Pipe De-burring Assembly with Dual Bristle Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing de-burring devices are inefficient in simultaneously de-burring the inside and outside surfaces of pipes and pipe fittings, particularly for copper plumbing components with diameters less than 2.0 inches, as they lack a comprehensive solution for effective surface smoothing.
Innovation Solution
A de-burring device comprising a cylinder with rotatably coupled shafts and bristles that frictionally engage both the inside and outside surfaces of pipes and fittings, utilizing a power tool to rotate the cylinder and bristles for simultaneous de-burring of both surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional de-burring devices are used, then only one surface (inside or outside) can be de-burred at a time, but this requires multiple tools and steps reducing efficiency
Solution Approach 1:
The patent combines multiple de-burring functions into a single integrated device. The cylinder assembly incorporates both internal bristles (for inside surface de-burring) and external bristles (for outside surface de-burring), allowing simultaneous de-burring of both surfaces of pipe fittings in one operation, thereby eliminating the need for multiple separate tools and steps
Solution Approach 2:
The de-burring device is designed with universal functionality to handle both inside and outside surfaces of pipe fittings. The cylinder can be configured with different bristle arrangements to accommodate various de-burring needs, making it a multi-functional tool that replaces several specialized tools with one versatile device
2Manufacturing precision
If separate de-burring operations are performed for inside and outside surfaces, then each surface receives adequate attention, but the process time increases
Solution Approach 1:
The device enables continuous de-burring action on both inside and outside surfaces simultaneously. As the cylinder rotates, both the internal bristles and external bristles continuously engage their respective surfaces, eliminating idle time between operations and maintaining continuous useful action throughout the de-burring process
Solution Approach 2:
The device performs preliminary de-burring action on both surfaces before the fitting is installed. By pre-smoothing both inside and outside surfaces in one operation, the device prepares the fitting for optimal installation without requiring subsequent separate de-burring steps, thus saving time while ensuring quality
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 effectively de-burs both the inside and outside surfaces of pipes and fittings, enhancing the smoothing process and ensuring proper fitting without the need for multiple tools or steps, thereby improving efficiency and precision.
Implementation Method 1
A plurality of first bristles is each of the first bristles coupled to the shaft and each of the first bristles frictionally engages an inside surface of the pipe fitting for de-burring the inside surface of the pipe fitting. A plurality of second bristles is each coupled to the cylinder and each of the second bristles frictionally engages an outside surface of the pipe to de-burr the outside surface of the pipe.
