Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connecting devices for water-cooled welding torches often fail to ensure efficient cooling liquid circulation, prevent gas leaks, and allow for easy angular adjustment of pipe bends, while also being complex and costly to produce.
Innovation Solution
The design features a plug part with cooling channels' openings arranged externally and internally, a flange for angular adjustment, and a sliding ring for electrical conductivity, along with a socket part that closes cooling channels when disconnected to prevent liquid escape, allowing for easy handling and continuous cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cooling channels are arranged with both openings on the outside of the cylindrical tube element, then the connection structure is simpler, but the cooling liquid may short-circuit and flow back before reaching the cooling components
Solution Approach 1:
The cooling channels are segmented into different spatial locations: one opening on the outside and one on the inside of the cylindrical tube element. This segmentation prevents the cooling liquid from short-circuiting while maintaining a simple connection structure.
Solution Approach 2:
The openings of the cooling channels are positioned in different dimensional spaces (inside and outside of the tube element) rather than both on the same surface. This spatial arrangement ensures proper cooling liquid flow direction while keeping the connection simple.
2Ease of operation
If the pipe bend is made rotatable for angular adjustment, then the welding torch can be held at the optimum angle, but the cooling system must be switched off during position changes
Solution Approach 1:
The cooling channels are designed with separate inside and outside openings that maintain continuous cooling flow even during rotation. The cooling system is prepared in advance to handle rotational movements without requiring shutdown, eliminating the need for complex control operations.
Solution Approach 2:
The cooling liquid circulation maintains continuous action during pipe bend rotation. The specially arranged cooling channels ensure uninterrupted cooling flow, allowing the welding torch to be adjusted to optimal angles without switching off the cooling system.
3Device complexity
If conventional connecting devices are used, then the structure is simpler, but they fail to prevent cooling liquid escape and ensure efficient cooling circulation
Solution Approach 1:
The connecting device separates the cooling channel openings into inside and outside positions on the cylindrical tube element. This segmentation prevents cooling liquid escape while maintaining a relatively simple overall structure.
Solution Approach 2:
Different parts of the connecting device have specialized functions: the inside opening handles cooling liquid supply, while the outside opening manages return flow. This local differentiation ensures reliable cooling liquid containment without excessive structural complexity.
4Reliability
If the cooling channels are arranged with both openings on the inside of the cylindrical tube element, then short-circuiting is prevented, but the connection structure becomes more complex
Solution Approach 1:
Instead of placing both openings inside the tube element, the cooling channels are segmented with one inside opening and one outside opening. This segmentation achieves reliable cooling circulation while maintaining manufacturing simplicity.
Solution Approach 2:
The openings are positioned in different spatial dimensions (inside and outside) rather than both inside. This dimensional arrangement prevents short-circuiting while keeping the connection structure simple and manufacturable.
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
This solution ensures efficient cooling liquid circulation, prevents gas leaks, allows for flexible angular adjustment of pipe bends, and simplifies handling by maintaining continuous cooling without needing to switch off the cooling system during position changes.
Implementation Method 1
at least two cooling channels for the supply and return of a cooling liquid... the opening of one cooling channel being arranged on the outside of the cylindrical tubular element and the opening of the other cooling channel being arranged on the inside of the cylindrical tubular element... results in forced guidance of the cooling liquid in the plug part
Implementation Method 2
If necessary with a conductor for the transmission of electrical energy from the socket part to the plug part
