Nut Pincher Mount Structure for Screw Misalignment Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixing mechanisms fail to properly secure components with screws when significant misalignment occurs between the through-hole of a fixture and the threaded hole of a nut due to design errors or tolerances.
Innovation Solution
A fixing mechanism featuring deformable pinchers that pinch a nut, allowing it to move within a housing recess to align with the through-hole, and protrusions that prevent the nut from dislodging, ensuring secure screw-fastening despite misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screw-fastening is used with rigid fixtures, then proper alignment is achieved under ideal conditions, but screw-fastening fails when large misalignment occurs between through-hole and threaded hole
Solution Approach 1:
The nut is designed with deformable pinchers that can dynamically adjust their position to accommodate misalignment between the through-hole and threaded hole. The pinchers are configured to be elastically deformable, allowing the nut to adapt its shape and position during the screw-fastening process, thereby maintaining reliable fastening even when significant misalignment occurs.
Solution Approach 2:
The nut's physical parameters are changed by making the pinchers deformable rather than rigid. This allows the nut to change its effective position and orientation by deforming the pincher elements, enabling it to compensate for misalignment and achieve proper screw-fastening under varying alignment conditions.
2Adaptability or versatility
If deformable pinchers are used to accommodate misalignment, then adaptability to misalignment is improved, but device complexity increases
Solution Approach 1:
The nut is segmented into multiple functional parts: a body portion and multiple pinchers that can deform independently. This segmentation allows each pincher to adjust separately to accommodate misalignment, providing adaptability while keeping the overall structure manageable through modular design.
Solution Approach 2:
The pinchers are designed as flexible, elastically deformable elements that can bend and adjust their position. This flexibility is achieved through appropriate material selection and geometric design, allowing the pinchers to accommodate misalignment without requiring complex mechanical adjustment mechanisms.

Function Achieved in This Case
Enables proper screw-fastening even with large misalignments by aligning the through-hole and threaded hole, preventing nut displacement, and maintaining secure attachment.
Implementation Method 1
at least one pair of pinchers configured to pinch the nut, in which the paired pinchers are disposed to oppose each other and are deformable in a direction opposing each other
