Sliding Tray Mechanism for Compact Electronic Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tray devices in electronic devices occupy significant space and complicate the process of attaching and detaching external parts, such as memory cards and SIM cards, due to their complex structure and large size.
Innovation Solution
A tray device with a double sliding mechanism that includes a first body for accommodating external parts and a second body that slides with the first body, allowing for reduced space occupation and easy attachment/detachment of external parts by using a tray socket and ejector system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional tray and tray socket structure is used, then the tray can be separated by pressing an ejector, but the electronic device occupies significant space and has a complex structure
Solution Approach 1:
The tray is divided into a first body that detachably couples with the tray socket and a second body that slidably couples with the first body. This segmentation allows the tray to be ejected through a simpler mechanism while maintaining the functionality of external part attachment and detachment, thereby reducing overall structural complexity.
Solution Approach 2:
The second body is nested within the first body, with the second body slidably coupled inside the first body along the insertion direction. This nesting arrangement reduces the overall space required for the tray structure while preserving the ejection functionality through the ejector pressing the second body.
2Ease of operation
If a conventional tray and tray socket structure is used, then the tray can be separated by pressing an ejector, but the electronic device occupies significant internal space
Solution Approach 1:
The second body is nested within the first body, reducing the overall volume required for the tray structure. When the ejector presses the second body, it slides relative to the first body to achieve tray ejection, maintaining operational ease while minimizing internal space occupation.
Solution Approach 2:
The second body is designed to slidably couple with the first body, allowing dynamic movement during the ejection process. This dynamic mechanism enables the tray to be separated with a simpler, more space-efficient structure compared to conventional rigid tray designs.
3Volume of moving object
If the tray structure is simplified to reduce space, then internal occupation space is minimized, but the ease of accessing and replacing external parts may be compromised
Solution Approach 1:
The tray is segmented into two bodies with different functions: the first body detachably couples with the tray socket to provide stable external part accommodation, while the second body slidably couples to enable easy ejection. This segmentation maintains ease of accessing external parts while minimizing internal space occupation.
Solution Approach 2:
The second body acts as an intermediary between the ejector and the first body. When the ejector presses the second body, it translates this force into sliding motion relative to the first body, thereby enabling tray ejection without requiring direct complex mechanisms at the tray socket interface, thus preserving ease of operation with reduced space.

AI summary
Disclosed is an electronic device including a housing; a tray socket provided in the housing; a tray configured to be inserted into the tray socket along an insertion direction; and an ejector configured to be connected to the tray socket and configured to press and separate the tray in a separation direction opposite to the insertion direction. The tray includes a first body configured to detachably couple with the tray socket including a seating portion configured to accommodate and support an external part; a second body configured to slidably couple with the first body along the insertion direction; a tray cover configured to be connected to the first body and exposed to the outside based on a state in which the tray is inserted into the tray socket and in which a pin insertion hole configured to enable communication between the second body and the outside is formed.
