Stacked Dual SIM Card Holder with Sliding Drawer Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional chip card holders for dual-SIM mobile terminals occupy a large area due to side-by-side receiving spaces, which is inefficient in design.
Innovation Solution
A chip card holder with a drawer mechanism that allows for simultaneous attachment and easy removal of two chip cards, featuring a base, drawer, and cabinet design with limiting blocks and electrical connectors, enabling stack arrangement and reduced space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If side-by-side receiving spaces are used for dual SIM cards, then both SIM cards can be accommodated, but the area occupied by the chip card holder becomes large
Solution Approach 1:
The patent transitions from a horizontal side-by-side arrangement to a vertical stacked arrangement of SIM card receiving spaces. The first receiving space is positioned above the second receiving space, utilizing the vertical dimension to reduce the horizontal area occupied by the chip card holder while maintaining dual SIM functionality
Solution Approach 2:
The patent implements a drawer mechanism where the drawer containing the second receiving space can be slid out from the base. This nested structure allows the second SIM card holder to be stored within the overall holder structure when not in use, further reducing the occupied area and providing easy access to both SIM cards

AI summary
A chip card holder for holding at least two chip cards is disclosed. The chip card holder includes a base, a drawer slidably attached to the base. The drawer includes at least two receiving spaces, each receiving space for receiving a chip card. The drawer moves relative to the base to make the at least two receiving spaces be exposed out of the base or be received in the base.
