Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing drizzle type spray apparatuses lack the ability to adjust spray direction, requiring multiple nozzles and fixed positions to achieve desirable drizzle type spray angles.

Innovation Solution

A spray-angle-changing nozzle device with an adjustable member comprising a cylindrical tube structure and a connecting member with threaded and shaft receiving portions, allowing the sprinkle head to be rotated for adjustable spray direction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple nozzles are used to achieve desirable drizzle type spray angles, then the spray coverage is improved, but the device complexity increases

Engineering Contradiction:

Improvespray angle coverageVSAvoidnumber of nozzles

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The nozzle is made rotatable through a rotation adjustment mechanism, allowing a single nozzle to dynamically change its spray direction and cover multiple angles. This replaces the static multiple nozzles configuration with a dynamic single nozzle system, reducing device complexity while maintaining spray coverage versatility

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The single nozzle is equipped with adjustment capabilities to perform multiple spray direction functions, making it universal in covering various spray angles. The rotation adjustment mechanism enables one nozzle to fulfill the role previously requiring multiple fixed nozzles

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Manufacturing precision

If nozzles are fixed in predefined positions to achieve desirable drizzle type spray angles, then the spray direction is controlled, but the ease of operation decreases

Engineering Contradiction:

Improvespray direction controlVSAvoidspray angle adjustment

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The fixed nozzle position is transformed into a rotatable nozzle configuration through the rotation adjustment mechanism. This allows the spray direction to be dynamically adjusted during operation while maintaining precise control over the drizzle type spray angles, improving ease of operation without sacrificing manufacturing precision

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The rotation adjustment mechanism serves as an intermediary between the fixed mounting structure and the nozzle, enabling controlled movement and adjustment of spray direction. This mediator component provides the necessary flexibility for operation while maintaining precise spray control

Inventive Principle:

Principle #24Intermediary (Mediator)
