Antenna Frame Assembly for Reliable Cable Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of antennas in network communication devices is challenging due to the need for long signal cables and the difficulty in adjusting the antenna's position and angle, leading to increased production time and cost.
Innovation Solution
The use of an antenna frame that is assembled directly on the circuit board, with the antenna engaged in a slot on the frame, provides a secure and adjustable mounting system that simplifies assembly and reduces the risk of signal cable disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna is fixed on the housing by adhesive and connected through a long signal cable, then the antenna can be mounted on the housing, but the assembly becomes complex and the signal cable falls off easily when pulled
Solution Approach 1:
The patent merges the antenna mounting function and the signal cable connection function into a single integrated antenna frame structure. The antenna frame is assembled directly on the circuit board and provides both mechanical support for the antenna and integrated signal cable routing, eliminating the need for separate mounting brackets and cable management components. This integration reduces assembly complexity and improves connection reliability.
Solution Approach 2:
The antenna frame serves as an intermediary structure between the circuit board and the antenna. It provides a stable mounting platform that is directly assembled on the circuit board, and simultaneously integrates the signal cable connection points. This intermediary structure eliminates the need for long signal cables and separate mounting mechanisms, reducing both complexity and improving reliability.
2Reliability
If the antenna is assembled to the housing and connected to the circuit board, then the antenna can be installed, but a test needs to be performed on the whole assembly and adjustment takes a lot of time when the test result is not good
Solution Approach 1:
The patent segments the antenna assembly into modular components: the antenna frame (assembled on the circuit board), the antenna element (engaged in the slot), and the signal cable (integrated into the frame). This segmentation allows for independent assembly and testing of each module, enabling quick identification and adjustment of problematic components without retesting the entire assembly, thus reducing adjustment time while maintaining test reliability.
Solution Approach 2:
The antenna frame incorporates a slot that allows the antenna to be engaged and disengaged easily, providing dynamic adjustability during the testing phase. The slot design enables quick repositioning and angle adjustment of the antenna element without requiring complex fastening or disassembly operations, significantly reducing the time needed for adjustments when test results are not satisfactory.
3Ease of operation
If a long signal cable is used to connect the antenna to the circuit board, then the antenna can be connected, but the signal cable falls off easily when being pulled
Solution Approach 1:
The patent extracts the signal cable connection points from the traditional housing-mounted configuration and relocates them directly to the circuit board through the antenna frame. This extraction eliminates the need for long signal cables that are prone to falling off, as the connections are now made at the source (circuit board) rather than through extended cable runs, improving reliability while maintaining ease of connection through the integrated frame structure.
