Connector Lock Arm Structure for Moving Plate Position Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors have separate structures for restricting the movement of a moving plate from an initial position to a connection position and for restricting its forward movement, which complicates the configuration of the moving plate.
Innovation Solution
A connector design that incorporates a resiliently deformable lock arm with a locking projection and a stopping projection, where the moving plate has a lock portion that faces both projections to simultaneously restrict movement to the connection position and forward movement, simplifying the plate's configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate restricting structures are provided for restricting movement from initial position to connection position and for restricting forward movement, then the connector can maintain reliable position control, but the configuration of the moving plate becomes complex
Solution Approach 1:
The patent combines two separate restricting structures into a single integrated lock portion on the moving plate. The lock portion includes a first restricting structure with a locking projection that engages with a lock groove on the lock arm to prevent movement from initial to connection position, and a second restricting structure with a stopping projection that engages with a stop groove on the lock arm to prevent forward movement. This merging simplifies the moving plate configuration while maintaining both position control functions.
Solution Approach 2:
The lock arm serves multiple functions: it acts as both a locking mechanism (with lock groove engaging the locking projection) and a stopping mechanism (with stop groove engaging the stopping projection). This multi-functionality allows a single component to perform what would traditionally require separate structures, thereby simplifying the overall design while ensuring reliable position control.
2Reliability
If multiple separate restricting structures are implemented, then comprehensive movement control is achieved, but the number of components and assembly steps increases
Solution Approach 1:
The patent merges multiple restricting structures into a single integrated lock portion that includes both the locking projection and stopping projection. This reduces the number of separate components that need to be manufactured and assembled, while still providing comprehensive movement control through the two distinct engagement points with the lock arm.
Solution Approach 2:
While combining structures, the patent segments the functional elements (locking projection, stopping projection, lock groove, stop groove) into distinct but integrated features. This segmentation allows for clear manufacturing processes and assembly steps while maintaining the simplified overall configuration.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for a simplified configuration of the moving plate by consolidating the restricting structures, reducing interference resistance, and enabling smooth movement between positions while maintaining effective connection and disconnection.

AI summary
A receptacle 47 includes a resiliently deformable lock arm 55 extending in a front-rear direction. The lock arm 55 includes a locking projection 57 projecting into the receptacle 47 from a rear end part and a stopping projection 59 projecting into the receptacle 47 from a location forward of the locking projection 57. The moving plate 42 includes a lock portion 76 at a position corresponding to the lock arm 55. A rear surface of the lock portion 76 faces the locking projection 57 to restrict a movement of the moving plate 42 to a connection position and a front surface of the lock portion 76 faces the stopping projection 59 to restrict a forward movement of the moving plate 42 when the moving plate 42 is at the initial position.
