Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automated sampling devices are used, then sampling accuracy and automation are improved, but device complexity increases
Solution Approach 1:
The device is divided into modular components: a container for reagent storage, a dosing apparatus with spiral rod for sampling, and a connector structure with sealing rings for connection. This segmentation allows each component to perform its function independently while simplifying the overall system design and reducing complexity.
Solution Approach 2:
The connector structure serves multiple functions: it connects the container opening to the dosing apparatus, provides sealing through integrated sealing rings, and enables automated operation. This multi-functionality reduces the need for separate components, thereby simplifying the device while maintaining automation.
2Device complexity
If manual weighing and sampling operations are performed, then device complexity is reduced, but measurement precision and reliability deteriorate
Solution Approach 1:
The dosing apparatus with spiral rod automatically performs the sampling and weighing operations without manual intervention. The spiral rod rotates to convey reagent from the container through the connector structure, enabling automated precise dosing while maintaining simple device architecture.
3Device complexity
If manual handling operations are performed, then device complexity is reduced, but reagent loss and contamination increase
Solution Approach 1:
The connector structure with integrated sealing rings acts as an intermediary between the container and dosing apparatus, providing sealed connection that prevents reagent leakage and contamination during automated transfer. This eliminates the need for manual handling while maintaining simple device design.
4Device complexity
If manual handling operations are performed, then device complexity is reduced, but reagent contamination increases
Solution Approach 1:
The connector structure with integrated sealing rings acts as an intermediary between the container and dosing apparatus, providing sealed connection that prevents reagent leakage and contamination during automated transfer. This eliminates the need for manual handling while maintaining simple device design.

AI summary
A dosing equipment, including: a container; a dosing apparatus, at least partially provided within the container and connecting with an interior and an exterior of the container to convey the reagent from the interior of the container to the exterior of the container; a connector structure connecting the container opening and the dosing apparatus. The connector structure includes a connector penetrating along the axial direction of the container opening, a support member and a bearing member sequentially socketed within the connector. The connector is socketed on an outer periphery of the container opening, and a gap exists between the connector and the support member to receive a sidewall of the container opening. The bearing member is provided outside the dosing apparatus. A first sealing ring and a second sealing ring are provided to seal-connect the connector structure, the dosing apparatus, and the container opening, respectively.
