Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If complex mixing devices using Venturi effect are used, then mixing efficiency is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The mixing device is segmented into a simple hollow body with multiple internal partitions that divide the flow into multiple streams. This segmentation creates effective mixing through flow division rather than complex Venturi structures, resolving the contradiction between mixing efficiency and device complexity
Solution Approach 2:
The invention changes the flow parameters by dividing the main flow into multiple secondary flows through internal partitions. This parameter change (flow division) achieves effective mixing without requiring complex device structures, thus resolving the technical contradiction
2Productivity
If complex mixing devices are used, then mixing efficiency is improved, but manufacturing cost increases
Solution Approach 1:
The device uses simple internal partitions dividing the hollow body into multiple chambers, which is much easier to manufacture than complex Venturi structures. This segmentation approach maintains mixing efficiency while significantly reducing manufacturing complexity and cost
Solution Approach 2:
The invention employs simple, inexpensive materials and structures (hollow body with partitions) that can be easily manufactured and replaced if needed, reducing both initial manufacturing cost and long-term maintenance costs while maintaining effective mixing performance
3Device complexity
If simple injection devices are used, then device complexity is reduced, but mixing efficiency decreases
Solution Approach 1:
The hollow body contains multiple internal partitions that divide the flow into multiple secondary streams. This internal segmentation transforms a simple external structure into an effective mixing device by creating multiple flow paths that enhance mixing efficiency
Solution Approach 2:
The invention adds the dimension of internal flow division within the hollow body. By creating multiple chambers and flow paths inside the simple external structure, it achieves effective mixing without increasing external complexity, resolving the contradiction between simplicity and efficiency
4Manufacturing precision
If complex mixing devices are used, then mixing homogeneity is improved, but interchangeability becomes difficult
Solution Approach 1:
The modular segmented structure with standardized hollow body and internal partitions allows for easy interchangeability between different engine configurations while maintaining consistent mixing homogeneity through the standardized design
Solution Approach 2:
The simple hollow body design with internal partitions serves multiple functions (flow division, mixing chamber, diffusion area) and can be universally applied to different engine types and configurations, enhancing interchangeability while maintaining mixing effectiveness

AI summary
The distributor (10) has a piece forming an injection and diffusion device (1) and including an elongated hollow body (4) with a separation wall or wing (6). The piece is mounted in a lateral opening (5) of an air delivering conduit segment (2) and projects inside an interior volume defined by the segment while being exposed to flow of a fresh air. The wall or wing divides injected flow of an exhaust gas recirculation gas and flow of the air into two respective secondary flows. The body has an open cover (4') authorizing contact and mixing between the air and the gas.
