Pivotable Torch Cradle for Plasma Cutting Path Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for guiding hand-held torches, such as plasma torches, during cutting operations require manual adjustment and recalibration after disengagement from the cutting material, leading to inefficiencies and inaccuracies in cutting paths.
Innovation Solution
A torch guide device featuring a pivotable cradle assembly coupled to a rail assembly, which allows for adjustable orientation and automatic re-engagement of the torch tip relative to the cutting material, utilizing a motor-driven linear movement system and a laser guide for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual guidance of torch by hand is used, then ease of operation is improved, but manufacturing precision deteriorates
Solution Approach 1:
A guide attachment with a positioning element is introduced as an intermediary between the user's hand and the torch. The positioning element engages with reference features on the workpiece to mediate the torch's position and orientation, enabling precise cutting paths while maintaining manual operability.
2Ease of operation
If torch tip disengages from cutting material, then ease of operation is improved (can reposition), but manufacturing precision deteriorates (requires resetting position)
Solution Approach 1:
The guide attachment's positioning element automatically re-engages with the reference features on the workpiece when the torch is repositioned. This self-service mechanism ensures that the torch tip returns to the correct relative position and orientation without requiring manual resetting, maintaining both operational flexibility and cutting precision.
3Manufacturing precision
If guide attachment with positioning element is used, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The guide attachment is segmented into distinct functional components: a positioning element for engaging reference features, a support structure for holding the torch, and a guide element for maintaining orientation. This segmentation allows each component to perform its specific function efficiently while keeping the overall device relatively simple.

AI summary
A torch guide device for cutting target material is presented, the torch guide device including a torch cradle assembly coupled to a rail assembly. The torch cradle assembly is configured for holding a torch to align a torch tip of the torch to the target material. The torch cradle assembly is movable along the rail assembly for cutting the target material along a cutting path. The connector member couples the torch cradle assembly to the rail assembly. The connector member comprises a pivot for pivoting the torch cradle assembly relative to the rail assembly. The torch cradle assembly, in a first position, pivots about the pivot to engage at least a portion of the rail assembly to establish an orientation of the torch tip relative to the target material.
