Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional parallel buses are used for information transmission, then the system structure is simple, but the transmission rate is limited and the system is highly sensitive to interference
Solution Approach 1:
The invention segments the transmission medium into multiple independent differential pairs within a multi-conductor system, allowing simultaneous transmission of multiple symbols. Each differential pair operates independently, enabling parallel transmission while maintaining signal integrity through differential signaling principles.
Solution Approach 2:
The invention transitions from traditional single-bit per line transmission to multi-level signaling where multiple symbols are transmitted simultaneously over multiple conductor pairs. This dimensional expansion in signal space enables higher transmission rates without proportionally increasing physical complexity.
2Reliability
If differential line systems are used for high-speed transmission, then signal integrity is improved, but information transmission efficiency and power consumption worsen
Solution Approach 1:
The invention merges multiple differential signaling pairs into a unified multi-conductor system where symbols are transmitted in parallel. By combining the reliability of differential signaling with multi-symbol transmission, the system achieves both high signal integrity and improved transmission efficiency.
Solution Approach 2:
The invention changes the signaling parameters by transmitting multiple symbols simultaneously across multiple conductor pairs rather than single bits sequentially. This parameter transformation increases information density per transmission cycle while maintaining the robust differential signaling characteristics.
3Productivity
If more conductor pairs are used to increase transmission rate, then the signaling rate improves, but power consumption and cost increase
Solution Approach 1:
The invention maintains continuous transmission of multiple symbols in parallel across the multi-conductor system, maximizing the utilization of available conductors. This continuous multi-symbol transmission achieves high signaling rates without requiring excessive power per symbol transmitted.
Solution Approach 2:
The multi-conductor system is designed to handle multiple symbols simultaneously, making each conductor pair contribute to the overall transmission capacity. This multi-functional approach allows the system to achieve high signaling rates efficiently by distributing the transmission load across multiple conductors rather than over-provisioning a single high-speed path.
