Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current roofing sprayers are ineffective in handling fluid materials with viscosities between 10,000 to 40,000 centipoise at 25° C., are costly, and require high maintenance due to difficulties in cleaning and handling.
Innovation Solution
A peristaltic pump-driven sprayer system with an elliptical tip is used to efficiently apply fluid materials with viscosities between 10,000 to 40,000 centipoise at 25° C. at a flow rate of 0.5 to 10 gallons per minute, featuring a compressor for compressed air delivery and a pouch-in-a-box system for ease of use and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current roofing sprayers are used to apply fluid material, then the application can be performed with standard equipment, but the system cannot handle fluid materials with viscosity of 10,000 to 40,000 centipoise
Solution Approach 1:
The patent changes the pumping mechanism from a standard pump to a peristaltic pump, which uses a different operating principle (mechanical compression of flexible tubing) that can effectively handle high viscosity fluids. This parameter change in the pump type enables the system to process fluid materials with viscosity of 10,000 to 40,000 centipoise that standard pumps cannot handle.
2Device complexity
If single pump systems are used for spraying, then the system structure can be simplified, but the maintenance cost and difficulty increase due to cleaning requirements
Solution Approach 1:
The peristaltic pump design extracts the fluid contact surfaces from the pump mechanism itself, placing them in replaceable flexible tubing. This allows the tubing to be easily removed and replaced without disassembling the pump mechanism, significantly reducing cleaning and maintenance complexity while maintaining a relatively simple overall system structure.
3Productivity
If manual application methods are used, then the equipment cost can be reduced, but the application rate decreases
Solution Approach 1:
The system uses a peristaltic pump that creates controlled hydraulic flow of the fluid material through flexible tubing to the spray nozzle. This hydraulic mechanism enables automated, high-speed application compared to manual methods, while the peristaltic design keeps equipment costs moderate by avoiding complex high-pressure hydraulic systems.

AI summary
This invention relates to a method and system of applying a fluid material to a roofing surface. By modifying a peristaltic pump-driven sprayer device, a fluid material having a viscosity of 10,000 to 40,000 centipoise at 25° C. can be effectively sprayed onto a roofing surface. Additionally, the use of a modified peristaltic pump-driven sprayer device allows for the fluid material to be applied onto the roofing surface at a faster rate than other spraying methods.
