Fastener Structure for Quick Coupling and Easy Unfastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastener structures require complex and difficult unfastening processes, making it hard to separate coupled objects.
Innovation Solution
A fastener structure comprising a head portion, rod member, and fitting member, where the head portion drives the engaging portion of the rod member to penetrate an object for coupling and is reversed for easy unfastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fasten two objects together, then the coupling strength and firmness are improved, but the ease of unfastening deteriorates
Solution Approach 1:
The fastening system is divided into separate components: a fastener body with a head portion and a rod member. The rod member can be inserted through the head portion to create a modular assembly that maintains strong coupling while allowing easy disassembly by simply removing the rod member, eliminating the need to unscrew threads.
Solution Approach 2:
Instead of using threaded screws that require rotational unscrewing, the invention inverts the approach by using a straight rod member that is inserted linearly through the fastener body. The unfastening process is also inverted - rather than rotating to loosen, the rod member is simply pulled out in a linear motion, making unfastening as easy as the fastening process.
2Stability of the object's composition
If screws are used to fasten two objects together, then the objects are firmly coupled and cannot be easily separated, but the complexity of the fastening process increases
Solution Approach 1:
The fastening system separates the coupling function into distinct elements: the fastener body that engages with the object and the rod member that secures the assembly. This segmentation allows the rod member to be a simple insertable component rather than a complex threaded fastener, reducing overall system complexity while maintaining coupling stability.
Solution Approach 2:
The invention simplifies the fastening process by inverting the traditional screw mechanism. Instead of requiring threaded engagement and rotational motion, the rod member is inserted linearly through the head portion, creating a firm coupling through simple geometric interference rather than threaded friction, thereby reducing process complexity.
3Reliability
If traditional fastening methods are used, then reliable coupling is achieved, but the time required for coupling and unfastening increases
Solution Approach 1:
The rod member is pre-configured with engagement features that align with corresponding features in the head portion. This preliminary configuration ensures that when the rod member is inserted, it automatically engages with the correct positioning, providing reliable coupling in a single motion without requiring alignment adjustments or multiple steps, thus reducing time while maintaining reliability.
Solution Approach 2:
The invention inverts the time-consuming threaded engagement process into a rapid linear insertion process. The rod member is designed to slide through the head portion in a straight line, eliminating the time required for rotational screwing. The reliability is maintained through precise geometric fitting rather than threaded friction, achieving both speed and reliability simultaneously.

AI summary
A fastener structure includes a head portion, rod member and fitting member. The head portion has a lateral holding portion and vertical receiving portion. The rod member has a lateral attaching portion and engaging member. The rod member is penetratingly disposed at the receiving portion to allow the attaching portion to correspond in position to the holding portion. The fitting member is penetratingly disposed at the attaching portion and the holding portion to fit the head portion and the rod member together. To couple two objects together, the head portion drives an engaging portion of the rod member, such that the engaging portion penetrates one object before being fastened to the other object. To unfasten the objects, the head portion is moved reversely to remove the engaging portion from the other object, effecting separation of the objects, so as to achieve quick coupling and easy unfastening.
