Adjustable Welding Cart Rails for Variable-Length Gas Bottle Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Welding carts designed for bulk gas delivery methods occupy unnecessary space when used by welders who prefer gas bottles, as they are not adjustable to accommodate both bulk gas delivery and gas bottles.
Innovation Solution
An adjustable welding cart that transitions between elongated and shortened configurations, allowing it to support either a welding power supply with or without a gas bottle, utilizing adjustable rails and rail channels with locks for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the welding cart is configured with fixed elongated structure to accommodate gas bottles, then gas bottle carrying capacity is improved, but cart length becomes excessive when gas bottles are not used
Solution Approach 1:
The patent applies the dynamics principle by making the cart structure adjustable between different length configurations. The cart includes movable sections with adjustment mechanisms that allow the overall length to be changed based on whether gas bottles need to be transported, thus resolving the contradiction between adaptability and excessive length.
Solution Approach 2:
The cart is divided into modular sections that can be independently adjusted or reconfigured. This segmentation allows the cart to be compact when gas bottles are not needed while maintaining the capability to extend for gas bottle transport, addressing both the adaptability and length concerns.
2Length of moving object
If the welding cart is configured with shortened structure for bulk gas delivery, then cart length is reduced, but inability to accommodate gas bottles reduces versatility
Solution Approach 1:
The adjustable length mechanism allows the cart to dynamically change its configuration from a shortened state for bulk gas delivery to an elongated state for gas bottle transport, thereby maintaining versatility while minimizing length when gas bottles are not required.
Solution Approach 2:
The cart is designed with multi-functionality through its adjustable structure, enabling it to serve both purposes: transporting gas bottles when needed and maintaining a compact form for bulk gas delivery scenarios, thus achieving universality across different welding operations.
3Ease of manufacture
If the welding cart has fixed configuration, then manufacturing simplicity is improved, but inability to adjust for different welding needs reduces adaptability
Solution Approach 1:
By dividing the cart into standardized modular sections with simple connection and adjustment mechanisms, the patent maintains manufacturing simplicity while enabling configuration flexibility. The modular design allows for easy assembly and adjustment without requiring complex manufacturing processes.

AI summary
An adjustable welding cart (10) includes: a base having a front assembly (30) and a rear assembly (40); the front assembly (30) including: front wheels (50), a front support platform (60) having a front end and a rear end, and two parallel rails (70), each rail having a front end fixedly attached to the front support platform; and the rear assembly (40) including: rear wheels (80), a rear support platform (90) having a front end and a rear end, and two rail channels (100) opening proximate the front end of the rear support platform, each rail channel (100) extending through the length of the rear support platform and configured to receive the rear end of one of the two parallel rails (70). The welding cart (10) 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.
