Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RJ connector coupling technologies cannot efficiently couple devices requiring both power and data connections using twisted pair cables, as they require separate power and data conductors, leading to limitations in power transmission and incompatibility with conventional RJ connector couplings.
Innovation Solution
A plug-in coupling device with separate data and power coupling devices, where data and power contact elements are electrically isolated and arranged in a crossed configuration on printed circuit boards, allowing for efficient data and power transmission between RJ connectors, including compatibility with Power-over-Ethernet protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If separate power and data conductors are used in twisted pair cables, then power transmission capability is improved, but compatibility with conventional RJ connector couplings deteriorates
Solution Approach 1:
The coupling device is segmented into separate power coupling components and data coupling components, each handling their respective functions independently. This allows the device to support both separate power/data conductor configurations and conventional PoE configurations through different coupling paths.
Solution Approach 2:
The coupling device is designed with universal functionality to accommodate multiple connector types and configurations. It can couple connectors with separate power and data conductors as well as conventional PoE connectors using twisted pair cables, making it adaptable to different power transmission requirements.
2Device complexity
If data and power conductors are combined in the same RJ connector, then device complexity is reduced, but electrical interference between data and power signals increases
Solution Approach 1:
The coupling device segments power signal paths and data signal paths into separate electrical domains. By providing dedicated power coupling components and data coupling components with separate contact elements and conductive paths, the device eliminates electrical interference while maintaining combined power and data transmission capability.
Solution Approach 2:
The coupling device acts as an intermediary between the first and second RJ connectors, providing isolation and separation between power and data signal paths. The separate power and data coupling components serve as mediators that prevent direct electrical interference while enabling both functions to coexist in the same connector system.
