Single-Pair Ethernet Daisy Chaining Without Terminating Resistors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing single-pair Ethernet systems are limited by the need for terminating resistors, which prevent power and data transmission, and require stub cables to be under 30 cm in length, restricting network flexibility and expansion.
Innovation Solution
A single-pair Ethernet device with conductor paths that connect input and output contacts, allowing flexible configuration and simultaneous data and power transmission without terminating resistors, enabling easy addition or removal of devices via daisy chaining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional Ethernet infrastructure (cables, switches, routers) is installed in buildings, then network connectivity and bandwidth are provided, but installation complexity, cost, and time consumption increase
Solution Approach 1:
The patent combines multiple Ethernet communication pairs into a single physical cable pair, enabling multiple network connections to share one physical medium. This merging approach reduces the number of cables, switches, and installation steps while maintaining network connectivity functionality.
Solution Approach 2:
The single-pair Ethernet cable is designed to support multiple Ethernet communication functions simultaneously, allowing one cable to replace what traditionally required multiple separate cables and network infrastructure components.
2Adaptability or versatility
If traditional Ethernet cables and infrastructure are installed, then network bandwidth is provided, but installation cost and time increase
Solution Approach 1:
By merging multiple Ethernet communication channels into a single cable pair, the installation process is simplified and accelerated. Installers need to deploy fewer physical cables and configure fewer network devices, directly reducing installation time while maintaining bandwidth capacity.
3Adaptability or versatility
If multiple Ethernet cables are installed for different communication pairs, then network functionality is achieved, but cable management complexity and installation cost increase
Solution Approach 1:
The invention merges multiple Ethernet communication pairs into a single physical cable, dramatically reducing the quantity of cables required. This approach maintains full network functionality while eliminating the need to install and manage multiple separate cable bundles.
4Adaptability or versatility
If traditional Ethernet infrastructure is deployed, then communication capability is provided, but environmental impact from material usage increases
Solution Approach 1:
By combining multiple communication channels into a single cable pair, the patent reduces the total amount of physical material required for network deployment. This approach maintains communication capability while minimizing material consumption and associated environmental impact.
