Antenna Module Mounting Structure for Stable In-Housing Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in securely fixing antenna modules inside the device, which can lead to instability and reduced communication performance due to the lack of effective anchoring mechanisms.
Innovation Solution
An electronic device design that incorporates a non-conductive cap with protruding portions passing through a recessed area of the side wall, coupled with a bracket and coupling holes, securely mounts the antenna module, enhancing its fixation and adhesion area within the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna module is mounted inside the housing without a secure fixing mechanism, then the device structure remains simple, but the antenna module becomes unstable and communication performance deteriorates
Solution Approach 1:
The fixing mechanism is segmented into multiple functional components: a bracket with mounting holes for positioning, a non-conductive cap with protruding portions for insertion, and coupling holes for securing. This segmentation allows each component to perform its specific function effectively while maintaining overall system reliability.
Solution Approach 2:
The non-conductive cap is nested within the recess of the side wall, and the bracket is positioned within the housing such that the protruding portions of the cap pass through the bracket. This nested arrangement allows compact integration of multiple fixing elements without increasing overall device volume.
2Reliability
If the antenna module is firmly secured with multiple coupling components, then communication performance improves, but the manufacturing process becomes more complex
Solution Approach 1:
The protruding portions of the non-conductive cap are designed to pass through the bracket and be inserted into coupling holes, creating a self-aligning and self-securing mechanism. This self-service design reduces the need for complex external fastening operations and simplifies the assembly process.
Solution Approach 2:
The non-conductive cap acts as an intermediary component between the bracket and the antenna module. It provides both mechanical support through its protruding portions and electrical isolation, simplifying the overall assembly by combining multiple functions in a single intermediate element.
3Area of stationary object
If a bracket with coupling holes is used to secure the antenna module, then the attachment area increases, but the device structure becomes more complex
Solution Approach 1:
The bracket serves multiple functions: it provides structural support for the antenna module, offers positioning through mounting holes, and enables secure attachment via coupling holes. This multi-functionality increases the effective attachment area while avoiding the need for separate components for each function.
Solution Approach 2:
The bracket is merged with the housing structure, and the non-conductive cap is integrated with the side wall recess. This merging of components creates a unified fixing system that increases attachment area without proportionally increasing structural complexity.
