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 featuring a stem portion with a fastening section and a movement portion that includes a retaining section, allowing for elastic deformation and restoration, enabling easy connection and disconnection of objects by applying force to the handling section to engage or disengage the retaining section with catching or abutting sections.
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 first position (for initial engagement) and a second position (for final locking). This dynamic capability allows the fastener to transition from an easy-to-insert state to a secure locked state, resolving the contradiction between ease of assembly and connection strength.
Solution Approach 2:
The fastener is divided into distinct functional segments: a stem portion, a movement portion, and a retaining section. This segmentation allows each part to perform its specific function independently - the movement portion handles the assembly motion while the retaining section provides the secure connection, thereby achieving both ease of operation and strong connection.
2Reliability
If a secure fastening connection is created, then the reliability of the connection is improved, but the ease of disassembly deteriorates
Solution Approach 1:
The movement portion's ability to transition between positions enables reliable connection while maintaining ease of disassembly. When force is applied to the handling section, the movement portion shifts from the first position to the second position, which triggers the retaining section to release from the catching section, allowing quick disassembly despite the secure locked state.
Solution Approach 2:
The handling section serves as an intermediary that translates user input (force applied at the handling section) into the movement portion's position change, which in turn controls the retaining section's engagement or disengagement. This intermediary mechanism provides a simple interface for both secure locking and easy release.
3Ease of operation
If a movement portion with retaining section is added, then the ease of assembly and disassembly is improved, but the device complexity increases
Solution Approach 1:
The movement portion and retaining section are merged into a single integrated component rather than separate parts. This merging reduces the overall number of components and assembly steps while still providing the desired functionality of easy assembly and disassembly, thereby minimizing the increase in device complexity.
Solution Approach 2:
The movement portion is designed with flexible characteristics, allowing it to deform elastically when force is applied. This flexibility enables the movement portion to transition between positions and engage/disengage the retaining section without requiring complex mechanical mechanisms, thus improving ease of operation while limiting complexity growth.
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 movement portion to elastically deform and restore, facilitating easy alignment and engagement with catching or abutting sections, thus simplifying the connection and disconnection process.
Implementation Method 1
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.
