Detachable Tray Ejection Structure for Compact Electronic Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in efficiently detaching a tray from a housing, which can lead to reduced space within the device and increased manufacturing complexity.
Innovation Solution
The electronic device incorporates a tray with an elastic member that includes a first hole on the tray's outer surface and a second hole aligned with the first hole within the housing. The elastic member is deformable and configured to hold an external member, allowing the tray to be partially ejected from the housing when the external member is moved.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the tray is detachably coupled to the housing, then the tray can be easily removed for interface chip replacement, but the device structure becomes more complex
Solution Approach 1:
The tray is segmented from the housing as a separate detachable component rather than being integrated. The tray includes a body portion and an elastic member that can be independently removed through the through-hole, allowing interface chip replacement without disassembling the entire device housing.
Solution Approach 2:
The tray extraction mechanism utilizes the through-hole in the housing to allow the tray to be pulled out directly. The elastic member protrudes through the first hole to engage with external members, enabling the tray to be extracted from the housing without complex fastening mechanisms.
2Volume of moving object
If the tray is made detachable, then space within the device is reduced, but the manufacturing process becomes more complex
Solution Approach 1:
The elastic member is integrally formed with the tray body as a single piece, combining the tray structure and the ejection mechanism into one component. This reduces the number of separate parts to manufacture and assemble, simplifying the manufacturing process while maintaining the detachable functionality.
Solution Approach 2:
The elastic member is made from flexible material that can deform during the ejection process. This flexibility allows the tray to be easily inserted and removed through the through-hole without requiring complex mechanical joints or fasteners, reducing manufacturing complexity.
3Ease of operation
If the elastic member is used to hold the external member, then the tray can be ejected smoothly, but the tray structure becomes more complex
Solution Approach 1:
The elastic member serves dual functions: it provides structural support for the tray and simultaneously acts as the ejection mechanism. When external force is applied through the first hole, the elastic member deforms and propels the tray outward, making the tray self-ejecting without requiring separate actuation mechanisms.
Solution Approach 2:
The elastic member changes its physical state from a relaxed position to a deformed position during ejection. This parameter change in the elastic member's shape and position enables the tray ejection function while maintaining a simple overall structure.

AI summary
An electronic device according to one embodiment includes: a housing including a through-hole; a printed circuit board; and a tray which moves to the outside of the through-hole according to movement in the first direction, or of which at least one portion is arranged on the printed circuit board according to movement in the second direction in order to be inserted into the through-hole, where the tray includes: a first accommodation hole for insertion of an external member penetrating the outer surface of the tray; and an elastic member which includes an insertion hole, and which can be deformed by the external member, and the tray is inserted into the insertion hole so as to be movable to the outside of the through-hole by movement in the first direction of the external member in contact with the elastic member.
