Slider-Crank Antenna Mounting Bracket for Easy Downtilt Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antenna downtilt adjustment mechanisms require multiple components to be adjusted and tightened, leading to complex operations and higher costs.
Innovation Solution
A mounting bracket with a 'slider-crank' mechanism, featuring a first and second member with securing features that allow sliding and rotational adjustments, reducing the number of nuts needed for adjustment and simplifying the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional pivoting or sliding brackets are used to adjust antenna downtilt, then the antenna can be tilted to desired angles, but multiple nuts (16-28 nuts) need to be adjusted and tightened, making operation complicated
Solution Approach 1:
The patent combines multiple adjustment functions into a single integrated mechanism. The mounting bracket uses a unified pivoting assembly with slots and a single securing feature that simultaneously controls both the vertical position and tilt angle, eliminating the need to adjust multiple separate nuts and components.
Solution Approach 2:
The mounting bracket is designed as a multi-functional component that performs multiple operations through a single mechanism. The same pivoting assembly that adjusts vertical position also controls downtilt angle, making the device more versatile and reducing operational steps.
2Adaptability or versatility
If multiple components are used to achieve downtilt adjustment, then various angles can be achieved, but the operation costs increase due to complicated adjustment procedures
Solution Approach 1:
The patent merges multiple adjustment functions into a single integrated mechanism. The mounting bracket uses a unified pivoting assembly with slots and a single securing feature that simultaneously controls both the vertical position and tilt angle, eliminating the need to adjust multiple separate nuts and components.
Solution Approach 2:
The mounting bracket design allows for self-adjustment through its mechanical structure. The slots and pivoting mechanism enable the bracket to automatically maintain proper positioning through gravity and mechanical constraints, reducing the need for complex tightening and adjustment procedures.
3Strength
If traditional mounting brackets with multiple nuts are used, then structural integrity can be maintained, but the adjustment process becomes time-consuming
Solution Approach 1:
The patent combines multiple adjustment functions into a single integrated mechanism. The mounting bracket uses a unified pivoting assembly with slots and a single securing feature that simultaneously controls both the vertical position and tilt angle, eliminating the need to adjust multiple separate nuts and components.
Solution Approach 2:
The mounting bracket is pre-configured with slots and pivoting features that are designed to work together in a predetermined sequence. This preliminary design of the mechanical structure allows for quick adjustment without requiring multiple separate tightening operations.

AI summary
The present disclosure is directed to a mounting bracket adapted for adjusting the downtilt of an antenna. The mounting bracket includes a first member and a second member. The first member is coupled to the second member at one end via a first pair of securing features and is coupled to an antenna mounting bracket at an opposing end via a second pair of securing features. The first member is configured to rotate about the first and second pairs of securing features relative to the second member and antenna mounting bracket, respectively. The second member includes two slots on opposing sides that extend longitudinally along a length of the second member in a vertical direction, each of the first pair of securing features extends through and is configured to slide within a respective slot such that, when an antenna is secured to the antenna mounting bracket, sliding the first pair of securing features in a first direction increases an angle of downtilt for the antenna and sliding the first pair of securing features in a second direction decreases the angle of downtilt for the antenna. The second member is configured to be secured to a mounting structure. Other adjustable downtilt antenna mounting brackets and related assemblies are described herein.
