Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquids are mixed in a separate container before supply, then mixing efficiency is improved, but the time required to start the separation process increases
Solution Approach 1:
The patent combines the mixing function and supply function into a single syringe unit. Liquid A and liquid C are mixed directly within the syringe barrel, eliminating the need for a separate mixing container and transfer process. This integration allows the mixed liquid to be immediately supplied to the separation device, thereby improving productivity while minimizing time loss.
Solution Approach 2:
The syringe is pre-filled with liquid C before liquid A is added. This preliminary preparation ensures that when liquid A is introduced, mixing can begin immediately without waiting for separate container preparation. The pre-positioned liquid C ready for mixing reduces the overall time to start the separation process.
2Loss of time
If a syringe is used to mix and supply liquid, then the time to start separation is reduced, but the complexity of the liquid supply unit increases
Solution Approach 1:
The syringe is designed to perform multiple functions: it serves as a mixing chamber where liquid A and liquid C combine, as a containment vessel for the mixed liquid, and as a supply mechanism that delivers the mixed liquid to the separation device. This multi-functionality reduces the need for additional components, thereby limiting the increase in device complexity while achieving rapid start time.
Solution Approach 2:
The syringe structure inherently provides mixing capability through its design - when liquid A is injected into the syringe containing liquid C, the fluids mix within the syringe barrel without requiring external mixing devices. The syringe serves itself as both mixer and dispenser, minimizing added complexity.

AI summary
A particle separation apparatus includes: a liquid supply unit A that supplies a liquid A to a separation device; and a control unit that controls the liquid supply unit A. A syringe is attached to the liquid supply unit A, and the liquid supply unit A produces a mixed liquid by mixing the liquid A and a liquid C in the syringe and supplies the liquid A from the syringe to the separation device as the mixed liquid. The control unit performs control to produce the mixed liquid in the syringe by suctioning the liquid A and the liquid C into the syringe.
