Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hybrid fiber optic and copper cable networks are used for content delivery, then network coverage and existing infrastructure utilization are improved, but bandwidth capacity and performance are limited
Solution Approach 1:
The patent segments the hybrid network into distinct functional portions: optical fiber segments for high-bandwidth backbone transmission and copper cable segments for existing subscriber connections. This allows the network to leverage the high capacity of fiber optics while maintaining compatibility with existing copper infrastructure, thereby increasing overall bandwidth capacity without sacrificing network coverage.
Solution Approach 2:
The patent merges fiber optic cable and copper cable into a single hybrid assembly, combining the high bandwidth capacity of fiber optics with the extensive reach and existing infrastructure of copper cables. This integration allows the network to achieve both wide coverage and high performance by utilizing the complementary strengths of both cable types within the same physical structure.
2Quantity of substance
If new communication networks with optical fibers routed to subscribers are installed, then bandwidth capacity is dramatically increased, but deployment complexity and cost increase
Solution Approach 1:
The patent combines fiber optic cables and copper cables into a single pre-assembled hybrid cable unit, eliminating the need for separate deployment of fiber and copper infrastructure. This merged assembly reduces deployment complexity by allowing installers to deploy a single cable type that delivers both optical and electrical signals, while still achieving the high bandwidth capacity of fiber-to-the-home networks.
Solution Approach 2:
The hybrid cable assembly serves multiple functions simultaneously: it provides high-bandwidth optical transmission for new services, maintains backward compatibility with existing copper-based subscriber equipment, and enables both new fiber-optic nodes and legacy copper network integration. This multi-functionality reduces deployment complexity by accommodating multiple network requirements within a single infrastructure solution.
3Quantity of substance
If fiber optic assemblies are installed to add nodes to existing networks, then bandwidth to subscribers is increased, but installation time and disruption to existing service may occur
Solution Approach 1:
The patent incorporates pre-terminated optical connectors and pre-assembled fiber-copper interfaces within the hybrid cable assembly during manufacturing. This preliminary preparation eliminates time-consuming field termination and splicing operations, allowing installers to simply connect pre-configured assemblies to existing network nodes, thereby reducing installation time and minimizing service disruption while delivering increased bandwidth capacity.
