One-Piece Capsule for Two-Phase Mixture Propulsion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-phase mixture propulsion devices for fire extinguishing and cooling are cumbersome, heavy, and require complex maintenance due to numerous modules and pipes, making them less suitable for mobile applications.
Innovation Solution
A compact device design where the first and second modules form a one-piece capsule, eliminating the need for pipes and conduits, resulting in reduced weight, simplified maintenance, and increased reliability, with the capsule serving as a unified container for the liquid and gas components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple modules and pipes are used to propel two-phase mixture, then the device can achieve fire extinguishing and cooling functions, but the device becomes heavy and complex
Solution Approach 1:
The patent combines multiple separate modules (gas injection module, liquid injection module, mixing module) into an integrated capsule structure. The first and second modules are formed as a single piece that can be joined to the cavity inlet and outlet, eliminating the need for separate pipes and connectors between these components. This merging reduces the overall device weight while maintaining the fire extinguishing and cooling functions.
Solution Approach 2:
The capsule structure serves multiple functions simultaneously: it acts as a containment vessel for both gas and liquid, provides injection pathways for both phases, facilitates mixing of the two-phase mixture, and serves as a structural component that can be joined to the cavity. This multi-functionality reduces the number of separate components needed, thereby reducing weight.
2Reliability
If multiple modules and pipes are used to propel two-phase mixture, then the device can achieve fire extinguishing and cooling functions, but the device requires extensive maintenance
Solution Approach 1:
By merging the first and second modules into a single-piece capsule structure, the patent eliminates multiple pipe connections and joints between modules. Fewer connections mean fewer potential failure points and significantly reduced maintenance requirements, as there are no pipes or couplings to inspect, tighten, or replace during maintenance operations.
Solution Approach 2:
The capsule is designed as a removable unit that can be joined to and separated from the cavity inlet and outlet. This segmentation allows the capsule to be easily removed and replaced as a single unit during maintenance, rather than requiring disassembly of multiple connected components. The capsule can be detached as one piece for straightforward replacement.
3Reliability
If multiple modules and pipes are used to propel two-phase mixture, then the device can achieve fire extinguishing and cooling functions, but the device size increases
Solution Approach 1:
The patent merges the gas injection module, liquid injection module, and mixing module into a single integrated capsule structure. This consolidation eliminates the volume occupied by separate pipes, connectors, and individual module housings. The merged structure allows components to be arranged more compactly, reducing the overall device volume while maintaining all necessary functions for two-phase mixture propulsion.

Implementation Method 1
a piston (P) which under the action of the gas at the inlet (ECA) moves and allows by mechanical thrust the ejection of the liquid (L) towards the inlet (E22) of the second mixing module (T)
Implementation Method 2
the first and the second modules form a one-piece capsule which can be joined together (for example pluggable/screwable/etc.) on the inlet and the outlet of the cavity
