Engineering Contradiction Analysis
1Reliability
If multiple separate feeder cables are routed up the tower to each RRH, then each RRH can receive dedicated signal and power, but cable routing complexity increases significantly
Solution Approach 1:
The system segments cable management into modular connection interfaces, each handling specific cable types (signal, power, or both). Each RRH receives a dedicated connection interface module that can be independently managed, allowing separate feeder cables to be organized into discrete, manageable units rather than a complex tangled system.
Solution Approach 2:
Connection interface modules act as intermediary devices between the tower infrastructure and RRH units. These modules provide standardized connection points and organization structures that mediate the routing of multiple separate feeder cables, transforming the complex cable routing problem into a structured interface management task.
2Device complexity
If a common hybrid cable is routed up the tower and separated near the top, then cable routing is simplified, but connection complexity and installation difficulty increase
Solution Approach 1:
The system performs preliminary action by pre-organizing cable separation points and connection interfaces at the top of the tower. Connection interface modules are pre-configured with alignment structures and mounting mechanisms that guide the separation and connection processes, reducing installation difficulty despite the complexity of handling multiple cable types.
Solution Approach 2:
The system extracts the separation and connection functions into dedicated connection interface modules. These modules take out the complex task of separating hybrid cables into individual signal and power cables and performing the connections, providing a structured framework that simplifies the overall installation process.
3Adaptability or versatility
If connection interfaces are designed to accommodate future capacity expansion, then network scalability is improved, but initial device complexity increases
Solution Approach 1:
Connection interface modules are designed with universal mounting structures and standardized connection points that can accommodate different cable types and configurations. The base bracket and connection carrier designs provide multi-functional capabilities that support current RRH connections while enabling future expansions to additional RRHs or different cable types without requiring completely new interface designs.

AI summary
A connection interface includes a base bracket and a cable connection carrier (e.g., module, panel, etc.). The cable connection carrier has a front wall to which one or more cable connection components (e.g., optical components, electrical components, and/or hybrid components) are mounted. The cable connection carrier may angle the cable connection components relative to an open front of the base bracket. Some cable connection carriers may be snap-fit to the base bracket for easy installation. Other cable connection carriers are movable (e.g., pivotal) relative to the base bracket.
