Polygonal Threaded Pipe Clip Connection for Easier Tool Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe clamps require significant manufacturing effort due to the need for parallel flats on threaded connection parts for tool engagement, which complicates the attachment of threaded rods and sleeves.
Innovation Solution
The threaded connection part is made from a rod section forming a regular polygon, with external threads on the circumference and parallel sides serving as tool engagement surfaces, allowing for reduced manufacturing effort and secure attachment without rotational movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parallel flats are introduced on the threaded connection part for tool engagement, then the threaded rod or sleeve can be securely attached, but the manufacturing effort increases considerably
Solution Approach 1:
The patent combines the tool engagement surface and the threaded connection part into a single integrated component. The rod section with polygonal cross-section serves both as the structural element for the external thread and as the tool engagement surface, eliminating the need for separate parallel flats and reducing manufacturing steps
Solution Approach 2:
The rod section with polygonal cross-section performs multiple functions: it provides the structural base for the external thread, creates the tool engagement surface for wrench application, and maintains sufficient outer diameter for connection to threaded counterparts. This multi-functional design simplifies the overall structure and manufacturing process
2Adaptability or versatility
If the threaded connection part has a large outer diameter to accommodate internal threads, then it can connect to various threaded counterparts, but the tool engagement surface becomes more difficult to access
Solution Approach 1:
The patent transitions from a conventional cylindrical threaded connection part to a polygonal rod section. This dimensional change in the cross-sectional shape provides accessible parallel surfaces that are easier to engage with tools, while maintaining the necessary outer diameter for versatile connections to various threaded counterparts
