Thread Cleaning Tool With Integrated Surface Grinding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cleaning concrete residue from threaded bolts in the construction industry are time-consuming, labor-intensive, and result in inconsistent quality, requiring separate tools for thread cleaning and surface grinding.
Innovation Solution
A tube-structured thread cleaning device with a scraping action and a brushing action, powered by a portable power tool, which can be inserted over a fixed thread to clean debris and grind the surrounding surface flat in a single operation, with replaceable cleaning and abrading components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a worker uses a spinning wire wheel or brush attached to a portable drill to clean threaded studs, then the threads can be cleaned, but the process is time-consuming and labor-intensive
Solution Approach 1:
The patent combines multiple cleaning functions (brushing, scraping, and surface grinding) into a single integrated device that can be attached to a power tool. The device merges a brush section for cleaning threads, a scraper section for removing concrete, and an abrasive section for grinding surfaces, allowing all operations to be performed simultaneously in one positioning action rather than requiring separate tools and operations.
Solution Approach 2:
The cleaning device is designed as a multi-functional tool that can perform thread cleaning, concrete scraping, and surface grinding operations. The universal design allows a single device to replace multiple specialized tools (wire wheel brush, scraper tool, and grinding disc), enabling one worker to accomplish tasks that previously required multiple tools and sequential operations.
2Reliability
If separate tools are used for thread cleaning and surface grinding, then each function can be performed adequately, but the overall process becomes more complex and time-consuming
Solution Approach 1:
The patent integrates three distinct cleaning and grinding functions into a single device structure. The brush section, scraper section, and abrasive section are combined in one assembly that attaches to a power tool, reducing the number of separate tools from three to one while maintaining the reliability of each individual function through dedicated components.
Solution Approach 2:
The device serves multiple functions simultaneously - cleaning threads, scraping concrete, and grinding surfaces - all through one universal tool. This multi-functionality reduces device complexity by eliminating the need to switch between multiple specialized tools while ensuring consistent quality through dedicated sections for each function.
3Manufacturing precision
If a handheld grinder with an abrasive disc is used to grind surface high spots, then the surface can be flattened, but the operation is time-consuming and results in inconsistent quality
Solution Approach 1:
The patent combines surface grinding functionality with thread cleaning operations in a single device. The abrasive section with a grinding disc is integrated into the same assembly that cleans threads, allowing surface flatness correction to occur simultaneously with thread cleaning when the device is positioned over the stud, eliminating the need for a separate surface grinding operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device efficiently cleans threaded bolts and grinds surrounding surfaces flat, significantly reducing time and effort while ensuring consistent quality, and allows for adaptation to different sizes and conditions through replaceable components.
Implementation Method 1
possess an abrasive surface oriented perpendicular to the pointed protrusions and bristles, to grind the area surrounding the stud flat
Implementation Method 2
a second section comprising an internal wire wheel structure with bristles pointing inward. The inside diameter of the bristles may be smaller than the outside diameter of the threaded stud. This section may clean the debris from the inside of the threads
Implementation Method 3
The pointed protrusions may scrape, break up, and loosen the concrete, leaving some remnant of the loose debris inside the threads

AI summary
A thread cleaner comprising an elongated body with a drive end and an open end, with an abrasive section, a scraper section, and a brush section at the open end, the scraper section intermediate the abrasive section and the brush section, the scraper section, and brush sections oriented to apply radial scraping and brushing force to an elongated workpiece positioned in alignment with the thread cleaner's central axis, and the abrasive section oriented to apply abrasive force perpendicular to the thread cleaner's central axis to a surface workpiece.
