Touchscreen Interlock for Intentional Autonomous Farm Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous agricultural systems lack a mechanism to prevent unintentional activation of controls, particularly on touchscreens, which can lead to accidental operation of agricultural vehicles and implements.
Innovation Solution
A control system with an interlock mechanism that disables manual controls on the touchscreen display, requiring a specific input, such as a swipe gesture or pressure threshold, to unlock and allow intentional operation, thereby preventing unintentional activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual controls are made easily accessible on the touchscreen display, then ease of operation is improved, but the risk of unintentional activation increases
Solution Approach 1:
The system applies preliminary anti-action by implementing an interlock mechanism that preemptively prevents unintentional activation before it can occur. The interlock control is configured to detect potential accidental inputs and block them from triggering control operations, thereby counteracting the harmful effect before it manifests.
Solution Approach 2:
The interlock control serves as an intermediary element between the user interface and the control operations. It acts as a mediator that must be satisfied or disengaged before control functions can be activated, thereby preventing direct and potentially accidental activation while still allowing intentional operation.
2Object-affected harmful factors
If an interlock mechanism is implemented to prevent unintentional activation, then safety is improved, but device complexity increases
Solution Approach 1:
The interlock control is designed to serve multiple functions: it acts as a safety mechanism to prevent unintentional activation, serves as a user interface element that can be configured with different input requirements, and functions as a control state indicator. This multi-functionality reduces the need for separate dedicated components.
Solution Approach 2:
The system implements self-service by allowing the interlock mechanism to automatically manage its own state based on detected inputs. The controller monitors the interlock control's state and automatically enables or disables control operations accordingly, without requiring additional manual intervention or complex external control systems.

AI summary
A control system (20) for an autonomous agricultural system (10) includes a display configured to display at least one control function associated with at least one operation. The display is configured to output a first signal indicative of a first input. The control system (20) includes a controller (24) comprising a processor (26) and a memory (28). The controller (24) is communicatively coupled to the display and configured to receive the first signal indicative of the first input and to send a second signal to the display indicative of instructions to display a second control in an unlocked state. The display is configured to output a third signal to the controller (24) indicative of the second input. The controller (24) is configured to receive the third signal and to output a fourth signal indicative of instructions to control the at least one operation of the autonomous agricultural system (10).
