Stud Locking Clip Structure for Wide Guidance and Smooth Sliding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stud locking tools face challenges in maintaining slideability while guiding studs over a wide range, often resulting in impaired lateral movement due to increased force between clips and limited guiding ranges.
Innovation Solution
The stud locking tool comprises a first clip with a large diameter inner cylindrical portion and a second clip with a slope guide surface, allowing for increased guiding range without compromising slideability, with engaging claws preventing the first clip from disengaging and maintaining a controlled gap between flanges to allow lateral movement of the mounting member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between flanges is reduced to guide studs over a wider range, then the guiding range is improved, but the slideability is impaired due to excessive sandwiching force
Solution Approach 1:
The patent applies parameter changes by introducing a controlled gap between the first and second flanges. This gap parameter allows the mounting member to maintain lateral slideability while the slope guide surface provides extended stud guidance. The gap prevents excessive sandwiching force that would otherwise eliminate slideability, thus resolving the contradiction between guiding range and ease of operation.
2Reliability
If the clips are tightened to secure the mounting member, then the reliability of attachment is improved, but the lateral movement capability is reduced
Solution Approach 1:
The patent applies dynamics by designing the mounting member with movable mounting holes that can shift laterally within a predetermined range. This dynamic capability allows the mounting holes to self-align with studs during installation while maintaining secure attachment once positioned. The engaging claws and slope guide surface work together to provide both movement capability and attachment reliability.
3Adaptability or versatility
If the inner cylindrical portion is made larger to improve stud reception, then the stud receiving capability is improved, but the engagement with the outer cylinder is compromised
Solution Approach 1:
The patent applies the intermediary principle by introducing a gap between the first and second flanges as a mediating space. This gap allows the inner cylindrical portion to be larger for improved stud reception while preventing direct excessive contact between the clips that would compromise engagement strength. The gap acts as a buffer that maintains both stud receiving capability and engagement integrity.

AI summary
[Problem] With a stud locking tool for attaching a mounting member to a member to be mounted on which a stud is erected, to provide a stud locking tool which has a wide range for guiding a stud and does not experience deteriorated slideability. [Solution] A stud locking tool 1 is equipped with a first clip 10 and a second clip 30 for sandwiching a mounting member 51; the mounting member 51 is mounted in a member to be mounted 61 by locking the stud 70. The first clip 10 has a hollow inner cylindrical portion inserted into a mounting hole 53 of the mounting member, a first flange 11 provided at one end of the inner cylinder portion, and a locking claw 25 formed inside the inner cylindrical portion and engaged with a thread of the stud. The second clip has a hollow outer cylinder portion 35 that accommodates the inner cylinder portion of the first clip, a second flange 31 provided at one end of the outer cylinder portion, an engagement claw 38 provided inside the outer cylinder portion and engaged with the first clip, and an inclined surface 42 adjacent to the outer cylinder portion and having a guiding surface for guiding the end portion of the stud.
