Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing watering equipment requires frequent screwing and unscrewing operations when reconfiguring hoses and water applicators, which is time-consuming and tedious, necessitating a solution for quick and efficient connection and disconnection.
Innovation Solution
A hose coupling device with a clamp nut design featuring a haptic region that guides the user's fingers for force application, combined with a screw nut that clamps the hose, allowing for quick coupling and decoupling without repeated screwing operations, and a main body with a through channel for water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screwing operations are used to connect and disconnect hoses and applicators, then the connection is secure and reliable, but the operation becomes time-consuming and tedious
Solution Approach 1:
The connection system is divided into two distinct parts: a male connector that remains permanently attached to the water tap, and a female connector on the hose that can be quickly attached and detached. This segmentation allows the permanent part to maintain secure connection while the removable part enables quick reconfiguration without screwing operations.
Solution Approach 2:
The male connector is pre-installed and permanently fixed to the water tap in advance. This preliminary action eliminates the need to repeatedly screw and unscrew connectors during reconfiguration, as only the female connector needs to be attached or detached from the hose end.
2Productivity
If quick coupling solutions are implemented to reduce screwing operations, then the operation speed increases, but the device complexity increases due to additional components
Solution Approach 1:
The male connector serves multiple functions: it provides a permanent attachment point on the water tap, acts as a quick-connect interface, and eliminates the need for separate coupling mechanisms. This multi-functionality achieves quick reconfiguration without significantly increasing overall system complexity.
Solution Approach 2:
The complex screwing mechanism is extracted and replaced with a simpler quick-connect interface. The male connector removes the need for repeated threading operations by providing a permanent, pre-installed connection point that requires only simple attachment/detachment of the female connector.
3Ease of operation
If the haptic region is positioned at the ends of the screw nut for easy grasping, then the ease of operation improves, but the manufacturing precision requirement increases due to threading constraints
Solution Approach 1:
The screw nut is designed with different properties at different locations: the ends provide grasping surfaces for ease of operation, while the middle section contains the threaded portion for precise engagement. This local differentiation allows each region to optimize its function without compromising the other.
Solution Approach 2:
The haptic region is positioned in the axial dimension of the screw nut, spaced from both ends, creating a distinct grasping zone separate from the threaded engagement zone. This spatial separation in one dimension allows independent optimization of grasping ease and threading precision without conflict.
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
The solution significantly improves user experience by reducing the need for repeated screwing and unscrewing, enhancing mobility and reconfiguration of watering equipment, while maintaining durability and ease of operation.
Implementation Method 1
An internal periphery of the annular body includes a threaded portion at the first end of the annular body
Implementation Method 2
The haptic region can be felt by the user and naturally guides the user's fingers to a desirable location on the clamp nut for the application of force
Implementation Method 3
selectively facilitate engagement of the hose coupling portion with a hose inserted at the hose coupling portion by exerting a clamping force on the hose responsive to tightening of the screw nut
