Quick-Install Nut Assembly for Stable Bolt Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nuts require significant time and effort for installation, are difficult to operate in confined spaces, and often fail to align properly with bolts due to tilting or shaking, leading to inefficient and unstable fastening.
Innovation Solution
A quick install nut design featuring a threaded member with staggered holes and a driving member that allows for easy alignment and secure fastening by tilting and rotating the nut to engage with the bolt, using a closed ring or closing member to stabilize the bolt during threading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional nut is used for fastening, then the nut can be securely fastened to the bolt, but the installation time is long and installation efficiency is reduced
Solution Approach 1:
The nut body is divided into two separate half-shells that can be assembled around the bolt from different directions (top and bottom), eliminating the need for the nut to be threaded onto the bolt from one end. This segmentation allows simultaneous insertion of both halves onto the bolt, dramatically reducing installation time while maintaining secure fastening capability.
2Ease of operation
If a conventional nut is used in a narrow space, then the nut can provide fastening function, but the narrow space adversely affects rotation and operation of the nut with long stroke
Solution Approach 1:
By dividing the nut into two half-shells that open toward each other, the invention eliminates the need for rotational movement during installation. The half-shells can be directly inserted onto the bolt from opposite directions and secured with locking members, making the operation feasible in narrow spaces where rotation is restricted.
Solution Approach 2:
Instead of threading the nut onto the bolt in the conventional manner (requiring rotation along the bolt axis), the invention inverts the approach by having the bolt pass through openings in both half-shells simultaneously. The fastening is achieved by securing the half-shells together laterally rather than by axial threading, enabling operation in confined spaces.
3Reliability
If a conventional nut is used, then the nut can be fastened to the bolt, but the nut may tilt or shake during installation making alignment difficult and requiring multiple tightening operations
Solution Approach 1:
The half-shells are pre-configured with opening directions that face each other, and the locking members are pre-positioned to engage with corresponding locking grooves. This preliminary arrangement ensures that when the half-shells are assembled onto the bolt, they automatically align in the correct orientation, preventing tilting and shaking during installation and eliminating the need for multiple tightening operations.

AI summary
A quick install nut includes a threaded member and a driving member rotatably connected to the threaded member. The nut is tilted and mounted to a bolt and two segments of threads staggered relatively inside the threaded member are engaged with the bolt after the nut being returned. By the driving member rotating the threaded member, a closed ring in the driving member allows the bolt to be closed inside the nut, forces the bolt engaged with the threaded member, and drives the nut to be fastened tightly to the bolt. The closed ring is moved with the driving member. The threaded member can have only single segment of threads so that the bolt enters the nut horizontally. Thereby the bolt keeps engaged with the nut during mounting and fastening of the nut. Therefore, quick and firm fastening is achieved.
