Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural systems lack an efficient method for manually overriding automated distance control in material transfer vehicles, leading to potential misalignment during unloading operations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated ground distance control system is used to automatically control the propulsion system, then productivity is improved through automation, but ease of operation deteriorates when manual intervention is needed for misalignment correction
Solution Approach 1:
A manual override actuator serves as an intermediary between the operator and the automated ground distance control system. When the operator actuates this device, it temporarily suspends automated control and directly controls the propulsion system to move the material transfer vehicle a predetermined distance, enabling quick manual intervention without complex procedures
Solution Approach 2:
The control system dynamically switches between automated mode and manual override mode based on operator input. The automated ground distance control system normally operates autonomously to maintain high productivity, but can be quickly transitioned to manual control when misalignment is detected, and then returned to automated mode after correction
2Device complexity
If automated ground distance control system operates without manual override capability, then device complexity is reduced, but manufacturing precision deteriorates due to inability to correct misalignment
Solution Approach 1:
The manual override actuator functions as a simple intermediary device that adds minimal complexity to the automated system. It provides a straightforward manual intervention mechanism that operators can use to correct positioning errors without requiring complex control algorithms or multiple control systems
Solution Approach 2:
The system changes the control parameter from fully automated to manual override when the actuator is engaged. This parameter change allows the system to switch between precision automated control and simple manual adjustment, enabling correction of positioning errors while maintaining overall system simplicity
3Ease of operation
If manual override actuator is added to the automated control system, then ease of operation is improved for misalignment correction, but device complexity increases
Solution Approach 1:
The manual override actuator is designed as a standalone intermediary component that interfaces with the existing automated control system. It provides manual intervention capability through a simple actuation mechanism that triggers predetermined actions in the propulsion system, adding minimal structural complexity while maximizing operational ease
Solution Approach 2:
The manual override actuator is pre-configured with predetermined movement distances and control parameters. When actuated, it immediately executes the pre-programmed action without requiring complex real-time calculations or adjustments, simplifying the overall control system structure while providing effective manual override capability

AI summary
An automated ground distance control system automatically controls a propulsion vehicle to travel a desired distance. Operator actuation of a manual override actuator is detected. Based on the detected actuation, the automated ground distance control system controls the propulsion vehicle to move a manual override distance. In one example, a configuration system exposes an operator interface for configuring the value of the manual override distance.
