Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialized devices are used for specific operations (filtration, sedimentation, cytocentrifugation), then the operation quality is improved, but the device versatility deteriorates
Solution Approach 1:
The device combines multiple functional components (holder for centrifugal tubes, insert with recesses for various carriers, lid with vacuum connection) into a single system that can perform filtration, sedimentation, cytocentrifugation, and washing operations. The holder accommodates different vessel types, the insert supports multiple carrier formats, and the integrated tools enable various sample handling techniques without requiring separate specialized devices.
2Reliability
If multiple specialized devices are used for different operations, then the operation quality is improved, but the device complexity increases
Solution Approach 1:
The patent merges previously separate devices and tools into a single integrated system. The holder, insert, lid, and various tools (filters, seals, supports) are combined into one device that can perform multiple operations. This reduces the number of separate devices needed while maintaining the quality of each operation through properly integrated components.
3Adaptability or versatility
If a multifunctional device is created, then the device versatility is improved, but the ease of operation deteriorates
Solution Approach 1:
The device is divided into separable components (holder, insert, lid, tools) that can be easily assembled and disassembled. The insert with its recesses for different carriers can be configured for specific operations, and tools can be attached or removed as needed. This modular design maintains versatility while simplifying operation through clear component separation and standardized interfaces.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a multifunctional platform for handling solvents and mixtures, enabling efficient filtration, sedimentation, and washing of samples, replacing the need for specialized cytocentrifugation methods and allowing for subsequent treatments like staining and protein detection, with improved user convenience and protection against evaporation.
Implementation Method 1
Its primary use is aimed at the situations when centrifugal forces and forces generated by a vacuum pump are used for the treatment of samples
Implementation Method 2
forces generated by a vacuum pump are used for the treatment of samples
Implementation Method 3
The thread serves for connecting the two parts and to create a pressure on the insert, placed inside the holder, and on the at least one tool, also placed inside the holder
