Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in efficiently and reliably removing trays or external components, such as SIM cards and memory cards, which are often cumbersome and require manual operation.
Innovation Solution
The electronic device incorporates a tray with a protrusion and an actuator that generates power to remove the tray from sockets, utilizing an inclined surface and a power source to facilitate automatic extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to remove trays or external components, then device complexity is reduced, but ease of operation deteriorates and productivity decreases
Solution Approach 1:
The tray removal system operates automatically without requiring user intervention. The actuator self-activates to push the tray out through the opening, and the tray then self-ejects through the opening due to the pushing force, eliminating the need for manual removal operations
Solution Approach 2:
The manual mechanical operation of removing trays is replaced by an automated actuator system. The actuator converts electrical or other forms of energy into mechanical pushing force, substituting the manual mechanical action with an automated mechanical system
2Productivity
If manual operation is used to remove trays or external components, then device complexity is reduced, but productivity deteriorates
Solution Approach 1:
The system performs tray removal automatically without requiring user time or effort. The actuator self-activates to push the tray out, and the tray self-ejects through the opening, enabling rapid and efficient tray removal operations that improve productivity
Solution Approach 2:
The actuator is pre-positioned inside the device to push the tray out through the opening. This preliminary positioning allows the tray removal process to begin immediately when activation is needed, eliminating delays associated with manual intervention
3Ease of operation
If an actuator with inclined surface is used to remove the tray, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The actuator incorporates an inclined surface that converts linear pushing motion into a guided ejection motion. The inclined surface creates a mechanical advantage that smoothly guides the tray out through the opening, making the operation easier while integrating the mechanism compactly into the device structure

Function Achieved in This Case
Enables easy and automated removal of trays or external components, enhancing user convenience and reducing manual intervention.
Implementation Method 1
a protrusion provided at another end of the tray body in the longitudinal direction and including a first inclined surface provided on one side of the protrusion. In a state in which the tray is inserted into the sockets, the actuator is configured to press the first inclined surface in a width direction of the tray and is configured to remove the tray from the sockets in the longitudinal direction of the tray

AI summary
An electronic device includes: a housing including an opening and sockets; a tray to be insertable into the sockets or removable from the sockets through the opening; and an actuator to generate power to remove the tray from the sockets. The tray includes: a tray body including a space for inserting an external component into the sockets in a longitudinal direction; a tray head provided at one end of the tray body in the longitudinal direction; and a protrusion provided at another end of the tray body in the longitudinal direction and including an inclined surface provided on one side of the protrusion. When the tray is inserted into the sockets, the actuator presses the inclined surface in a width direction of the tray and removes the tray from the sockets in the longitudinal direction of the tray.
