Portable Sprayer Adapter for Liquid and Solid Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable sprayers require elaborate conversion measures to switch between liquid spray and solid dust operations, necessitating the storage and handling of separate assemblies that can be lost or misplaced.
Innovation Solution
A portable sprayer design featuring a detachable adapter with interchangeable liquid and solid channels, allowing for easy switching between modes by adjusting the installation position of the reservoir and adapter relative to the blower unit, eliminating the need for additional parts and simplifying the conversion process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate interchangeable components are used for liquid spray and solid dust operations, then the sprayer can be adapted to different applications, but the device complexity increases and parts can be lost or misplaced
Solution Approach 1:
The adapter is designed with both a liquid channel and a solids channel integrated into a single component, allowing the same adapter to handle both liquid spray and solid dust operations. This universal design eliminates the need for separate interchangeable components while maintaining adaptability to different applications.
Solution Approach 2:
The liquid channel and solids channel are merged into a single adapter component rather than being separate parts. This combining of functions into one piece reduces the number of parts that need to be managed and eliminates the risk of losing interchangeable components.
2Adaptability or versatility
If extensive modifications are made to convert between spray and dusting operations, then the sprayer can meet different application requirements, but the ease of operation decreases and conversion time increases
Solution Approach 1:
The adapter is designed as a detachable component that can be easily separated from the reservoir and blower unit, allowing quick conversion between operations by simply detaching and reattaching the same adapter in different orientations, rather than making extensive modifications to the entire sprayer system.
Solution Approach 2:
The adapter incorporates movable or adjustable elements that allow it to be reconfigured for different operations through simple detachment and reattachment, rather than requiring fixed, permanent modifications. This dynamic design enables easy conversion between spray and dusting modes.
3Adaptability or versatility
If the liquid channel and solids channel are always open, then both operations can be performed, but contamination and mixing of residues occurs
Solution Approach 1:
The unused channel (liquid or solids channel) is effectively taken out of service by closing its outlet or blocking its passage when not in use. This extraction of the non-active channel from the operational flow prevents contamination and mixing of residues while maintaining the ability to switch between operations.
Solution Approach 2:
A closing mechanism or barrier acts as an intermediary element that can be inserted into or activated within the unused channel to prevent contamination. This intermediary blocks the passive channel while allowing the active channel to function, enabling operational flexibility without contamination risks.
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 quick and efficient conversion between liquid spray and solid dust operations without mixing residues, reducing the risk of contamination and minimizing the number of parts required, thus enhancing usability and reducing operational complexity.
Implementation Method 1
The blower unit generates an airflow that distributes the product to the plants being treated
Implementation Method 2
This is drawn from the reservoir via a liquid channel and introduced into the blower airflow, for example, by means of a pressure pump
Implementation Method 3
The compressed air channel passes through the adapter into the interior of the reservoir. When closed, the reservoir is pressurized, facilitating the discharge of the liquid spray or the solid dusting agent

AI summary
The sprayer (1) has a blower unit (3) with a blower (6) driven by a drive motor (5), where the sprayer selectively spreads liquid spray or solid powder with blower air stream (7). An adapter (8) is detachably connected with a storage tank (4), and has channel sections of liquid and solid channels for the spray and powder. The mounting positions of the tank and the adapter are freely selectable relative to each other and/or the unit, where the liquid and solid channels are connected with the tank by the liquid and solid channel sections in two different mounting positions, respectively.
