Card Socket Hinge Noise and Breakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tray type card sockets experience unwanted noise due to component collisions and are prone to hinge breakage from excessive force during assembly and use.
Innovation Solution
Incorporation of movement preventing means, such as stepped portions and recesses, to restrict the movement of the ejecting hinge and bar components, and a hinge breakage preventing protrusion to minimize force on the hinge shaft, thereby reducing noise and preventing breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If components are assembled to be movable to implement ejecting mechanism, then ejecting function is achieved, but rattle noise is generated due to collision between components
Solution Approach 1:
The patent applies preliminary action by pre-positioning the ejecting bar and ejecting hinge portion in specific locations before the ejecting operation occurs. The ejecting bar is installed in the socket housing to be movable in forward and backward directions, and the ejecting hinge portion is coupled to the rear end of the socket housing. This preliminary positioning ensures that when vibration occurs, the components are already in optimal positions that prevent collision and rattle noise, while still allowing the ejecting function to operate when needed.
2Ease of operation
If hinge structure is used to support ejecting hinge portion, then rotatable movement is enabled, but hinge shaft breaks due to strong force from pressure of ejecting bar
Solution Approach 1:
The patent applies the intermediary principle by introducing the housing hinge shaft as a mediator between the ejecting bar and the ejecting hinge portion. The housing hinge shaft is installed at the rear end of the inside of the socket housing to rotatably support the ejecting hinge portion. This intermediary component distributes and manages the strong forces exerted during rotation, preventing direct stress concentration that would cause breakage while still enabling the necessary rotatable movement for the ejecting function.
3Adaptability or versatility
If components are assembled without fixing to allow movement, then ejecting mechanism functions, but collision between components causes rattle noise
Solution Approach 1:
The patent applies dynamics by designing the ejecting bar to be movable in forward and backward directions within the socket housing, and the ejecting hinge portion to be rotatably coupled to the housing. This dynamic design allows the components to move and rotate as needed for the ejecting function while maintaining controlled movement paths that prevent unwanted collisions and rattle noise during normal operation and vibration conditions.

AI summary
Disclosed is an electronic device card socket capable of preventing the breakage of a hinge and preventing noise (static), which is caused by movement between respective parts, in the tray-type card socket. The electronic device card socket according to one embodiment of the present disclosure includes a socket housing, a socket cover, an ejecting hinge part, and ejecting bar, and a movement preventing means. The socket housing has a space into which a tray equipped with a card is inserted. The socket cover is provided at the upper part of the socket housing. The ejecting hinge part is rotatably hinge-coupled to one side of the socket housing so as to push the tray forward and separate the same when the ejecting hinge part rotates. The ejecting bar is provided at the other side of the socket housing so as to move in the forward and backward directions, and is connected to the ejecting hinge part so as to rotate the ejecting hinge part when the ejecting bar moves forward and backward. The movement preventing means prevents the movement of the ejecting hinge part and/or the ejecting bar when vibration is generated between the parts of the card socket.
