Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a porous glass membrane filter is used, then filtration is achieved, but sliding resistance becomes high and emulsion formation is insufficient
Solution Approach 1:
The patent uses a porous polytetrafluoroethylene (PTFE) membrane instead of porous glass membrane. The PTFE membrane provides effective filtration while maintaining low sliding resistance, resolving the contradiction between filtration capability and ease of operation. The porous structure allows fluid passage while the PTFE material properties reduce friction during pumping operations.
Solution Approach 2:
The patent changes the material parameter from glass to PTFE, which fundamentally alters the friction characteristics. This material substitution transforms the surface properties to achieve both effective filtration and low sliding resistance, solving the technical contradiction between reliable filtration and ease of pumping operation.
2Productivity
If extensive pumping operation is performed, then mixing is improved, but time consumption increases and emulsion formation remains insufficient for some compositions
Solution Approach 1:
The patent introduces a T-shaped mixing piece as an intermediary mixing element. This mixing piece with its specific geometry (T-shape with protrusions) actively facilitates phase mixing during the pumping process, reducing the number of pumping cycles needed to achieve adequate emulsion formation. The mixing piece acts as a mediator that enhances mixing efficiency without requiring extended pumping time.
Solution Approach 2:
The reciprocating pumping operation creates mechanical vibration and turbulence in the fluid stream as it passes through the filter membrane and around the T-shaped mixing piece. This mechanical agitation enhances the mixing of continuous and dispersed phases, improving emulsion formation efficiency and reducing the time required for adequate mixing.
3Device complexity
If a simple connector structure is used, then device complexity is reduced, but emulsion formation capability is insufficient for diverse chemical compositions
Solution Approach 1:
The patent designs a multi-functional connector that integrates filtration (porous PTFE membrane), active mixing (T-shaped mixing piece with protrusions), and emulsion formation capabilities into a single device. This universal design allows the connector to effectively handle diverse chemical compositions while maintaining relatively simple overall structure, resolving the contradiction between device complexity and adaptability.
Solution Approach 2:
The patent employs composite structural elements, particularly the T-shaped mixing piece that combines geometric features (protrusions, specific shape) with the filtering membrane. This composite approach creates a device that achieves enhanced emulsion formation capability for diverse chemical compositions while maintaining structural simplicity through the integration of multiple functions into unified components.
