Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting brackets for antenna alignment devices are inadequate for soft side antennas, as they create high-pressure regions that can deform or damage the antenna and are prone to slippage, especially in wet or mossy conditions.
Innovation Solution
A mounting bracket with an abutment pad composed of a soft material for traction and a hard material for structural integrity, providing a larger surface area to distribute clamping force and prevent slippage, featuring a two-piece design with adjustable fastening mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional rigid bracket components are used to attach to soft side antennas, then structural integrity of the bracket is maintained, but high-pressure regions are created that deform or damage the antenna surface
Solution Approach 1:
The bracket component is divided into two distinct pieces: a rigid piece providing structural integrity and a soft piece providing gentle contact with the antenna surface. This segmentation allows each piece to fulfill its specific function without compromising the other, resolving the contradiction between structural strength and surface protection.
Solution Approach 2:
The bracket uses a composite structure combining rigid material (for strength) and soft material (for surface compatibility). This composite approach allows the bracket to simultaneously maintain its structural integrity while distributing clamping force over a larger effective area to prevent antenna deformation.
2Reliability
If small surface area bracket components are used, then clamping force is concentrated for secure attachment, but high-pressure regions are created on the antenna surface
Solution Approach 1:
By separating the bracket into rigid and soft pieces, the functional requirements of secure attachment and pressure distribution are assigned to different components. The soft piece specifically addresses pressure distribution while the rigid piece provides attachment security.
Solution Approach 2:
The soft piece changes the physical parameters of the contact surface (increasing compliance and effective contact area), which transforms the pressure distribution characteristics to reduce peak pressures on the antenna surface while maintaining attachment reliability.
3Ease of manufacture
If conventional rigid bracket components are used, then manufacturing simplicity is maintained, but slippage occurs on wet or mossy antenna surfaces
Solution Approach 1:
The segmentation of the bracket into rigid and soft pieces allows the soft piece to specifically address grip stability on slippery surfaces. The soft material's inherent friction characteristics provide reliable grip without complicating the overall manufacturing process, as the soft piece can be attached to the simple rigid structure.
4Object-affected harmful factors
If soft material is used for the entire bracket component, then antenna surface protection is improved, but structural integrity and stability are compromised
Solution Approach 1:
The bracket is segmented into two functional pieces: the soft piece provides surface protection and the rigid piece provides structural stability. This clear division of functions allows both requirements to be satisfied simultaneously without compromise.
Solution Approach 2:
The composite structure combines soft and rigid materials in a single bracket assembly, allowing the soft material to protect the antenna surface while the rigid material provides the necessary structural stability for maintaining alignment during the antenna alignment process.

AI summary
In an example mounting bracket for an antenna alignment device, a bracket component that abuts an antenna is provided. The bracket component has a relatively large surface area for a wider distribution of the applied clamping force, thereby minimizing high-pressure regions. Generally, the bracket component is made of a first piece and a second piece. The first piece is made of soft material such as e.g., rubber that abuts and grips an exterior surface of the antenna, thereby minimizing the slippage problem when the antenna surface is wet and or mossy. The second piece is made of rigid material such as metal or a metal alloy (e.g., an aluminum alloy) to maintain the structural integrity of the bracket component.
