Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signals are routed through traditional communication lines for satellite broadcasting, then signal transmission is achieved, but communication line interruptions can occur causing loss of signal integrity
Solution Approach 1:
A local area network (LAN) is introduced as an intermediary routing system between the encoder and multiplexer, replacing traditional communication lines. The LAN provides alternative transmission paths through multiple routers, ensuring that signal integrity is maintained even if one communication path fails. This mediator approach allows the system to bypass interrupted communication lines while maintaining continuous signal flow.
Solution Approach 2:
The signal transmission path is divided into multiple segmented routes through the LAN infrastructure. Instead of relying on a single communication line, the system segments the transmission into multiple possible paths through different routers and network nodes. This segmentation allows the system to isolate and bypass interrupted segments while maintaining overall signal integrity through alternative segments.
2Adaptability or versatility
If high definition television programming is provided to increase service quality, then subscriber viewing experience is enhanced, but system complexity and processing requirements increase
Solution Approach 1:
High definition television signals are encoded into transport streams before being routed through the LAN, preparing them in advance for multiplexing and transmission. This preliminary encoding action converts complex HD signals into standardized transport stream format, reducing processing complexity during subsequent routing and transmission phases while maintaining service quality.
3Reliability
If redundant routing paths are implemented to ensure continuous transmission, then reliability is improved, but device complexity increases
Solution Approach 1:
The local area network infrastructure is utilized for multiple functions: signal routing, error correction, and alternative path selection. By making the LAN multi-functional, the system achieves redundant routing capabilities without adding separate dedicated redundancy systems, thus improving continuous transmission reliability while minimizing increases in device complexity.
