Elastic Torch Tip Protector for Oxyacetylene Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oxyacetylene cutting torch tips are prone to clogging during transport due to exposure to dirt and debris, leading to inefficiencies and increased maintenance time, as existing protectors do not effectively seal the orifices during transport.
Innovation Solution
A torch tip protector with a disc-shaped base and truncated conical side wall that forms a cup-like shape to enclose the torch tip, secured by an elastic member and hook mechanism that engages with the gas lines, providing a secure and adjustable fit to accommodate temperature changes and potential debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the torch tip is left exposed during transport, then accessibility and ease of operation are improved, but the orifices become clogged with dirt and debris
Solution Approach 1:
A torch tip protector is provided that pre-covers the orifices before transport begins. The protector is attached to the torch tip in advance, creating a protective barrier that prevents dirt and debris from entering the orifices during transport and storage, eliminating the need for cleaning before use.
Solution Approach 2:
The torch tip protector acts as an intermediary element between the harmful external environment (dirt, debris) and the vulnerable torch tip orifices. This intermediate component allows the torch tip to remain protected during transport while maintaining full accessibility and ease of operation when the protector is removed or designed to be transparent.
2Object-affected harmful factors
If a torch tip protector is added, then protection from clogging is improved, but device complexity increases
Solution Approach 1:
The torch assembly is segmented into functional components: the torch tip, the protector, and the attachment mechanism. This segmentation allows the protector to be a separate, removable component that provides protection without permanently complicating the torch structure. The protector can be attached and removed as needed, maintaining simplicity of the core torch design.
Solution Approach 2:
The torch tip protector is designed to be universally compatible with various torch tip configurations. A single protector design can accommodate different torch tip sizes and shapes, reducing the need for multiple specialized protectors and thereby minimizing overall device complexity while providing comprehensive protection.
3Reliability
If the protector is securely attached, then reliability during transport is improved, but ease of removal and adjustment is worsened
Solution Approach 1:
The attachment mechanism incorporates dynamic elements such as elastic members (springs) that provide automatic tension and secure attachment during transport. The same elastic mechanism allows for easy release when needed, enabling the protector to transition from a securely attached state during transport to an easily removable state when the torch is in use, without requiring complex locking or unlocking procedures.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The protector effectively prevents clogging and damage to the torch tip during transport by maintaining a sealed environment, reducing maintenance time and ensuring consistent performance.

AI summary
A torch tip protector (10) is elastically retained to an oxyacetylene cutting torch tip (6) during transport. The torch tip protector in the preferred embodiment has a protector cap (12) having a generally disc-shaped base and a truncated conical side wall that together form a cup or thimble-shaped torch tip cover. This torch tip cover operatively encompasses a torch tip and thereby operatively blocks access and fouling of the torch tip. To ensure that the protector cap stays engaged with torch tip, a hook (16) secures to and is manually removable from at least one of the torch gas lines (4). A spring (15) couples to the hook and couples with the protector cap to provide an elastic tension force that draws the protector cap towards hook and thereby secures the protector cap onto the torch tip.
