Rotating Pin Mounting Mechanism for Misaligned Plastic Plug Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting mechanisms for plastic plugs in housing holes face inefficiencies due to misalignment issues, requiring pin position adjustments for smooth insertion, which lowers mounting efficiency.
Innovation Solution
A mounting mechanism comprising a base, a pin, a first driving member (cylinder), a support member, a second driving member (motor), guiding member, and connection assemblies, allowing the pin to move axially and rotate, enabling the plastic plug to deform and align elastically for reliable insertion without adjustment, with elastic members to accommodate collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the pin is not precisely aligned with the hole, then the plastic plug cannot be pressed in smoothly or accurately, but adjusting the pin position reduces mounting efficiency
Solution Approach 1:
The pin is designed to be rotatable around its own axis and movable axially, transforming from a static component to a dynamic one. This allows the pin to automatically adjust its orientation and position during the mounting process, enabling smooth insertion even when initial alignment is not perfect, thereby resolving the contradiction between alignment precision and mounting efficiency
Solution Approach 2:
The patent changes the operational parameters of the pin by enabling rotation and axial movement. These parameter changes allow the pin to adapt to misalignment conditions through dynamic adjustment, achieving both good alignment results and high mounting efficiency without requiring manual position adjustments
2Device complexity
If the pin is fixed in position, then the structure is simple, but misalignment causes insertion failures requiring adjustments
Solution Approach 1:
By making the pin rotatable and axially movable, the invention transforms a simple but unreliable fixed structure into a slightly more complex but highly reliable dynamic structure. The added degrees of freedom enable the pin to compensate for misalignment, significantly improving insertion reliability while maintaining relatively simple overall device complexity

AI summary
A mounting mechanism includes a base, a pin movably mounted on the base, a first driving member, and a second driving member. The first driving member is connected to the pin and can drive the pin to move axially. The second driving member is connected to the pin, and can rotate the pin around its own axis, such that a plastic plug positioned on a free end of the pin can always be reliably inserted in a hole of a housing notwithstanding minor misalignments with the hole.
