audio output reliability through the communication bridge
2Stability of the object's composition
If the slave device continuously monitors wired communication link status, then audio playback continuity is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the slave device monitors the status of the wired communication link between the master and slave devices. When the wired link is disconnected, the slave device switches to receiving audio data wirelessly from the master device. This feedback-based switching maintains audio playback continuity while using straightforward status detection and switching logic, avoiding excessive device complexity
Solution Approach 2:
The patent creates a dynamic communication system where the slave device can switch between wired and wireless reception modes based on real-time link status. The system transitions from a static wired-only connection to a dynamic multi-mode connection, ensuring continuous audio playback by adapting the communication path according to the actual link state without requiring overly complex monitoring infrastructure
3Manufacturing precision
If the master device transmits audio data continuously, then audio output quality is improved, but energy consumption increases
Solution Approach 1:
The patent segments the audio transmission function between master and slave devices, where the master device transmits audio data to the slave device which then outputs it. This segmentation allows the master device to transmit audio data less intensively compared to handling all audio processing itself, reducing energy consumption while maintaining audio output quality through the collaborative master-slave architecture
Solution Approach 2:
The patent employs a copying mechanism where the slave device receives a copy of the audio data from the master device through wired or wireless communication and outputs it independently. This copying approach allows the audio output function to be distributed, reducing the master device's energy consumption while preserving audio output quality through the replicated audio signal path
