Rotatable Irrigation Hose Connector to Prevent Twisting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing irrigation hose connecting kits suffer from unwanted twisting issues due to rigid connections, making them difficult to use and requiring complex disentanglement, and also complicate the replacement of irrigation accessories.
Innovation Solution
A rotatable connecting kit for irrigation hoses featuring a male and female body with a polygonal intermediate portion and elastically yieldable plates that allow for free rotation, preventing twisting and simplifying attachment and detachment from water mains and accessories while maintaining the same dimensions and cost as prior art.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid connection is used between the hose and the connecting kit, then the connection stability is improved, but the hose cannot rotate freely causing twisting during use
Solution Approach 1:
The connecting kit incorporates a rotatable mechanism that allows the hose to rotate freely during use while maintaining a stable connection. The male and female bodies can rotate relative to each other, transforming the rigid static connection into a dynamic one that adapts to hose movement needs.
Solution Approach 2:
The connecting kit is divided into separate male and female bodies that can rotate independently. This segmentation allows one part to remain stable while the other rotates, resolving the contradiction between connection stability and rotation freedom.
2Ease of operation
If a free nut mechanism is used allowing rotation, then hose rotation is enabled, but the connection stability is reduced
Solution Approach 1:
The mechanism transitions from a completely free-rotating nut to a controlled rotation system where the male and female bodies can rotate relative to each other in a controlled manner, maintaining both rotation freedom and connection stability.
Solution Approach 2:
The intermediate portion with polygonal cross-section acts as a mediator between the male and female bodies, enabling controlled relative rotation while maintaining the connection integrity through the elastically yieldable plates.
3Object-affected harmful factors
If complex disentanglement operations are performed to prevent twisting, then hose twisting is eliminated, but the operational complexity increases
Solution Approach 1:
By enabling free rotation at the connection point, the hose can naturally adjust its orientation without twisting. The dynamic rotation capability eliminates the need for complex disentanglement operations, reducing operational complexity while preventing harmful twisting.
4Ease of manufacture
If the connecting kit dimensions are kept unchanged from prior art, then production cost and safety are maintained, but the rotatable mechanism adds structural complexity
Solution Approach 1:
The rotatable mechanism is achieved by segmenting the connector into male and female bodies with an intermediate portion, allowing rotation through their relative movement. This segmentation enables the rotatable function without significantly increasing overall dimensions or production cost.
Solution Approach 2:
The elastically yieldable plates provide flexible elements that enable rotation while maintaining connection integrity. These thin flexible components allow the rotatable mechanism to be implemented with minimal increase in overall size and manufacturing complexity.
