Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna connectors generate insufficient torsion for heavy antennas, causing them to fall and lose optimal signal transmission angles due to gravity.
Innovation Solution
An antenna connector design featuring a casing with perforations and flanges, combined with multiple rubber rings and grooves, applies multi-directional compression forces to provide a larger torque, ensuring the antenna maintains desired angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a single axial compression force is applied to the rubber ring, then the antenna connector achieves simple structure and ease of manufacture, but the generated torsion is insufficient for heavy antennas, causing them to fall and cannot maintain the desired angle
Solution Approach 1:
The patent divides the single rubber ring into two separate rubber rings (first rubber ring and second rubber ring), each receiving compression forces from different directions. The first rubber ring receives axial compression from the shaft, while the second rubber ring receives radial compression from the casing, thereby generating sufficient total torsion to support heavy antennas without requiring complex additional structures
Solution Approach 2:
The patent introduces radial compression force as a new dimension alongside the existing axial compression force. The second rubber ring is compressed radially by the casing, adding a perpendicular dimension of force application. This multi-dimensional approach to force application generates sufficient torsion to prevent heavy antennas from falling while maintaining structural simplicity
2Reliability
If the antenna is made heavy for better signal transmission, then the signal transmission quality is improved, but the antenna cannot be maintained at the optimal angle due to insufficient torsion from single axial compression
Solution Approach 1:
The patent segments the torsion generation into two independent rubber ring systems: the first rubber ring handles axial compression for basic torsion, while the second rubber ring handles radial compression for additional torsion support. This segmentation allows the connector to support heavier antennas that provide better signal transmission while maintaining the antenna at the desired angle through combined torsion from both rings
Solution Approach 2:
The patent changes the compression force parameters by introducing both axial compression (from the shaft on the first rubber ring) and radial compression (from the casing on the second rubber ring). This parameter change enables the system to generate sufficient total torsion to maintain angle stability for heavy antennas that require better signal transmission
3Stability of the object's composition
If multiple rubber rings and grooves are added to provide larger torque, then the antenna can be maintained at any desired angle, but the device complexity increases
Solution Approach 1:
The patent makes the shaft and casing multi-functional: the shaft not only transmits rotation but also applies axial compression to the first rubber ring; the casing not only protects the internal components but also applies radial compression to the second rubber ring. This multi-functionality allows angle maintenance for heavy antennas without adding separate complex structures
Solution Approach 2:
The patent employs a nested structure where the first rubber ring is positioned within the shaft's first groove, and the second rubber ring is positioned within the shaft's second groove, with both rings nested within the casing. This nested arrangement accommodates multiple compression elements in a compact configuration, maintaining angle stability without excessive device complexity

AI summary
An antenna connector has a casing, a shaft, a first rubber ring, and a second rubber ring. An antenna is mounted on the shaft. The shaft can rotate relative to the casing. The casing has a first flange. The shaft has a first groove, a second flange, and a second groove. The second groove is formed on the surface of the second flange. The first rubber ring fits the first groove, the surface of the perforation, the first contact surface and the second contact surface, exerted with two axial compression forces and one radial compression force concurrently. The second rubber ring fits the second groove and the casing and so is exerted with one radial compression force. Therefore, as the antenna is rotated, the first rubber ring and the second rubber ring provide a larger torque.
