Ejector Mechanism for Removable Modules in Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ejectable component assemblies for electronic devices often require a significant amount of space for the ejector mechanism and can interfere with other device functions due to the placement of the ejector user interface, which is typically near the module ejection opening.
Innovation Solution
The design includes an ejector mechanism with a core and guide that translates user input force into an ejection force, allowing the ejector user interface to be positioned independently of the module housing opening, and the path of force translation can be linear, parallel, perpendicular, or skew, ensuring the mechanism does not interfere with other device functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional ejector mechanism is used with the ejector user interface positioned near the module housing opening, then the ejection function is achieved, but the ejector mechanism takes up valuable real estate within the housing and interferes with other device functions
Solution Approach 1:
The patent repositions the ejector user interface from the traditional location near the module housing opening to a different location on the housing, utilizing spatial dimensionality to separate the interface from the ejection path. This allows the ejector mechanism to be more compact while maintaining full ejection functionality, thereby reducing the space required within the housing.
2Device complexity
If the ejector user interface is positioned through the same housing opening as the module ejection, then the ejection mechanism is simplified, but the interface interferes with the function of the ejectable component assembly
Solution Approach 1:
The patent separates the ejector user interface from the module housing opening, creating distinct functional zones. The ejector mechanism itself remains integrated with the component assembly, while the user interface is positioned independently on the housing, allowing both functions to operate without interference.
3Area of stationary object
If the ejector mechanism is made compact to save space, then housing real estate is preserved, but the mechanism may require more complex design to achieve the same ejection force
Solution Approach 1:
The patent introduces a force transmission element (such as a spring or lever mechanism) that acts as an intermediary between the user interface and the ejector component. This intermediary allows the compact design to achieve sufficient ejection force through mechanical advantage, balancing space efficiency with functional effectiveness.

Function Achieved in This Case
This configuration allows for efficient ejection of removable modules without occupying additional space and minimizes interference with other device functions, enhancing the usability and design of electronic devices.
Implementation Method 1
The ejector mechanism may receive a user input force at an ejector user interface through a housing of the electronic device, translate that user input force into an ejection force, and apply that ejection force onto the tray and/or module

AI summary
An electronic device may be provided with an ejectable component assembly having a connector that can receive and retain a removable module within a housing of the electronic device. The ejectable component assembly may also be provided with an ejector mechanism for at least partially ejecting the removable module from the connector. The ejector mechanism may receive a user input force at an ejector user interface, translate that user input force into an ejection force, and apply that ejection force onto the removable module for ejecting the module. The ejector user interface may be provided at any suitable position of the housing that may not interfere with other functions of the device. The path along which the ejector mechanism translates the user input force into the ejection force between the ejector user interface and the removable module may be provided in any suitable way throughout the device.
