Elastically Deformable Ring for One-Handed Pipe Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting pipes to tubular bodies are complex and require both hands for mounting, lacking efficient axial locking and anchoring mechanisms.
Innovation Solution
A one-piece ring with two rigid sectors hinged by an elastically deformable annular portion, featuring anchoring studs with circumferential grooves for secure engagement with pipe housings, allowing for easy mounting with one hand and enhanced axial locking under fluid pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fastening rings are used, then axial locking is achieved, but mounting requires two hands and is complex
Solution Approach 1:
The fastening ring is divided into two rigid sectors connected by an elastically deformable annular portion, allowing the ring to be opened and mounted with one hand while maintaining structural integrity and locking capability when closed
Solution Approach 2:
The annular portion is made elastically deformable, enabling the ring to dynamically change shape during mounting (opening) and operation (closed), facilitating easy installation while maintaining secure axial locking
2Reliability
If anchoring studs are added to improve axial locking, then connection reliability increases, but device complexity increases
Solution Approach 1:
The anchoring studs are integrated directly into the rigid sectors of the fastening ring, combining the locking function with the ring structure itself rather than adding separate components, thereby improving reliability without significantly increasing device complexity
3Strength
If grooves are added to anchoring studs for better anchoring, then connection strength increases, but manufacturing complexity increases
Solution Approach 1:
The grooves in the anchoring studs are designed with specific geometric parameters that allow the pipe wall to penetrate and deform the stud material under fluid pressure, creating a mechanical interlock that enhances anchoring strength while remaining manufacturable through standard processes
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
Facilitates simple, one-handed mounting and ensures secure, leak-tight connections by allowing the pipe wall to penetrate the grooves under fluid pressure, providing robust anchoring and reducing the risk of accidental detachment.
Implementation Method 1
two rigid sectors which are hinged to one another by at least one elastically deformable annular portion
Implementation Method 2
under the pressure of the fluid flowing in the pipe, the wall of the pipe will penetrate inside the grooves of the studs thus ensuring locking of the studs in the housings
