Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If loudspeaker systems are connected to external PC for optimization, then optimization precision can be achieved, but setup complexity and time increase
Solution Approach 1:
The loudspeaker system performs self-optimization by determining its own control parameters based on input parameters from the user interface, eliminating the need for external PC connection. The processor within the loudspeaker executes optimization routines autonomously, allowing the system to serve itself without external assistance.
Solution Approach 2:
The optimization functionality is segmented into the individual loudspeaker unit, with each speaker containing its own processor and control system. This allows each loudspeaker to independently determine its control parameters without requiring centralized external control, distributing the optimization capability across the system.
2Manufacturing precision
If loudspeaker systems are connected to external PC for optimization, then fine-tuning can be achieved, but setup time increases
Solution Approach 1:
The loudspeaker system performs self-optimization by determining its own control parameters based on input parameters from the user interface, eliminating the need for external PC connection. The processor within the loudspeaker executes optimization routines autonomously, allowing the system to serve itself without external assistance.
Solution Approach 2:
The loudspeaker system is pre-equipped with the necessary processor and control algorithms to perform optimization routines independently. This preliminary preparation allows the system to execute fine-tuning immediately upon receiving input parameters, without requiring subsequent external PC connection for optimization.
3Ease of operation
If loudspeaker systems use self-contained control systems, then ease of operation improves, but device complexity increases
Solution Approach 1:
The control system merges the processor, user interface, and optimization algorithms into a single integrated unit within the loudspeaker. This combination consolidates multiple functions into one device, improving ease of operation by eliminating the need for separate external control equipment while managing complexity through integration.
Solution Approach 2:
The control system is designed to perform multiple functions including receiving input parameters, executing optimization routines, determining control parameters, and communicating with adjacent loudspeakers. This multi-functionality consolidates what would traditionally require separate devices into a single universal control unit within each loudspeaker.
