Housing Combination With Integrated Shielding Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional housing combinations for portable electronic devices occupy more internal space due to the need for a thick support portion made of plastics, which does not fully utilize the available space.
Innovation Solution
A housing combination featuring a metal piece with guiding flanges and a shielding enclosure that serves as both a support and shielding component, allowing the SIM card connector and support portion to be exposed from the receiving hole, reducing the distance between the housing and the printed circuit board and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the support portion is made thicker to secure strength, then the strength of the support portion is improved, but the inner space of the portable electronic device is reduced
Solution Approach 1:
The patent merges the support portion and shielding enclosure into a single integrated component. The shielding enclosure serves dual functions: providing electromagnetic shielding and supporting the SIM card. This integration eliminates the need for a separate thick support portion, thereby maintaining strength while preserving inner space.
Solution Approach 2:
The shielding enclosure is designed to perform multiple functions simultaneously: electromagnetic shielding, SIM card support, and structural reinforcement. By making the shielding enclosure multi-functional, the patent avoids adding extra components that would consume valuable inner space.
2Strength
If the support portion is made thicker to secure strength, then the strength of the support portion is improved, but the distance between housing and printed circuit board is increased
Solution Approach 1:
The support portion and shielding enclosure are merged into one component, which reduces the overall distance between the housing and the printed circuit board. The shielding enclosure extends downward from the housing to provide support, eliminating the need for additional thickness that would increase the distance.
3Strength
If a separate support portion and shielding enclosure are used, then the strength and shielding functions are improved, but the device complexity is increased
Solution Approach 1:
The patent combines the support portion and shielding enclosure into a single integrated component. This merging reduces the number of parts that need to be manufactured, assembled, and secured, thereby simplifying the overall device structure while maintaining both strength and shielding functions.

AI summary
A housing combination includes a housing (51) and a shielding enclosure (55). The housing has a peripheral wall and a receiving hole (511). The peripheral wall surrounds the receiving hole configured for receiving a surface contact card. A guiding element (52) is positioned in at least one part of the peripheral wall of the receiving hole. The shielding enclosure is disposed at one side of the housing, one part of the shielding enclosure exposed from the receiving hole configured for supporting the surface contact card.
