Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transverse conveyors in agricultural harvesting machines face inefficiencies in crop conveyance, particularly at the edge sections where crops can get stuck or conveyed slowly, leading to reduced overall performance.
Innovation Solution
The design features a transverse conveyor with a smaller distance between adjacent windings at the lateral edge sections compared to the central section, incorporating additional spiral-like elements between the helical turns to enhance conveying efficiency, allowing for faster crop transfer and reduced risk of crops falling out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the distance between adjacent windings is uniform throughout the transverse conveyor, then the structure is simple and easy to manufacture, but the conveying effect is reduced at the lateral edge sections where crops can get stuck
Solution Approach 1:
The patent applies local quality by varying the distance between adjacent windings of the transverse conveyor elements based on the radial position. At the lateral edge sections, the distance is smaller to prevent crops from getting stuck and improve conveying effect, while at the central section the distance is larger. This non-uniform spacing optimizes the conveying performance at different locations of the conveyor.
2Productivity
If the distance between adjacent windings is smaller at lateral edge sections, then the conveying effect is improved and crops are conveyed faster, but the manufacturing complexity increases
Solution Approach 1:
The patent applies parameter changes by modifying the spacing parameter between adjacent windings as a function of radial position. The distance between windings is deliberately made smaller at lateral edge sections and larger at the central section, creating an optimized conveying configuration that balances performance and manufacturability.
3Productivity
If additional spiral-like elements are added between helical turns, then the conveying capacity is enhanced, but the device complexity increases
Solution Approach 1:
The patent applies another dimension by introducing spiral-like elements that extend in the axial direction between the helical turns. These additional elements provide extra conveying paths and increase the conveying capacity by utilizing the axial dimension, effectively adding more conveying functionality without significantly complicating the overall structure.
