Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional electrical cabling is used for high-speed interconnections, then data transmission is achieved, but power consumption increases and cost increases
Solution Approach 1:
The patent replaces traditional electrical cable systems with a waveguide system that uses electromagnetic wave propagation. The waveguide comprises a dielectric core surrounded by a conductive layer, creating a transmission medium that guides electromagnetic waves between electronic devices. This substitution eliminates the need for high-power electrical signaling while maintaining data transmission capability, directly resolving the contradiction between productivity and power consumption.
2Productivity
If traditional electrical cabling is used for high-speed interconnections, then data transmission is achieved, but system cost increases
Solution Approach 1:
The patent changes the fundamental transmission parameter from electrical signaling through cables to electromagnetic wave propagation through a waveguide structure. By modifying the transmission medium parameters (dielectric core with conductive layer), the system achieves high-speed data transmission with reduced cost compared to traditional electrical cabling systems requiring equalization and advanced modulation techniques.
3Productivity
If optical cables are used for long-distance interconnections, then bandwidth is improved, but power consumption increases and cost increases
Solution Approach 1:
The patent substitutes optical fiber transmission with a waveguide-based electromagnetic wave transmission system. The waveguide structure, consisting of a dielectric core and conductive layer, enables high-bandwidth communication without the severe power penalties associated with optical transceivers. This substitution maintains bandwidth performance while dramatically reducing power consumption.
4Productivity
If electrical cable quality is improved to extend reach or bandwidth, then data transmission performance is improved, but cost increases and power consumption increases
Solution Approach 1:
The patent replaces the approach of improving electrical cable quality (which increases cost) with a fundamentally different waveguide transmission system. The waveguide structure inherently supports high-frequency signals without requiring expensive cable materials or advanced signal processing, achieving improved data transmission performance at lower cost.
