Boxed Plate Frame for High-Clearance Sprayers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-clearance agricultural sprayers require stronger and heavier frames to support increased loads and accessories, leading to complex and time-consuming fabrication processes with ladder-style tube frames.
Innovation Solution
A boxed plate construction frame with varying thicknesses at different portions of the chassis frame, providing additional strength where needed while maintaining a lighter weight, using thicker materials only where required, such as under the boom and engine supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If ladder-style tube frames with numerous large sections are used to support increased loads and accessories, then the frame strength is improved, but the frame weight and fabrication complexity increase
Solution Approach 1:
The patent applies local quality by varying the plate thickness at different locations of the frame. Thicker plates are used at high-stress areas (such as where booms and accessories are mounted) while thinner plates are used in lower-stress areas, thereby providing necessary strength only where required and reducing overall frame weight.
Solution Approach 2:
The patent changes the physical parameter of plate thickness to optimize the frame structure. By adjusting the thickness parameter of plates at different locations, the frame achieves optimal strength-to-weight ratio, providing sufficient strength at critical locations while minimizing overall weight.
2Strength
If ladder-style tube frames with numerous large sections are used to provide mounting locations for components and accessories, then the frame strength and mounting capability are improved, but the fabrication time and complexity increase
Solution Approach 1:
The patent segments the frame into modular boxed plate sections that can be fabricated separately and then assembled. This segmentation allows for standardized production of frame components, reducing overall fabrication time and complexity while maintaining structural integrity.
Solution Approach 2:
The patent merges multiple structural functions into a single boxed plate frame structure. The frame simultaneously provides structural support, mounting locations for accessories, and structural rigidity, eliminating the need for separate reinforcement components and reducing fabrication steps.
3Strength
If thicker materials are used throughout the entire frame to provide additional strength, then the frame strength is improved, but the overall frame weight increases
Solution Approach 1:
The patent applies local quality by varying the plate thickness at different locations of the frame. Thicker plates are used at high-stress areas (such as where booms and accessories are mounted) while thinner plates are used in lower-stress areas, thereby providing necessary strength only where required and reducing overall frame weight.
Solution Approach 2:
The patent changes the physical parameter of plate thickness to optimize the frame structure. By adjusting the thickness parameter of plates at different locations, the frame achieves optimal strength-to-weight ratio, providing sufficient strength at critical locations while minimizing overall weight.

Function Achieved in This Case
The boxed plate frame offers improved strength and reduced weight compared to traditional ladder-style frames, enhancing the structural integrity and efficiency of high-clearance sprayers without the complexity and weight of current designs.
Implementation Method 1
The plurality of plates of the top plate of the first section may be greater than the plurality of plates of the top plate of the second section

AI summary
A chassis frame for an agricultural sprayer includes a top plate, a bottom plate spaced apart from the top plate, and a plurality of side plates extending from the top plate to the bottom plate. The top plate has a first thickness at a first location of the chassis frame to provide additional strength to the chassis frame at the first location. The top plate has a second thickness at a second location of the chassis frame to provide additional strength to the chassis frame at the second location.
