Solution Overview
Problem
Conventional reaction vessel automatic loading devices face difficulties in dropping contaminated reaction vessels from the pickup mechanism, leading to instrument failures due to improper handling and storage during delivery.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If reaction vessels are allowed to drop under their own weight from the pickup mechanism, then the device complexity is reduced, but the reliability deteriorates due to contamination causing difficult release and instrument failure
Solution Approach 1:
The pickup mechanism incorporates a shaking function that vibrates the pickup block to facilitate the release of reaction vessels. When contamination causes the reaction vessel to stick to the bearing surface, the mechanical vibration disrupts the adhesion and enables the vessel to drop properly into the transport mechanism, thereby maintaining reliability without significantly increasing device complexity.
Solution Approach 2:
The pickup mechanism transitions from a static holding position to a dynamic shaking state during the release phase. The control unit activates the shaking function only when needed for release, allowing the system to adapt its behavior based on the operational phase. This dynamic approach ensures reliable release even when contamination occurs, while maintaining simplicity during the transport phase.
2Ease of operation
If the pickup mechanism uses a simple gravity-based drop method, then the ease of operation is improved, but the reliability worsens due to contamination causing improper handling and instrument failure
Solution Approach 1:
The shaking function provides an additional operational mode that activates when contamination is detected or suspected. The mechanical vibration assists the gravity-based drop method by disrupting contamination bonds, ensuring reliable release without requiring manual intervention. This maintains ease of operation while correcting the reliability issue caused by simple gravity-based dropping.
Solution Approach 2:
The pickup mechanism automatically activates the shaking function when the reaction vessel fails to drop properly under gravity. The system self-corrects the contamination issue without requiring external intervention, maintaining ease of operation while ensuring reliable delivery. The control unit monitors the dropping process and triggers the shaking function only when necessary.
3Reliability
If reaction vessels are contaminated during delivery or storage, then the reliability deteriorates, but adding complex cleaning mechanisms would increase device complexity
Solution Approach 1:
The shaking function serves as a preventive measure that disrupts contamination bonds before they cause instrument failure. By applying mechanical vibration during the release phase, the system prevents contaminated vessels from being improperly handled or stored, thereby maintaining reliability without requiring complex cleaning mechanisms. The vibration is applied only during the critical release moment, minimizing added complexity.
4Reliability
If the pickup mechanism pauses and shakes to facilitate vessel drop, then the reliability improves, but the productivity decreases due to additional time required for each loading cycle
Solution Approach 1:
The shaking function is activated periodically only when the reaction vessel fails to drop under gravity, rather than continuously for every vessel. The control unit monitors the dropping process and triggers the shaking function only when contamination is detected. This periodic intervention maintains reliability while minimizing the impact on productivity, as most vessels can still drop quickly under gravity without requiring the shaking phase.

the control unit sending a control signal that enables the driving structure to drive each of the pickup blocks to pause and/or shake after moving for a first preset period of time or by a preset distance
Data Source
AI summary
A reaction vessel pickup mechanism, an automatic loading device, a sample analyzer, and a loading method are disclosed. Driven by a driving structure, each of the pickup blocks moves in a first preset time or a preset distance and then stops or shakes, so that a reaction vessel is dropped from the pickup blocks more easily.
