Solution Overview
Problem
Existing animal bedding and fodder dispensing machines face issues with rigidity, deformation, and jamming due to dense and wet products, leading to inefficient chopping and potential collisions, as well as accumulation and imbalance problems.
Innovation Solution
The machine features blades formed by a box structure with lateral closing plates connected to the disc, providing increased rigidity and allowing for wider, heavier knives, ensuring smooth product flow and reduced accumulation, while maintaining dynamic balance during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If thin flat sheets are used as turbine blades, then the device complexity is reduced, but the rigidity and strength of the blades deteriorate, causing deformation under dense products
Solution Approach 1:
The blade is segmented into multiple components: a central plate, multiple radial branches, and lateral closing plates. This segmentation allows each component to be optimized independently while collectively providing the necessary rigidity and strength to handle dense products without deformation
Solution Approach 2:
The blade employs a composite structure combining flat plates with box-shaped sections formed by lateral closing plates. This composite design integrates the simplicity of flat sheets with the rigidity of enclosed sections, creating a blade that is both structurally sound and manufacturable
2Ease of manufacture
If simple flat blades are used, then the manufacturing cost is reduced, but the chopping efficiency of dense and wet products deteriorates
Solution Approach 1:
The blade is divided into a central plate, radial branches, and lateral closing plates that form box sections. This segmentation enables efficient chopping of dense products while maintaining manufacturing simplicity through standardized plate components that can be assembled systematically
Solution Approach 2:
The blade transitions from a two-dimensional flat sheet to a three-dimensional box structure by adding lateral closing plates. This dimensional enhancement increases the blade's capacity to handle and chop dense, wet, long-stranded products efficiently while retaining ease of manufacture through plate assembly
3Device complexity
If hollow cylinder and flat plates with sharp edges are used, then the device complexity is reduced, but product flow smoothness deteriorates, causing accumulation and imbalance
Solution Approach 1:
Instead of using a hollow cylinder with sharp edges that creates geometric asperities, the invention uses a solid plate structure with smooth surfaces. This inversion of the design approach eliminates product accumulation points and ensures smooth flow from the center to the periphery, preventing imbalance
Solution Approach 2:
The plate structure with smooth surfaces creates a homogeneous flow environment for products, eliminating the geometric asperities and sharp edges that cause accumulation. This homogeneous design ensures uniform product distribution and maintains turbine dynamic balance during operation
