Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single reception base with a distribution circuit is used to connect multiple ejectors, then the number of ducts is reduced and ejector replacement is facilitated, but the base can only accommodate a predefined number of ejectors and requires a larger capacity base when expansion is needed
Solution Approach 1:
The system is divided into independent modular units, each consisting of an ejector and its own individual base with integrated distribution circuit. This segmentation allows each module to function independently while maintaining simplicity of the overall system architecture.
Solution Approach 2:
The system transitions from a static, fixed-capacity base to a dynamic, expandable configuration where modules can be easily added or removed. The standardized interfaces enable the system to adapt its size and capacity based on operational requirements.
2Ease of operation
If individual feed ducts are connected to each ejector, then each ejector can be independently supplied with compressed air, but the compressed air feed circuit becomes more complicated and voluminous
Solution Approach 1:
The distribution circuit is merged with the base structure, integrating the compressed air distribution function into the module housing. This eliminates the need for separate external ducting for each ejector while maintaining independent supply capability.
Solution Approach 2:
Each module is self-contained with its own integrated distribution circuit, allowing it to independently manage its compressed air supply without requiring complex external routing or intervention from other system components.
3Adaptability or versatility
If a larger capacity base is acquired to accommodate more ejectors, then the system can be upgraded, but the initial investment and system complexity increase
Solution Approach 1:
The system uses segmented modular bases that can be individually configured for specific applications. Rather than requiring a large centralized base, the system divides functionality across multiple smaller, standardized modules that can be combined as needed.
Solution Approach 2:
The standardized base design serves multiple functions: it provides structural support, houses the distribution circuit, and offers mounting interfaces for ejectors. This multi-functionality reduces the need for additional components when expanding system capacity.

AI summary
A fluid flow device including a plurality of fluid flow functional modules each fastened on a respective individual base includes: two parallel lateral faces via which the bases are adapted to be placed against one another; a primary channel passing through the base to open out in its two lateral faces; a front face along which the module extends so as to couple an inlet channel of said module with a secondary channel extending in the base; a check valve closing the secondary channel when the base is not provided with a module; and a top face in which there extends a tertiary channel opening out in the primary channel. The device further includes a fastener for fastening the bases to one another, leaktight couplers for coupling the primary channel and the tertiary channel to a source of fluid under pressure.
