Wall Holder Mount With Self-Drilling Drywall Anchor Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall mountable holders struggle with installation in friable substrates like drywall, often resulting in poor holding strength due to misalignment, deformation, and increased stress, which can lead to failure during installation.
Innovation Solution
A substrate-mountable holder system featuring a first portion with a lobe and pad for alignment and a second portion with detents for secure engagement, along with a self-drilling drywall anchor, to ensure proper orientation and increased pullout resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a holder with an integrated screw is installed by rotating the entire holder, then the fastener can be driven into the mounting substrate, but the fastener may not be oriented properly requiring partial turns that weaken holding strength or embed non-threaded portions into the substrate
Solution Approach 1:
The holder is divided into a base portion and a mounting portion that can rotate independently. The base portion remains stationary while the mounting portion rotates to orient the fastener correctly, preventing weakening from backward rotation and avoiding substrate damage from non-threaded portion embedding.
Solution Approach 2:
The fastener is pre-installed in the mounting portion before the holder is attached to the substrate. This preliminary action ensures the fastener is already oriented correctly and secured, eliminating the need for post-installation orientation adjustments that compromise holding strength.
2Adaptability or versatility
If holders are designed for use in rigid substrates like exposed studs, then installation may be simpler, but they perform poorly in friable substrates like drywall
Solution Approach 1:
A specialized anchor designed for friable substrates serves as an intermediary between the holder and the drywall. This anchor provides a secure mounting point in soft substrates, enabling the holder to achieve reliable holding strength comparable to rigid substrate installations.
Solution Approach 2:
The mounting system changes its parameters by using different fastening mechanisms optimized for friable substrates. The anchor expands or engages with the drywall in a controlled manner to create sufficient holding strength, adapting the installation approach to match the substrate characteristics.
3Reliability
If pre-drilling into the stud is performed to embed threaded portions, then holding strength increases, but additional planning, tools and time are required
Solution Approach 1:
The anchor is designed to create its own installation path and secure itself within the friable substrate without requiring pre-drilling. The self-service nature of the anchor installation eliminates the need for additional planning, tools, and time while maintaining high holding strength.
Solution Approach 2:
The installation process skips the pre-drilling step entirely by using an anchor that can be directly driven or pressed into the friable substrate. This rushing through of the installation process reduces time and complexity while achieving the same holding strength outcome.
4Productivity
If screws are driven without careful pilot hole positioning, then installation is faster, but stripping of the drywall occurs reducing holding strength
Solution Approach 1:
The anchor is designed to self-align and self-secure within the substrate without requiring careful pre-positioning of pilot holes. The self-service mechanism prevents drywall stripping while maintaining installation speed, as the anchor creates its own optimal installation path.
Solution Approach 2:
The anchor design incorporates features that cushion and distribute installation forces evenly across the drywall surface. This beforehand cushioning prevents localized stress concentration that would cause stripping, allowing fast installation without compromising holding strength.
