Movable Tray and Stopper Mechanism for SIM Card Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional card-receiving devices in portable electronic devices, such as mobile phones, require simultaneous removal and replacement of the SIM card and the entire device, making SIM card swapping difficult and prone to damage and dropping.
Innovation Solution
A card-receiving device with a moveable tray and a stopper mechanism that allows the SIM card to be easily swapped by moving the tray between positions, utilizing a resilient member to provide a recovery force for secure card ejection and insertion, preventing the card from being dropped during removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the SIM card and entire card-receiving device are removed simultaneously to swap the SIM card, then the card-receiving device structure is simple, but the SIM card is difficult to remove and easily dropped and damaged
Solution Approach 1:
The card-receiving device is segmented into a stationary card-receiving device and a movable tray that holds the SIM card. The tray can be independently ejected from the device, allowing the SIM card to be accessed and removed separately from the entire card-receiving device. This segmentation resolves the contradiction by enabling easy SIM card removal while maintaining a relatively simple overall device structure.
Solution Approach 2:
The tray holding the SIM card is extracted as a separate removable component from the card-receiving device. When SIM card swapping is needed, only the tray needs to be ejected and removed, not the entire card-receiving device. This extraction principle makes SIM card removal easier and prevents the card from being dropped during the process, as the tray provides a stable holding structure.
2Ease of operation
If a moveable tray with stopper mechanism is used to facilitate SIM card swapping, then the SIM card swapping becomes easier and card damage is prevented, but the device complexity increases
Solution Approach 1:
The stopper mechanism is designed to automatically engage with the SIM card when the tray is inserted, and automatically release when the tray is ejected. The resilient member provides automatic reset functionality, pushing the stopper back into its original position after the SIM card is removed. This self-service mechanism reduces the need for complex control systems while maintaining ease of operation.
Solution Approach 2:
The stopper is designed as a movable component that can dynamically adjust its position between engaged and disengaged states. The resilient member provides dynamic reset functionality, allowing the stopper to automatically return to its initial position after use. This dynamic design enables easy SIM card swapping while keeping the mechanical structure relatively simple compared to powered or electronically controlled systems.

Implementation Method 1
a resilient member (240) connected to the chassis (124) and the tray (210), wherein when the tray moves to the first position, the resilient member (240) is deformed; when the tray moves to the second position from the first position, the resilient member (240) pushes the tray (210) and the SIM card (201)

AI summary
A card-receiving device for containing a card comprises a chassis, a tray and a stopper. The tray is disposed on the chassis and moveable between a first position and a second position, wherein the card is disposed on the tray, and moves from the first position to the second position by the tray. When the tray moves to the second position from the first position, the stopper abuts and stops the card.
