Solution Overview

Problem

Existing sprayers for mixing solutions with clear water are aesthetically unpleasing, inefficiently dilute liquids, and have exposed air inlets that can be blocked, limiting bubble generation and concentration control.

Innovation Solution

A sprayer with an operation portion connected to a hose and housing, featuring a diversion chamber, distribution channels, and a siphon channel with a valve for adjustable liquid flow, allowing for selective alignment of diversion ports to control the concentration and flow of mixed solutions and clear water, enabling adjustable concentration and spray patterns through a spray head with multiple nozzles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If liquid is continuously diluted by water flowing into the container after each spraying process, then the sprayer can maintain operation, but the liquid concentration control is lost and the design becomes aesthetically unpleasing

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoidliquid concentration control
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The sprayer is divided into separate functional chambers: a liquid storage chamber that maintains concentrated liquid, and a mixing chamber where dilution occurs only during spraying. This segmentation prevents continuous dilution in the storage container while enabling controlled dilution during operation, maintaining both continuous operation capability and concentration control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A valve mechanism acts as an intermediary between the liquid storage chamber and the mixing chamber, controlling when and how much liquid is transferred for dilution. This intermediary component enables precise concentration control by regulating the dilution process rather than allowing uncontrolled continuous mixing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If exposed air inlets are used for bubble generation, then the sprayer can create bubble solution, but the air inlets may be blocked affecting bubble generation

Engineering Contradiction:
Improvebubble solution capabilityVSAvoidair inlet functionality
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The air inlet is repositioned from an exposed external location to an internal location within the housing structure. By integrating the air inlet into the internal architecture of the sprayer, the design eliminates exposure to external blockages while maintaining the bubble generation function through internal air mixing.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If a simple mixing structure is used, then the sprayer is easier to manufacture, but the ability to adjust concentration and flow is limited

Engineering Contradiction:
Improvestructural simplicityVSAvoidconcentration and flow adjustment
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The sprayer incorporates adjustable components including a variable orifice valve for concentration control and a flow rate adjustment mechanism. These dynamic elements allow the simple mixing structure to adapt to different spraying requirements, providing concentration and flow adjustment capabilities without significantly complicating the overall manufacturing process.

Inventive Principle:
Principle #15Dynamics

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

Enables adjustable concentration and flow of mixed solutions and clear water, improving bubble generation and aesthetic appeal by allowing for precise control of liquid and air mixing, enhancing usability and effectiveness in spraying fertilizers, pesticides, or detergents.

Implementation Method 1

Water is introduced by the operation portion to generate a negative pressure. Thereby liquid in the container is delivered to the siphon channel through the liquid pipe due to siphon effect.

Methodology Applied
Scientific EffectSiphon effect: Syphon

Implementation Method 2

the liquid is drawn into the liquid storage room and mixed with clear water from the second diversion port to form a diluted solution. Lastly the diluted solution is blended with air in the mixture channel to get bubble solution

Methodology Applied
Scientific EffectMixing:

AI summary

A sprayer able to adjust a flow of mixed solution and clear water is revealed. The sprayer can be used for clearing objects or to spray mixed solution for agricultural purposes. The mixed solution is formed by liquid mixed with clear water while the liquid can be fertilizers, pesticides, or detergents. The sprayer not only can spray out the mixed solution or clear water selectively, but also can adjust concentration and flow of the liquid.
