Socket-to-Tube Mechanical Locking for Precise Bushing Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for locking a socket body in a tubular body result in structural changes due to high temperatures, leading to instability and imprecise positioning, and do not allow for exact alignment.
Innovation Solution
Deforming the tubular body to create connection points adjacent to the socket body, eliminating the need for a material connection and allowing for precise alignment and reinforcement, using a centering mandrel to press the tubular body and form connection points that block adjustment along the tubular body's axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the pipe body is deformed to create a connection point using heat and/or pressure, then a material-bonded connection is formed between the bushing body and the pipe body, but structural changes occur in the pipe body and/or bushing body leading to insufficient strength and stability
Solution Approach 1:
The patent replaces thermal and chemical bonding processes with a purely mechanical deformation process. A deformation tool mechanically deforms the pipe body to create a connection point that secures the bushing body through physical interlocking rather than material bonding, thereby avoiding heat- and pressure-induced structural changes while maintaining connection strength
Solution Approach 2:
Instead of heating and pressing the materials together to bond them, the patent inverts the approach by using controlled mechanical deformation to create a geometric interlocking structure. The connection is achieved through the shape change of the pipe body forming a mechanical lock around the bushing body, rather than through material fusion
2Strength
If high temperatures are applied at the connection point during welding, then a material-bonded connection is achieved, but structural changes result in insufficient strength and stability
Solution Approach 1:
The patent substitutes thermal energy with mechanical energy for creating the connection. A deformation tool applies localized mechanical force to deform the pipe body and form a connection point that secures the bushing body, completely eliminating the need for high temperatures and associated thermal damage to the materials
3Manufacturing precision
If the bushing body is positioned within the pipe body, then the bushing body can be secured, but precise positioning is not achieved and high tolerances exist
Solution Approach 1:
The patent incorporates a centering element on the deformation tool that performs preliminary positioning of the bushing body within the pipe body before deformation occurs. This preliminary centering action ensures accurate alignment and precise positioning, reducing tolerances and improving both manufacturing precision and connection reliability
Solution Approach 2:
The centering element acts as an intermediary between the deformation tool and the bushing body, facilitating precise positioning. This intermediary component ensures that the bushing body is correctly aligned and centered before the deformation process creates the secure connection, thereby achieving high positioning accuracy
