Engineering Contradiction Analysis
1Productivity
If traditional computing cables are used without impedance-matched attenuators, then the cable structure is simple, but the signal loss varies with cable length leading to transmission inefficiency
Solution Approach 1:
The patent applies parameter changes by introducing an attenuator with specific impedance parameters that match the trace impedance. The attenuator's resistance and conductor impedance are carefully selected to create uniform loss characteristics, transforming the cable from having variable loss to having consistent loss per unit length regardless of total length.
Solution Approach 2:
The attenuator serves as an intermediary component between trace segments. It mediates the signal transmission by providing controlled impedance matching and uniform attenuation, ensuring consistent signal loss characteristics across different cable lengths without requiring complete redesign of the entire cable structure.
2Adaptability or versatility
If cable length is increased to extend connection distance, then connection versatility is improved, but signal loss becomes non-uniform degrading transmission quality
Solution Approach 1:
The patent changes the loss parameter characteristics by introducing the attenuator with matched impedance. This ensures that signal loss remains uniform and predictable regardless of cable length, maintaining transmission reliability whether the connection is short or extended.
Solution Approach 2:
The attenuator design provides universal applicability across different cable lengths. The same attenuator configuration works reliably whether the trace is short or extended, making the cable system versatile for various connection distances without compromising signal transmission consistency.
