Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional electrical cabling is used for high-speed interconnections, then data transmission capability is achieved, but power consumption and cost increase significantly
Solution Approach 1:
The patent replaces traditional electrical signal transmission through copper cables with electromagnetic wave propagation through waveguides. This substitution transitions from electrical conduction to electromagnetic wave guidance, enabling high-speed data transmission with reduced power consumption and signal loss over long distances
2Length of stationary object
If optical cables are used for long-distance interconnections, then transmission distance and bandwidth are improved, but power consumption and system cost increase severely
Solution Approach 1:
The patent changes the transmission medium parameters from optical fiber to waveguide structures that support electromagnetic wave propagation. This parameter change enables long-distance transmission with lower power consumption by utilizing waveguide modes that experience less attenuation and require fewer active components for signal maintenance
3Productivity
If multiple waveguides are bundled together for high-speed data transmission, then bandwidth is improved, but crosstalk between waveguides increases
Solution Approach 1:
The patent introduces a dielectric material as an intermediary substance surrounding and separating individual waveguides within the bundle. This dielectric intermediary reduces electromagnetic coupling between adjacent waveguides, thereby minimizing crosstalk while allowing multiple waveguides to operate in close proximity for increased bandwidth
4Productivity
If hollow metal waveguides are used for electromagnetic wave propagation, then signal transmission is achieved, but mechanical stability and ease of connection deteriorate due to buckling and kinking
Solution Approach 1:
The patent employs composite waveguide structures consisting of dielectric materials with specific permittivity values, and in some embodiments, conductive outer layers combined with dielectric cores. This composite construction provides both the electromagnetic wave propagation characteristics needed for signal transmission and the mechanical strength required for stability and ease of handling
