Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid oxygen (LOX) systems for torch cutting are bulky, heavy, and limited in transportation due to their large size and low flow rates, making them unsuitable for high-volume, rapid exothermic cutting operations in industrial and tactical environments, where extended cutting times and mobility are critical.
Innovation Solution
A modular and transportable LOX exothermic cutting device comprising liquid oxygen containers, vaporizers, and a cutting torch, with a parallel dual liquid oxygen combining valve, flow modulators, and an oxygen gas pressure regulator, allowing for high-volume flow rates and ease of transportation, including stackable frames to dampen vibrations and support multiple LOX supply units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional compressed gas cylinders are used for torch cutting, then portability is improved, but cutting duration is limited and multiple bulky cylinders are required
Solution Approach 1:
The patent changes the physical state of oxygen from compressed gas to liquid form, dramatically increasing storage density. This allows extended cutting duration while maintaining portability, as liquid oxygen occupies much less volume than compressed gas cylinders.
Solution Approach 2:
The system divides the oxygen supply into modular liquid oxygen containers that can be stacked or configured in arrays. This segmentation allows flexible scaling of cutting duration while maintaining the portability advantage of smaller individual units.
2Duration of action of moving object
If industrial LOX tanks are used to extend cutting time, then cutting duration is improved, but transportation to remote locations becomes nearly impossible
Solution Approach 1:
The patent divides large industrial LOX tanks into multiple smaller, modular liquid oxygen containers. These smaller units can be transported to remote locations using standard vehicles, then combined to achieve the desired cutting duration, thus resolving the transportability issue while maintaining extended operation capability.
Solution Approach 2:
The system transitions from a single large-volume tank to a modular array of smaller containers that can be stacked vertically or arranged in configurations suitable for transport. This dimensional reorganization maintains total oxygen capacity while improving transportability to remote locations.
3Duration of action of moving object
If existing LOX packages are used, then extended cutting is possible, but flow rates are limited to low consumption functions
Solution Approach 1:
The patent merges multiple liquid oxygen container outputs into a single high-volume flow system. By combining the output from multiple modular containers through a common vaporizer and delivery system, the system achieves both extended cutting duration and high flow rates necessary for rapid exothermic cutting operations.
Solution Approach 2:
The system performs preliminary vaporization of liquid oxygen in dedicated vaporizer units before delivery to the torch. This preliminary action ensures that high-volume flow requirements are met at the point of use, enabling rapid cutting operations while the liquid oxygen containers continue to supply extended duration.
4Productivity
If modular LOX system with multiple supply units is used, then high-volume flow rate is achieved, but system complexity increases
Solution Approach 1:
The patent segments the complex high-volume flow system into identical, modular container-vaporizer units. Each module is self-contained and interchangeable, reducing operational complexity despite the increased number of components. The modular design allows systematic assembly and maintenance while achieving high-volume flow rates.
