Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional centrifugal separation container is used, then the structure is simple and operation is easy, but tissue and fluids flow backward during centrifugation causing separation failure
Solution Approach 1:
The patent applies the dynamics principle by making the container structure adaptable to centrifugal forces. The container includes a movable piston that responds dynamically to the centrifugal force during rotation, allowing the internal structure to adjust and prevent backflow automatically. This dynamic adaptation resolves the contradiction by maintaining reliability through force-responsive design rather than complex static structures.
Solution Approach 2:
The patent changes physical parameters by utilizing the centrifugal force itself as a control parameter. The container design incorporates elements that respond to the magnitude and direction of centrifugal force, such as the movable piston that shifts position based on rotation speed. This parameter-based control prevents backflow without requiring complex mechanical valves or seals.
2Productivity
If a traditional centrifugal separation container is used, then the configuration is simple, but it requires long paths for injecting and discharging materials making extraction difficult
Solution Approach 1:
The patent applies dimensionality change by reconfiguring the material flow path from a long linear path to a more compact three-dimensional arrangement. The container design incorporates vertical and radial dimensions that allow materials to be injected and discharged over shorter distances while maintaining effective separation. This reduces the overall path length and improves extraction efficiency.
Solution Approach 2:
The patent uses nesting by placing the discharge path within or alongside the injection path in a compact arrangement. The container structure allows discharge conduits to be nested within the main body or positioned to share space with injection mechanisms, thereby reducing the overall material path length without compromising functionality.
3Ease of operation
If a traditional centrifugal separation container is used, then the structure is simple, but connecting discharging means to the containers is difficult
Solution Approach 1:
The patent applies universality by designing the container with standardized, multi-functional connection interfaces. The discharge means are integrated with universal connection features that can accommodate different attachment types and configurations, making connection straightforward without requiring complex specialized mechanisms for each specific application.
Solution Approach 2:
The patent implements self-service through automatic connection features where the discharge means can be easily attached or detached without complex tools or procedures. The container design includes self-aligning or self-sealing connection elements that simplify the attachment process, allowing operators to connect discharge means quickly and reliably without requiring complex manual intervention.
