Dual-Function Water Spray Nozzle With Switchable Flow Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water nozzles have limited functionality, often requiring separate shower heads for different water flow rates or settings, which are complex and costly.
Innovation Solution
A dual-function water spray nozzle with a movable adjustment assembly and elastic member that allows for two selectable flow passage regions, enabling switchable shower and aerated water spray settings, and uses a fixation member with complementary structures for secure connection and adjustable flow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a shower head is used to provide different water flow rates or spray settings, then the water spray functionality is improved, but the device complexity and cost increase
Solution Approach 1:
The nozzle body integrates multiple spray settings (shower spray, aerated water spray, and other spray patterns) within a single nozzle structure, eliminating the need for separate shower heads for different spray requirements. The fixed spray settings are designed into the nozzle body with different spray angles and patterns, allowing one nozzle to perform multiple functions that previously required multiple devices.
Solution Approach 2:
The invention combines the functions of multiple nozzles with different spray settings into a single integrated nozzle assembly. The nozzle body incorporates multiple spray outlets with different geometries and orientations, merging what would have been separate shower head components into one unified structure that provides diverse spray options.
2Adaptability or versatility
If a shower head is used to provide different water flow rates or spray settings, then the water spray functionality is improved, but the cost increases
Solution Approach 1:
The nozzle body is designed as a universal component that provides multiple spray settings (shower spray, aerated water spray, and other patterns) within a single manufactured part. This multi-functional design eliminates the need to manufacture and stock multiple different shower heads, reducing production costs and inventory requirements while maintaining diverse spray options for consumers.
3Adaptability or versatility
If the adjustment assembly is made movable to enable switching between settings, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The adjustment assembly incorporates a movable component that can shift between different positions to select between spray settings. This dynamic element allows the nozzle to switch between fixed spray patterns (shower spray, aerated water spray, etc.) by changing the flow path configuration, providing adaptability through controlled movement rather than requiring multiple fixed nozzles.
Solution Approach 2:
The adjustment assembly is segmented into distinct components including a movable element and a fixed element, allowing independent movement of the adjustable portion while maintaining the integrity of the overall nozzle structure. This segmentation enables simple switching between settings without requiring complex reconfiguration of the entire nozzle assembly.
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 nozzle provides user-friendly, adaptable water spray settings that automatically revert to the previous setting upon closure, meeting various flow requirements without additional components, enhancing usability and cost-effectiveness.

AI summary
A dual-function water spray nozzle includes a housing, a fixation member, an adjustment assembly, and an elastic member. The fixation member is connected to an interior of the housing, the fixation member has a water inlet channel extending through to an end, and a plurality of water passage ports in communication with the water inlet channel are provided. The adjustment assembly is movably arranged in an area between the housing and the fixation member. The adjustment assembly includes an adjustment joint and a switching member arranged in the adjustment joint. A first flow passage region is formed between the switching member and the fixation member, a second flow passage region is formed between the adjustment joint and the switching member, and the water passage ports are selectively connected to the first flow passage region or the second flow passage region. The elastic member enables the nozzle to restore.
