Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a server network is used for audio signal sharing, then audio signal sharing can be achieved, but the system becomes complicated and costly
Solution Approach 1:
The patent extracts the audio signal sharing function from a complex server network and implements it locally through a hub device. The hub receives audio signals from one terminal and distributes them to multiple audio output devices directly, eliminating the need for complicated server infrastructure while maintaining the audio sharing capability.
Solution Approach 2:
The hub acts as an intermediary device between the terminal and multiple audio output devices. It receives audio signals from the terminal via a data interface and distributes them to connected audio devices, simplifying the system architecture by replacing the server network with a local mediation device.
2Adaptability or versatility
If multiple data interfaces are provided on terminals, then more devices can be connected, but the terminal structure becomes more complex
Solution Approach 1:
The patent merges multiple data interface functions into a single hub device. Instead of equipping each terminal with multiple data interfaces for different audio devices, the terminal uses one data interface to connect to the hub, which then provides connections to multiple audio output devices through its multiple ports.
Solution Approach 2:
The hub provides universal connectivity by supporting multiple types of audio output devices through a single connection point. It accepts one data interface connection from the terminal and provides multiple diverse connection options for various audio devices, making the system versatile without complicating the terminal itself.
3Adaptability or versatility
If a hub is introduced for audio sharing, then interface limitations are overcome, but the device complexity increases
Solution Approach 1:
The patent segments the audio sharing system into distinct functional modules: the terminal that generates audio signals, the hub that manages signal distribution, and multiple audio output devices that consume the signals. This segmentation allows each component to have a specific, simplified function while the overall system achieves high versatility.
