Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a static DC power distribution system is used, then the system structure is simple, but the system lacks flexibility and cannot accommodate additional remote radio units or power sources
Solution Approach 1:
The power distribution system is segmented into modular components: multiple independent DC power sources, individual circuit breakers for each remote radio unit, and configurable jumper connections. This segmentation allows selective activation of power paths without affecting the entire system, enabling flexible reconfiguration while maintaining manageable complexity through standardization of modular units.
Solution Approach 2:
The system transitions from a static hardwired configuration to a dynamic reconfigurable architecture using jumper connections that can be selectively installed or removed. This allows the power distribution topology to adapt dynamically to changing requirements, such as adding new remote radio units or incorporating additional DC power sources, without requiring complete system redesign.
2Productivity
If additional remote radio units are added to meet increasing connectivity demand, then the system capacity increases, but the labor intensity and difficulty of reconfiguration increases
Solution Approach 1:
The system is pre-configured with multiple DC power source inputs and corresponding circuit breaker positions before deployment. Jumpers are pre-positioned in the distribution board to establish default power paths. This preliminary preparation enables rapid addition of new remote radio units by simply connecting jumpers without requiring complex rewiring or system reconfiguration, significantly reducing labor intensity.
Solution Approach 2:
The distribution board is designed with universal mounting positions and standardized jumper connections that can serve multiple functions: initial system setup, adding new remote radio units, and reconfiguring power paths. This multi-functionality allows the same infrastructure to accommodate varying numbers of remote radio units and different power distribution scenarios without requiring specialized components for each configuration.
3Power
If new DC power sources become available, then the power supply capacity increases, but the ability to integrate them into the existing system is limited
Solution Approach 1:
The system accepts multiple independent DC power sources as separate, modular inputs, each with its own dedicated circuit breaker positions in the distribution board. This segmentation allows new DC power sources to be independently integrated by connecting them to available power source inputs and configuring jumpers to the appropriate circuit breakers, without requiring modification to existing power paths or other power sources.
Solution Approach 2:
The distribution board acts as an intermediary between DC power sources and remote radio units, providing standardized connection points and jumper-based routing. This intermediary interface simplifies the integration of new DC power sources by offering pre-defined connection positions and configurable power paths, eliminating the need for custom wiring or complex integration procedures.
