Concave Impact Body for Wide Pneumatic Material Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pneumatic distribution machines require a large number of distribution elements and conveying lines to achieve a wide distribution width, leading to complexity and increased weight, especially in machines with large working widths.
Innovation Solution
The impact body features concave reflective surface sections on opposite sides diverging in opposite directions, connected by a semi-ring section, which allows for a wider distribution width and ensures uniform lateral distribution by compensating for decreasing distribution quantities with partial overlap of scattering patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional flat impact plates are used, then the structure is simple, but the distribution width is limited and requires many distribution elements
Solution Approach 1:
The patent applies curvature by replacing conventional flat impact plates with impact bodies featuring concave reflective surfaces. The concave geometry causes scattered material to reflect and redistribute across a wider area, achieving broader distribution width with fewer distribution elements. The curved surface transforms the scattering pattern to cover a larger stationary area without increasing device complexity.
2Area of stationary object
If more distribution elements are added to increase distribution width, then coverage area increases, but machine weight and complexity increase
Solution Approach 1:
The concave reflective surfaces on impact bodies concentrate and redirect scattered material more efficiently, allowing a reduced number of distribution elements to achieve the same or greater distribution width. This reduction in the number of elements directly decreases machine weight while maintaining or improving coverage area.
3Area of stationary object
If conventional impact plates are used, then manufacturing is simple, but distribution uniformity across wide areas is poor
Solution Approach 1:
The concave reflective surfaces are designed with specific geometric parameters to control the reflection and scattering of material. This curvature geometry creates a more uniform distribution pattern across wide areas by redistributing material that would otherwise concentrate in certain zones, improving manufacturing precision in terms of distribution uniformity.
Solution Approach 2:
The impact bodies feature locally optimized concave surfaces with specific radii of curvature tailored to achieve uniform distribution. Different regions of the concave surface are designed to redirect material to specific zones, ensuring homogeneous distribution across the entire distribution width while maintaining manufacturability.
