Card Holding Mechanism Tray Ejection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card holding mechanisms in electronic devices, such as mobile phones and notebook computers, require users to detach the outer cover to remove or replace electronic cards, making the process inconvenient.
Innovation Solution
A card holding mechanism with a stepped through hole and a tray system that uses a torsion spring and sliding components to allow easy insertion and removal of electronic cards without needing to open the device's outer cover, utilizing a tray that can be ejected and retracted using a sliding and rotating mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional card holding mechanism with a fixed receiving space is used, then the card is securely held, but the user must detach the outer cover to access the card, making removal and replacement inconvenient
Solution Approach 1:
The card holding mechanism is segmented into a receiving space and a tray that can be independently ejected. The tray acts as a movable intermediate carrier that can be pulled out from the receiving space, allowing card access without opening the outer cover. This segmentation resolves the contradiction by providing easy card access while maintaining a simple overall structure.
Solution Approach 2:
The tray serves as an intermediary between the user and the card. Instead of directly accessing the card in the fixed receiving space, the user interacts with the tray which can be ejected for card placement and retrieval. This intermediary mechanism enables convenient card handling while keeping the main device structure intact.
2Ease of operation
If the outer cover is detached to access the card holding mechanism, then the card can be accessed, but the device is exposed to damage or contamination
Solution Approach 1:
The tray is extracted as a separate ejection mechanism from the main device body. Users can pull the tray out through a dedicated opening without needing to detach the outer cover, thus accessing the card while keeping the main device protected from damage and contamination.
Solution Approach 2:
The access mechanism is segmented into a dedicated tray ejection path separate from the main device opening. This allows card access through a controlled interface that minimizes exposure of the internal components to external harmful factors.
3Device complexity
If a simple receiving space with elastic sheet is used, then the structure is simple, but the card cannot be easily removed or replaced without opening the device
Solution Approach 1:
The tray is designed as a dynamic component that can move between a retracted state (when inserted into the receiving space) and an ejected state (when pulled out for card access). This dynamic mechanism adds ease of operation while maintaining structural simplicity through a single sliding motion.
Solution Approach 2:
The tray is pre-positioned within the receiving space, ready to be ejected when needed. This preliminary arrangement allows users to quickly access cards by simply pulling the tray out, eliminating the need to disassemble the device while maintaining a simple overall structure.

Function Achieved in This Case
Enables convenient and easy insertion and removal of electronic cards, improving user accessibility and reducing the risk of damage or contamination, while maintaining the cards securely within the device.
Implementation Method 1
a tray (38) that can be inserted into and ejected from the lower cover (20) through the stepped through hole (213), wherein an operating component (32) is slidably installed on the first sidewall (203)... a torsion spring and sliding components to allow easy insertion and removal of electronic cards

AI summary
An electronic device includes a housing, and a card holding mechanism for holding an electronic card. The housing defines a through hole, and the card holding mechanism may be inserted into the housing via the through hole. The card holding mechanism includes a tray for receiving the electronic card, an operating component, and a transmission component. The operating component moves from a latched position to an unlatched position, the transmission component is driven by the operating component to rotate and drive the tray to eject from the housing.
