Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held chemical sprayers lack portability, efficiency, and convenience in handling and storage, particularly when needing to be stored in standard five-gallon buckets.
Innovation Solution
A portable, battery-powered liquid sprayer with a detachable wand and quick-release mechanism, featuring a motor-driven pump system, a mechanical valve assembly, and a micro switch for actuation, allowing easy assembly and disassembly for storage in a five-gallon bucket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the sprayer uses a motor-driven pump system with battery power, then liquid distribution efficiency and pressure control are improved, but device complexity and weight increase
Solution Approach 1:
The sprayer is divided into separate functional modules: a body assembly containing the motor and pump, a detachable wand assembly with nozzle, and a separate battery. This segmentation allows each component to be optimized independently and facilitates easier storage and maintenance while maintaining overall system efficiency.
Solution Approach 2:
A micro switch acts as an intermediary between the trigger mechanism and the motor, providing precise electrical actuation control. This intermediary component enables reliable motor engagement and disengagement through simple mechanical trigger input, improving system control without adding complexity.
2Ease of operation
If the wand is made detachable with quick-release mechanism, then ease of storage and handling is improved, but connection reliability and sealing may worsen
Solution Approach 1:
The wand is designed as a separate, detachable assembly that can be quickly removed from the body. This segmentation enables convenient storage separate from the main unit while maintaining a reliable connection during operation through the quick-release mechanism.
Solution Approach 2:
The wand assembly is extracted as a separate component that can be independently stored or disposed of. This extraction allows the main body to be compact for storage in standard containers while the wand can be stored separately or attached when needed, improving overall storage convenience.
3Volume of moving object
If the sprayer is designed to fit in standard five-gallon buckets, then storage portability is improved, but ergonomic design and handling comfort may worsen
Solution Approach 1:
By segmenting the sprayer into a compact body assembly and a separate wand, the main body can be sized to fit within standard five-gallon buckets for portable storage. The wand can be attached during operation to provide ergonomic handling, separating storage requirements from operational comfort requirements.
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 efficient liquid distribution with adjustable pressure and flow rate, and facilitates convenient storage and handling by allowing the sprayer to fit within a standard five-gallon bucket while maintaining ergonomic design for user comfort.
Implementation Method 1
a battery removably coupled to the body assembly and operable to supply power to the motor
Implementation Method 2
a motor and a pump... operable to supply power to the motor to drive the pump
Implementation Method 3
The liquid agent can be any number of liquid agents including pesticides, fertilizers, insecticide, termiticide, germicide, or other chemical agents

AI summary
A portable, battery-powered liquid sprayer includes a supply tank assembly, a body assembly, a battery, and a wand. The supply tank assembly holds a liquid to be sprayed. The body assembly is selectively coupled to and supported by the supply tank assembly. The body assembly receives a motor and a pump. The battery is removably coupled to the body assembly and is operable to supply power to the motor. The wand is moveable relative to the body assembly and is in fluid communication with the supply tank assembly. The wand includes a nozzle, and the wand is operable to activate the motor, which drives the pump to pump the liquid from the supply tank assembly to eject the liquid from the nozzle.
