Telescoping Torch for Adjustable Reach and Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current welding and plasma torches have a fixed length, requiring users to switch between different torches for various tasks, leading to increased costs and space requirements due to the need for multiple torches of varying lengths.
Innovation Solution
A telescoping torch design that allows the length to be adjusted between an expanded and collapsed configuration, enabling the torch to be set to any desired length between these extremes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple torches of different lengths are used to complete a job, then task-specific performance requirements are met, but cost and space requirements increase
Solution Approach 1:
The torch incorporates a telescoping mechanism that allows the torch head housing to slide relative to the torch body housing, enabling dynamic adjustment of torch length. The torch can be extended to a longer configuration for tasks requiring reach and visibility, or retracted to a shorter configuration for tasks requiring maneuverability in tight spaces. This dynamic length adjustment eliminates the need for multiple fixed-length torches.
Solution Approach 2:
The telescoping torch design provides multi-functionality by enabling a single torch to perform multiple length-specific tasks. The torch head housing can be positioned at various extensions along the torch body, allowing the same torch to serve as both a short torch for corner work and a long torch for reach applications, thereby universalizing the tool for diverse welding and cutting tasks.
2Length of moving object
If a longer torch is used, then visibility and reach are improved, but maneuverability in tight spaces deteriorates
Solution Approach 1:
The torch employs a telescoping mechanism with a slidable torch head housing that can be extended or retracted along the torch body. When working in tight spaces, the torch head housing is retracted to provide a shorter, more maneuverable torch. When visibility and reach are needed, the torch head housing is extended to provide a longer torch, thus dynamically adapting the length to match the operational requirements.
3Ease of operation
If a shorter torch is used, then maneuverability and portability are improved, but reach and visibility deteriorate
Solution Approach 1:
The telescoping mechanism allows the torch to transition between short and long configurations. For tasks requiring maneuverability and portability, the torch head housing is retracted to create a compact, short torch that is easy to handle and navigate in confined areas. When reach and visibility become necessary, the torch head housing is extended to increase the effective length, thus dynamically resolving the trade-off between maneuverability and reach.
4Device complexity
If the torch length is fixed, then structural simplicity is maintained, but adaptability to different tasks deteriorates
Solution Approach 1:
The torch incorporates a telescoping mechanism with a slidable torch head housing that can be extended or retracted along the torch body, adding dynamic length adjustment capability. This mechanical addition allows the torch structure to transition from fixed to variable length, providing adaptability to different task requirements while maintaining relative structural simplicity through the use of a straightforward telescoping design.

AI summary
A torch having an adjustable length. The torch may include a first housing portion and a second housing portion. The second housing portion may be slidably coupled to the first housing portion. The second housing portion may be configured to slide along a longitudinal direction of the torch to adjust a length of the torch.
