Wall Hook Anchor With Wedging Nail for Low-Damage Drywall Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall mounting systems require multiple steps and tools, such as drills, and cause significant damage to walls, especially when removing anchors, and are limited in their ability to support large loads without damaging the drywall.
Innovation Solution
A wall anchor system featuring a wide circular platform with a guide hole and deformable material, using a specially designed nail with a large head and flattened upper shank that wedges into the platform, allowing for easy installation with a hammer and minimal wall damage, as the nail becomes lodged tightly, supporting large loads without loosening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional drywall anchors are used to mount large fixtures, then the fixture can be securely attached to the wall, but the installation requires multiple steps including drilling a large hole, hammering in the anchor, and screwing the fixture into the anchor
Solution Approach 1:
The patent combines the mounting hole creation and fixture attachment into a single operation. The circular mounting surface with central hole allows the nail to simultaneously create the mounting hole and secure the fixture in one step, eliminating the separate steps of drilling, inserting anchor, and screwing the fixture.
Solution Approach 2:
The patent extracts the drilling operation entirely from the installation process. By using a nail driven through a pre-formed circular mounting surface, the system eliminates the need for power drills and complex drilling operations, reducing installation to a simple hammering action.
2Strength
If traditional drywall anchors are used to support large loads, then the fixture can carry heavy weights, but the anchors cause significant damage to the wall and leave large holes when removed
Solution Approach 1:
The patent concentrates the load-bearing function to a specific local structure: the circular mounting surface with its central hole and the nail passing through it. This localized design allows the fixture to carry large loads (up to 80 lbs as stated in the summary) while the damage is confined to a small circular area rather than a large hole.
Solution Approach 2:
Instead of creating a large hole to insert an anchor and then attaching the fixture, the patent inverts the approach by using a small circular mounting surface that requires only a small hole for the nail. The load capacity is achieved not through the size of the hole but through the mechanical interlocking of the nail with the circular mounting structure.
3Object-affected harmful factors
If no-drill hooks using adhesives are used to avoid wall damage, then the wall damage is minimized, but the weight capacity is extremely limited
Solution Approach 1:
The patent introduces a circular mounting surface with a central hole as an intermediary structure between the nail and the fixture. This intermediate structure allows the simple act of hammering a nail to create a mounting point that can support large loads, bridging the gap between simple installation and high weight capacity.
4Reliability
If a specially designed nail with flattened upper shank is used to wedge into the platform, then the fixture becomes securely anchored and cannot easily loosen, but the nail becomes difficult to remove
Solution Approach 1:
The patent employs a dynamic installation and removal process. During installation, the nail is driven in and the flattened portion wedges into the circular mounting surface, creating a secure mechanical lock. During removal, a downward force is applied to the fixture, which pushes the nail through the circular surface and out the other side, allowing easy extraction. The system transitions from a locked state during use to an easy removal state during uninstallation.
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
Enables one-step installation of large fixtures without drilling, minimal wall damage, and secure anchoring capable of handling repeated loads up to 80 lbs, with easy removal by knocking the fixture base and pulling out the nail with pliers.
Implementation Method 1
the upper nail shank will deform the guide hole and pocket surrounding the guide hole, and become lodged very tightly into the fixture through wedging forces
Implementation Method 2
a specially designed nail, manufactured from a traditional wire round nail, featuring a large wide head, a pointed distal end

AI summary
A hook mounting system of a unibody structure with three platforms that face an angled hole. The hook system includes nails adapted to be particularly suitable for mounting the hook and platform deformable inserts to receive the nails. The system is adapted for a rod hanging assembly. The system includes a nail having a non-circular shank portion and a knurled head.
