Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current grain cart systems lack autonomous capabilities for efficient unloading and relocation, leading to increased harvesting time and productivity losses due to manual operation and limited mobility in challenging field conditions.
Innovation Solution
A system comprising a cart equipped with sensors, vehicle components, and computers that enable autonomous operation, including obstacle detection, route navigation, and automated unloading, allowing the cart to move between unloading locations and adjust the auger assembly for efficient grain discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used for cart unloading and relocation, then device complexity is reduced, but productivity decreases and harvesting time increases
Solution Approach 1:
The cart system performs autonomous navigation, obstacle detection, and unloading operations without requiring manual intervention. The computer coordinates vehicle components to move the cart between unloading locations, and sensors enable autonomous obstacle detection and avoidance, allowing the system to serve itself and dramatically improving productivity
Solution Approach 2:
Manual mechanical operation is replaced with an automated control system comprising a computer, sensors, and vehicle components. The computer processes sensor data and controls vehicle components to automate navigation and unloading, substituting human-operated mechanical systems with electronically-controlled automated systems that enhance productivity
2Loss of time
If the cart remains at a single unloading location, then device complexity is reduced, but loss of time increases due to inability to serve multiple containers
Solution Approach 1:
The cart transitions from a static position at a single unloading location to dynamic movement between multiple unloading locations. The system uses sensors and a computer to dynamically navigate to different containers, enabling the cart to serve multiple containers sequentially and reducing overall harvesting time without excessive complexity
Solution Approach 2:
The cart is designed to perform multiple unloading operations at different locations rather than being dedicated to a single location. The navigation system and sensor suite enable the cart to universally serve multiple containers, making the system multi-functional and reducing time loss by eliminating idle travel time between harvest and unloading
3Reliability
If obstacle detection is not implemented, then device complexity is reduced, but reliability decreases in challenging field conditions
Solution Approach 1:
Sensors continuously monitor the environment around the cart and provide feedback to the computer. The computer processes this feedback information and adjusts navigation and unloading operations accordingly, enabling reliable operation in challenging field conditions by detecting and responding to obstacles and environmental changes in real-time
Solution Approach 2:
Sensors act as intermediary elements between the cart and the field environment. These sensors detect obstacles, terrain conditions, and container positions, translating physical environmental information into data that the computer can process, thereby enhancing operational reliability without requiring direct complex interaction between the cart and challenging field conditions

AI summary
Systems and methods for automated cart operation. The automated cart operation may include determining whether a container is full at a first unloading location and, if so, moving the cart from the first unloading location to a second unloading location. The automated cart operation may include moving the cart to a container, determining whether the cart is near the container, and, if the cart is determined to be near the container, stopping the cart. The automated cart operation may include determining a route from a current location to the location of a farm implement that avoids one or more permanent obstacles and areas of the field that have not been harvested and moving the cart to the farm implement on the determined route.
