Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hollow cones are used for mixing and agitation, then the device can accelerate liquid on both inner and outer sides, but the device cannot handle particulate-containing liquid products due to particle-size limitation
Solution Approach 1:
The invention extracts the flow path from the hollow cone structure and relocates it to the external region. The cones are changed from hollow to full-body structures, removing the internal flow passage constraint. Liquid now flows only on the external surface of the cones, eliminating particle-size limitations while maintaining the mixing and agitation function.
Solution Approach 2:
The invention inverts the traditional hollow cone design by using full-body cones. Instead of having liquid flow through the interior of hollow cones, the liquid flows on the external surface of solid cones. This inversion transforms the device from one with internal flow constraints to one with external flow freedom, enabling handling of particulate-containing liquids.
2Productivity
If hollow cones with internal flow are used, then mixing and agitation can be achieved, but pumping capacity is limited
Solution Approach 1:
The invention extracts the flow path from the hollow cone interior and places it externally. This allows the full external surface of the cones to be utilized for liquid acceleration and pumping, significantly increasing pumping capacity compared to the limited internal flow path of hollow cones.
Solution Approach 2:
The invention transitions from internal one-dimensional flow through hollow cones to external two-dimensional surface flow. Liquid flows on the external conical surfaces, utilizing a larger dimensional space for flow, which enhances pumping capacity and liquid handling efficiency.
3Adaptability or versatility
If hollow cone structure is used, then liquid can be accelerated on both inner and outer sides, but the device is primarily suitable for comminution or micronization
Solution Approach 1:
By removing the hollow interior and retaining only the external conical surface, the device is transformed from a dual-flow (internal and external) system to a single external flow system. This simplification enables the device to handle particulate-containing liquids while maintaining its mixing and agitation capabilities, expanding its application range.
Solution Approach 2:
The invention inverts the conventional hollow cone design by using solid full-body cones. This inversion changes the flow regime from internal-through-flow to external-surface-flow, making the device suitable for applications involving particulate-containing liquids, commixing, and agitation rather than just comminution or micronization.
