Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional batch chemical synthesis processes are used, then large batch volumes can be processed, but considerable hold time between steps occurs and product loss increases
Solution Approach 1:
The patent implements continuous manufacturing processes where materials flow continuously through reaction, separation, and purification stages without batch interruptions. This eliminates hold times between steps while maintaining large-scale production capacity, directly resolving the contradiction between processing quantity and time loss.
2Productivity
If traditional continuous manufacturing sequences are used, then continuous operation is achieved, but the number of devices required is large and operational problems increase
Solution Approach 1:
The patent combines multiple functions into integrated continuous processing units. For example, reaction and separation operations are merged into continuous flow reactors with integrated separation stages, reducing the total number of discrete devices while maintaining continuous production capability and improving operational reliability.
Solution Approach 2:
The patent employs multi-functional continuous processing equipment that can perform multiple operations. For instance, continuous extraction units can handle both separation and purification functions, and continuous crystallization systems integrate growth and separation, thereby reducing device complexity while sustaining continuous manufacturing.
3Ease of manufacture
If traditional separation devices are used, then separation is achieved, but emulsion formation occurs and clogging problems arise
Solution Approach 1:
The patent replaces traditional mechanical separation devices (such as gravity settlers and filters) with membrane-based separation systems. Membranes provide separation through selective permeability rather than mechanical forces, eliminating emulsion formation and clogging issues while maintaining efficient separation and ensuring reliable continuous operation.
Solution Approach 2:
The patent utilizes membrane films as separation barriers in continuous processing. These thin film membranes provide selective transport of components without the mechanical complications of traditional separation devices, preventing emulsion formation and clogging while achieving effective separation, thereby improving both ease of manufacture and operational reliability.
