Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional single RRU mounting is used on antenna towers, then each mounting location supports only one remote radio unit, but this results in inefficient space utilization and requires more mounting locations for multiple RRUs
Solution Approach 1:
The mounting bracket is divided into multiple hanger plates (first hanger plate, second hanger plate, third hanger plate) that can independently support different RRUs. Each hanger plate can be positioned at different locations along the main support member, allowing flexible accommodation of multiple RRUs at a single mounting location while maintaining structural organization and reducing overall complexity.
Solution Approach 2:
The mounting bracket assembly is designed as a universal structure that can accommodate multiple types and sizes of remote radio units simultaneously. The adjustable hanger plates and multiple mounting locations enable a single bracket assembly to serve multiple functions - supporting different RRU configurations, accommodating future expansions, and adapting to various tower types without requiring custom mounting solutions.
2Area of stationary object
If multiple RRUs are mounted on separate mounting locations, then each RRU has dedicated mounting space, but this increases the number of mounting locations needed and reduces space utilization on existing towers
Solution Approach 1:
Instead of distributing multiple RRUs across different vertical locations on the tower, the invention utilizes the horizontal dimension by incorporating multiple hanger plates that can be positioned at different lateral positions along the main support member. This dimensional approach allows multiple RRUs to be mounted at essentially the same vertical location, maximizing space utilization while maintaining installation simplicity through a standardized bracket assembly.
3Adaptability or versatility
If custom mounting solutions are designed for different RRU configurations, then each configuration has optimized mounting, but this increases device complexity and manufacturing costs
Solution Approach 1:
The mounting bracket incorporates adjustable and reconfigurable elements, including hanger plates that can be positioned at different locations along the main support member and secured at various heights. This dynamic design allows the same bracket assembly to adapt to different RRU configurations without requiring custom-manufactured brackets for each scenario, thereby maintaining manufacturing simplicity while achieving high configuration flexibility.
Solution Approach 2:
The invention utilizes variable parameters such as the position of hanger plates, the number of active mounting points, and the arrangement of clamp assemblies to accommodate different RRU configurations. By changing these parameters rather than redesigning the entire mounting structure, the system achieves configuration flexibility while keeping manufacturing processes standardized and simple.
