Anti-Wobble Fir Tree Mount With Branch Flange Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fir tree mounts experience lateral movement during use, leading to potential noise and damage to attached components due to gaps between the mounting stud and distal ends of the branches, especially under severe impacts.
Innovation Solution
The anti-wobble fir tree mount incorporates a flange member on the branches to limit deflection and reduce lateral movement by providing additional support, ensuring a tighter fit within the mounting aperture without increasing insertion force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the branches are made flexible to enable insertion into the mounting aperture, then the ease of installation is improved, but the lateral support capability deteriorates under severe impacts
Solution Approach 1:
The branch is divided into two distinct portions: a first portion that is flexible and passes through the mounting aperture to engage the backside (providing insertion capability), and a second portion that remains in a flexed position within the aperture (providing lateral support). This segmentation allows each portion to fulfill its specific function optimally.
Solution Approach 2:
The solution addresses lateral support (a lateral dimension problem) by utilizing the longitudinal deflection of the branch portions. The first portion deflects longitudinally to pass through the aperture, while the second portion's longitudinal flexing position provides lateral support, effectively solving the lateral stability issue through longitudinal positioning.
2Stability of the object's composition
If the gap between the mounting stud and distal ends of the branches is reduced to prevent lateral movement, then the stability is improved, but the insertion force required increases
Solution Approach 1:
The branch portions are designed to dynamically deflect during insertion and then maintain a stable flexed position. The first portion deflects longitudinally during insertion to pass through the aperture, while the second portion dynamically flexes to a position that provides lateral support, creating a dynamic insertion process that results in static stability without requiring excessive force.
Solution Approach 2:
The solution changes the positional parameters of the branch portions through controlled deflection. The first portion changes its longitudinal position to pass through the aperture, while the second portion changes its flexed position to provide optimal lateral support within the aperture, achieving stable mounting with reduced insertion force.
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
The flange member reduces lateral movement, maintaining the position of attached components, minimizing noise and damage, and enhancing retention strength during pull-out.
Implementation Method 1
a flange member extending from the lower side, the flange member configured for contacting the upper side of the second branch during insertion of the mounting section into the mounting aperture to limit a deflection of the second branch in the direction of the body section
Implementation Method 2
a first portion of the branches may entirely pass through the mounting aperture and spring back to engage a backside of the supporting structure to retain the fir tree mount in the aperture
Implementation Method 3
a second portion of the branches remains in a flexed position within the aperture, providing for lateral support of the mounting section in the aperture
