Compensation Nut Assembly With Gap Control and Rotation Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial applications, there is a need for an adjustable fastener that can maintain a gap between components while securing them together, as existing fasteners often fail to prevent collapse by not accommodating varying distances effectively.
Innovation Solution
A compensation nut assembly comprising a first nut, a second nut, and a limiting member, where the first nut is rotatable relative to the second nut to adjust length, and the limiting member with blocking arms maintains the assembly within a predetermined range, allowing for secure fastening while accommodating slight variations in component distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length fastener is used, then the structure is simple, but it cannot accommodate varying distances between components
Solution Approach 1:
The fastener system transitions from a fixed-length design to a dynamically adjustable one through the first nut that can rotate relative to the second nut along the axial direction, enabling the assembly length to be modified according to varying component distances while maintaining structural simplicity
Solution Approach 2:
The fastener is divided into multiple functional segments including the first nut, second nut, and limiting member with blocking arms, allowing independent adjustment of each segment to achieve the desired overall length while maintaining ease of manufacture
2Adaptability or versatility
If an adjustable fastener is used, then varying distances can be accommodated, but the structure becomes more complex
Solution Approach 1:
The dynamic adjustment capability is achieved through the rotatable first nut that can change the axial length of the assembly, providing adaptability to varying distances while keeping the adjustment mechanism simple and integrated into the existing fastener structure
Solution Approach 2:
The fastener system allows modification of the axial length parameter through rotation of the first nut, enabling adaptation to different component distances without fundamentally changing the overall fastener design or adding significant complexity
3Adaptability or versatility
If the first nut is made rotatable to adjust length, then adaptability improves, but control over maximum extension may be lost
Solution Approach 1:
The limiting member with blocking arms provides mechanical feedback that prevents the first nut from rotating beyond a predetermined angle, giving tactile and physical feedback to the operator about the maximum extension limit while still allowing full adjustability within the safe range
Solution Approach 2:
The blocking arms are pre-positioned to counteract any rotation that would exceed the maximum extension, preventing over-rotation before it can occur by creating mechanical interference that stops the rotation at the predetermined limit

AI summary
The present disclosure provides a compensation nut assembly comprising a first nut having a limiting tab, a second nut and a limiting member connected to the second nut and comprising a first blocking arm and a second blocking arm. When the assembly is in a pre-assembled state, the first and second blocking arms retain the limiting tab therebetween in a circumferential direction. When a certain screwing force is applied to the first nut in the pre-assembled state in a first rotation direction, the first and second blocking arms are at least partially deflected by the limiting tab to allow the first nut to rotate out of the pre-assembled state. When a certain screwing force is applied to the first nut in the pre-assembled state in a second rotation direction, the first and second blocking arms restrict the first nut from rotating out of the pre-assembled state.
