Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If vacuum pump or jet vacuum tube is used, then vacuum pressure can be generated, but energy consumption is huge
Solution Approach 1:
The patent replaces the mechanical vacuum pump system with a chemical combustion system. Instead of using motors, blades, or screws to create vacuum mechanically, the invention uses fuel combustion to directly heat the cavity and generate vacuum through thermal expansion and contraction of gas, eliminating the need for complex mechanical energy conversion chains.
Solution Approach 2:
The invention changes the working parameter from mechanical energy input to thermal energy input. By controlling the temperature parameter through combustion, the system achieves vacuum generation through thermal processes rather than mechanical processes, fundamentally changing the energy conversion pathway.
2Object-affected harmful factors
If vacuum pump or jet vacuum tube is used, then vacuum can be produced, but noise is huge
Solution Approach 1:
The patent replaces noisy mechanical components (motors, rotating blades, high-speed fluid jets) with a quiet chemical combustion process. The combustion chamber operates without moving parts that generate noise, and the vacuum generation occurs through controlled thermal processes rather than high-velocity mechanical or fluid dynamics.
3Productivity
If traditional flame method (cupping) is used, then vacuum can be formed, but the process is slow and cannot produce high vacuum
Solution Approach 1:
The patent applies local quality by concentrating the combustion process in a specific chamber region and using a fuel replenishment unit to ensure continuous fuel supply at the combustion zone. This localized intensive combustion generates rapid heating and more effective vacuum generation compared to distributed or weak flame sources.
Solution Approach 2:
The invention implements continuity of useful action through the fuel replenishment unit that continuously supplies fuel to maintain sustained combustion. This continuous combustion process ensures rapid and consistent vacuum generation, eliminating the intermittent or slow heating characteristic of traditional methods.

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 solution achieves low energy consumption, wide operational flexibility, and reduced noise by directly converting fuel into vacuum pressure with minimal energy loss and no need for high-power electrical equipment, enabling rapid and high vacuum pressure generation.
Implementation Method 1
the igniter is configured to ignite the combustible object, the combustible object generating a flame in the cavity
Implementation Method 2
the cavity is in communication with the outside atmosphere only when the pressure in the cavity is greater than a pressure outside the shell

AI summary
The present disclosure discloses a flamed-based vacuum generator, including a shell and a combustion assembly, where the shell has a cavity, the cavity being a space having at least one opening, and the combustion assembly includes a combustible object and an igniter, the igniter being configured to ignite the combustible object, the combustible object generating a flame in the cavity, and the flame extinguishing in the cavity. In the present disclosure, through in-depth study of the internal mechanism of vacuum generated by flame combustion, it is found that the extinguishing process of a flame is the key to the generation of vacuum, and a larger flame and more sufficient combustion indicate a higher vacuum pressure generated in the cavity after the flame is extinguished.
