Elastic Fastening Assembly for Quick Release and Secure Joining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening devices make it difficult to quickly connect and easily disconnect workpieces, as they are often firmly fixed together, making assembly and disassembly cumbersome and inconvenient.
Innovation Solution
A fastening device comprising a head member with a stem portion and a body member, where the body member has an elastic fastening section that can engage with a workpiece, allowing for quick connection and easy disconnection by using elastic elements and abutting sections to facilitate movement and assembly within a limited range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional screws or locking elements are used to fasten workpieces, then the connection strength and stability are improved, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The fastening device employs a dynamic locking mechanism where the locking element can be moved between locked and unlocked positions. The elastic element provides continuous pressure to maintain the locking state, while the movable nature of the locking element allows for quick release when force is applied, enabling both strong connection and easy disassembly
Solution Approach 2:
The fastening device is divided into distinct functional components: a body member, a locking element, and an elastic element. This segmentation allows each component to perform its specific function independently - the body provides structure, the locking element provides the mechanical lock, and the elastic element provides the retaining force, collectively achieving both strength and ease of operation
2Stability of the object's composition
If workpieces are firmly fixed together using conventional fasteners, then the stability of the connection is improved, but the productivity for quick connection and disconnection deteriorates
Solution Approach 1:
The locking element is designed to be movable within the body member, transitioning between a locked position that provides stable connection and an unlocked position that enables quick disassembly. The elastic element maintains constant pressure to ensure stability during operation while allowing rapid release when needed
Solution Approach 2:
The elastic element automatically maintains pressure on the locking element to keep it engaged with the workpiece, providing self-servicing stability without requiring continuous external force. This automatic retaining mechanism ensures stable connection while allowing quick release when manual force is applied to overcome the elastic pressure
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 rapid assembly and disassembly of workpieces by using elastic elements that compress and restore to secure and release the connection, allowing for efficient use and storage of the fastening devices.
Implementation Method 1
the body member includes an elastic fastening section for engaging with a first workpiece
Implementation Method 2
The elastic fastening section or the elastic retaining protrusion is elastically backwardly compressible and deformable when being extended from a first side of the first workpiece through a retaining hole formed on the first workpiece, and is elastically restorable to an original shape after passing through the retaining hole

AI summary
A fastening device includes a head member and a body member. The head member has a stem portion provided with a fastening section; and the body member is movably assembled to the head member and includes an elastic fastening section for engaging with a first workpiece. To connect the first workpiece to a second workpiece, simply fasten the fastening section of the stem portion to the second workpiece. To disconnect the first workpiece from the second workpiece, simply release the fastening section from the second workpiece. With these arrangements, it is able to quickly connect and easily disconnect two workpieces to and from one another.
