Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a coil-shape inductor is used to raise impedance on the signal path, then sufficient voltage swing is achieved, but the inductor occupies a large area and introduces magnetic coupling that degrades system performance
Solution Approach 1:
The patent combines the transmission wire and resonance wire into a unified structure where the resonance wire is routed along the transmission wire. This merging eliminates the need for separate coil-shape inductors, reducing area occupation while maintaining the voltage swing enhancement through resonant effect at the oscillation frequency.
Solution Approach 2:
The patent replaces the traditional mechanical coil-shape inductor structure with an integrated resonance wire configuration. This substitution eliminates the magnetic coupling issues inherent in coil structures while achieving the same electrical function of raising impedance and enhancing voltage swing through distributed resonant elements.
2Strength
If a coil-shape inductor is used to raise impedance on the signal path, then sufficient voltage swing is achieved, but magnetic coupling is introduced that greatly impacts operations of nearby blocks
Solution Approach 1:
The patent replaces the coil-shape inductor with an integrated resonance wire structure routed along the transmission wire. This substitution eliminates the concentrated magnetic field of coil inductors, preventing magnetic coupling with nearby blocks while maintaining voltage swing enhancement through distributed resonant effect.
Solution Approach 2:
The patent segments the inductor function into distributed resonant elements along the transmission wire rather than using a single concentrated coil. This segmentation distributes the magnetic field, preventing strong localized magnetic coupling with nearby circuit blocks while achieving the same impedance raising effect.
3Speed
If power consuming driving circuits are used to drive high frequency signals over wide area, then signal transmission is achieved, but power consumption increases
Solution Approach 1:
The patent utilizes resonant vibration at the oscillation frequency by routing the resonance wire along the transmission wire. This resonant effect naturally amplifies the signal voltage swing, reducing the power required from driving circuits to maintain sufficient voltage levels over wide area mm-Wave signal transmission.
Solution Approach 2:
The patent changes the electrical parameters of the signal path by introducing resonant effect at the oscillation frequency. This parameter change enhances voltage swing and reduces the power consumption of driving circuits by utilizing the resonant amplification effect rather than relying solely on increased driving power.
