Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid sprayers lack portability and efficiency in applying chemicals and water for various applications, such as pest control and concrete cutting, due to manual operation and potential cross-contamination between different chemical uses.
Innovation Solution
A portable, battery-powered liquid sprayer system with interchangeable tanks and a motor-driven pump, allowing for selective engagement of sprayer tanks with a power unit, enabling efficient ejection of liquids and integration with tools like cut-off saws and core drills without the need for extensive cleaning between uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple interchangeable sprayer tanks are used to contain different chemicals, then versatility is improved, but device complexity increases and cleaning requirements increase to avoid cross-contamination
Solution Approach 1:
The patent employs disposable sprayer tanks that are discarded after use rather than cleaned and reused. This eliminates the need for complex cleaning procedures and reduces cross-contamination risks, while the tanks themselves remain relatively simple in design.
Solution Approach 2:
The sprayer system is divided into separate, interchangeable tank modules that can be independently replaced. Each tank is a self-contained unit with its own pump and fluid pathway, isolating different chemicals from each other and simplifying the overall system architecture.
2Productivity
If manual pumps or gravity feed are used in typical water tanks, then device complexity is reduced, but productivity and ease of operation deteriorate due to lack of powered operation
Solution Approach 1:
The powered pump system is designed to be universally compatible with multiple types of tanks (sprayer tanks, water tanks, chemical tanks). A single motorized pump unit can handle different fluids and applications, replacing the need for separate manual pumping mechanisms for each tank type.
Solution Approach 2:
Manual mechanical pumping operations are replaced with an electric motor-driven pump system. This substitution provides powered operation for higher productivity while the motor unit is integrated into the tank assembly, keeping the overall device complexity manageable.
3Adaptability or versatility
If typical sprayers are used for concrete cutting and coring applications, then adaptability is improved, but reliability deteriorates due to potential cross-contamination between different chemical uses
Solution Approach 1:
The sprayer tanks are designed as disposable units that are discarded after a single use or single chemical application. This eliminates cross-contamination between different chemicals (e.g., cutting fluids vs. coring fluids) and ensures reliable performance for each specific application without carryover contamination.
Solution Approach 2:
Each tank is a segregated, self-contained unit with dedicated fluid pathways and pumps. This segmentation prevents cross-contamination between different chemicals by physically isolating their storage and delivery systems, thereby maintaining reliability across different applications.
4Reliability
If extensive cleaning is performed between uses of sprayer tanks, then reliability is improved by preventing cross-contamination, but loss of time increases
Solution Approach 1:
Instead of cleaning tanks between uses, the system employs disposable tanks that are discarded after use. This eliminates the time-consuming cleaning process entirely while maintaining reliability by preventing cross-contamination through physical separation of different chemical applications.
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 system provides a portable, efficient means to apply liquids and water for diverse applications, preventing cross-contamination and enhancing operational convenience by using a single power unit with multiple tanks, ensuring effective use in various maintenance and construction tasks.
Implementation Method 1
a pump fluidly connected with the reservoir and the outlet. When the sprayer tank engages the power unit, the motor is operable to selectively drive the pump to pump liquid from the reservoir for ejection through the outlet
Implementation Method 2
The wand includes a mechanical valve in fluid communication with the pump, the mechanical valve being configured to inhibit the flow of liquid when closed and to permit the flow of liquid when open
