Pivoting Wire Feeder Base for Stable Welding and Easier Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional welding systems, including wire feeders, are cumbersome and difficult to move due to their mass and fixed configurations, making them challenging to transport efficiently in portable settings.
Innovation Solution
The design incorporates a pivotable support base with reduced friction elements such as casters and rails, allowing the wire feeder to transition from a horizontal operational position to angled or upright positions for easier mobility and storage, enabling efficient movement and use in various welding applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the welding system uses a fixed base plate configuration, then the system provides stable support for welding operations, but the system becomes difficult to move and transport
Solution Approach 1:
The base plate is made pivotable relative to the wire feeder housing, allowing it to transition between a horizontal position (providing stability during welding) and an angled position (facilitating movement and storage). This dynamic configuration enables the system to adapt its stability characteristics based on operational requirements.
2Reliability
If the welding system has a relatively great mass, then the system provides sufficient weight for stable operation, but the system becomes difficult to transport around the job site
Solution Approach 1:
The pivotable base plate allows operators to tilt the wire feeder at an angle, enabling them to roll or slide the equipment more easily across surfaces. When not in use or during transport, the angled position reduces the effective contact area and facilitates movement, while during welding operations, the base can be positioned for stability.
3Adaptability or versatility
If the support base is in constant contact with the support surface, then the system provides maximum stability, but the system cannot be easily repositioned or stored in compact configurations
Solution Approach 1:
The pivotable base plate design allows the system to switch between different operational states: a horizontal position where the base plate contacts the support surface for stable welding operations, and an angled position where the base plate lifts off the surface for easy repositioning and compact storage. This dynamic positioning capability provides both adaptability and operational stability as needed.

Implementation Method 1
at least one reduced friction element extending from a second end of the support base so that the reduced friction element is out of engagement with a support surface when the support base is in the horizontal position and the reduced friction element is in engagement with the support surface when the support base is pivoted to an angled position
