Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual inversion mixing is performed after dispensing solvent into freeze-dried reagent, then dissolution accuracy is improved, but labor effort and time consumption increase
Solution Approach 1:
The reagent container is designed to perform self-mixing through its own rotation and tilting movements. The container rotates around its central axis and simultaneously tilts at a predetermined angle, creating automatic inversion mixing without requiring external manual intervention. This self-service mechanism eliminates the need for users to manually invert and mix the reagent, thereby reducing labor effort and time consumption while maintaining dissolution accuracy.
2Manufacturing precision
If manual inversion mixing is performed, then dissolution accuracy is improved, but liquid leakage risk increases
Solution Approach 1:
The opening of the reagent container is preliminarily sealed with a seal member before the solvent dispensing and mixing process begins. This preliminary sealing action ensures that the container remains sealed during the automatic rotation and tilting movements, preventing liquid leakage while allowing the inversion mixing to proceed effectively for accurate dissolution.
3Extent of automation
If automation of inversion mixing is implemented, then labor saving is achieved, but device complexity increases
Solution Approach 1:
The reagent container is designed with multi-functionality, serving both as the storage vessel for the freeze-dried reagent and as the mixing mechanism itself. The container incorporates rotation and tilting capabilities, allowing it to perform both storage and automatic inversion mixing functions. This universal design achieves automation without requiring separate complex mixing devices, thereby limiting the increase in overall device complexity.
4Ease of operation
If the reagent container is opened for solvent dispensing, then solvent access is improved, but liquid spill-out risk increases during mixing
Solution Approach 1:
The opening of the reagent container is preliminarily sealed with a seal member before the solvent dispensing and mixing process begins. This preliminary sealing action ensures that the container remains sealed during the automatic rotation and tilting movements, preventing liquid spill-out while allowing effective inversion mixing to occur.
