Engineering Contradiction Analysis
1Productivity
If combustion products are mixed with feedstock gas using conventional mixing methods, then the mixing process is simple, but the decomposition efficiency is suboptimal due to inadequate mixing
Solution Approach 1:
The patent employs dynamic injection strategies where multiple streams of combustion products are injected at different angles and velocities into the mixing chamber. The injection parameters (angle, velocity, timing) are dynamically adjusted to create optimal mixing conditions, transforming the static mixing process into a dynamic one that enhances decomposition efficiency while managing system complexity through controlled variability
Solution Approach 2:
The mixing system is segmented into multiple independent injection streams, each capable of being controlled separately. By dividing the combustion products into multiple streams injected at different angles, the system achieves more thorough mixing and improved decomposition efficiency without requiring a completely complex integrated system, as each stream can be optimized independently
2Stability of the object's composition
If multiple streams of second fluid are injected at intersecting angles to improve mixing, then the mixing efficiency is enhanced, but the device complexity increases
Solution Approach 1:
The patent merges multiple injection streams of combustion products into a single mixing chamber where they intersect and combine. By consolidating the mixing function into one chamber rather than requiring separate mixing devices for each stream, the system achieves homogeneous fluid composition while limiting the increase in overall device complexity through functional integration
Solution Approach 2:
The injection system utilizes angular dimensions by injecting streams at different angles into the mixing chamber. This dimensional approach to mixing—injecting from different directions rather than simply increasing flow rates—enhances mixing homogeneity without proportionally increasing device complexity, as the additional mixing capability is achieved through spatial arrangement rather than additional complex components
3Productivity
If combustion products are injected to generate vorticity for improved mixing, then the decomposition efficiency increases, but the energy consumption increases
Solution Approach 1:
The system utilizes the kinetic energy already present in the combustion products to generate vorticity and mixing action. By injecting the combustion products at appropriate angles and velocities, the system allows the fluid itself to create the mixing vortices without requiring additional energy input from external mixing devices, thus improving decomposition efficiency while minimizing additional energy consumption
Solution Approach 2:
The patent optimizes injection parameters such as angle, velocity, and timing to achieve effective vorticity generation with minimal energy input. By carefully adjusting these parameters, the system maximizes the mixing efficiency and decomposition rate while minimizing the energy required for injection, thereby improving productivity without proportionally increasing energy consumption

AI summary
A mixing chamber is loaded with a first fluid. While a volume of the first fluid within the mixing chamber is constant, first and second streams of a second fluid are injected into the mixing chamber along first and second injection directions. As a result of injecting the first and second streams of the second fluid into the mixing chamber, the first and second streams of the second fluid impinge one another so as to generate within the mixing chamber at least one further stream of the second fluid that mixes with the first fluid and that flows in a direction different to the first and second injection directions.
