Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural vehicle frame structures do not support the mounting of interchangeable fuel tanks and alternative energy systems, limiting their adaptability and operational autonomy, and lack maneuverability due to fixed designs.
Innovation Solution
A spatial frame structure with interconnected longitudinal beams, transverse and diagonal pipes, and stiffening elements allows for the connection of interchangeable fuel tanks and alternative energy systems, providing additional space and enhanced maneuverability through a narrow front chassis with electric drive and high steering angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed frame structure design is used, then structural simplicity is maintained, but adaptability for interchangeable fuel tanks and alternative energy systems is limited
Solution Approach 1:
The frame structure is divided into multiple horizontal structures (upper, middle, lower) with multiple attachment points, allowing different components to be mounted on different segments. This segmentation enables the frame to accommodate various configurations of fuel tanks and alternative energy systems without requiring a completely different frame design.
Solution Approach 2:
The frame structure is designed with universal attachment capabilities across all horizontal structures, allowing the same frame to support multiple functions including traditional fuel tanks, interchangeable fuel tanks, and alternative energy systems. The multiple attachment points and structured design provide universal mounting options for diverse components.
2Duration of action of moving object
If traditional frame designs are used, then manufacturing simplicity is maintained, but operational autonomy and working time are limited
Solution Approach 1:
The frame utilizes three-dimensional spatial arrangement with upper, middle, and lower horizontal structures, creating multiple levels for component placement. This dimensional approach allows fuel tanks and energy systems to be positioned in previously unused spatial zones, increasing operational capacity without complicating the basic manufacturing process.
3Ease of operation
If a standard chassis width is used, then structural stability is maintained, but maneuverability and steering angle are reduced
Solution Approach 1:
The frame structure implements different design characteristics at different locations: the front part features a narrowed width to improve steering angle and maneuverability, while the rear and side portions maintain sufficient width and structural elements to ensure stability. This local differentiation allows the chassis to optimize both maneuverability and stability in their respective zones.
4Volume of moving object
If components are mounted inside the frame, then space utilization is improved, but access for maintenance and repair becomes difficult
Solution Approach 1:
The frame's horizontal structures are designed with multiple attachment points and open configurations that allow components to be mounted in accessible positions. Rather than enclosing all components within the frame, the segmented structure provides access points throughout, enabling maintenance personnel to reach components without disassembling the entire frame.
Solution Approach 2:
The horizontal structures serve as intermediary mounting platforms that position components in optimal locations - neither completely inside nor outside the frame - providing both space utilization and accessibility. These structures act as intermediate mounting surfaces that balance the competing requirements of compact arrangement and easy access.

AI summary
This description describes the spatial frame structure of a vehicle designed for connecting structural assemblies. The described frame construction differs from the analogues in that it allows the use of interchangeable high-capacity fuel tanks. As a result, most structural assemblies are mounted to the outside of the frame, thus creating additional space in which elements of alternative fuel and energy source systems (e.g. natural gas tanks, electric batteries) can be assembled. This makes it possible to increase the working time of the agricultural vehicle. The frame construction consists of rigidly interconnected longitudinal tubular beams, transverse, perpendicular and diagonally arranged structural pipes, additionally connecting stiffness elements. The structure includes fastening elements for connecting the following structural assemblies: rear wheel hubs, which are assembled with electric drives; mechanical implement coupling device; structure of replaceable fuel tanks; door platform; folding driver's cab; chassis steering axle with electric drive; side component containers; power plant; mechanical coupling device for trailers and semi-trailers.
