Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional quick install nuts face challenges in production efficiency and material costs due to design limitations, such as being restricted to metal materials and limited space for thread engagement, which hinders smooth movement and application, especially in narrow spaces.
Innovation Solution
A quick install nut design featuring a half-shell threaded portion with a first slot and second slot arranged in a staggered manner, forming radial openings and relief spaces, allowing for molding production and increased tilted angle flexibility, enabling efficient assembly and fastening on various threaded fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the threaded hole is completely enclosed in the main body with a closed through hole design, then the nut structure is compact and complete, but the internal threads cannot be formed integrally by draft molding, limiting production to expensive metal forming methods
Solution Approach 1:
The nut body is divided into two separate half-shells that are molded independently and then assembled together. This segmentation allows each half-shell to be formed with draft angles for efficient molding, while the assembled complete nut provides the necessary structural integrity and threaded hole functionality.
2Adaptability or versatility
If the closed through hole design is used, then the nut structure is complete, but the space for relief of the threaded rod is limited and the tilt angle is restricted
Solution Approach 1:
Dividing the nut into two open half-shells creates internal space for relief of the threaded rod, allowing greater tilt angles during installation while maintaining structural completeness when assembled.
Solution Approach 2:
The open half-shell design adds dimensional space within the nut structure, allowing the threaded rod to be relieved and tilted at larger angles without interference from a closed through hole structure.
3Volume of moving object
If the nut is designed to be slender, then the nut occupies less space, but the closed through hole design cannot provide sufficient space for relief of the threaded rod
Solution Approach 1:
The open half-shell structure provides internal relief space within a compact external dimensions, allowing the nut to remain slender while accommodating the threaded rod relief requirements.
4Productivity
If conventional metal forming methods are used to produce the threaded hole and internal threads, then the structural integrity is ensured, but the production efficiency is restricted and material costs are high
Solution Approach 1:
Dividing the nut into two open half-shells enables efficient plastic molding production, significantly improving productivity and reducing material costs compared to metal forming methods.
Solution Approach 2:
The invention replaces expensive metal forming methods with plastic molding technology, substituting a more efficient manufacturing process that allows integral formation of threads and better production scalability.

AI summary
A quick install nut is provided. The nut includes an entrance end, an exit end, a first threaded portion corresponding to the entrance end, a second threaded portion corresponding to the exit end and connected with the first threaded portion. The first threaded portion includes a first slot, a segment of first internal thread formed in the first slot, and a first relief space communicating with the first slot radially. The second threaded portion includes a second slot, a segment of second internal thread formed in the second slot, and a second relief space communicating with the second slot radially. The first and the second slots are disposed on a central axis in a staggered manner. A compression wall is formed on the first threaded portion. After being tilted, the nut is placed and moved along a threaded fastener and returned to achieve fast and firm fastening.
