Pivotable Jaw-Type Wall Anchor for Friable Material Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall anchors are difficult to install, provide insufficient support strength, cause significant damage to walls, and are not suitable for minor position adjustments, especially in friable materials like drywall, and lack resistance to perpendicular loading.
Innovation Solution
An anchor assembly with pivotable components featuring curved wall penetrating retainers that form a jaw-type arrangement upon installation, allowing for easy insertion and high support strength without requiring tools, and enabling minor adjustments and resistance to cantilever loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional nails and screws are used for mounting, then the mounting solution is simple, but the support strength is insufficient in friable wall materials
Solution Approach 1:
The anchor assembly employs pivotable components that transition from a compressed pre-installation state to an expanded post-installation state. The first and second anchor components pivot relative to each other, causing the retainers to expand and form interlocking jaw-type arrangement within the wall material, thereby achieving high support strength without complex installation tools.
2Strength
If anchors with large wall penetration are used, then the support strength is improved, but the damage to wallboard increases and leaves large holes
Solution Approach 1:
The anchor assembly divides the wall penetration function across multiple segmented retainers (first retainer and second retainer) that work together in a jaw-type arrangement. This segmentation allows the load to be distributed across several smaller penetration points rather than requiring a single large penetration, thereby maintaining support strength while minimizing wallboard damage.
3Ease of operation
If traditional anchors are installed, then the installation process is straightforward, but repositioning is impractical after initial insertion
Solution Approach 1:
The pivotable connection between anchor components creates a dynamic installation system. During installation, the components can pivot to accommodate slight position adjustments. The compressed pre-installation configuration allows the retainers to be inserted at slightly varied angles and positions, and they will still form the proper jaw-type arrangement once installed, enabling minor repositioning without requiring complete removal.
4Adaptability or versatility
If simple hook anchors are used, then the device complexity is reduced, but the ability to secure various objects securely is limited
Solution Approach 1:
The anchor assembly provides universal mounting capability through its jaw-type retainer arrangement that can securely hold various object types including shelves, towel bars, and coat racks. The interlocking first and second retainers create a versatile gripping mechanism that adapts to different object geometries and loading conditions, achieving multi-functionality without excessive structural complexity.

AI summary
An anchor assembly for anchoring an object on a wall includes a first anchor component and second anchor component, each anchor component pivotable relative to the assembly and having a back side and a front side, and each anchor component having at least one curved wall penetrating retainer extending therefrom. The anchor assembly has an install orientation in the wall in which the wall penetrating retainer of each anchor component is inserted within the wall for a jaw-type grip of the wall.
