Adapter Device Link Mechanism for Stable Connector Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adapter devices face issues with stable insertion and detachment of connectors due to applied forces being misaligned, leading to potential damage or contact failure, which reduces the reliability of the connection.
Innovation Solution
An adapter device with a movement direction conversion unit, comprising a first link mechanism and a second link mechanism, converts operation forces into uniform insertion and detachment directions, ensuring the connector moves in a stable manner by using an operation lever, slider, and inclined surfaces to align forces correctly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adapter-side connector is pivoted around the fastened one side serving as the pivot axis, then the adapter device can be attached to the main body device, but insertion and detachment are performed with an inclination with respect to the insertion and detachment direction of the main body-side connector
Solution Approach 1:
A direction conversion unit is introduced as an intermediary mechanism between the adapter-side connector and the main body-side connector. This unit converts the pivoting motion into linear insertion and detachment motion, ensuring that the connector moves in the correct direction without inclination, thus maintaining connection reliability while enabling easy attachment operation.
2Ease of operation
If a user slides the adapter device to cause the adapter device to be engaged with the connector, then the adapter device can be attached, but a large force is required during insertion and detachment of the connector
Solution Approach 1:
The attachment mechanism transitions from a static sliding motion to a dynamic pivoting motion. By allowing the adapter device to pivot around the fastened side, the user can apply force in a more convenient direction, and the direction conversion unit ensures this motion is properly translated into connector insertion and detachment without requiring excessive force.
3Ease of operation
If uneven force is applied to the connector, then the adapter device can be attached, but the connector may be damaged or deformed, or contact failure may occur
Solution Approach 1:
The direction conversion unit serves as a mediator that ensures uniform force distribution to the connector. By converting the pivoting motion into linear motion, it prevents uneven force application that could damage the connector or cause contact failure, while still allowing easy attachment operation.
Solution Approach 2:
The mechanism is designed to prevent uneven force application before it can damage the connector. The direction conversion unit proactively guides the motion along the correct path, preventing misalignment and uneven force distribution that could lead to connector damage or contact failure.

AI summary
In an attachment stage 20 of an adapter device 10, a fastening unit 221 fastened to a main body device is provided on an attachment surface 21 in advance. A connector 55 is provided on a housing 50. Further, the adapter device 10 is provided with a movement direction conversion unit configured to convert a movement in an operation direction of an operation lever 41 into an insertion and detachment direction of the connector, and move forward and backward the housing 50 in the insertion and detachment direction of the connector 55 with respect to the attachment stage 20 in accordance with the operation force. In the movement direction conversion unit, a first link mechanism converts the movement in the operation direction of the operation lever 41 into a movement in a surface direction of the attachment surface 21 of a hook unit 321f, and a second link mechanism converts the movement in the surface direction of the hook unit 321f into the movement in the insertion and detachment direction of the connector of the housing 50 with respect to the attachment stage 20. The hook unit 221f of the fastening unit 221 is fastened to the main body device and the operation lever 41 is operated, so that the insertion and detachment operation of the connector can be performed in a stable manner.
