Overhead Display with Multi-Color Indicators for Agricultural Machine State Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monitoring various system states on modern agricultural sprayers is challenging due to the complexity and distribution of system information, requiring operators to navigate multiple display menus, which is time-consuming and distracting.
Innovation Solution
A front overhead display panel with multicolor indicators in the operator cab allows quick monitoring of machine functions while maintaining a forward view, using a display controller to illuminate indicators with specific colors corresponding to activation, deactivation, or susceptibility states of components like spray sections, pumps, and steering modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If operators monitor system states through multiple display menus, then comprehensive system information is available, but operator attention is diverted from the field and monitoring time increases
Solution Approach 1:
The patent extracts critical system state information from complex multi-menu displays and presents it in a simplified overhead indicator format. Key functions like spray section status, boom position, and system alerts are pulled out and displayed as immediate visual indicators above the operator's field of view, eliminating the need to navigate through multiple menus while maintaining comprehensive monitoring capability
Solution Approach 2:
The patent transitions from a two-dimensional menu-based display requiring operator interaction to a three-dimensional overhead display positioned above the operator's field of view. This spatial repositioning allows information to be presented in the operator's peripheral vision without requiring attention shifts, effectively adding a spatial dimension to information delivery that resolves the time-loss contradiction
2Loss of information
If operators navigate through multiple display menus to find system state information, then detailed information can be accessed, but operator distraction and time consumption increase
Solution Approach 1:
Critical system state information is extracted from complex menu structures and presented as immediate visual indicators. The overhead display pulls out essential status information (spray section activation, boom position, system alerts) and presents it in a simplified format that requires no navigation or interaction, dramatically improving ease of operation while maintaining information completeness
Solution Approach 2:
The patent repositions the display from a horizontal menu interface requiring operator attention and navigation to a vertical overhead display positioned above the field of view. This dimensional change places information in the operator's peripheral vision, allowing monitoring without attention shifts or complex operations, thereby resolving the ease of operation contradiction
3Reliability
If multiple display menus are used to show system states, then comprehensive monitoring is possible, but operator focus on the field is reduced
Solution Approach 1:
The patent positions the display vertically above the operator's field of view rather than horizontally in the operator's direct line of sight. This spatial repositioning places monitoring information in the operator's peripheral vision, allowing comprehensive system monitoring to occur without requiring the operator to shift attention from the field, thereby resolving the contradiction between monitoring reliability and operator focus
Solution Approach 2:
The patent extracts essential monitoring functions from complex menu systems and presents them as immediate visual indicators in the overhead display. By pulling out critical status information (spray section status, system alerts, boom position) and presenting it in a simplified format, the system maintains reliable monitoring capability while eliminating the need for operator attention shifts
4Loss of information
If comprehensive system information is distributed across multiple locations, then detailed monitoring is achieved, but information accessibility increases complexity
Solution Approach 1:
The patent merges multiple distributed information sources into a single consolidated overhead display location. Instead of having system state information scattered across multiple menus and display locations, the overhead indicator integrates spray section status, boom position, system alerts, and other critical information into one unified view directly above the operator's field of view, reducing display system complexity while maintaining information completeness
Solution Approach 2:
The patent extracts essential system state information from distributed menu systems and consolidates it in the overhead display. By pulling out critical status indicators from various menu locations and presenting them in a unified overhead format, the system reduces the complexity of information accessibility while maintaining comprehensive monitoring capability

AI summary
A front overhead display panel can be configured in an operator cab of an agricultural machine so that an operator can quickly monitor current states of multiple functions of the machine while maintaining a forward view of the agricultural field. The display panel can include multiple multicolor indicators with each multicolor indicator corresponding to a function of the machine. A display controller can monitor current states of the functions and illuminate the indicators with select colors corresponding to the states. States can include activation, deactivation and/or susceptibility to machine control. Functions can include control with respect to spray sections, product pumps, rinse systems, steering modes, and the like.
