Fastener Structure With Intermediate Member for Repeatable Quick Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening methods often result in unstable connections between objects, making it difficult to achieve repeatable and quick connection and disconnection.
Innovation Solution
A fastener structure comprising a head portion and a body portion with a connecting section that uses an intermediate member with a material retaining or expanding section to securely connect and disconnect from an object, allowing for repeated use by applying external forces to deform and assemble the components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to directly lock objects together, then fixed connection is achieved, but the connection becomes non-easily-separable and may become unstably movable
Solution Approach 1:
The fastening system is divided into three separate components: a fastener (with head and body portions), an intermediate member, and the object to be fastened. This segmentation allows the fastener to be repeatedly inserted and removed from the intermediate member while maintaining a stable connection when assembled, resolving the contradiction between strong fixed connection and ease of separation.
Solution Approach 2:
An intermediate member is introduced as a mediator between the fastener and the object. The intermediate member includes a retaining section that can be deformed to connect to the object, and a connecting section that interfaces with the fastener. This intermediary component enables repeatable connection and disconnection while maintaining stable fastening when assembled.
2Productivity
If conventional fastening methods are used, then connection is achieved, but repeatable and quick connection and disconnection cannot be enabled
Solution Approach 1:
The body portion is designed to be movably connected to the head portion, allowing dynamic insertion and removal. The connecting section can be assembled to and disassembled from the intermediate member quickly, while the mating stop section and stop section ensure reliable positioning during operation. This dynamic design enables both quick connection/disconnection and stable connection when assembled.
Solution Approach 2:
The intermediate member is pre-prepared with a retaining section that can be deformed to connect to the object. The fastener is designed with pre-configured connecting and fastening sections. This preliminary preparation allows for quick assembly by simply inserting the fastener into the intermediate member and pressing it against the object, achieving both speed and reliability.
3Strength
If the retaining section is deformed under external force, then expansion connection to the object is achieved, but the structure becomes more complex
Solution Approach 1:
The retaining section utilizes elastic deformation as a parameter change to achieve expansion connection. When external force is applied, the retaining section deforms elastically to expand and connect to the object, then returns to its original shape when the force is removed. This parameter change approach maintains structural simplicity while achieving strong connection.
Solution Approach 2:
The retaining section is designed as a flexible component that can be deformed under external force to achieve expansion connection with the object. This flexible design allows the retaining section to adapt to the object's surface and create a secure connection without requiring complex mechanical structures.

Function Achieved in This Case
Enables stable and repeatable quick connection and disconnection of objects, ensuring secure assembly and disassembly without damage to the connected materials.
Implementation Method 1

Implementation Method 2
The connecting section is assembled to the intermediate member through expansion connection when an external force is applied to the connecting section

AI summary
A fastener structure and an assembling method thereof are introduced. The fastener structure includes a head portion and a body portion. The body portion is movably connected to the head portion and includes a connecting section for assembling to an intermediate member. The intermediate member includes a material retaining section and can be further connected to an object. Partial material of the object would move or flow into the material retaining section when the intermediate member is forcefully pressed against the object, so that the intermediate member and the object are connected together. Since the body portion can be assembled to the intermediate member and the intermediate member can be further connected to an object, and the fastener structure can be fastened to and released from a target object, at least two objects can be repeatedly and quickly connected to and disconnect from one another using the fastener structure.
