Pivoting Wall Anchor Assembly for Strong Drywall Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall anchors are difficult to install, provide insufficient support strength, and cause significant damage to drywall, making them impractical for securing a wide variety of objects, especially in drywall or friable wallboards, and do not allow for minor position adjustments without tools or stud location reference.
Innovation Solution
A dual-component anchor assembly with pivotable retainers forming a jaw-type configuration, allowing for staged installation without tools and minimal wall penetration, enabling secure mounting of objects with high support strength and allowing for minor position adjustments, and designed for use in drywall and other friable materials without requiring stud location or wire/pipe consideration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional nails and screws are used to hang objects on drywall, then installation is simple, but support strength is insufficient and wall damage is significant
Solution Approach 1:
The anchor assembly is divided into multiple components including a base component, a retainer component, and a cam component that work together to distribute loading and achieve both high support strength and minimal wall damage
Solution Approach 2:
The retainer component is designed to be movable relative to the base component, transitioning from an insertion position to an engaged position where it forms a jaw-type arrangement with the cam component, dynamically adapting to loading conditions
2Strength
If traditional anchors with large wall penetration are used, then support strength is high, but wall damage is significant and position adjustments are difficult
Solution Approach 1:
The pivotable retainer component allows the anchor to be adjusted to different positions before final engagement, enabling minor position adjustments without tools while maintaining high support strength through the jaw-type gripping mechanism
Solution Approach 2:
The anchor design changes the penetration depth parameter to be minimal compared to traditional anchors, while compensating for strength through the mechanical advantage of the cam and retainer engagement mechanism
3Strength
If anchors requiring hammer installation are used, then support strength is high, but ease of installation deteriorates
Solution Approach 1:
The anchor assembly is designed to be self-installing through a two-stage process where the retainer component is first inserted manually and then engaged with the cam component, eliminating the need for external tools like hammers while maintaining high support strength
Solution Approach 2:
The movable retainer component transitions from an insertion position to an engaged position through manual manipulation, providing a tool-free installation process that achieves strong wall anchoring

AI summary
An anchor assembly for hanging an object on a wall includes a first anchor component and a second anchor component. The second anchor component is pivotably associated with the first anchor component for movement between an anchoring orientation and a non-anchoring orientation to enable staged installation of the anchor assembly into a wall. At least one wall penetrating retainer extends from each of the first and second anchor components. When the second anchor component is in the anchoring orientation a curved configuration of the wall penetrating extent of the retainer of the second anchor component opposes a curved configuration of the wall penetrating extent of the retainer of the first anchor component to form a jaw-type arrangement.
