Squeegee Deflector Structure for Better Debris Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing squeegee devices fail to effectively collect debris, allowing it to flow over or around the blade, resulting in reduced pushing efficiency.
Innovation Solution
Incorporation of a deflector with a concave curvature and a blade support configuration that secures a squeegee blade, preventing debris from flowing over or around the blade by using a deflector with a lower portion that depends upward and an upper portion with a leading edge forward, along with a bridge that offsets the lower portion, enhancing debris collection and pushing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional squeegee blade is used, then the device is simple in structure, but it fails to collect all debris allowing flow over and around the blade
Solution Approach 1:
The squeegee device is segmented into multiple functional components: a traditional squeegee blade for primary debris removal, and additional collection features (deflectors, concave curvatures) that create separate debris collection zones. This segmentation allows each component to handle specific aspects of debris collection, improving overall effectiveness without requiring a complete redesign of the entire device.
Solution Approach 2:
The invention adds vertical dimension elements to the traditionally horizontal squeegee blade by incorporating deflectors that extend upward and concave curvatures that create depth. This dimensional addition creates three-dimensional debris collection zones that prevent debris from flowing over or around the blade, thereby improving collection effectiveness while maintaining structural simplicity.
2Productivity
If a squeegee blade alone is used, then the device is easy to manufacture, but pushing efficiency is reduced due to debris flowing around the blade
Solution Approach 1:
The invention merges the traditional squeegee blade with additional collection features into a single integrated device. The deflectors and concave curvatures are combined with the blade assembly to create a unified structure that maintains manufacturing simplicity while significantly improving pushing efficiency by preventing debris from bypassing the blade.
Solution Approach 2:
The invention introduces concave curvatures to the squeegee structure, creating curved surfaces that guide debris flow more effectively. These curved elements help channel debris toward the blade and prevent it from flowing around the edges, thereby improving pushing efficiency while remaining compatible with standard manufacturing processes.
3Reliability
If no collection features are added, then the device complexity remains low, but debris flows over and around the blade reducing collection ability
Solution Approach 1:
Rather than adding collection features across the entire squeegee device, the invention applies them locally at critical areas where debris tends to escape. The deflectors are positioned at the leading edge to prevent debris from flowing over, while concave curvatures are created at the sides to prevent debris from flowing around. This localized approach improves collection ability while minimizing the increase in device complexity.

AI summary
A squeegee device is provided that includes a blade support and a deflector. The blade support has a front support and a rear support, which are configured to secure a squeegee blade therebetween. The deflector has a lower portion and an upper portion, which are configured so that the lower portion of the deflector depends upward from the blade support and a leading edge of the upper portion is forward, with respect to a pushing direction, from the blade support.
