Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distribution assemblies for seeders face issues with inefficient and messy emptying of residual granular material, particularly seeds, which often result in waste and inconvenience due to the need for immediate container placement during the emptying process.
Innovation Solution
A positionable discharge chute that can be configured in intermediate and flow positions, allowing granular elements to be stored in a buffer zone before emptying, enabling preparation for optimal emptying without direct spillage, and facilitating ergonomic handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a drain chute is used to empty residual seeds, then emptying efficiency is improved, but seeds may spill to the ground causing waste and mess
Solution Approach 1:
The discharge chute is designed with an intermediate position that allows the operator to prepare for emptying before actually discharging seeds. The chute can be positioned to direct seeds into a container placed on the ground, preventing spillage. This preliminary positioning action ensures that when emptying occurs, seeds are directed accurately and do not waste.
Solution Approach 2:
The discharge chute acts as an intermediary device between the seed storage chamber and the ground/container. By introducing this intermediate element, seeds are not discharged directly to the ground but are instead guided through the chute into a properly positioned container, eliminating the harmful effect of seed waste while maintaining efficient emptying.
2Device complexity
If the discharge chute is fixed in position, then structural simplicity is maintained, but the operator cannot prepare for optimal emptying positioning
Solution Approach 1:
The discharge chute is designed with movable mounting elements that allow it to be positioned in different locations (intermediate positions) along the side of the housing. This dynamic positioning capability enables the operator to prepare for optimal emptying by placing the chute in the most convenient position before opening the door, while the overall structure remains relatively simple and does not require complex mechanisms.
