Rotatable Floor Stripping Blade Angled for Fixture Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor covering removal machines struggle with removing coverings from areas like walls, windows, and corners, and have difficulty with hard and tightly bonded adhesives, as standard blades are not adaptable enough for these scenarios.
Innovation Solution
The development of floor stripping blade assemblies with a leading edge angled between 5° and 45° from the direction of travel, allowing for adjustable or fixed angles, which can rotate relative to the machine, and are designed to accommodate different blade profiles and orientations to effectively engage and lift floor coverings and adhesive around fixtures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard blades with leading edge perpendicular to direction of travel are used, then the machine can effectively remove floor coverings in open areas, but the blades are not adaptable for removing coverings around fixtures, walls, windows, or corners
Solution Approach 1:
The blade assembly is made rotatable about the longitudinal axis of the blade shank, allowing the blade orientation to be dynamically adjusted during operation. This enables the operator to change the blade's angular position to adapt to different removal scenarios such as working around fixtures, walls, windows, or corners, while maintaining ease of operation through simple rotation capability
2Adaptability or versatility
If standard blades are used, then the machine structure remains simple, but the blades cannot effectively remove hard and tightly bonded adhesives
Solution Approach 1:
The rotatable blade assembly allows dynamic adjustment of blade orientation to optimize contact with hard and tightly bonded adhesives. By rotating the blade to different angles, the operator can adapt the blade edge to effectively engage with various adhesive types and surface conditions without requiring multiple specialized blades or complex mechanisms
Solution Approach 2:
The invention changes the angular parameter of the blade leading edge relative to the direction of travel. By allowing the blade to rotate about the shank axis, the leading edge angle can be varied to optimize performance for different adhesive hardness levels and bond strengths, enabling effective removal of tough adhesives while maintaining a relatively simple blade assembly structure

AI summary
A floor stripping machine blade of a blade assembly has a leading edge, when the blade assembly is attached to a floor stripping machine, at an angle that is other than perpendicular to the direction of travel of the floor stripping machine, said angle of the blade's leading edge being fixed or adjustable.
