RRU Bracket Assembly with Adjustable Side Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and maintenance of remote radio units (RRUs) on telecommunication towers are labor-intensive and costly, requiring significant man-hours for secure mounting and proper orientation, while also facing challenges in efficiently connecting lateral spanning elements to tapered tower elements.
Innovation Solution
The RRU bracket assembly consists of a front and rear bracket plate with securing rods for a frictional fit on the tower frame, along with adjustable side walls and bolts for secure attachment and adjustable spacing, facilitating efficient and secure mounting of RRUs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting methods are used for RRUs, then secure attachment is achieved, but installation time and labor costs increase significantly
Solution Approach 1:
The mounting bracket is divided into multiple segments including a main bracket body, adjustable arms, and separate mounting plates. Each segment can be independently positioned and secured, allowing for modular assembly that reduces installation time while maintaining secure attachment through distributed connection points across the tower structure.
Solution Approach 2:
The bracket incorporates adjustable arms with movable joints that can be positioned at various angles and distances from the tower centerline. This dynamic adjustability allows the bracket to adapt to different RRU orientations and mounting locations without requiring custom-built brackets, significantly reducing installation time and labor costs.
2Ease of operation
If custom brackets are designed for each RRU orientation, then proper orientation is achieved, but device complexity and installation costs increase
Solution Approach 1:
The mounting bracket is designed as a universal structure that can accommodate multiple RRU orientations and positions through its adjustable arms and movable joints. A single bracket design can serve multiple functions by adjusting arm lengths, angles, and positions, eliminating the need for multiple custom bracket variants and simplifying inventory and installation procedures.
Solution Approach 2:
The bracket utilizes adjustable parameters including arm length, joint angles, and mounting plate positions that can be modified in the field to achieve proper RRU orientation. These parameter changes allow the same physical bracket to be configured for different orientations without requiring complex custom designs for each scenario.
3Stability of the object's composition
If lateral spanning elements are connected to tapered tower elements, then structural stability is improved, but connection difficulty and equipment requirements increase
Solution Approach 1:
The mounting bracket serves as an intermediary component between the tapered tower element and the RRU. It features a tapered interface that matches the tower's geometry, allowing stable connection without requiring complex lifting equipment. The bracket distributes connection forces across multiple attachment points, simplifying the connection process while maintaining structural stability.
