Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductors are arranged in a wavelike manner to achieve identical geometric lengths, then phase differences are avoided, but the characteristic impedance changes along the conductors leading to limited bandwidth and bit rate
Solution Approach 1:
The patent applies curvature to the conductor paths in a controlled manner. Instead of wavelike arrangements that change distance between conductors, the invention uses curved sections where conductors follow arcs of different radii, maintaining constant spacing and characteristic impedance while achieving identical geometric lengths through precise geometric design
Solution Approach 2:
The invention changes the geometric parameters of the conductor arrangement by using curved paths with specific radii and angles. The conductors are arranged in curved sections with predetermined angles and radii that compensate for length differences, maintaining constant characteristic impedance while achieving equal electrical lengths for differential signaling
2Productivity
If conductors are arranged directly on the shortest paths between connectors, then the characteristic impedance remains constant, but the conductors have different geometric lengths causing phase differences in high-frequency signals
Solution Approach 1:
The patent introduces curved sections for the conductors that allow adjustment of geometric lengths while maintaining constant spacing. The curved paths enable the conductors to follow non-linear trajectories with predetermined angles and radii, compensating for length differences and achieving equal electrical lengths without compromising signal synchronization
Solution Approach 2:
The invention employs asymmetric conductor arrangements where individual conductors follow different curved paths with different radii and angles. This asymmetric design allows each conductor to be optimized for its specific route while maintaining constant spacing and characteristic impedance, achieving both equal lengths and constant impedance simultaneously
3Length of moving object
If the distance between adjacent conductors changes in a wavelike manner, then identical geometric lengths are achieved, but the characteristic impedance is not maintained leading to signal transmission limitations
Solution Approach 1:
The patent uses curved conductor sections where the distance between adjacent conductors remains constant throughout the curved path. The conductors follow arcs with different radii but maintain fixed spacing, ensuring that the characteristic impedance remains constant while achieving identical geometric lengths through the geometric relationship between the curved paths
