Elastomeric Torch Tip Cover Prevents Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oxyacetylene cutting torch tips are prone to clogging when not in use, especially in outdoor environments, due to lack of a secure and clean resting place, leading to issues with heat retention, bulkiness, and potential contamination of protective covers made from rigid materials.
Innovation Solution
A conical-shaped protective cover made from elastomeric material that frictionally engages with the torch tip, allowing easy installation and removal, heat resistance, and the ability to be stored in a pocket, featuring a distinctive color for easy retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid metal tip protector is used, then the torch tip is protected from contamination, but the protector retains heat and becomes bulky and unsafe to store
Solution Approach 1:
The patent applies this principle by using a flexible elastomeric material (such as rubber or silicone) to create a thin-walled tip protector that does not retain heat like rigid metal protectors. The flexible material allows the protector to conform to the torch tip while remaining thermally insulating, solving the heat retention problem.
Solution Approach 2:
The patent uses composite construction by combining an elastomeric outer material with an internal reinforcement structure (such as a wire mesh or structural framework) to provide both flexibility and structural integrity. This allows the protector to be thin-walled and heat-resistant while maintaining its shape and protective function.
2Reliability
If a loose fitting metal tip protector is used, then the torch tip is protected, but the protector can become ensnared with the work piece and is not securely held
Solution Approach 1:
The patent applies this principle by designing the elastomeric tip protector to self-grip the torch tip through elastic friction. The flexible material naturally conforms to and grips the tip contours without requiring external fastening mechanisms, hooks, or springs. This self-gripping action provides secure engagement while maintaining ease of installation and removal.
3Reliability
If a rigid metal tip protector is used, then the torch tip is protected, but the protector is bulky and cannot be conveniently stored in a pocket
Solution Approach 1:
The patent applies this principle by using a flexible elastomeric material to create a thin-walled tip protector that can be collapsed or compressed to a small size for storage. The flexible material allows the protector to be folded or rolled into a compact form that fits easily in a pocket, unlike rigid metal protectors that maintain their full volume.
Solution Approach 2:
The patent applies this principle by designing the tip protector to be nestable or collapsible into a compact configuration for storage. The flexible elastomeric construction allows the protector to be folded or compressed into a small package that can be stored in a pocket or small container, yet still provides full protection when deployed.
4Ease of operation
If the torch tip is placed on the ground when not in use, then the torch is stable, but the tip orifices become clogged with dirt and debris
Solution Approach 1:
The patent applies this principle by providing a protective cover that can be placed over the torch tip before the torch is set down. This preliminary protective action prevents contamination of the orifices before they can be clogged by dirt or debris on the ground or work surface.
Solution Approach 2:
The patent applies this principle by using a flexible elastomeric protective cover that can be easily placed over the torch tip when not in use. The flexible material conforms to the tip shape and provides a barrier against contamination, while being simple to install and remove.
Applied Scientific Principles
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 elastomeric torch tip cover effectively prevents clogging, maintains functionality by staying cool, and ensures easy storage and retrieval, addressing the limitations of prior solutions like loose metal protectors that retain heat and are bulky.
Implementation Method 1
a generally conical shaped cover formed of elastomeric material and configured for elastic frictional engagement with said cutting torch tip
Implementation Method 2
it should be flexible and resistant to heat absorption so that it could be safely stored in a shirt or trouser pocket
