Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple units with mixers and specific docking stations are used to enable multiple musicians to perform together, then the capability for multiple users to perform music together is improved, but the device complexity increases
Solution Approach 1:
The patent implements universality by designing a single signal processing device that can serve multiple functions: it acts as both a signal source and a mixer for multiple users. The device includes multiple connecting terminals that can be connected to different users' sound emitting devices, allowing one device to replace multiple specialized units while maintaining the capability for multiple musicians to perform together.
Solution Approach 2:
The patent merges the functions of multiple separate units into a single integrated signal processing device. Instead of requiring separate units for each musician with dedicated mixers and docking stations, the invention combines all these functions into one device that can connect to multiple users simultaneously through its multiple connecting terminals, thereby reducing overall system complexity.
2Adaptability or versatility
If a mixer is mounted to each unit to combine audio signals, then the audio signal mixing capability is improved, but the device complexity and cost increase
Solution Approach 1:
The single signal processing device performs the mixing function universally for all users through its analog bus architecture. The mixer functionality is integrated into the main device rather than being distributed to each user unit, allowing one device to handle audio signal combining for multiple musicians without requiring separate mixers at each endpoint.
Solution Approach 2:
The mixing function is extracted from individual user units and consolidated into the central signal processing device. By taking the mixer capability out of each separate unit and placing it in the main device, the system reduces the total number of mixers required while maintaining the ability to combine audio signals from multiple users effectively.
3Adaptability or versatility
If audio signals are supplied to other units via different paths, then the audio signal distribution capability is improved, but the configuration complexity increases
Solution Approach 1:
The analog bus provides a universal signal distribution pathway that can connect to multiple users simultaneously. Instead of requiring complex different paths for each user, the single analog bus structure serves all users, simplifying the signal distribution architecture while maintaining the capability to supply audio signals to multiple sound emitting devices.
Solution Approach 2:
The signal distribution is segmented into a central analog bus that handles all user connections. This segmentation allows the complex distribution function to be managed through a single centralized pathway rather than multiple separate paths, reducing configuration complexity while maintaining multi-user capability.
