Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If optical components are used in optical networking systems, then high bandwidth transmission is achieved, but power dissipation increases and thermal management problems occur
Solution Approach 1:
The patent replaces optical components (which generate heat through photon emission) with electromagnetic waveguides that transmit signals through electromagnetic field propagation. This substitution eliminates the need for optical amplifiers, lasers, and LEDs, thereby reducing power dissipation while maintaining high bandwidth transmission capabilities through the waveguide structure.
Solution Approach 2:
The patent changes the operating parameters from optical frequency (requiring photon generation) to electromagnetic frequency ranges (microwave, millimeter-wave, terahertz) that can be transmitted through waveguides. This parameter change allows signal transmission without the heat-generating processes inherent in optical component operation, thus reducing power dissipation while preserving transmission performance.
2Productivity
If optical components are used to achieve high bandwidth, then data transmission capacity increases, but thermal control requirements become more stringent
Solution Approach 1:
The patent substitutes optical components with electromagnetic waveguides, eliminating the thermal sensitivity inherent in optical devices. The waveguide structure operates in electromagnetic frequency ranges that are less sensitive to temperature fluctuations, thereby maintaining data transmission capacity without stringent thermal control requirements.
3Productivity
If optical components are used for high bandwidth transmission, then signal capacity increases, but mechanical alignment precision requirements increase
Solution Approach 1:
The patent replaces optical transmission components with electromagnetic waveguides, substituting a system requiring precise mechanical alignment (optical components) with one that is more tolerant of manufacturing variations. The waveguide structure maintains high signal transmission capacity while reducing sensitivity to mechanical alignment precision through its electromagnetic field-based operation.
4Productivity
If fiber-optic cable termination is used for signal transmission, then optical communication is achieved, but electromagnetic wave reflections cause signal interference
Solution Approach 1:
The patent substitutes optical fiber termination with electromagnetic waveguide termination, eliminating the reflection problems inherent in optical interfaces. The waveguide structure provides continuous electromagnetic field propagation without the discrete termination points that cause reflections in optical systems, thereby maintaining communication performance while eliminating signal interference.
Solution Approach 2:
The patent addresses reflection interference by designing waveguide terminations that transform potential harmful reflections into beneficial signal absorption or transmission. The electromagnetic waveguide structure allows for controlled impedance matching and termination designs that convert reflected energy into useful signal continuation or controlled dissipation, eliminating the harmful interference effect.
