Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an RFID device is integrated into the centrifuge container to enable wireless communication and cycle tracking, then monitoring precision and operational reliability are improved, but device complexity increases
Solution Approach 1:
The patent replaces mechanical counting methods with an RFID-based wireless communication system. The RFID device in the container communicates cycle information wirelessly to the centrifuge control unit, eliminating the need for complex mechanical sensors or physical counters integrated into the container structure.
Solution Approach 2:
The RFID device acts as an intermediary between the centrifuge container and the control system. It stores cycle information and communicates it wirelessly to the centrifuge, allowing the container to be read without physical contact or complex integration with the centrifuge structure.
2Adaptability or versatility
If the centrifuge container is used across multiple different centrifuges to increase versatility, then adaptability is improved, but the ability to accurately track cycle history across machines deteriorates
Solution Approach 1:
The RFID device provides universal identification and tracking across different centrifuge machines. Each container has a unique RFID tag that can be read by any centrifuge's reading device, creating a universal system that tracks cycle history regardless of which specific centrifuge the container is used in.
Solution Approach 2:
The system implements feedback by having the centrifuge control unit read the RFID device's cycle count information and update it. This feedback loop ensures that cycle history is continuously maintained and synchronized across all centrifuges, preventing information loss when containers are interchanged between machines.
3Reliability
If the RFID device is positioned to withstand high rotational speeds and accelerations, then reliability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent segments the RFID device into a separate, self-contained unit that can be independently manufactured and then attached to the container. This segmentation allows the RFID device to be optimized for durability through separate engineering, while the attachment mechanism can be simplified for easy manufacturing.

AI summary
The invention relates to a centrifuge container (4) used in a laboratory centrifuge (1). According to the invention, the centrifuge container (4) has an RFID device (11). The RFID device (11) can communicate with the laboratory centrifuge (1). This communication can include, for example, the number of operating cycles the centrifuge container (4) has undergone, the centrifugation duration, the angular velocity of the rotation of the centrifuge container (4), the acceleration of the centrifuge container (4), the oscillation angle of the centrifuge container (4), and/or the temperature inside the centrifuge container (4). It is also possible that the centrifuge container (4) has a storage unit in which the centrifugation cycles undergone by the centrifuge container (4) are stored.In this way, the cycle status of the centrifuge container (4) can be recorded regardless of which laboratory centrifuge (1) is used to operate the centrifuge container (4).
