Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional electrical cabling is used for high-speed interconnections, then data transmission can be achieved, but power consumption increases and cost becomes expensive
Solution Approach 1:
The patent replaces traditional electrical cable systems with a waveguide system that uses electromagnetic wave propagation. The waveguide comprises a conductive outer layer and dielectric core, guiding EM waves to transmit data signals between servers. This substitution eliminates the need for high-power electrical signaling while maintaining data transmission integrity, directly resolving the contradiction between power consumption and transmission efficiency.
2Productivity
If optical cables are used for long-distance interconnect, then bandwidth is improved, but power consumption and cost increase severely
Solution Approach 1:
The patent changes the fundamental transmission parameter from electrical signals or optical signals to electromagnetic waves in the waveguide. The waveguide structure with conductive outer layer and dielectric core enables efficient EM wave propagation that provides high bandwidth comparable to optical solutions while consuming significantly less power, as EM waves in waveguides experience lower attenuation and require less signal regeneration.
3Length of stationary object
If waveguide sections are joined to extend distance, then interconnect distance is improved, but connection complexity increases
Solution Approach 1:
The patent divides the waveguide into multiple modular sections that can be individually manufactured and then joined together using joining features. Each waveguide section contains standardized joining features at its ends, allowing multiple sections to be connected in sequence to achieve extended interconnect distances. This segmentation enables flexible deployment while maintaining manufacturing simplicity and connection reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Waveguides provide high bandwidth and reduce signal deterioration by using conductive and dielectric materials, enabling efficient data transmission with lower power consumption and cost compared to traditional electrical and optical solutions.
Implementation Method 1
A waveguide can be used to propagate electromagnetic waves including electromagnetic waves having a wavelength in millimeters (mm) or micrometers (μm) range
Implementation Method 2
Waveguides offer the bandwidth needed to meet the emerging requirements. However, a conventional waveguide can be prone to buckling or kinking when trying to connect the waveguide if the connection requires bending of the waveguide
