One-Piece Wall Hanger With Piercing Armature for Tool-Free Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall hanging devices require tools for installation, are often multi-piece and difficult to use, and lack effective holding capacity, making them cumbersome and prone to piece loss.
Innovation Solution
A one-piece device featuring a flat plate with a 90-degree angled armature and pointed arrowhead tip for direct insertion into wallboard, allowing attachment without tools and providing a secure hold with ears gripping both sides of the board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional wall hanging devices are used, then they can provide holding capacity, but they require tools for installation and involve multiple pieces that are difficult to use
Solution Approach 1:
The patent combines multiple separate components (mounting plate, anchor, and fastening mechanism) into a single integrated one-piece device. The mounting plate includes an integrated armature with a pointed arrowhead tip for piercing wallboard and ears for gripping the inner surface, eliminating the need for separate anchors and fasteners. This merging directly resolves the contradiction by reducing device complexity while maintaining holding capacity.
2Reliability
If traditional multi-piece devices are used, then they can be assembled to provide secure attachment, but pieces are prone to be lost
Solution Approach 1:
The patent integrates the mounting plate, armature, and fastening ears into a single one-piece construction, eliminating separate components that could be lost during assembly or storage. The integrated design ensures all functional elements remain permanently attached to each other, resolving the reliability concern about lost pieces while maintaining secure attachment capability.
3Reliability
If devices requiring assembly are used, then they can provide secure attachment, but assembly is difficult and time-consuming
Solution Approach 1:
The patent creates a one-piece integrated device that requires no assembly steps. The mounting plate with integrated armature and ears is installed as a single unit, eliminating the time-consuming assembly process of traditional multi-piece devices while maintaining secure attachment through the integrated fastening mechanism.
4Ease of operation
If simple one-piece devices are used, then installation is easy, but holding capacity may be insufficient
Solution Approach 1:
The patent applies local quality by concentrating structural strength at critical locations: the pointed arrowhead tip for effective wallboard piercing, the thickened ear regions for gripping the inner surface, and the integrated armature design for distributing load. This localized reinforcement ensures sufficient holding capacity in a one-piece device without requiring multiple components.
Solution Approach 2:
The patent utilizes composite construction combining a rigid mounting plate with an integrated metal armature, creating a hybrid structure that leverages the advantages of both materials. The mounting plate provides a stable mounting surface while the metal armature provides strength for piercing and gripping, achieving high holding capacity in a single integrated piece.
