Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If supplementary wires for data bus are installed in light trunking system, then data communication capability is improved, but installation effort and complexity increase significantly
Solution Approach 1:
The existing electrical lines in the light trunking system are made to serve dual purposes: both power transmission and data communication. The Power Line Communication interface enables the electrical lines to carry both AC power and modulated data signals, eliminating the need for separate data bus wires and reducing installation complexity while maintaining data communication capability
Solution Approach 2:
The communication adaptor merges the power transmission function and data communication function into a single integrated device. By combining the Power Line Communication interface, additional interface, and data converter into one adaptor that interfaces with the existing electrical lines, the system consolidates multiple functions without requiring separate wiring infrastructures
2Adaptability or versatility
If traditional data bus installation is used, then data communication is enabled, but installation cost increases
Solution Approach 1:
The system uses the existing electrical infrastructure to provide data communication services without requiring additional dedicated data communication wiring. The electrical lines that are already installed for power supply are made to serve themselves by carrying both power and data, eliminating the need for separate data bus installation and reducing overall installation costs
Solution Approach 2:
The electrical lines are designed to perform multiple functions simultaneously - power transmission and data communication. This multi-functionality allows the system to achieve data communication capability using the existing electrical infrastructure, avoiding the need for additional data bus wires and reducing installation costs
3Speed
If Power Line Communication interface is integrated, then communication speed is enhanced to Gbps range, but device complexity increases
Solution Approach 1:
The communication adaptor is divided into distinct functional modules: Power Line Communication interface for high-speed data modulation/demodulation, additional interface for standard communication protocols, and data converter for protocol translation. This segmentation allows each module to be optimized independently while working together to achieve Gbps communication speeds without overwhelming system complexity
Solution Approach 2:
The data converter acts as an intermediary between the Power Line Communication interface and the additional interface, translating between different data protocols. This intermediary component enables high-speed PLC communication to be seamlessly integrated with standard communication protocols, achieving Gbps speeds while maintaining compatibility with existing systems
