Steerable Trailer With Adjustable Traction Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural carts lack flexibility in carrying different types of inputs and operating under varying conditions, requiring multiple implements and increased inventory for farmers and dealers.
Innovation Solution
A modular trailer design with interchangeable containers, adjustable traction devices, and a steering mechanism, allowing for flexible operation in row cropping applications, and the ability to convert between steerable and non-steerable modes, with features like adjustable transverse distance and height for accommodating various agricultural implements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a trailer is designed for a specific application with fixed components, then it provides structural simplicity and ease of manufacture, but it lacks flexibility and adaptability for different agricultural inputs and operating conditions
Solution Approach 1:
The trailer is divided into separable components including interchangeable containers, adjustable traction devices, and configurable frame members. This segmentation allows each component to be independently selected or modified based on specific application requirements, enabling flexibility without requiring complete redesign of the entire system.
Solution Approach 2:
The trailer incorporates adjustable and convertible features such as height-adjustable frame members, transverse distance-adjustable traction devices, and steerable/non-steerable conversion capability. These dynamic elements allow the trailer to adapt its configuration to different operational conditions while maintaining a relatively simple base structure.
2Adaptability or versatility
If multiple specialized implements are purchased to handle different agricultural applications, then each implement is optimized for its specific function, but it increases inventory requirements and costs for farmers and dealers
Solution Approach 1:
The trailer is designed as a universal platform capable of performing multiple agricultural functions through interchangeable containers (for different inputs like seed, fertilizer, chemical), adjustable traction devices (for different ground conditions), and configurable frame members (for different towing applications). This multi-functionality allows a single trailer to replace multiple specialized implements, reducing inventory requirements.
3Measurement precision
If the trailer includes a steering mechanism for row cropping applications, then it provides improved tracking and operational precision, but it increases device complexity and converts it from a simple towable cart to a more complex steerable trailer
Solution Approach 1:
The steering mechanism is designed as an optional dynamic addition that can be integrated into the trailer's existing structure. The steering components connect to the tongue and frame members, allowing the trailer to switch between steerable and non-steerable modes based on application requirements, providing precision tracking when needed without permanently increasing base complexity.

AI summary
A trailer has a frame having frame-members configured to support a container, at least a pair of traction devices rotatably mounted on the frame, and a tongue configured to be mounted on a transportation device or an implement being towed by a transportation device. The frame-members may have a three-point mount configured to support a container. The container may be configured to be interchangeable with another container. The container may be an element of a seeding apparatus, the seeding apparatus mountable on the frame-members of the frame. The trailer may have a steering mechanism for the traction devices, and may be convertible between steerable and non-steerable modes. The steering mechanism may be guidance controlled. A transverse distance between the traction devices may be adjustable and/or height of the frame in relation to the ground may be adjustable. The trailer provides greater flexibility of operation under a greater variety of conditions.
