Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an application program with exclusive rights is operated, then the reliability of sound output control is improved, but the adaptability to switch between different application programs deteriorates
Solution Approach 1:
The patent implements dynamic switching of application programs based on foreground/background status. The system allows flexible transition between applications with exclusive rights and other applications, enabling the sound output control to adapt dynamically to different operational contexts while maintaining reliability through structured switching mechanisms.
Solution Approach 2:
The patent performs preliminary actions by switching application programs to background before stopping their sound playback. This ensures that exclusive right applications are properly deactivated and resources are freed up before transitioning to new applications, maintaining system reliability during switching operations.
2Ease of operation
If communication control is limited to specific protocols, then the ease of operation is improved, but the adaptability to communicate with different onboard devices deteriorates
Solution Approach 1:
The patent implements a universal communication control mechanism that can handle multiple communication protocols. The switching unit and sound control unit are designed to work with different protocol types, allowing the system to maintain ease of operation while adapting to various onboard devices regardless of their specific communication protocols.
3Ease of operation
If manual selection of audio data is required, then the ease of operation is worsened, but the adaptability to handle different audio sources is improved
Solution Approach 1:
The patent implements self-service functionality where the sound control unit automatically identifies and switches between audio sources based on application program status. The system autonomously handles audio data selection by monitoring foreground/background application states and automatically transitioning audio playback without requiring manual user intervention, thus improving ease of operation while maintaining adaptability to multiple audio sources.
Data Source
AI summary
A mobile terminal that performs communication with an onboard device includes: a communication control unit configured to control reception of information instructing to switch a sound source which is transmitted from the onboard device, the information including information indicating an application program which is executed in the terminal serving as the sound source, and transmission of a sound, played by an application program operating in a foreground of the terminal, to the onboard device; a switching unit configured to switch an application program having been in operation in a foreground until immediately before, to a background, on the basis of the received information instructing to switch a sound source, and to switch an application program having been in operation in a background until immediately before, to a foreground; and a sound control unit configured to stop playing a sound of the application program having been in operation in a foreground until immediately before, and to start playing a sound of the application program having been in operation in a background until immediately before, subsequently to the stop.
