Internal-Frame Grain Cart Hopper for Stronger, Simpler Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grain carts are large and complex to assemble, and their structural strength is critical for handling heavy loads of particulate material, necessitating a simpler and more robust construction method.
Innovation Solution
A grain cart structure featuring a support frame with a spine member and rib members connected by cross braces, paired with panels that align with flange apertures to form side walls, enhancing structural integrity while allowing easy assembly.

Engineering Contradiction Analysis
1Strength
If traditional grain cart construction methods are used, then structural strength is sufficient to handle heavy loads, but assembly complexity increases significantly
Solution Approach 1:
The grain cart structure is divided into modular components including panels, rib members with flanges, and cross braces that can be independently manufactured and assembled. The side walls are constructed from multiple panels that attach to rib members, allowing the structure to be built in segments rather than as a single complex unit.
Solution Approach 2:
The rib members combine multiple functions into single components - they provide structural support, include flanges with apertures for panel attachment, and serve as attachment points for cross braces. This merging of functions reduces the total number of separate parts needed and simplifies the assembly process while maintaining structural integrity.
2Reliability
If traditional grain cart construction methods are used, then structural integrity is maintained, but manufacturing time and effort increase
Solution Approach 1:
The rib members are pre-configured with flanges and apertures during manufacturing, and panels are designed with matching attachment features. This preliminary preparation of connection interfaces allows for rapid assembly without requiring complex field modifications or custom fitting procedures.
Solution Approach 2:
The structure is segmented into standardized panels and rib members that can be manufactured separately and assembled quickly. This segmentation allows parallel manufacturing of components and simplifies the on-site assembly process, significantly reducing total construction time while maintaining structural integrity through standardized connection methods.

AI summary
A grain cart is provided with an internal frame and a method of constructing a grain cart with an internal frame is provided. The grain cart can have a support frame, ground wheels, a hitch assembly, and a storage hopper supported on the support frame. The storage hopper can have a spine member running along the center portion, corresponding pairs of rib members connected at intervals along the spine member and a plurality of panels connected between adjacent rib members. The storage hopper can be constructed by connecting a plurality of rib members to a spine member, connecting a cross brace across corresponding pairs of rib members, inserting panels between adjacent rib members, and connecting the panels to rib members.
