Pressurized Sprayer With Removable Compressor for Continuous Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressurised sprayers face issues with pressure loss during use, requiring manual repressurisation, and external compressor modules complicate use in public spaces due to dependency on additional equipment and complex tank designs that lead to stress concentration and potential leaks.
Innovation Solution
A pressurised sprayer with a removable, external compressor module, a standardised valve stem, and a stable tank design with a convex shape, allowing for independent pressurisation and reduced stress concentration, along with a base for stability and a suction tube for precise flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual pressurisation is used, then the sprayer can be pressurised without additional equipment, but the tank loses pressure gradually during spraying requiring work to stop and manual repressurisation
Solution Approach 1:
The sprayer system performs pressurisation automatically during operation. The compressor module activates when pressure drops, compressing air through the inlet valve to maintain tank pressure without user intervention, allowing continuous spraying work
Solution Approach 2:
The system maintains continuous pressurisation during spraying by automatically activating the compressor when pressure drops. This ensures uninterrupted spraying operation without stopping to manually repressurise the tank
2Productivity
If external compressed air line or compressor is used, then continuous pressurisation is possible, but additional equipment is required that is not accessible in public spaces
Solution Approach 1:
The compressor module and tank are integrated into a single portable sprayer unit. The compressor, battery, control unit, and tank are combined in one device, eliminating the need for external compressed air lines or separate compressors
Solution Approach 2:
The sprayer contains a self-contained compressor module with battery power that can operate independently without external compressed air infrastructure. This makes the device universally applicable in various locations including public spaces where external compressors are unavailable
3Device complexity
If complex tank shape with irregular geometry is used, then the compressed air inlet connection can be integrated, but stress distribution becomes uneven causing high internal stresses and potential leakage
Solution Approach 1:
The tank is designed with a substantially spherical shape, which is the optimal geometric form for withstanding internal pressure. This spherical geometry ensures uniform stress distribution across the tank walls, avoiding stress concentration and potential leakage points
4Device complexity
If compressor module has specific connection design, then it can be integrated with the tank, but replacement and connection to compressed air installations becomes difficult
Solution Approach 1:
The compressor module is designed as a separable, removable unit from the tank. This modular design allows the compressor module to be easily detached and replaced without affecting the tank or other components, simplifying maintenance and repairs
