Self-Threading Nut Structure for Adjustable Plate Standoff Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing objects to building structures at a distance are inconvenient due to the placement of one nut behind the plate, leading to unsatisfactory solutions for adjusting the object's distance from the structure.
Innovation Solution
A self-threading nut with a unique internal binding structure that allows for rotation relative to the plate without being releasable, featuring a hollow self-tapping thread with a space between the internal binding and the nut's surface, enabling adjustable fixing of objects to building structures at varying distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two nuts are used to fix a plate to building construction at a distance, then the object can be securely attached, but one nut must be disposed behind the plate making the fixing inconvenient
Solution Approach 1:
The patent combines two nuts into a single integrated component. The first nut engages with the bolt from one side of the plate, while the second nut is integrated into the same component and engages from the other side, eliminating the need for separate nut installations and making the fixing convenient from a single side.
Solution Approach 2:
The single nut component performs multiple functions: it provides securing engagement from both sides of the plate, enables distance adjustment through relative rotation, and eliminates the need for separate nuts. This multi-functional design simplifies the fixing operation while maintaining secure attachment.
2Adaptability or versatility
If the nut is fixed securely to the plate, then reliable attachment is achieved, but the nut cannot rotate relative to the plate for distance adjustment
Solution Approach 1:
The patent creates a dynamic system where the nut can rotate relative to the plate during the adjustment phase, allowing distance modification. After adjustment, the system can be locked into a fixed position, providing stability. This dynamic capability enables both adjustability and reliable attachment at different stages.
Solution Approach 2:
The nut is preliminarily engaged with the bolt in a loose state that allows rotation relative to the plate. This preliminary engagement enables distance adjustment before final tightening. The preliminary action of engaging without immediate full tightening allows for subsequent adjustment while maintaining attachment security.
3Adaptability or versatility
If the nut allows rotation relative to the plate for adjustment, then distance adaptability is improved, but vibration may increase
Solution Approach 1:
The patent implements a dynamic system where the nut can rotate for adjustment but includes mechanisms to limit excessive movement and dampen vibrations. The relative rotation capability provides adjustability, while the controlled dynamic interaction between the nut and plate prevents uncontrolled vibrations that would occur with completely loose connections.
