Elastic Seal Member for Tray Ejection in Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile electronic device accessories with seal members have limited mobility and flexibility, which can cause issues when the device is dropped, leading to the accessory sticking to the socket and preventing the tray from ejecting properly.
Innovation Solution
An electronic device design that incorporates a seal member with a first open end and a second closed end, configured to extend or contract based on a tray ejector pin, along with a guide unit, pressing member, pressure transmission unit, or pressure leaf spring, to ensure waterproof and dustproof functionality while allowing easy tray ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a seal member is installed or inserted into a separate accessory, then waterproof and dustproof function is improved, but mobility and flexibility are reduced
Solution Approach 1:
The seal member is designed with elastic properties allowing it to dynamically change shape. It can be compressed when the tray ejector pin passes through, and then returns to its original shape to maintain the seal, providing both protection and mobility
Solution Approach 2:
The physical state of the seal member changes from a compressed state (when pin passes through) to an extended state (when sealing), altering its length and shape parameters to fulfill different functional requirements at different times
2Object-affected harmful factors
If a seal member is installed or inserted into a separate accessory, then waterproof and dustproof function is improved, but the accessory may stick to the socket when the device is dropped
Solution Approach 1:
The elastic seal member can dynamically deform to absorb impact forces when the device is dropped, preventing the accessory from sticking to the socket while maintaining the seal
Solution Approach 2:
The elastic properties of the seal member provide built-in cushioning capability that absorbs shock and impact forces before they can cause the accessory to stick to the socket
3Ease of operation
If the seal member is pressed by the tray ejector pin, then the tray can be ejected, but the seal member may lose its sealing capability
Solution Approach 1:
The seal member dynamically changes shape during ejection (compressed) and then returns to its original sealing shape, allowing both ejection and sealing functions to be fulfilled at different times
Solution Approach 2:
The seal member temporarily sacrifices its sealing shape during ejection (discarding the sealed state) but recovers its sealing capability after the ejection process completes
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced mobility and flexibility to the seal member, ensuring effective waterproof and dustproof protection while maintaining the ability to easily eject the tray, even after a drop, by transferring force from the tray ejector pin to the actuator of the socket.
Implementation Method 1
The seal member is configured to be extended or contracted based on whether the seal member is pressed by a tray ejector pin passing through the opening

AI summary
An electronic device with a seal member is provided. The electronic device includes a tray configured to slide in and out of the electronic device, an opening, (e.g., a hole) formed at one side of the tray, for communicating outside of the electronic device, a socket disposed in the electronic device, the tray slides into or from the socket, and a seal member, disposed between the opening and the socket, for performing a waterproof and dustproof function. Various types of the seal member may be implemented.
