Multicolor Lighting Status Indicator for Autonomous Agricultural Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous agricultural vehicles lack a reliable method to indicate their operating state to nearby workers, as they do not have an onboard operator to acknowledge their presence or impending operations, posing safety risks.
Innovation Solution
A multicolor lighting assembly with a controller that selects status indications based on the vehicle's operating state, emitting specific light patterns and colors to inform workers of the vehicle's status, complemented by an audio system for visual and auditory alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous agricultural vehicles operate without an onboard operator, then automation level increases, but safety decreases due to inability to acknowledge worker presence
Solution Approach 1:
The patent introduces an intermediary communication system consisting of visual lights and audio signals that mediate between the autonomous vehicle and nearby workers. This intermediary allows the vehicle to convey its operational state and warnings without requiring direct human interaction or acknowledgment, thus maintaining automation while improving safety.
2Device complexity
If no status indication system is provided, then device complexity decreases, but information communication to workers deteriorates
Solution Approach 1:
The patent employs color changes in visual lights to communicate different operational states of the autonomous vehicle. Different colors indicate different statuses such as working, idle, or warning states, providing clear information communication to workers without requiring complex display systems or interfaces.
3Loss of information
If multiple status indications are implemented, then information communication improves, but device complexity increases
Solution Approach 1:
The patent implements a multi-functional lighting and audio system where the same physical components serve multiple purposes. The visual lights provide both status indication and warning functions, while the audio system delivers both informational messages and alerts. This universal approach enables comprehensive information communication without proportionally increasing device complexity.

AI summary
An indicator system for an autonomous agricultural vehicle includes a multicolor lighting assembly. The indicator system includes a controller comprising a memory operatively coupled to a processor. The processor is configured to select a status indication from a plurality of status indications that corresponds to a current operating state of a plurality of operating states. The processor is configured to output a second signal indicative of instructions to control the multicolor lighting assembly based on the status indication. The multicolor lighting assembly emits a light in response to the second signal.
