Elastic Fastener Structure for Quick Repeatable Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastener structures make it difficult to quickly and repeatedly connect and disconnect objects, as they often require complex assembly processes and are not easily demountable.
Innovation Solution
A fastener structure with a stem portion and a movement portion, featuring a retaining section that can be elastically deformed and restored, allowing for easy connection and disconnection by rotating the fastener between two objects using a flexible connecting section and elastic elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to connect objects, then the connection strength is improved, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The fastener incorporates a movement portion that can dynamically change position between a retained state (for strong connection) and a released state (for easy disassembly). The movement portion includes a retaining section that can engage with catching sections on objects to provide secure connection, and when released, allows quick disassembly without tools.
Solution Approach 2:
The fastener is divided into distinct functional sections: a stem portion with fastening section for connection, a movement portion with retaining section for engagement, and a connecting section with recess for elastic deformation. This segmentation allows each part to perform its specific function optimally while working together to resolve the contradiction between strong connection and easy disassembly.
2Stability of the object's composition
If a rigid fastening structure is used, then the stability of connection is improved, but the ease of manufacture and assembly deteriorates
Solution Approach 1:
The connecting section is designed with specific elastic properties allowing it to deform within a controlled range. The recess in the connecting section enables the movement portion to be elastically deformable, allowing it to compress and expand during assembly and disassembly while maintaining stable connection when engaged.
Solution Approach 2:
The elastic deformation capability of the connecting section allows the fastener to self-adjust during assembly. The movement portion can be compressed to disengage from catching sections and automatically returns to its original position to engage again, providing self-service functionality that simplifies assembly and disassembly operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and repeatable assembly and disassembly of objects by allowing the retaining section to expand outward for alignment and then return to its initial position, facilitating easy engagement and disengagement with catching sections on objects.
Implementation Method 1
a first elastic element, which has an end pressed against the movement portion and another end against the head section, such that the movement portion is allowed for elastic displacement
Implementation Method 2
a recess or spacing section is formed between the head section and the movement portion to provide a connecting section, and the recess serves as a space allowing the movement portion to be elastically deformable and restorable

AI summary
A fastener structure includes a fastener having a stem portion and at least one movement portion. The stem portion has a fastening section. The movement portion is formed on the stem portion and has a retaining section. With these arrangements, the retaining section of the movement portion can be detachably assembled to a first object and the fastening section can be then detachably assembled or fastened to a second object. In this way, at least two objects can be connected to and disconnected from one another in a quick and repeatable manner.
