Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in connecting a female coupling part with a male coupling part that requires relative axial displacement, particularly with stiff tubes that cannot be moved or bent, necessitating a solution that is easy, safe, and compatible with existing couplings in industrial settings.
Innovation Solution
An assembly comprising a stiff tube with an attachment means and a male coupling part that allows relative axial displacement, utilizing a detachably connected element with a screw connection and a removable stop for secure engagement, enabling connection and disconnection without moving the stiff tube, and accommodating existing couplings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a male coupling part requiring relative axial displacement is used, then connection to female coupling part is enabled, but the stiff tube cannot be moved or bent to provide flexibility
Solution Approach 1:
The coupling system is divided into three main segments: the stiff tube, the male coupling part, and the female coupling part. The male coupling part can be detached from the stiff tube and reattached, allowing it to be positioned independently to achieve the necessary axial displacement for connection, while the stiff tube remains stationary and maintains its structural integrity.
Solution Approach 2:
The male coupling part is designed to be dynamically repositionable relative to the stiff tube. It can be detached, moved axially to the required position, and reattached, providing the flexibility needed for connection operations without requiring the stiff tube itself to be flexible or movable.
2Adaptability or versatility
If existing couplings are accommodated, then compatibility is maintained, but the connection process becomes complicated and cumbersome
Solution Approach 1:
The male coupling part is designed with universal compatibility to work with existing female coupling parts in the industry. By maintaining compatibility with standard couplings while incorporating the detachable design, the system achieves multi-functionality: it works with existing infrastructure and simplifies the connection process through easier positioning and attachment.
3Ease of operation
If a detachably connected element allowing axial displacement is used, then connection is enabled, but manufacturing complexity increases
Solution Approach 1:
The system is segmented into the stiff tube, male coupling part, and female coupling part, with the male coupling part being detachably connected. This segmentation allows each component to be manufactured separately using standard processes, avoiding the need for complex integrated manufacturing while still achieving the desired connection functionality.
Solution Approach 2:
The male coupling part is pre-assembled with the necessary connection features before being attached to the stiff tube. This preliminary preparation allows for simpler manufacturing of individual components and facilitates easier final assembly, reducing overall manufacturing complexity while enabling the required axial displacement capability.
