Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional additive injector is used, then material delivery to a single FCC unit is achieved, but the system cannot deliver materials to multiple FCC units
Solution Approach 1:
The additive injector system is designed with multiple outlets that can be coupled to multiple FCC units, allowing a single injector to perform multiple delivery functions. The system can selectively deliver materials to different FCC units through valve control, making the injector universal rather than unit-specific.
Solution Approach 2:
The system divides the material delivery capability into separate outlets, each capable of being directed to different FCC units. The valve assembly segments the flow paths, allowing independent control of material delivery to each connected FCC unit while maintaining a unified injector body.
2Adaptability or versatility
If material is delivered to multiple FCC units, then versatility is improved, but control and metering precision becomes more difficult
Solution Approach 1:
The system incorporates metering devices at each outlet that provide feedback on the amount of material being delivered to each FCC unit. This feedback mechanism allows the control system to monitor and adjust deliveries to maintain precise metering control across multiple units simultaneously.
Solution Approach 2:
The valve assembly provides dynamic control by allowing selective opening and closing of different outlets based on which FCC units require material delivery. This dynamic routing capability enables precise control over material distribution to multiple units, adjusting flow paths in real-time to maintain metering precision.
3Device complexity
If a single delivery system serves multiple FCC units, then system complexity is reduced, but the ability to control material ratios for each unit is compromised
Solution Approach 1:
The valve assembly enables dynamic routing of materials to different FCC units, allowing the system to be easily reconfigured for different delivery scenarios. Each outlet can be independently controlled to deliver appropriate material ratios to specific units, maintaining operational flexibility within a unified system architecture.
4Ease of operation
If conventional injectors are used for each FCC unit, then delivery control is simple, but the number of required systems increases
Solution Approach 1:
The invention merges multiple injector functions into a single additive injector system with multiple outlets. By combining the metering, storage, and delivery capabilities into one unified system that serves multiple FCC units, the overall number of separate systems required is reduced while maintaining individual delivery control through the valve assembly.
