Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple blades are provided to generate turbulent flow, then bubble generation efficiency is improved, but device complexity increases
Solution Approach 1:
The device segments the flow activation function into multiple independent blades arranged around the shaft. Each blade independently generates turbulent flow in the fluid, collectively achieving enhanced bubble generation efficiency without requiring a single complex mechanism
Solution Approach 2:
The invention adds the radial dimension by arranging multiple blades circumferentially around the shaft, transforming a single-axis rotation system into a multi-dimensional flow generation system. This allows simultaneous activation of fluid at multiple radial positions, improving bubble generation efficiency while maintaining simple shaft rotation
2Stability of the object's composition
If ribs are added to the inner peripheral surface of the tubular body, then mixing uniformity is improved, but manufacturing complexity increases
Solution Approach 1:
The invention applies ribs only to the inner peripheral surface of the tubular body where fluid flow occurs, rather than throughout the entire structure. This localized modification enhances mixing uniformity at the critical flow interface while minimizing additional manufacturing complexity
Solution Approach 2:
The ribs are designed with curved surfaces that follow the rotational flow pattern of the fluid. This curvature design promotes uniform mixing by guiding fluid along smooth paths while reducing stress concentration, and can be manufactured using standard rotational molding or machining techniques

Implementation Method 1
multiple blades that are provided between the outer peripheral surface of the shaft and an inner peripheral surface of the tubular body while forming a flow path extending spirally from one end of the tubular body toward another end of the tubular body, and that generate a turbulent flow in fluid flowing in the flow path
Implementation Method 2
a tubular peripheral wall has an inner peripheral surface provided with multiple ribs each composed of a ridge extending in an axial direction of the shaft
