Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bioprocessing systems for liquid immune or naive cell cultures face challenges in ensuring safety and compliance due to centralized control systems that may not fully understand the bioprocess they are performing, potential system errors, and the need for manual adjustments, which can lead to errors and complications in documentation and product safety.
Innovation Solution
A decentralized approach where a virtual identity is assigned to each cell culture, stored in a local control unit that travels with the culture, allowing for independent data gathering and validation of ambient conditions, reducing the risk of system errors and ensuring accurate documentation through redundant safety checks and encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a centralized control system is used to manage the bioprocess, then automation and coordination of multiple processing steps are improved, but system complexity and potential points of failure increase
Solution Approach 1:
The patent divides the centralized control system into distributed control units, each attached to specific processing steps or containers. Each control unit independently manages its local operations while communicating with others, segmenting the overall system into manageable, autonomous parts that reduce central complexity while maintaining automation.
Solution Approach 2:
The patent introduces control units as intermediary components between the centralized system and individual processing steps. These intermediaries translate centralized commands into local actions and relay status information back, reducing direct system complexity while preserving automated coordination capabilities.
2Adaptability or versatility
If manual adjustments and configurations are performed for each cell culture, then adaptability to individual patient needs is improved, but error risk and time consumption increase
Solution Approach 1:
The patent implements self-service functionality where control units automatically configure and execute processing steps based on pre-loaded protocols specific to each patient's cell culture requirements. The system autonomously adjusts parameters and sequences without manual intervention, maintaining adaptability while eliminating human error.
Solution Approach 2:
The patent performs preliminary configuration of processing protocols and parameters before the actual bioprocess begins. Control units are pre-programmed with patient-specific instructions, allowing the system to automatically execute customized workflows without manual adjustments during execution, thereby reducing error risk while maintaining adaptability.
3Productivity
If multiple reagents and equipment are used in the bioprocess, then processing capability and versatility are improved, but documentation complexity and compliance burden increase
Solution Approach 1:
The patent implements feedback mechanisms where control units automatically track, monitor, and record all reagent usage, processing steps, and equipment operations. This automated feedback loop continuously updates documentation with actual process data, reducing manual documentation complexity while maintaining comprehensive records of all processing activities for compliance.
Solution Approach 2:
The patent replaces manual documentation processes with automated electronic recording systems. Control units electronically log all reagent additions, processing parameters, and equipment operations, substituting mechanical/manual documentation with digital tracking that reduces complexity while maintaining complete process records.
4Reliability
If redundant safety checks are implemented, then cell culture safety is improved, but system complexity and resource consumption increase
Solution Approach 1:
The patent implements self-service safety monitoring where control units autonomously perform redundant checks of critical parameters such as temperature, pressure, and contamination levels. The system self-verifies conditions and automatically alerts operators to deviations, providing redundant safety without requiring complex external monitoring systems.
Solution Approach 2:
The patent makes safety checks dynamic by adjusting the frequency and type of redundant monitoring based on real-time process conditions. The system increases monitoring intensity when anomalies are detected and reduces routine checks during stable operation, providing adaptive redundancy that maintains safety while minimizing unnecessary system complexity.

AI summary
The invention relates to a method for performing and supporting a bioprocess performed on a liquid immune or naive cell culture, wherein the bioprocess is performed on the cell culture to obtain a processed cell culture, wherein the processed cell culture is destined for autologous or allogenic cell therapy, wherein the bioprocess is performed by an integrated bioprocessing system (1) performing multiple unit operations on the cell culture, wherein a virtual identity (5) is assigned to the cell culture, wherein the virtual identity (5) is stored by a control unit (7) in a local memory (8), wherein the control unit (7) gathers data about the surroundings of the cell culture while the cell culture is processed by the integrated bioprocessing system (1) and wherein the gathered data is stored assigned to the virtual identity (5). It is proposed, that the cell culture is transported from a first location to a second location and that the control unit (7) including the memory is transported with the cell culture from the first location to the second location.
