Integrated Shield Can With Internal Separation Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing miniaturization and functionality of mobile terminals lead to a need for efficient shielding of electronic components from electromagnetic interference (EMI), as multiple shield cans can reduce space utilization due to overlapping side surfaces.
Innovation Solution
A shield can with a separation wall formed by surface-mounted gaskets on the main circuit board within the mobile terminal, which separates electronic elements causing electromagnetic interference, preventing EMI by routing interfering electromagnetic waves to a ground layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple shield cans are used to separate electronic elements, then electromagnetic interference protection is improved, but space utilization deteriorates due to overlapping side surfaces
Solution Approach 1:
The patent combines multiple shield cans into a single integrated shield can structure with internal separation walls. Instead of using separate shield cans for different electronic elements, the invention creates one unified shield can that contains multiple partition walls to separate sensitive components, thereby eliminating overlapping side surfaces and improving space utilization while maintaining EMI protection.
Solution Approach 2:
The patent applies segmentation by introducing separation walls within the shield can to divide the internal space into multiple regions. These separation walls create isolated compartments for different electronic elements, allowing EMI protection for each component while using a single outer shield can structure, thus resolving the space efficiency problem.
2Reliability
If multiple shield cans are used to protect electronic components, then shielding effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple separate shield can structures into a single integrated shield can with internal partitions. This consolidation reduces the number of separate components that need to be manufactured, positioned, and connected, thereby simplifying the overall device structure and reducing assembly complexity while maintaining the same level of EMI shielding effectiveness.
3Reliability
If multiple shield cans are used to enclose electronic components, then electromagnetic interference prevention is improved, but manufacturing complexity increases
Solution Approach 1:
The patent combines multiple shield can manufacturing processes into a single fabrication process. By creating one integrated shield can with internal separation walls, the invention eliminates the need to manufacture, test, and assemble multiple separate shield cans, thereby reducing manufacturing complexity and improving ease of production while maintaining comprehensive EMI prevention.
