Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for coating materials with liquid resin and applying them to surfaces for roofing or waterproofing are cumbersome, require extensive cleaning, and often involve rotatable rollers that complicate the process, making them inefficient and difficult to maneuver.
Innovation Solution
A device with a frame and a vessel for retaining resin, featuring curved guide members that ensure a pre-specified amount of resin is saturated into the material as it passes through a slot and passageway, allowing for efficient coating and application without rotatable rollers, facilitating easy cleaning and maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rotatable rollers are used for coating material with resin, then the coating process can be performed, but the device becomes cumbersome and requires extensive cleaning
Solution Approach 1:
The patent removes rotatable rollers from the coating device, extracting the problematic component that caused cumbersome operation and extensive cleaning requirements. The coating function is achieved through alternative means (coating head with reservoir and applicator elements) that do not involve rotatable rollers, thereby simplifying the device structure and easing cleaning procedures.
Solution Approach 2:
The coating device is divided into separate functional components: a coating head with resin reservoir, applicator elements (such as brushes or rollers that are part of the head assembly rather than drive rollers), and material guidance components. This segmentation allows each component to be optimized for its specific function and facilitates easier cleaning and maintenance of individual parts.
2Productivity
If existing coating devices are used, then resin application can be performed, but cleaning time increases and maneuverability decreases
Solution Approach 1:
By removing rotatable rollers and simplifying the device structure, the patent reduces the number of components that require cleaning, thereby decreasing cleaning time. The simplified design also improves maneuverability by reducing mechanical complexity and weight.
Solution Approach 2:
The patent employs disposable or easily replaceable applicator elements (such as brush covers or foam rollers) that can be quickly changed rather than cleaned, significantly reducing cleaning time and maintaining high productivity while improving device maneuverability.
3Manufacturing precision
If resin is applied manually with brush or roller, then coating can be performed, but resin application consistency varies
Solution Approach 1:
The coating head design incorporates features that provide feedback on resin flow and application uniformity, such as controlled reservoir feed mechanisms and applicator elements designed to maintain consistent resin distribution. This ensures uniform coating thickness and quality while maintaining efficient coating speeds.
Solution Approach 2:
The patent replaces manual brushing or rolling operations with a mechanized coating head system that uses controlled resin delivery mechanisms (such as pump systems, capillary action, or pressure-regulated flow) to apply resin uniformly, eliminating human variability while maintaining high coating productivity.

AI summary
A device for saturating material with resin and subsequently laying the saturated material onto a surface includes a frame and a vessel for retaining the resin attached to the frame. The vessel has a slot sized and configured so that material is passable through the slot after being coated with resin retained in the vessel. A first guide member is positioned adjacent the slot and a second guide member is positioned adjacent the slot and is spaced apart from the first guide member to define a passageway between the first and second guide members. The passageway is sized and configured for the material to be passable through the passageway and out of the device for laying on the surface. Embodiments of the device can be usable for methods of waterproofing and/or roofing.
