Clip Rib Structure Resists Bending During Board Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clips for mounting cementitious boards, such as fiber cement sidings, are prone to bending and lifting during installation, leading to misalignment and inefficiency due to their design, which requires multiple screws and is laborious to fix, especially for heavier boards.
Innovation Solution
A clip with a rib structure on its front surface, made from materials like stainless steel, that reduces bending by increasing the momentum of inertia, featuring multiple hook-shaped carrying means and strategically placed apertures for secure fastening, allowing for easier and quicker mounting of cementitious boards without the clips becoming misaligned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional clips are used for mounting cementitious boards, then the mounting system can hold the boards, but the clips bend and lift during installation causing misalignment and requiring multiple screws for each clip
Solution Approach 1:
The clip is divided into distinct functional segments: a base portion for mounting to the frame, hook portions for engaging the board, and a rib portion for structural reinforcement. This segmentation allows each part to be optimized independently - the base can be designed for secure attachment with minimal screws, while the rib provides the necessary stiffness to prevent bending and lifting during installation.
2Force
If clips are designed to hold heavy cementitious boards, then the clips provide sufficient holding force, but the clips become prone to bending and lifting during installation
Solution Approach 1:
The rib portion extends in a direction substantially perpendicular to the plane formed by the base and hook portions, adding a third dimensional element to the clip structure. This vertical rib acts as a stiffening element that resists bending moments and prevents the hooks from lifting during installation, while minimal intervention in the base plane maintains ease of installation.
3Reliability
If multiple screws are used to fix each clip to prevent bending, then the clip stability improves, but the installation time and labor increase significantly
Solution Approach 1:
The rib portion is pre-formed as an integral part of the clip during manufacturing, providing built-in structural reinforcement before installation. This preliminary structuring eliminates the need for additional field adjustments or multiple screws to prevent bending, as the rib already provides the necessary stiffness to maintain hook alignment during the installation process.
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 clip provides enhanced dimensional stability and reduces the tendency for hooks to lift, ensuring secure and efficient mounting of heavy cementitious boards with fewer fasteners, improving installation speed and reducing labor costs.
Implementation Method 1
A clip (100, 110, 120) suitable for mounting cementitious boards (200, 201) to a frame, in particular a wooden frame, is provided. The clip comprises a sheet (11) having a front surface (13). The sheet comprises at least one rise (40) at the front surface (13), which rise (40) extends from a first point (42) of the front surface (13), point (42) being at one side of the axis, to a second point (44) of the front surface (13), which point (44) is at the other side of the axis.
