Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing bonding mechanism between male and female SMA antenna connectors requires a wrench for assembly and disassembly, making it inconvenient, and the connectors may become loose due to gravity, leading to tilting issues.
Innovation Solution
A quick-release module design featuring two double connector assemblies with inclined outer walls and elastic arms that engage and disengage without tools, allowing for efficient assembly and disassembly while enhancing structural strength by integrating the bottom plate with the connectors, reducing the likelihood of tilting due to gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wrench is used to screw the male and female SMA antenna connectors together, then the bonding between connectors is secure, but the assembly and disassembly process becomes inconvenient and time-consuming
Solution Approach 1:
The patent replaces the traditional screw-thread mechanical bonding system with a snap-fit engagement system. The male connector features an inclined outer wall that guides the female connector's engaging portion into place, eliminating the need for rotational screwing motions and wrench tools while maintaining secure connection through elastic deformation and geometric interlocking.
Solution Approach 2:
The connector design enables self-aligning and self-locking functionality. The inclined outer wall automatically guides the engaging portion into the correct position during insertion, and the elastic arm structure provides automatic locking without requiring external tools or manual intervention, allowing the connection to establish itself through simple insertion motions.
2Stability of the object's composition
If traditional screw bonding is used for antenna connectors, then the connection is stable, but the connectors may tilt toward the direction of gravity and become loose after long-term bonding
Solution Approach 1:
The patent introduces dynamic elastic elements (elastic arms and elastic deformation zones) that allow the connector components to flex and adapt to gravitational forces and mechanical stresses. This dynamic structure enables the connectors to maintain their bonding relationship while accommodating tilting forces through controlled elastic deformation, preventing permanent loosening that occurs with rigid screw connections.
Solution Approach 2:
The patent combines multiple functional elements into an integrated structure: the inclined outer wall serves both as a guiding surface and a locking surface, while the elastic arm simultaneously provides both structural support and locking force. This merging of functions creates a more robust connection that resists tilting forces more effectively than separate screw and support structures.
3Productivity
If a quick-release mechanism with elastic arms is used, then assembly and disassembly become tool-free and efficient, but the structural complexity increases
Solution Approach 1:
The patent divides the connector into distinct functional segments: the male connector body with inclined outer wall, the female connector with engaging portion, and the elastic arm as a separate functional element. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity, as each segment performs a single well-defined role in the quick-release mechanism.

Function Achieved in This Case
Enables quick and efficient assembly and disassembly of antenna connectors without tools, while providing robust structural strength to prevent tilting caused by gravity, thus improving the overall efficiency and stability of the connector system.
Implementation Method 1
Each of the second connectors includes a first elastic arm and a second engaging portion located at an end of the first elastic arm. When the second double connector assembly is plugged into the first double connector assembly, the second engaging portion moves along the corresponding inclined outer wall and engages with the first engaging portion.
