Deep-Drawn Reservoir Eliminates Weld Seams in Agricultural Spreaders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural spreader designs are time-consuming to produce and prone to rust, especially when using welded connections for storage containers with multiple discharge funnels, which complicates assembly and maintenance.
Innovation Solution
A modular system where the reservoir with discharge funnels is formed as a single, seamless component through deep-drawing processes from sheet steel or plastic, allowing for easy assembly and replacement of components, and incorporating rust-resistant materials to minimize rust formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reservoir with discharge funnels is formed by welding individual walls together, then the structural integrity is maintained, but the production time increases and rust formation occurs at weld seams
Solution Approach 1:
The patent merges multiple individual walls into a single integrated reservoir structure formed by deep-drawing processes. This eliminates the need for welding connections between separate walls, thereby reducing production time while maintaining structural integrity through the continuous formed structure.
Solution Approach 2:
The patent replaces the mechanical welding process with a deep-drawing forming process. Instead of joining separate components through welding, the reservoir is formed as a single piece from sheet material through controlled plastic deformation, eliminating weld seams and associated rust problems.
2Ease of manufacture
If the reservoir with discharge funnels is formed by screw connections, then the assembly is possible, but the production time increases
Solution Approach 1:
The patent combines multiple separate components (reservoir walls, discharge funnels) into a single integrated structure formed by deep-drawing processes. This eliminates the need for screw connections and assembly operations, significantly reducing production time while maintaining ease of manufacture through a standardized forming process.
3Adaptability or versatility
If the reservoir is designed with separate discharge funnels, then the dosing devices can be independently arranged, but the number of connection points increases leading to more rust formation
Solution Approach 1:
The patent merges the reservoir body and discharge funnels into a single continuous structure formed by deep-drawing processes. This eliminates connection points between separate components, thereby preventing rust formation at joints while maintaining the ability to independently arrange dosing devices at the discharge areas.
4Ease of manufacture
If the reservoir walls are made as independent components, then the manufacturing flexibility is improved, but the assembly complexity and time increase
Solution Approach 1:
The patent combines multiple independent walls into a single integrated reservoir structure formed by deep-drawing processes. This reduces assembly complexity by eliminating the need to join multiple components, while maintaining manufacturing flexibility through the standardized deep-drawing process that can accommodate various designs.

AI summary
The building block system has a container (2) arranged at a frame element (1), where an article element (18) is subsequently formed at an upper circulating region of the container. Hoppers are arranged at respective bottom portions, where a funnel-shaped dosing device is provided at a discharge region. The hoppers are formed by single-piece sheet steel plates through deep drawing process.
