Thread-Cleaning Nut With Integrated Bristles For Corrosion Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for removing corrosion and dirt from threaded members like flanges, studs, and bolts often require specialized tools and unconventional angles, making it difficult to access and clean these components effectively.
Innovation Solution
A specialized nut with bristles positioned on its edge, which are stiff enough to abrade the threads, allowing for cleaning without additional tools or clearance, and can be used with conventional fastening tools or power tools to effectively remove corrosion and dirt from threaded members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cleaning methods are used, then cleaning effectiveness is improved, but accessibility and ease of operation deteriorate due to requiring specialized tools and unconventional angles
Solution Approach 1:
The patent merges the cleaning function directly into the nut structure by integrating bristles around the threaded bore. This combination allows the nut to simultaneously fasten and clean the threaded member, eliminating the need for separate cleaning tools and specialized angles, thereby improving accessibility while maintaining cleaning effectiveness
Solution Approach 2:
The nut is designed to perform multiple functions: fastening the threaded member and cleaning its external surface. This multi-functionality eliminates the need for specialized cleaning equipment, allowing standard nuts to serve dual purposes and improving ease of operation without sacrificing cleaning effectiveness
2Reliability
If specialized cleaning tools are used, then cleaning effectiveness is improved, but device complexity increases
Solution Approach 1:
The cleaning function is merged into the nut structure itself through integrated bristles, eliminating the need for separate specialized cleaning tools. This integration reduces device complexity by using a single component (the nut) to perform both fastening and cleaning functions
Solution Approach 2:
The nut serves as a universal component that performs both fastening and cleaning operations. This multi-functionality eliminates the need for multiple specialized tools, thereby reducing overall device complexity while maintaining effective cleaning capability
3Reliability
If additional tools are used for cleaning, then cleaning effectiveness is improved, but ease of operation deteriorates due to requiring additional equipment
Solution Approach 1:
The cleaning function is merged into the nut structure through integrated bristles, allowing the same component used for fastening to also perform cleaning. This eliminates the need for additional tools and simplifies the operational process while maintaining effective cleaning
Solution Approach 2:
The nut is designed as a universal component that performs both fastening and cleaning functions. This multi-functionality eliminates the need for additional equipment, thereby improving ease of operation and simplifying the overall process while ensuring effective cleaning

AI summary
A thread-cleaning tool comprises a partially hollow nut for use with a pneumatic, hydraulic, or electrical nut-running power tool. The nut comprises a plurality of brushes mounted in alignment with the outside corners of the nut, and facing inward to the central orifice of the nut, such that the nut abrasively removes corrosion and particulates from the threads of a shaft. In an embodiment, the brushes of the nut are mounted upon brush assemblies comprising rotating cam members, located in recesses spaced to align with the outer corners of the nut, providing a mechanism for the brushes to move back and forth as the nut is rotated up and down the thread. The brush assemblies can be easily removed or substituted as wear and tear accumulates.
