Harvester Row Divider Lights for In-Field Parameter Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of agricultural harvesters face inefficiencies, losses, and strain due to the need to monitor operating parameters, which distracts them from the harvesting operation.
Innovation Solution
A system and method that utilizes light-emitting devices on row dividers of a harvesting implement to provide visual notifications of operating parameters, allowing operators to maintain focus on the field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the operator monitors operating parameters using traditional display systems, then parameter information can be obtained, but the operator's focus is diverted from the field, reducing harvesting efficiency and increasing fatigue
Solution Approach 1:
The patent transitions parameter information display from the traditional interior cabin display dimension to the exterior field-of-view dimension by mounting light-emitting devices on the harvesting implement. This spatial relocation allows the operator to monitor parameters without diverting attention from the harvesting operation, directly resolving the contradiction between parameter monitoring and harvesting efficiency
Solution Approach 2:
The patent introduces light-emitting devices as an intermediary medium between the operating parameters and the operator. These devices visually encode parameter status (normal, warning, critical) through color and pattern changes, enabling indirect parameter monitoring that does not require the operator's direct visual attention, thus maintaining harvesting productivity
2Reliability
If the operator frequently checks operating parameters, then parameter status can be verified, but operator strain and fatigue increase
Solution Approach 1:
The patent implements a continuous feedback mechanism where light-emitting devices on the harvesting implement provide real-time visual status information about operating parameters. The system automatically adjusts light patterns based on parameter conditions, creating a closed-loop feedback system that eliminates the need for repeated manual checks and reduces operator cognitive load and fatigue
Solution Approach 2:
The patent enables the harvesting implement to self-communicate its operational status to the operator through visually distinct light patterns. The system serves itself by automatically displaying parameter status without requiring operator intervention or attention, thereby reducing strain and fatigue while maintaining reliable parameter verification
