Angled Floor Squeegee Blade Assembly for Resin-Free Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current floor squeegees face issues with resin hardening on fasteners, difficulty in changing blades, and poor alignment due to the angle of the squeegee frame and blade, which complicates the application and removal of resinous materials.
Innovation Solution
A floor squeegee design featuring an elongate frame with internally threaded locator bosses, a flexible squeegee blade with corresponding boss holes, and a clamp section with internal threading, allowing for easy assembly and preventing resin contact with fasteners, with angled sections for improved accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the squeegee frame has an angle with the blade as in current designs, then the squeegee can spread resin effectively, but the fastener nuts are in closer proximity to resinous materials causing them to harden on the fasteners
Solution Approach 1:
The fastener nuts are extracted from the frame structure and relocated to the blade assembly. The blade now includes externally threaded fasteners that engage with internally threaded holes in the frame, separating the fastening function from the frame and preventing resin contact with fasteners during application.
Solution Approach 2:
The threading configuration is inverted: instead of internally threaded holes in the blade engaging externally threaded fasteners in the frame (current design), the blade has externally threaded fasteners that engage internally threaded holes in the frame. This inversion moves fasteners away from resin contact zones.
2Ease of manufacture
If the fastener nuts are exposed on the frame as in current designs, then assembly is simple, but resinous materials harden on the exposed fasteners making blade removal and replacement difficult
Solution Approach 1:
The fastener nuts are extracted from the frame and relocated to the blade assembly. The blade includes externally threaded fasteners that engage with internally threaded holes in the frame, preventing resin contact with fasteners and enabling easy blade removal by simply unscrewing the externally threaded fasteners from the frame.
Solution Approach 2:
The blade assembly with integrated fasteners can be quickly removed and replaced as a unit when the blade wears or needs changing. The externally threaded fasteners enable rapid detachment without tools or complex disassembly, treating the blade as a replaceable component.
3Device complexity
If the squeegee frame has an angle with the blade as in current designs, then the squeegee structure is compact, but it puts fastener nuts in closer proximity to resinous materials being applied
Solution Approach 1:
The fastener nuts are extracted from the frame structure and relocated to the blade assembly. The blade includes externally threaded fasteners that engage with internally threaded holes in the frame, moving fasteners away from resin contact zones during application while maintaining structural integrity.
Solution Approach 2:
The blade assembly acts as an intermediary between the frame and the fastening function. By integrating externally threaded fasteners into the blade, the design mediates the connection while keeping fasteners isolated from resinous materials that contact the blade edge during application.
4Device complexity
If current floor squeegee frames do not have boss holes, then the frame structure is simpler, but alignment of the flexible squeegee blade is difficult
Solution Approach 1:
The frame includes pre-formed internally threaded holes (boss holes) at precise locations that guide and align the blade assembly during installation. These pre-positioned holes ensure accurate alignment of the blade with the frame before the externally threaded fasteners are screwed in, eliminating alignment difficulties.
Solution Approach 2:
The internally threaded holes in the frame act as alignment intermediaries, providing precise positioning features that guide the blade assembly into correct alignment during installation. These holes mediate between the frame structure and the blade, ensuring accurate positioning before final fastening.

AI summary
There is disclosed a floor squeegee for spreading resin on floors or removing liquid spills or debris from floors and other flat surfaces. The squeegee includes a frame section, a handle connected to the frame section such that the frame section is generally perpendicular to handle, the frame section including a preset number of internally threaded locator bosses. A flexible squeegee blade section includes a preset number of boss holes extending therethrough to receive the preset number of internally threaded locator bosses. The flexible squeegee blade section has a first section and a second section being integrally formed with the first elongate section and being inclined at an angle with respect to the first section in a range from about 0 to about 90°. The squeegee includes a clamp section having a preset number of boss holes extending therethrough to receive the preset number of internally threaded locator bosses, and a preset number of threaded nuts with the preset number of threaded nuts being threaded to be threadably received in the internally threaded locator bosses. When assembled the second blade section contacts a floor or other surface when in operation.
