Expanding Radiative Flow Gap for Higher Adsorption Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing parallel radiative flow mechanisms are limited in their ability to generate sufficient absorption force due to the nature of the fluid flow and pressure distribution within the gap, which restricts their effectiveness in adsorption applications.
Innovation Solution
The expanding and radiative flow mechanism features a gap that increases in height radially from the fluid supply port, altering the fluid flow form to enhance the absorption force by increasing the radial velocity gradient and inertia effect, resulting in a lower pressure distribution and higher absorption force.

Engineering Contradiction Analysis
1Force
If a parallel gap is used in the radiative flow mechanism, then the structure is simple and easy to manufacture, but the absorption force is insufficient
Solution Approach 1:
The patent changes the geometric parameters of the gap from a parallel configuration to an expanding configuration where the gap height increases radially outward. This parameter change transforms the flow characteristics from decelerated parallel flow to expanding radiative flow, generating stronger negative pressure and significantly increasing the absorption force while maintaining structural simplicity
Solution Approach 2:
The patent introduces a vertical dimension to the gap structure by making the gap height variable in the radial direction. Instead of a two-dimensional parallel gap, the three-dimensional expanding gap creates additional flow path complexity that enhances the pressure gradient and absorption force without requiring multiple components
2Force
If the gap height continuously increases radially, then the absorption force is significantly increased, but the manufacturing precision requirements increase
Solution Approach 1:
The patent establishes specific parameter ranges for the expanding gap, including the radial length being 10 or more times the inlet gap height, and the gap height increasing linearly or nonlinearly. These parameter specifications balance the need for high absorption force with manufacturability by defining practical design boundaries
Solution Approach 2:
The patent allows different sections of the gap to have different height characteristics - the gap can increase linearly or nonlinearly within the radial length, and remain constant beyond it. This local differentiation optimizes the flow characteristics in different regions while simplifying manufacturing in areas where precise control is less critical
Applied Scientific Principles

This design significantly increases the absorption force compared to traditional parallel radiative flow mechanisms, as demonstrated by experimental tests showing a greater absorption force generated by the expanding and radiative flow mechanism.
Implementation Method 1
an inertia effect may form a positive pressure gradient
Implementation Method 2
the positive pressure gradient may form an inside-low outside-high pressure distribution in the parallel gap

AI summary
The present disclosure relates to an expanding and radiative flow mechanism. The mechanism has a bottom surface. The bottom surface is provided with a fluid supply port. The bottom surface of the mechanism and a surface of a to-be-adsorbed object form a gap during use. A fluid flows out from the fluid supply port, enters the gap and flows out along the gap. The gap is an expanding gap and meets the following: a radial length exists with the fluid supply port as an initial point of the flow, and a height of the gap continuously increases in an outward radial direction within this length. With improvements to a parallel radiative flow mechanism, the mechanism of the present disclosure can effectively increase an absorption force of a radiative flow, which is conducive to subsequent applications thereof.
