Solution Overview
Problem
Existing devices fail to create a laminar swirling flow of fluid effectively, as they either do not utilize the Coanda Effect to enhance flow velocity or do not produce a laminar flow along the same plane, limiting the efficiency of fluid flow control.
Innovation Solution
A transmission base with a side penetrable hole featuring a convex curve edge that deflects incoming fluid to attach to a convex curve, inducing the Coanda Effect and creating a laminar swirling flow within the internal cavity, while allowing for stacking to increase efficiency.

Engineering Contradiction Analysis
1Speed
If fluid flows through a side penetrable hole with a convex curve edge, then a laminar swirling flow is created with enhanced velocity, but the device complexity increases due to the specific geometric requirements
Solution Approach 1:
The side penetrable hole is designed with a convex curve edge instead of a straight edge, creating a curved surface that引导 the fluid flow to attach and follow the curve. This curvature enables the Coanda Effect to occur, causing the fluid to adhere to the convex surface and generate a laminar swirling flow pattern with enhanced velocity within the internal cavity.
Solution Approach 2:
The angle of the convex curve edge is specifically optimized to be the smallest angle of deviation to the emerging axis of the hole. This parameter optimization ensures that the fluid flow attaches smoothly to the convex curve and maximizes the Coanda Effect, thereby achieving the desired laminar swirling flow with high velocity while controlling the geometric complexity.
2Productivity
If multiple transmission bases are stacked, then the working efficiency and height are increased, but the manufacturing complexity increases
Solution Approach 1:
The device is divided into multiple identical transmission base modules that can be stacked vertically. Each module contains the complete functional elements (internal cavity, side penetrable hole with convex curve edge), allowing independent manufacturing and assembly. This segmentation enables increased working efficiency and height by stacking multiple units while maintaining standardized manufacturing processes for each module.
Solution Approach 2:
Each transmission base is designed as a universal module that can function independently or be combined with other identical modules. The standardized design of the side penetrable hole and internal cavity ensures that each unit performs the same fluid flow control function, allowing flexible stacking configurations to achieve different heights and efficiency levels without requiring custom manufacturing for each assembly.

AI summary
An apparatus for creating a swirling flow of fluid comprises a transmission base (1) with an internal cavity (2) to receive the fluid flow from outside via a side hole (3) which will become a hole side edge (4) to control the flow through of the fluid into the transmission base in a laminar swirling flow in the internal cavity of the transmission base. A part of the hole side edge may have an elevated insert supporting shoulder (10) to support the overlay attachment of another transmission base to stack them higher.
