Interlocking Fluid Line Straightener for Connector-Compatible Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid line straightening tools are complex and inconvenient, especially when dealing with preassembled connectors, and often result in irregular patterns or undesirable manipulation.
Innovation Solution
A hand tool with interlocking sections featuring recesses and projections forms an elongated tunnel for straightening fluid lines, with enlarged flanges for easy handling and multiple pressure points for alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing line straightening hand tools are used, then line straightening function is provided, but the tools tend to be complex and inconvenient to use
Solution Approach 1:
The tool is divided into two separate sections that can be assembled together. Each section has a simplified structure with recesses or projections for interlocking, making individual sections easier to manufacture and handle while combining to form the complete straightening tool
Solution Approach 2:
The tool design accommodates lines with or without preassembled connectors through the same basic tunnel structure, making the tool versatile for multiple line types and connector configurations without requiring different tool designs
2Manufacturing precision
If hand straightening is performed, then line straightening is achieved, but it results in an irregular pattern along the length
Solution Approach 1:
The tunnel interior features specific localized structures including ridges and grooves positioned at predetermined locations along the tunnel length. These local features provide controlled pressure points that guide the line through the tunnel, ensuring uniform bending patterns and consistent straightening results
Solution Approach 2:
The tunnel structure acts as an intermediary between the user's manual force and the line being straightened. By channeling the pulling force through the structured tunnel with its ridges and grooves, the tool mediates the straightening process to produce uniform patterns rather than irregular manual manipulation
3Adaptability or versatility
If existing tools are used with preassembled connectors, then line straightening is attempted, but the tools are inconvenient to use
Solution Approach 1:
The tunnel structure is designed to accommodate lines with preassembled connectors by providing sufficient length and appropriate internal geometry. The same basic tool structure works for both connected and unconnected lines, making it universally adaptable without requiring different tool versions
Solution Approach 2:
The tool includes features such as enlarged flanges at the ends that facilitate preliminary positioning and handling. These features prepare the line and connector assembly for straightening by providing hand abutment surfaces and alignment features before the actual straightening force is applied

AI summary
A hand tool for straightening a fluid line has two sections that are configured to interlock and define an elongated line straightening channel between ends of the tool. One tool section has recesses and the other tool section has projections. The hand tool is assembled by moving the two sections together and interlocking the projections and recesses to form a tubular configuration or tunnel that straightens the line.
