Snap-On Spin Nut for One-Handed Threaded Rod Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening systems for securing construction components like pipes, cables, and struts are time-consuming and cumbersome, requiring two hands and manual alignment, especially in inaccessible areas, and are difficult to install without tools.
Innovation Solution
A spin nut with a snap retainer and sectioned threaded nut sections that can be easily snapped onto a threaded rod, allowing for one-handed installation and automatic alignment, reducing the need for manual threading and tool use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional nuts and threaded rods are used for fastening construction components, then the connection strength is sufficient, but the installation time and complexity increase significantly
Solution Approach 1:
The fastening system is divided into modular components: a U-shaped bracket with pre-formed channels, sectioned threaded nut sections that can be independently manipulated, and a snap retainer mechanism. This segmentation allows the installer to work with smaller, more manageable parts rather than a single large nut, reducing installation complexity and time while maintaining connection strength.
Solution Approach 2:
The threaded rod is pre-threaded with external threads before installation, and the U-shaped bracket channels are pre-formed with specific geometries. The sectioned nut sections are designed to engage these pre-prepared features, eliminating the need for on-site threading operations and reducing installation time while ensuring proper connection strength.
2Force
If two conventional nuts are used on either side of the strut to clamp the rod, then the clamping force is adequate, but the operation requires two hands and is tedious
Solution Approach 1:
Multiple functional elements are merged into a single integrated fastening assembly: the sectioned nut sections, snap retainer, and engagement mechanism work together as one unit. This allows the installer to achieve adequate clamping force while operating with a single hand, eliminating the need to separately position and tighten multiple independent nuts.
Solution Approach 2:
The snap retainer mechanism automatically engages and secures the sectioned nut sections to the threaded rod and U-shaped bracket without requiring manual positioning or adjustment by the installer. The system self-adjusts to achieve proper clamping force, reducing the physical effort and dexterity required during installation.
3Adaptability or versatility
If fasteners are installed in difficult or inaccessible locations, then the fastening coverage is complete, but the installation becomes cumbersome and may require tools
Solution Approach 1:
The fastening system is designed to operate in multiple spatial orientations and configurations. The U-shaped bracket with its channels and the sectioned nut sections can accommodate various rod positions and angles, enabling complete fastening coverage in difficult locations while maintaining ease of installation through the simplified snap-together mechanism that doesn't require complex tool operations.
4Productivity
If sectioned threaded nut sections are used with a snap retainer, then the installation speed increases, but the device complexity increases
Solution Approach 1:
The nut is divided into sectioned threaded nut sections that can be independently manufactured and assembled. This segmentation enables faster installation through the snap retainer mechanism while keeping each individual section relatively simple in structure, balancing productivity improvement with manageable device complexity.

AI summary
A spin nut is operable to attach to a threaded fastener such as a rod. The spin nut includes a threaded nut having a shoulder for supporting a bracket, and a snap retainer detachably coupled to the threaded nut operable to spin onto any position on the threaded rod. At least one wing is formed on the snap retainer operable to attach to a bracket having a hole and spin to adjust to a position on the threaded rod. The snap retainer is detachably couple the plurality of sectioned threaded nut sections operable to spring open on a side opposite the band to allow the threaded rod to pass through.
