Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional arc welding torch devices require time-consuming and costly disassembly for replacing the wire core, leading to potential incorrect assembly and increased risk of production errors due to blind assembly processes.
Innovation Solution
The implementation of a position signaling mechanism within the arc welding torch device that provides visual or perceptible signals for correct alignment and positioning of the guide element, allowing for external verification of the wire core and guide element's correct insertion, reducing the need for extensive disassembly and ensuring accurate assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the wire core is replaced by disassembling the rear end of the arc welding torch device, then the wire core can be replaced, but it requires time-consuming and costly disassembly and assembly processes
Solution Approach 1:
The device is divided into a housing and a separate closure element that can be independently removed. The guide element is further segmented to allow extraction through the closure element opening, enabling replacement without disassembling the entire housing structure.
Solution Approach 2:
The guide element is extracted through the closure element opening rather than requiring disassembly of the housing. This extraction path allows the wire core and guide element to be removed and replaced by simply removing the closure element, significantly reducing dismantling time.
2Ease of repair
If the wire core is replaced by disassembling the rear end of the arc welding torch device, then the wire core can be replaced, but it involves costly disassembly and assembly processes
Solution Approach 1:
The closure element is designed as a separate, easily removable component with an opening that provides direct access to the guide element. This segmentation simplifies the replacement process and reduces the complexity of assembly operations required.
Solution Approach 2:
The guide element is designed to be extractable through the closure element opening, which simplifies the replacement procedure. This extraction design reduces the complexity of assembly by eliminating the need for complex disassembly of the housing structure.
3Ease of operation
If the guide element is inserted blindly into the arc welding torch device, then the replacement process is simpler, but it cannot be verified whether the guide element is correctly positioned
Solution Approach 1:
A position signaling device is integrated into the closure element that provides visual feedback when the guide element is correctly positioned. This feedback mechanism allows operators to verify correct insertion without complex inspection procedures, maintaining ease of operation while eliminating information loss.
Solution Approach 2:
The position signaling device uses color changes or visual indicators to communicate the correct positioning of the guide element. This simple visual feedback system allows operators to quickly verify proper installation without requiring technical expertise or complex measurement tools.
4Measurement precision
If the position signaling means is arranged inside the arc welding torch device, then it can signal correct positioning, but it cannot be perceived from the outside
Solution Approach 1:
The position signaling device is merged with the closure element, which is removed together with the guide element. This combination allows the signaling mechanism to remain simple and internal while providing external visibility through the closure element opening, achieving both precise detection and external verification.
Solution Approach 2:
The closure element acts as an intermediary that provides a window or opening through which the position signaling device can be observed from the outside. This intermediary structure allows internal position detection to be visually verified externally without requiring the signaling device to be externally mounted.

AI summary
In order to create a way to better control and assess the correct assembly of a replaced wire core in an arc welding torch device with a consumable electrode, wherein the electrode is designed with a direction of movement from a rear end of the arc welding torch device to a front end of the arc welding torch device, in the area of which the electrode melts during an arc welding process, and wherein the electrode is guided in the arc welding torch device in a replaceable wire core, wherein the wire core is in turn arranged at least in the area of the rear end of the arc welding torch device in a guide element surrounding the wire core and designed as a replaceable wear part, wherein the guide element of the wire core is intended for the common replacement of the wire core due to wear, it is proposed thatthat a predetermined end position is provided for the guide element with regard to its insertion direction into the arc welding torch device, and that a position signaling device is perceptible outside the arc welding torch device when the guide element reaches the end position.
