Reusable Quick Coupler Structure for Fast Sealed Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional quick couplers allow for fast assembly only once due to deformation during initial mounting, preventing reuse.
Innovation Solution
A quick coupler design featuring a top ring and bottom ring with annular grooves and fasteners that allow for detachable and reusable assembly through a combined component structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional quick coupler uses housing deformation to engage the connecting key, then fast assembly is achieved, but the coupler cannot be reused due to permanent deformation
Solution Approach 1:
The quick coupler is divided into multiple detachable components including a first quick coupler body, a second quick coupler body, and a connecting component. This segmentation allows each part to be replaced independently, enabling reuse of the main coupler bodies after disassembly and replacement of worn connecting components.
Solution Approach 2:
The invention changes the connection mechanism from permanent deformation to reversible elastic deformation or mechanical interlocking. The housing uses elastic deformation to engage and disengage the connecting key, allowing multiple assembly cycles without permanent damage, thereby enabling reuse.
2Ease of operation
If a conventional quick coupler uses permanent deformation for connection, then single-use fast assembly is achieved, but repair and maintenance become difficult
Solution Approach 1:
The connecting component is designed as a separate replaceable part that can be easily detached and replaced. This segmentation allows maintenance personnel to quickly replace worn connecting components without replacing the entire coupler, significantly improving ease of repair and maintenance.
Solution Approach 2:
The design allows worn connecting components to be discarded and replaced with new ones, while the main coupler bodies are recovered and reused. This approach makes maintenance economical and convenient by separating consumable parts from durable parts.
3Ease of manufacture
If a conventional quick coupler is designed as a single integrated structure, then manufacturing is simpler, but reuse and maintenance are compromised
Solution Approach 1:
The quick coupler is segmented into modular components that can be manufactured separately and then assembled. This segmentation maintains manufacturing simplicity for each individual component while enabling reuse and maintenance of the overall system through selective replacement of parts.
Solution Approach 2:
The first and second quick coupler bodies are designed as universal components that can be reused across multiple assembly cycles. The connecting component serves multiple functions including mechanical engagement and providing a replacement interface, making the overall system both manufacturable and reusable.

AI summary
A quick coupler includes a top ring, a bottom ring, a left fastener and a right fastener, the top ring which includes a top ring left fixing head, a top ring right fixing head and has a top ring groove, the bottom ring which includes a bottom ring left fixing head, a bottom ring right fixing head, an arc bottom ring left part, an arc bottom ring right part, a bottom ring middle shaft member, and has a bottom ring groove, wherein when the left fastener and the right fastener are fastened, the arc bottom ring left part and the arc bottom ring right part come in contact with the arc top ring, such that the top ring groove of the arc top ring and the bottom ring groove of the arc bottom ring form a continual sealed annular groove at an inner side of the quick coupler.
