Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electronic signal lines are used for switching, then the switch can be constructed with existing technology, but the bandwidth is limited and power consumption increases with more channels
Solution Approach 1:
The patent replaces electronic signal transmission with optical signal transmission using waveguides. Light signals are used to carry data between input and output ports, substituting the electronic mechanical system with an optical system that provides higher bandwidth and lower power consumption.
Solution Approach 2:
The patent changes the fundamental parameter of signal transmission from electrical to optical domain. By using different wavelengths of light for different data channels and employing optical switching mechanisms, the system achieves higher bandwidth capacity without proportionally increasing power consumption.
2Adaptability or versatility
If the number of input/output channels is increased, then the switch capacity increases, but the power consumption and signal integrity issues worsen
Solution Approach 1:
The patent creates a universal switching platform where a single optical switch fabric can handle multiple wavelengths and data rates simultaneously. The same physical infrastructure supports various channel configurations, making the system adaptable to different network requirements without proportionally increasing power consumption for each additional channel.
3Adaptability or versatility
If long signal lines are used to connect any input to any output, then the switch connectivity is complete, but power consumption in repeaters increases significantly
Solution Approach 1:
The patent replaces electronic signal transmission with optical signal transmission through waveguides. Optical signals experience much lower attenuation over long distances, eliminating or reducing the need for electronic repeaters and their associated power consumption while maintaining complete connectivity between any input and output ports.
4Ease of manufacture
If electronic switching is used, then the switch can be fabricated with current technology, but it cannot accommodate future higher bandwidth demands
Solution Approach 1:
The patent changes the fundamental operating parameter from electronic to optical domain. By using light wavelengths and optical switching mechanisms, the system achieves bandwidth capacities that exceed current electronic switching limits while still being fabricable with integrated photonic technologies that are becoming increasingly mature.
