Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sprayers have a single function and cannot simultaneously perform blowing and spraying operations.
Innovation Solution
A sprayer design incorporating a housing assembly, spray nozzle assembly, and fan assembly, where the fan assembly generates airflow that propels a rotating blade to atomize and eject liquid through the spray nozzle, enabling both blowing and spraying capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-function sprayer design is used, then the device is simple and easy to manufacture, but it cannot perform both blowing and spraying operations
Solution Approach 1:
The sprayer is designed with a universal structure that can perform multiple functions: spraying (atomizing liquid medicine) and blowing (propelling objects with airflow). The housing assembly contains both a spray nozzle assembly for liquid atomization and a fan assembly for air flow generation, allowing the single device to replace multiple separate tools and improve functional versatility
Solution Approach 2:
The patent combines previously separate spraying and blowing functions into a single integrated device. The housing assembly merges the spray nozzle assembly and fan assembly into one unified structure, enabling both functions to be performed simultaneously or separately from a single device, thereby reducing the need for multiple separate tools
2Productivity
If airflow is used to propel the blade for atomization, then spraying distance and atomization effect are improved, but energy consumption increases
Solution Approach 1:
The system uses the fan-generated airflow to simultaneously serve multiple purposes: it propels the blade for liquid atomization and provides the blowing function. The airflow that would otherwise be wasted is utilized to drive the atomization process, creating a self-service mechanism where the same energy source performs multiple functions and reducing overall energy consumption
Solution Approach 2:
The airflow acts as an intermediary that transfers energy from the fan to the liquid atomization process. Instead of using a separate motor to drive the atomizing blade, the airflow mediates the energy transfer, using the kinetic energy of the moving air to propel the blade and atomize the liquid, thereby improving spraying distance while managing energy consumption
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 sprayer achieves improved applicability by allowing simultaneous blowing and spraying, enhancing atomization and increasing the spraying distance of the liquid.
Implementation Method 1
the air flow generated by the fan assembly propels the first blade to rotate
Implementation Method 2
the spray nozzle assembly is configured to atomize and eject the liquid from the housing assembly

AI summary
A sprayer includes a housing assembly, a spray nozzle assembly and a fan assembly. The housing assembly is connected to the spray nozzle assembly. The housing assembly is configured to hold liquid, and the fan assembly is configured to generate air flow. The spray nozzle assembly is configured to atomize and spray the liquid from the housing assembly, and blowout the air flow generated by the fan assembly. When the blowing is needed, the air flow generated by the fan assembly passes through the spray nozzle assembly and flows outward. When the spraying is needed, the spray nozzle assembly atomizes and sprays the liquid from the housing assembly. The sprayer is capable of blowing and spraying, which enables the spray to have an improved applicability.
