Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple signal processing devices are used for multiple displays, then display functionality and versatility are improved, but resource management efficiency deteriorates
Solution Approach 1:
The system segments signal processing functions across multiple independent signal processing devices, each capable of processing data for specific displays. This segmentation allows flexible allocation of processing tasks while maintaining efficient resource utilization through the master-slave architecture and inter-device data sharing mechanisms.
2Device complexity
If multiple signal processing devices operate independently, then device complexity is reduced, but data sharing and synchronization capability deteriorates
Solution Approach 1:
The system introduces a master signal processing device as an intermediary that coordinates data sharing and synchronization among multiple slave signal processing devices. The master device manages data distribution and ensures consistent information flow across all displays, enabling efficient collaboration while preserving device independence.
3Adaptability or versatility
If different operating systems are used on signal processing devices, then system adaptability and versatility are improved, but communication compatibility and data exchange efficiency deteriorates
Solution Approach 1:
The system implements a universal communication framework that enables data exchange between signal processing devices running different operating systems. The master-slave architecture with standardized data sharing protocols allows devices with diverse OS environments to communicate efficiently, achieving cross-platform compatibility without sacrificing communication speed.
