Rotating Wedging Arm Connector for Vibration-Resistant Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic device connectors, such as those in dash cams, tend to separate due to vehicle vibrations or unintended cable pulling, necessitating an additional mechanism to maintain connection stability.
Innovation Solution
A connector combination structure featuring a first connector with a wedging portion and a second connector with a wedging arm that can be rotated between positions to wedge or release, utilizing an elastic unit or inherent elastic force to secure or release the connection, allowing for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional connector connection is used, then the structure is simple, but the connection stability is poor due to vehicle vibrations or cable pulling
Solution Approach 1:
The patent employs a dynamic wedging arm that can rotate between a first arm position (for securing) and a second arm position (for releasing). This dynamic element allows the connector to transition between locked and unlocked states, providing both stability during use and ease of disconnection. The wedging arm's rotational movement enables it to engage with or disengage from the wedging portion, resolving the contradiction between connection stability and operational simplicity.
Solution Approach 2:
The elastic unit automatically returns the wedging arm to the first arm position after being pushed to the second arm position, securing the connection without requiring additional components or complex mechanisms. The elastic force provides self-service by maintaining the locked state through the natural elastic recovery of the unit, reducing the need for extra structural elements while ensuring reliable connection stability.
2Reliability
If an additional mechanism is added to prevent separation, then the connection stability improves, but the device complexity and cost increase
Solution Approach 1:
The patent combines the wedging arm, operation portion, and elastic unit into a single integrated component that is formed as one piece. This merging of multiple functional elements into a single structure reduces the number of parts that need to be manufactured and assembled, thereby simplifying the manufacturing process and reducing costs while still providing the additional mechanism needed for connection stability.
Solution Approach 2:
The integrated component serves multiple functions: the wedging arm provides the locking mechanism, the operation portion enables user actuation, and the elastic unit provides the return force. By combining these functions into a single multi-functional component, the patent avoids the need for separate parts for each function, reducing manufacturing complexity and cost while maintaining connection stability.
3Reliability
If a secure connection mechanism is implemented, then the connection stability improves, but the ease of disconnection may be reduced
Solution Approach 1:
The wedging arm's ability to rotate between two distinct positions provides a dynamic solution that balances security and ease of operation. When the user pushes the operation portion, the wedging arm rotates to the second arm position, releasing the wedging portion and allowing easy disconnection. During normal use, the arm remains in the first position, providing secure connection. This dynamic positioning resolves the contradiction between secure connection and ease of disconnection.
Solution Approach 2:
The elastic unit automatically returns the wedging arm to the secured position after release, ensuring that the connector is reliably locked without requiring the user to manually secure it. This self-service mechanism maintains connection stability while allowing simple one-handed operation for disconnection, as the user only needs to push the operation portion without worrying about subsequent securing steps.
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
Enhances the connection stability between the first and second connectors, preventing unexpected separation while allowing for easy disconnection by user operation, resulting in a simple, cost-effective, and easily assembled design.
Implementation Method 1
the elastic unit exerts an elastic force on the wedging arm, and the wedging arm tends to move from the second arm position to the first arm position due to the elastic force
Implementation Method 2
When the wedging arm is located in the first arm position, the wedging arm is adapted to wedge the wedging portion
