Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning and grinding technologies fail to thoroughly clean and process textured synthetic floor coverings, as they struggle to reach and effectively clean deeper areas of structured surfaces, and lack effective abrasive products for sanding off old coatings.
Innovation Solution
A grinding and cleaning body with a flexible, profiled surface and a Velcro adaptation layer, equipped with a processing layer containing abrasive grains embedded in synthetic resin, which can be securely attached to machines and penetrate deep into structured surfaces for thorough cleaning and grinding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If soft roller brushes are used to reach deeper parts of the surface structure, then the coverage area is improved, but the overall cleaning effect deteriorates
Solution Approach 1:
The cleaning body is segmented into a rigid base body providing structural support and a flexible processing layer containing abrasive elements for actual cleaning. This segmentation allows the rigid part to maintain shape for effective abrasion while the flexible part adapts to surface contours
Solution Approach 2:
The cleaning body uses composite construction combining rigid and flexible materials. The base body is made of rigid material for structural integrity, while the processing layer uses flexible material with embedded abrasive grains, creating a composite structure that simultaneously achieves both coverage and cleaning effectiveness
2Adaptability or versatility
If flexible grinding wheels are used to grind floor coverings, then the adaptability to surface contours is improved, but the grinding effectiveness on textured surfaces deteriorates
Solution Approach 1:
Different parts of the cleaning body have different properties: the base body is rigid for structural support, while the processing layer is flexible for surface adaptation. The abrasive grains themselves have localized sharp edges for effective cutting. This local differentiation of properties enables both adaptability and grinding effectiveness
Solution Approach 2:
The processing layer is designed to be flexible and dynamic, allowing it to adapt its shape to match the contours of the floor surface being cleaned. This dynamic adaptation enables the abrasive elements to maintain contact with uneven surfaces while the rigid base body provides stable mounting
3Productivity
If abrasive products are used to sand off old PU coatings, then the removal rate is improved, but the risk of surface damage deteriorates
Solution Approach 1:
The abrasive grains are embedded in a flexible processing layer that can adapt its pressure distribution. The flexibility allows the abrasive elements to conform to the surface, distributing the grinding force more evenly and reducing concentrated stress points that could cause damage, while maintaining effective removal rate
