Pivotable Floor Finishing Units with Vacuum Dust Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sanding and refurbishing hardwood floors is a difficult DIY task, and unfinished concrete or cement floors are prone to dust and staining due to their porosity and scuffing from traffic.
Innovation Solution
A floor finishing machine with a base frame, movable frame, and pivotable floor finishing units, along with a jack for height adjustment and a vacuum tank for dust management, allowing for efficient and adaptable floor finishing on uneven surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If hardwood floors are sanded and refurbished, then the floor surface is restored and improved, but the task becomes difficult and time-consuming for DIY users
Solution Approach 1:
The floor finishing units are made pivotable about both longitudinal and transverse axes, allowing dynamic adjustment to follow the contours of uneven floors. This mobility enables the machine to adapt to various floor conditions while maintaining consistent finishing quality, reducing the skill level required for effective operation.
Solution Approach 2:
The floor finishing machine uses multiple discrete floor finishing units that can be independently positioned and adjusted. This segmentation allows each unit to be optimized for specific areas and enables easier maintenance or replacement of individual components, simplifying the overall operation for DIY users.
2Strength
If concrete or cement floors are left unfinished, then the material maintains its inherent strength and low cost, but the floor produces dust and is susceptible to staining
Solution Approach 1:
The vacuum system is integrated to capture and remove dust particles generated during the finishing process, converting the harmful dust byproduct into a controlled situation. The vacuum tank collects dust that would otherwise contaminate the environment, allowing the concrete floor to be finished without generating harmful dust clouds.
3Stability of the object's composition
If the floor surface is uneven, then the floor reflects natural variations, but the finishing machine must maintain consistent contact and performance
Solution Approach 1:
The floor finishing units are mounted on pivotable arms that can dynamically adjust their position relative to the floor surface. This dynamic capability allows the units to maintain consistent contact and finishing performance across uneven surfaces, adapting to local variations in floor height and contour.
Solution Approach 2:
The pivotable mounting mechanism adds rotational degrees of freedom in multiple dimensions, allowing the floor finishing units to compensate for surface variations. This multi-dimensional adjustment capability enables the machine to maintain stable operation on uneven floors that would otherwise prevent consistent finishing.

AI summary
A floor finishing machine includes a base frame, a movable frame movably mounted to the base frame, and a plurality of floor finishing units carried by the movable frame, and being pivotable about a generally longitudinal pivot axis and a generally transverse pivot axis. The machine may also include a jack operatively coupled between the base frame and the movable frame, and a vacuum tank carried on the movable frame and straddling the jack.
