Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If medicines are mixed using conventional dual-syringe systems, then mixing can be achieved, but storage safety is low and operation is inconvenient
Solution Approach 1:
The device separates the storage and mixing functions by providing separate vials for different medicines rather than storing them together in a syringe. Each medicine remains in its own sealed vial until mixing is required, maintaining storage safety while enabling convenient mixing through the connection mechanism.
Solution Approach 2:
The connection port and docking connector serve as an intermediary mechanism that enables mixing without requiring direct handling of the medicines. The syringe connects to the connection port, which in turn connects to both vials, allowing medicines to be mixed through this intermediary interface rather than requiring direct syringe manipulation of multiple vials.
2Productivity
If medicines are mixed using conventional methods, then mixing can be performed, but the process is complex and time-consuming
Solution Approach 1:
The device merges multiple functions into a single integrated structure: the connection port combines the functions of connecting to both vials and interfacing with the syringe, while the docking connector integrates the attachment and rotation functions. This reduces the number of separate operations required compared to conventional dual-syringe systems.
Solution Approach 2:
The connection port serves multiple functions simultaneously: it provides a sealed interface for the syringe, connects to both the first and second vials through the docking connector, and enables both mixing and extraction operations. This multi-functionality simplifies the overall process by eliminating the need for multiple separate devices or complex manipulation steps.
3Reliability
If medicines are mixed using conventional methods, then mixing can be achieved, but there are risks of contamination and infection
Solution Approach 1:
The invention extracts the mixing process from the storage containers by using separate sealed vials that remain closed during storage. The medicines are only exposed to the external environment through the controlled connection port interface during mixing, minimizing contamination risks while maintaining operational simplicity.
Solution Approach 2:
The sealed vial system creates a protected environment for the medicines throughout storage and mixing. The connection port and docking connector maintain sealed connections during the mixing process, effectively creating a controlled atmosphere that prevents contamination and infection risks associated with conventional open mixing methods.
