Fully Embedded Electronic Plug-in Card Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic plug-in cards require complex and costly eject mechanisms, leading to increased risk of damage and inconvenience due to protruding components, especially when used in portable devices.
Innovation Solution
A fully embedded electronic plug-in card design with a main body that fits entirely within the socket, utilizing elastic guide arms and a recessed structure for easy insertion and removal without protruding parts, eliminating the need for a card eject mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a card eject mechanism is added to the plug-in socket to eject the card, then the card can be removed, but the cost increases and the structure becomes more complex
Solution Approach 1:
The patent extracts the card removal function from the plug-in socket by providing a recessed structure directly on the card body. Users can directly pull the card out through the recessed structure without needing an eject mechanism in the socket, thereby simplifying the socket structure while maintaining ease of operation.
Solution Approach 2:
The recessed structure on the card body enables self-service removal. The card carries its own removal interface (recessed structure) that allows users to directly pull it out, making the system self-sufficient without requiring additional ejection components in the socket.
2Ease of operation
If the flash drive is designed to protrude out of the USB plug-in socket, then it can be easily removed, but the protruding portion may be bent or broken by hitting
Solution Approach 1:
The card body is fully nested within the plug-in socket during normal operation, with no protruding parts. The recessed structure is positioned such that when the card is inserted, it sits flush with or below the socket surface, eliminating exposed portions that could be damaged by impact while still allowing removal through the recessed structure.
3Reliability
If the card is designed to be fully embedded in the plug-in socket, then the risk of being hit is eliminated, but the card cannot be easily removed
Solution Approach 1:
The recessed structure serves as an intermediary element that mediates between the fully embedded card body and the user's removal action. It provides a localized interface for finger engagement that extends slightly from the card surface, enabling easy removal without requiring the entire card to protrude and without compromising the protective embedded design.
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 ensures the card can be continuously plugged in without risk of damage, simplifies usage by allowing easy pull-out through a recessed structure, reduces costs, and minimizes the volume of the plug-in socket while avoiding the complications of traditional eject mechanisms.
Implementation Method 1
the plug-in socket contains a plurality of elastic guide arms

AI summary
A fully embedded electronic plug-in card pluggable into a slot of a plug-in socket having a plurality of elastic guide arms includes a main body, a plurality of conductive plates and a recessed structure. The main body can be wholly plugged into the plug-in socket without protruding out from the plug-in socket. The conductive plate is mounted onto the main body, and exposed from a side of the main body, and each conductive plate is electrically coupled to each respective elastic guide arm. The recessed structure is disposed on the main body and at a position corresponding to the slot of the plug-in socket. The electronic plug-in card can be plugged into the plug-in socket all the time to save the trouble and inconvenience of plugging the card for use or unplugging the card for removal.
