Twist-Break Fastener Structure for Stable Anti-Loosening Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastener structures often result in unstable coupling of objects due to their structural design, leading to potential loosening during use.
Innovation Solution
A fastener structure comprising a head, a fastening portion, and a twist break portion, where the twist break portion is twisted and broken upon fastening to ensure a stable connection, allowing for adjustable twisting force and various material and manufacturing options, including lathing, forging, or injection molding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional fixture structure is used for coupling objects, then the coupling can be achieved, but the combined object becomes unstable and may become loose
Solution Approach 1:
The fastener is divided into distinct functional segments: a head portion, a fastening portion with threading, and a twist break portion. This segmentation allows each part to perform its specific function - the threading provides secure attachment while the twist break portion acts as a mechanical stop to prevent over-tightening and maintains stability
Solution Approach 2:
The twist break portion is pre-configured in a twisted state before use. When the fastener is installed, this pre-twisted portion breaks at a predetermined point, automatically providing the mechanical stop function without requiring additional components or adjustment steps
2Reliability
If the twist break portion is twisted and broken upon fastening, then a stable connection is ensured, but the fastening process becomes more complex
Solution Approach 1:
The breaking mechanism is merged directly into the fastener body as an integral twist break portion. This eliminates the need for separate breaking devices or additional components, reducing overall system complexity while maintaining the stable connection benefit
Solution Approach 2:
The twist break portion is designed to self-activate during the fastening process. As the fastener is tightened, the pre-twisted portion automatically breaks at its predetermined weak point, providing the mechanical stop function without requiring external intervention or complex control mechanisms

AI summary
A fastener structure includes a head, a fastening portion and a twist break portion. The twist break portion is fastened at an object by the fastening portion, or is fastened at another object through the object by the fastening portion. Once the fastening portion is fastened, the twist break portion is twisted and broken. Thus, the fastener structure of the present disclosure is capable of providing a required object with a stable combining effect.
