Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile devices are used to capture and coordinate audiovisual performances over wireless networks, then user accessibility and social interaction are improved, but computational resource consumption and network bandwidth requirements increase
Solution Approach 1:
The system divides computational tasks between mobile devices (audio/video capture and encoding) and server infrastructure (pitch correction, harmonization, and coordination). This segmentation allows mobile devices to maintain low resource consumption while still providing sophisticated audiovisual processing through cloud-based services.
Solution Approach 2:
A server infrastructure acts as an intermediary between multiple mobile devices, coordinating their audiovisual streams and performing computationally intensive processing. This mediator approach enables sophisticated processing without burdening individual mobile devices with high computational requirements.
2Measurement precision
If real-time pitch correction and harmonization are applied to vocal performances, then audio quality is improved, but processing time and computational load increase
Solution Approach 1:
The system performs preliminary encoding and preparation of audio signals on mobile devices before transmission, and executes real-time pitch correction and harmonization on the server side. This preliminary action approach ensures high audio quality processing without adding significant latency to the user experience.
3Adaptability or versatility
If multiple geographically distributed users participate in coordinated performances, then social interaction and content variety are improved, but network transmission latency and synchronization complexity increase
Solution Approach 1:
The server infrastructure serves as a central intermediary that receives, coordinates, and synchronizes audiovisual streams from multiple geographically distributed users. This mediator architecture manages synchronization complexity centrally, allowing users to interact socially without each device needing to independently handle complex synchronization protocols.
