Integral Wing Nut Anchor Structure for Easier Thermal Concrete Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermal concrete wing nut anchors are difficult to fabricate conveniently and cost-effectively due to the complex process of combining metal sheet plates by soldering, resulting in an uneven appearance with protruding stop flange and driving head.
Innovation Solution
A wing nut anchor with an integral metal sheet plate structure, featuring internal and external threads, where the stop flange and driving head are recessed within the wing nut, allowing for easier fabrication and a smooth appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If two metal sheet plates are combined by soldering to form the wing nut assembly, then the structural strength is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent merges two separate metal sheet plates into a single integrated wing nut assembly through integral forming. The wing nut assembly comprises a single metal sheet plate with a first ear and a second ear formed integrally, eliminating the need for soldering operations while maintaining structural strength. This is achieved by designing the single plate to fold or form both ears and the connecting portion in one piece, thus resolving the contradiction between strength and manufacturing complexity.
2Stability of the object's composition
If two metal sheet plates are combined by soldering to form the wing nut assembly, then the structural integrity is improved, but the fabrication cost increases
Solution Approach 1:
The patent combines multiple components into a single integral structure that can be formed from one metal sheet plate through pressing and folding operations. The wing nut assembly with its first ear, second ear, and connecting portion is created as a single piece, eliminating soldering costs and simplifying fabrication while maintaining structural integrity through the continuous material structure.
3Ease of operation
If the stop flange and driving head protrude from the wing nut assembly, then the functional requirements are met, but the appearance becomes uneven
Solution Approach 1:
The patent applies the nesting principle by placing the stop flange and driving head within a recessed portion of the wing nut assembly. The recessed portion is formed in the single metal sheet plate to create a cavity that receives and conceals the protruding elements, allowing the functional components to be nested within the overall structure. This achieves a flush, even appearance while maintaining the functional integrity of the stop flange and driving head.

AI summary
A thermal concrete wing nut anchor includes a screw having an external thread, and a wing nut mounted on the screw. The screw has a first end provided with an enlarged stop flange, and a second end provided with a drilling tip. The stop flange is provided with a driving head. The wing nut is made of a metal sheet plate which is formed integrally by pressing. The wing nut has a middle provided with a first ear and at least one second ear. The wing nut has an internal thread extending through the first ear and the at least one second ear. The external thread of the screw is screwed through the internal thread of the wing nut.
