Support Platform Air-Hole Layout for Uniform Non-Contact Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-contact transfer apparatuses consume excessive air due to large air intake hole diameters, leading to inefficient air pressure distribution and potential object damage during transfer.
Innovation Solution
The support platform features air intake holes with radially arranged sub-holes and inclined at a predetermined angle, reducing air consumption while maintaining desired pressure through increased flow rate, and alternating patterns of air intake and exhaust holes or slots for uniform pressure distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If air intake holes with large diameter are used, then air can be introduced easily, but air consumption increases excessively
Solution Approach 1:
The air intake hole is divided into multiple smaller sub-holes arranged radially. This segmentation allows air to be introduced effectively while reducing total air consumption compared to a single large hole, resolving the contradiction between ease of air introduction and air consumption.
Solution Approach 2:
The sub-holes are arranged radially around a central axis, creating localized air intake zones that distribute pressure uniformly. This local quality arrangement optimizes air flow patterns to reduce overall air consumption while maintaining effective air introduction.
2Productivity
If air intake holes with large diameter are used, then air flow rate increases, but pressure distribution becomes non-uniform
Solution Approach 1:
By segmenting the air intake into multiple radially arranged sub-holes, the system achieves both sufficient air flow rate and uniform pressure distribution. Each sub-hole contributes to localized pressure generation, and their radial arrangement ensures uniform overall pressure distribution across the platform surface.
Solution Approach 2:
The radial arrangement of sub-holes introduces a dimensional pattern that distributes air flow uniformly across the platform surface. This two-dimensional radial configuration transforms the pressure distribution from concentrated to uniform, resolving the contradiction between air flow rate and pressure uniformity.
3Reliability
If non-contact transfer is implemented, then object damage is reduced, but air consumption increases
Solution Approach 1:
The segmented radial hole structure enables non-contact transfer with reduced air consumption. The multiple small sub-holes create localized air cushions that lift the object gently without requiring large volumes of air, thus preventing object damage while minimizing air consumption.
Solution Approach 2:
By changing the geometric parameters of air intake holes from single large holes to multiple small radially arranged holes, the system achieves non-contact transfer with optimized air consumption. This parameter change maintains the benefits of non-contact transfer while reducing air usage.
