Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no audio output switching function is provided, then the device complexity remains low, but the ease of operation deteriorates as users cannot conveniently switch audio output devices
Solution Approach 1:
The patent applies preliminary action by proactively detecting the current audio output device and pre-configuring switching options before the user needs to switch. The system automatically identifies the voice interface object and determines available audio output devices, presenting switching options to the user before they actually need to make a change, thus making the switching process more convenient without adding complex manual configuration steps
Solution Approach 2:
The patent uses an audio output switching interface as an intermediary between the user and multiple audio output devices. This intermediary component detects the current voice interface object, identifies connected audio output devices, and presents a simplified switching mechanism that abstracts away the complexity of directly managing multiple audio devices, thereby improving ease of operation while maintaining manageable system complexity
2Adaptability or versatility
If audio output switching is always available, then the adaptability improves, but the device complexity increases due to always-on switching interface
Solution Approach 1:
The patent applies dynamics by making the audio output switching interface conditional rather than static. The switching interface is dynamically displayed only when a voice interface object is detected on the screen, and is hidden when no voice interface object is present. This dynamic behavior provides adaptability to different audio scenarios while avoiding the complexity of an always-on switching interface, as the interface automatically adjusts its visibility based on the current context
Solution Approach 2:
The system performs preliminary detection of voice interface objects and audio output device connections before deciding whether to display the switching interface. This preliminary action ensures that the switching functionality is only activated when needed, providing adaptability to different scenarios while maintaining low interface complexity by keeping the switching interface hidden during non-audio scenarios
Data Source
AI summary
A method for switching an audio output device includes after a predetermined event is captured on the information output interface, detecting whether a voice interface object representing a voice message is currently displayed on the information output interface. The method further includes detecting whether an external audio output device is currently connected to the mobile electronic apparatus. If it is detected that a voice interface object is currently displayed, and it is not detected that an external audio output device is connected to the mobile electronic apparatus, displaying an interface switching object on the information output interface, to correspondingly switch an audio output device of the mobile electronic apparatus according to an input operation of a user.
