Card Socket Component with Elastic Ejection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone designs require a push pin to separate the card holder from the housing for removing an information card, making the process inconvenient.
Innovation Solution
A card socket component with a housing, bearing plate, card holder, and elastic component, featuring a lever and elastic member that provides an opposite elastic force to push the card holder out when the baffle is unlocked, allowing for easy card removal without additional tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a push pin is used to separate the card holder from the housing, then the card holder can be removed, but the operation becomes inconvenient and requires additional tools
Solution Approach 1:
The card holder is designed with an integrated elastic component that automatically pushes the card holder out when the locking member is released. The elastic member stores energy during insertion and releases it to eject the card holder, making the system self-serving without requiring external push pins or tools.
Solution Approach 2:
The elastic component is pre-loaded during the card holder insertion process. As the card holder is pushed in, the elastic member is compressed and stores potential energy, preparing the system for automatic ejection when the lock is released, eliminating the need for separate removal tools.
2Reliability
If a locking mechanism is added to secure the card holder, then the card holder is firmly held, but the structure becomes more complex
Solution Approach 1:
The locking mechanism is merged with the elastic component into a single integrated assembly. The locking member, elastic member, and lever work together as one unit, combining the securing function with the ejection mechanism to avoid adding separate complex locking structures.
Solution Approach 2:
The complex traditional locking mechanism is replaced by extracting only the essential locking function and implementing it through a simple locking member that engages with a locking slot, while the elastic component handles the securing force, simplifying the overall structure.
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
Facilitates convenient and tool-free removal of the card holder from the housing, enhancing user experience by simplifying the process of taking out the information card.
Implementation Method 1
The elastic member is elastically disposed on the bearing plate in a sliding direction of the card holder... When the locking member rotates to make the limiting protrusion of the locking member separated from the locking slot, the baffle body is pushed out from the housing under the action of the elastic force of the lever

AI summary
A card socket component for an electronic device includes a housing, a bearing plate fixed in the housing, a card holder, and an elastic component. The housing has a through hole. The card holder has a tray and a baffle connected to the tray. The tray passes through the through hole of the housing, and is slidably connected to the bearing plate. The elastic component includes an elastic member and a lever. The elastic member is elastically disposed on the bearing plate in a sliding direction of the card holder. The lever is rotatably connected to the bearing plate, a first end of the lever abuts against the elastic member, and a second end of the lever is able to abut against the tray. Also provided is an electronic device.
