Adjustable Welding Carts with Sliding Rails for Gas Bottles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding carts designed for bulk gas delivery methods are inefficient for welders using individual gas bottles, as they occupy unnecessary space, making the carts longer than needed.
Innovation Solution
An adjustable welding cart that can transition between elongated and shortened configurations, accommodating both welding power supplies and gas bottles or power supplies alone, using adjustable rails and platforms to optimize space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the welding cart is configured to carry gas bottles/cylinders, then it can accommodate welders using individual gas bottles, but it makes the cart much longer than needed for welders using bulk gas delivery methods
Solution Approach 1:
The patent applies the dynamics principle by making the cart length adjustable rather than fixed. The cart includes telescoping sections with locking mechanisms that allow the length to be changed based on whether gas bottles are being transported. This enables the cart to adapt its configuration dynamically - extended when carrying gas bottles and retracted when using bulk gas delivery methods - thus resolving the contradiction between versatility and compactness.
Solution Approach 2:
The patent implements universality by designing the cart to serve multiple functions through its adjustable configuration. The same cart can accommodate both welders using individual gas bottles (by extending and positioning bottle holders) and welders using bulk gas delivery methods (by retracting to a compact configuration). This multi-functionality allows a single cart design to serve diverse welding scenarios without permanently compromising cart length for any one use case.
2Adaptability or versatility
If the cart is designed with fixed elongated configuration for gas bottles, then it can support gas bottles, but it reduces space efficiency when gas bottles are not used
Solution Approach 1:
The cart employs dynamic adjustability where the length and configuration of gas bottle support structures can be modified. When gas bottles are not being used, the telescoping sections are retracted and locking mechanisms secure the cart in a compact configuration, maximizing space utilization. When gas bottles need to be transported, the same structures are extended and positioned to provide adequate support, thus eliminating the need for permanently allocated space.
3Volume of moving object
If the cart is made adjustable to accommodate both configurations, then it can optimize space utilization, but it increases device complexity
Solution Approach 1:
The cart is divided into modular telescoping sections that can be independently adjusted and locked. Each section functions as a separate unit with its own locking mechanism, allowing for straightforward adjustment without requiring complex integrated systems. This segmentation simplifies the overall adjustment mechanism while enabling the cart to achieve multiple configurations for optimized space efficiency.

AI summary
Disclosed example adjustable welding carts include: a base having a front assembly and a rear assembly; the front assembly including: front wheels, a front support platform having a front end and a rear end, and two parallel rails, each rail having a front end fixedly attached to the front support platform; and the rear assembly including: rear wheels, a rear support platform having a front end and a rear end, and two rail channels opening proximate the front end of the rear support platform, each rail channel extending through the length of the rear support platform and configured to receive the rear end of one of the two parallel rails. The welding cart can transition between a plurality of different length configurations by adjusting the position of the rails with respect to the rail channels, including between configurations supporting a welding-type power supply with or without a gas bottle.
