Non-Marking Cone Nut for Secure Tile Blade Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metal nuts used to connect grinder blades to saws often leave marks or chip tiles during cutting, especially when making angled or beveled cuts, reducing efficiency and increasing costs due to the need for recutting and replacing damaged tiles.
Innovation Solution
A non-marking, impact-resistant nut with a cone-shaped body and central tubular channel, made from materials like acetol, designed to securely attach grinder blades without marking or chipping tiles, featuring a seamless construction and configuration to fit flush against the grinder, ensuring secure attachment and minimizing contact damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal nut is used to connect the grinder blade to the saw, then the blade is securely attached, but the nut leaves marks or chips on the tile during cutting
Solution Approach 1:
The patent introduces a tile-cutting-specific nut as an intermediary component between the metal nut and the tile. This intermediate nut absorbs the harmful contact with the tile surface, preventing marks and chips while maintaining the secure attachment function of the original metal nut through its threaded connection.
Solution Approach 2:
The tile-cutting nut is designed as a disposable component that can be easily replaced. Instead of trying to make the metal nut non-marking, the invention uses a separate, inexpensive nut that serves its purpose for a single cutting operation and is then discarded, avoiding the need for expensive tile repairs.
2Ease of operation
If the nut contacts the tile during angled or beveled cuts, then the cutting function is achieved, but tile chipping occurs requiring recutting and replacement
Solution Approach 1:
The tile-cutting nut serves as a mediator that allows the cutting operation to proceed while protecting the tile from damage. Its design enables it to contact the tile during angled cuts without causing chipping, maintaining both cutting functionality and tile integrity.
Solution Approach 2:
The nut is designed with features that cushion or absorb the impact and contact forces before they can reach the tile surface. This beforehand cushioning prevents the transmission of harmful forces that would cause chipping during angled cutting operations.
3Device complexity
If conventional metal nuts are used, then the tool assembly is simple and robust, but tile damage requires recutting and replacement, reducing efficiency
Solution Approach 1:
The nut assembly is segmented into two separate components: the original metal nut for secure attachment and the tile-cutting nut for damage prevention. This segmentation allows each component to be optimized for its specific function while maintaining overall assembly simplicity.
Solution Approach 2:
By introducing a disposable tile-cutting nut, the system eliminates the need for expensive tile recutting and replacement. The low cost of the disposable nut compared to the cost of tile waste makes the increased assembly complexity worthwhile for improving productivity.
