Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a sequential transfer and storage system is used, then the reagent preparing device can store reagents, but the amount of reagent prepared within a predetermined time is limited
Solution Approach 1:
The reagent preparing device is divided into multiple independent mixed solution containers (first mixed solution container and second mixed solution container), each capable of preparing reagents simultaneously. This segmentation allows parallel processing of reagent preparation, doubling the productivity within the same time frame without increasing the sequential transfer time.
Solution Approach 2:
The system transitions from a single-container sequential preparation model to a multi-container parallel preparation model, adding the dimension of parallelism. By operating multiple containers simultaneously, the system increases the total amount of reagent prepared within a predetermined time while maintaining the same operational complexity per container.
2Productivity
If a single mixed solution container is used, then the device structure is simple, but the reagent preparation capacity is limited
Solution Approach 1:
The system divides the reagent preparation function into multiple identical modular units (first and second mixed solution containers), each with its own diaphragm pump and control mechanisms. This modular segmentation increases preparation capacity while keeping each individual unit simple and standardized, making the overall system scalable and manageable.
Solution Approach 2:
Each mixed solution container is designed as a universal module that can independently perform the complete reagent preparation function. The diaphragm pumps and control units in each container are identical and can operate autonomously, allowing the system to scale by simply adding more identical modules without designing new complex subsystems.
3Productivity
If sequential supply of reagents is used, then the control mechanism is simple, but the reagent supply efficiency is low
Solution Approach 1:
The control unit implements periodic alternating supply between the first and second mixed solution containers. The control mechanism cycles through supply operations in a regular sequence, switching between containers in a predetermined rhythm. This periodic action increases supply efficiency by keeping both containers operational while maintaining a simple, predictable control pattern that does not require complex real-time decision-making.
