Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple connectors are mounted using prior art mounting structures, then the antenna can perform RF testing, but the protection performance and anti-electromagnetic interference performance cannot be ensured after the extrusion frame is mounted
Solution Approach 1:
The mounting structure is divided into separate functional components: a mounting plate for mechanical attachment, a protective pad for sealing and protection, and a supporting component for structural support. This segmentation allows each component to be optimized for its specific function while working together to achieve both mounting capability and protection performance.
Solution Approach 2:
The protective pad acts as an intermediary component between the mounting plate and the extrusion frame. It provides the necessary sealing and protection while allowing the mounting structure to maintain both mechanical stability and electromagnetic shielding effectiveness.
2Productivity
If prior art mounting structures are used to mount multiple connectors, then connectors can be connected to the inner core, but the mounting work becomes relatively complex
Solution Approach 1:
By dividing the mounting structure into modular components (mounting plate, protective pad, supporting component), the assembly process becomes more systematic and easier to execute, reducing the complexity of mounting multiple connectors simultaneously.
Solution Approach 2:
The mounting plate is designed with multiple mounting holes that can accommodate multiple connectors, making the structure universal and multi-functional. This allows several connectors to be mounted using the same basic structure, simplifying the overall mounting process.
3Manufacturing precision
If the first flange and second flange are at the same height, then the structure appears symmetric, but manufacturing tolerance may cause the second flange to be higher than the first flange, preventing good surface contact
Solution Approach 1:
The first flange is designed to be higher than the second flange, creating an asymmetric structure. This intentional asymmetry ensures that the first flange makes contact with the extrusion frame first, compensating for manufacturing tolerances and ensuring reliable surface contact and sealing.
Solution Approach 2:
The protective pad is positioned to compensate for potential height variations between flanges. It provides a cushioning effect that ensures proper sealing and contact even when manufacturing tolerances cause deviations from the ideal geometry.

AI summary
The present disclosure discloses a mounting structure, an antenna device and a method for assembling the antenna device. The mounting structure is used for mounting a connector to a first fixing part and a second fixing part, and comprises: a main body portion which defines a hollow cavity for receiving the connector, a first flange arranged on an upper surface of the main body portion around the hollow cavity and a second flange arranged on the upper surface of the main body portion around the first flange and spaced apart from the first flange; a protective pad received in a protective pad receiving portion defined between the first flange and the second flange; a supporting component to be fixed to the second fixing part, the main body portion being fitted within the supporting component; and at least one fastener used for fastening the mounting structure to the first fixing part, so that the first flange comes into direct contact with the lower surface of the first fixing part.
