Card Socket Baffle Mechanism for Tool-Free Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone card sockets require an auxiliary tool like a push pin for card removal, making the process inconvenient, and if no tool is available, card removal is impossible.
Innovation Solution
A card socket component with a baffle mechanism that uses an elastic component to facilitate card removal without tools, where the baffle is slid to unlock the card holder from the housing, allowing semiautomatic ejection of the card.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional card socket design is used, then the card holder is securely locked in the housing, but an auxiliary tool is required for card removal, making operation inconvenient
Solution Approach 1:
The baffle is nested within the card holder, forming a compact integrated structure. When the baffle moves relative to the card holder, it triggers the locking mechanism through the interaction between the groove and protrusion, achieving card ejection without external tools while maintaining structural compactness
Solution Approach 2:
The card holder transitions from a static locked state to a dynamic ejection state through the movable baffle. The groove-protrusion mechanism allows the card holder to move between locked and unlocked positions, enabling automatic ejection when the baffle is pushed, thus improving operational convenience without requiring auxiliary tools
2Reliability
If the card holder is securely locked in the housing, then reliability is improved, but the card cannot be removed without an auxiliary tool
Solution Approach 1:
The card holder incorporates a self-service ejection mechanism where the baffle, when pushed by the user, automatically disengages the groove-protrusion locking mechanism. This allows the card holder to eject itself without requiring external auxiliary tools, maintaining reliability while enabling easy operation
Solution Approach 2:
The groove and protrusion are pre-configured in specific positions to ensure reliable locking during normal operation. When the baffle is pushed, these pre-positioned features automatically interact to trigger the ejection sequence, ensuring that the card holder transitions smoothly from locked to unlocked state without requiring additional tools or complex operations
3Ease of operation
If no locking mechanism is used, then card removal is easy, but the card holder may separate during falls or impacts, reducing reliability
Solution Approach 1:
The locking mechanism transitions dynamically between locked and unlocked states based on user input. During normal operation, the groove-protrusion features maintain a secure locked state to prevent accidental separation during falls or impacts. When the baffle is pushed, the mechanism dynamically switches to an unlocked state, allowing easy card removal without compromising stability during normal use

AI summary
Disclosed is a card socket component, including a housing, a bearing plate, a cover, an elastic component and a card holder containing a tray and a baffle. The housing has a sliding groove and a through hole, a protrusion is disposed at an end of the sliding groove. The cover and the bearing plate define a receiving space directly facing the through hole. The elastic component is disposed in the receiving space and is configured to provide an opposite elastic force for the tray when the tray arrives at a bottom of the receiving space. A groove is provided on an end side surface of the baffle. When the baffle is at a first staying position, the protrusion is located outside the groove. When the baffle is at a second staying position, the protrusion is received in the groove. Also disclosed is an electronic device.
