Sheet-Metal Trapezoidal Nut Structure for Vibration Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nuts lack the ability to withstand unscrewing due to vibrations, lack a smooth surface for securing ropes or cables, and are complex to manufacture and assemble, often made from expensive materials.
Innovation Solution
A trapezoidal nut design featuring a threaded hole, spikes, and a smooth surface hole, allowing secure attachment and prevention of spontaneous unscrewing, made from sheet metal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional nuts are used, then they can be fastened and held in position, but they have weak ability to withstand unscrewing during exploitation due to vibration
Solution Approach 1:
The nut is divided into two functional parts: a threaded portion for fastening and a smooth surface portion with attachment means. This segmentation allows each part to specialize in its function, with the smooth surface portion specifically designed to prevent unscrewing during vibration through positive mechanical engagement features
Solution Approach 2:
The nut features an asymmetric design with a threaded portion on one side and a smooth surface portion with attachment means on the other side. This asymmetry allows the nut to engage with the mounting surface through the threaded portion while the smooth surface portion provides vibration resistance through positive mechanical engagement, preventing spontaneous unscrewing during exploitation
2Adaptability or versatility
If conventional nuts are used, then they provide fastening capability, but they lack a smooth surface hole for pushing and tying rope-cable products
Solution Approach 1:
The nut is designed with multi-functionality, combining fastening capability through the threaded portion with attachment capability through the smooth surface portion. The smooth surface portion can accommodate various attachment methods including ropes, cables, and other objects, making the nut universally applicable for both fastening and securing purposes
3Ease of manufacture
If conventional nuts are used, then they provide fastening function, but they are too complex to manufacture and assemble and made from expensive metal
Solution Approach 1:
The threaded portion and smooth surface portion are merged into a single integrated nut structure. This merging eliminates the need for separate manufacturing and assembly of multiple components, simplifying production while maintaining the reliability of both fastening and attachment functions through the unified design

AI summary
The present invention relates to a trapezoidal nut made of sheet metal, proportionally folded under a bend angle to form two parts, with a threaded hole and spikes on one side and a smooth surface hole on another side. The purpose of the invention is to add the ability to attach any object to a nut without compromising its integrity and general purpose, and reliably use a nut without spontaneous unscrewing and detachment from the mounting plane. The goal is achieved by the fact that the trapezoidal nut is fastened with a use of a threaded hole and fixed to be in a static position, with the help of spikes. The smooth surface hole can be used for any purpose at the discretion of the user. The result of the work of the trapezoidal nut is a reliable fixation (without unwanted unscrewing) on a flat surface and the ability to tie or hock anything or any means attached to it.
