Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of antenna modules in electronic devices for 5G communication often compromises the internal space due to the need for shielding and fixing, which limits the device's ability to operate in various frequency bands efficiently.
Innovation Solution
An electronic device design that utilizes a conductive shielding member as both a shield for a second antenna (e.g., mmWave module) and an additional antenna, allowing it to be fixed to the housing while using its bending parts to shield and secure the second antenna, thereby optimizing space and frequency band operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate fixing member and shielding member are used to fix the antenna module to the housing, then the antenna module is securely fixed and shielded, but the internal space of the electronic device is reduced
Solution Approach 1:
The patent combines the fixing member and shielding member into a single integrated component. The fixing member includes conductive portions that serve both as structural fixing elements and as shielding members that reduce electromagnetic interference. This merging eliminates the need for separate shielding components, thereby preserving internal space while maintaining both fixing reliability and EMI shielding effectiveness.
Solution Approach 2:
The fixing member is designed with multi-functionality, serving both as a mechanical fixing component and as an electromagnetic shielding component. The conductive portions of the fixing member provide both structural support for securing the antenna module and electromagnetic shielding to reduce interference with other electronic components, thus achieving dual functionality with a single component.
2Object-affected harmful factors
If a shielding member is added to shield the antenna module, then electromagnetic interference with other electronic parts is reduced, but the device complexity increases
Solution Approach 1:
The shielding function is merged into the fixing member itself. The conductive portions of the fixing member act as shielding members, eliminating the need for separate shielding components. This integration reduces the number of parts and simplifies the overall structure while maintaining effective electromagnetic interference reduction.
Solution Approach 2:
The fixing member is designed to perform multiple functions simultaneously: mechanical fixing of the antenna module and electromagnetic shielding. This multi-functionality approach reduces device complexity by eliminating redundant components while still providing comprehensive EMI protection.
3Reliability
If the antenna module is fixed using a separate fixing member, then the antenna module is securely mounted, but the mounting space is limited
Solution Approach 1:
The fixing member and shielding member are merged into a single integrated component, reducing the total space required for mounting. The conductive portions of the fixing member serve both fixing and shielding functions, eliminating the need for additional shielding components that would occupy mounting space.
Solution Approach 2:
The fixing member is designed with multi-functionality, providing both mechanical mounting and electromagnetic shielding in a single component. This reduces the overall footprint required for antenna module installation while maintaining secure mounting reliability.
