Solution Overview

Problem

Existing distribution machines in agriculture, such as precision seed drills, face challenges in visual control of their components due to strong reflections from halogen headlights, making it difficult for operators to assess the functionality from a distance, especially in low light conditions, and are inefficient in illumination.

Innovation Solution

The lighting characteristic of at least one light source is changed, including color and flashing frequency, to provide direct feedback on the operating status of components, with LED light sources being used for efficient illumination, and sensors to automatically switch lights on and off based on brightness, ensuring clear visibility of dosing and dispensing elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the entire machine is illuminated by powerful halogen headlights, then all parts of the machine can be recognized, but the components to be observed in detail are not particularly easy to recognize due to strong reflections and it is uneconomical

Engineering Contradiction:
Improveillumination of machine componentsVSAvoidlight reflection
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by illuminating only specific components (dosing elements, centrifugal discs, throwing vanes) rather than the entire machine. This targeted approach reduces overall light intensity requirements and minimizes harmful reflections from non-critical areas while ensuring sufficient illumination where observation is needed.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The illumination system is segmented into multiple independent light sources, each assigned to illuminate specific components. This allows selective illumination of dosing elements, centrifugal discs, and throwing vanes independently, enabling operators to focus on critical components without being overwhelmed by reflections from the entire machine structure.

Inventive Principle:
Principle #1Segmentation

2Illumination intensity

If the entire machine is illuminated by powerful halogen headlights, then all parts of the machine can be recognized, but it is uneconomical to illuminate and/or illuminate the entire machine with high-intensity lamps

Engineering Contradiction:
Improveillumination of machine componentsVSAvoidenergy consumption of lighting system
Core Design Contradiction:
Illumination intensityVSUse of energy by stationary object

Solution Approach 1:

The patent implements local quality by directing illumination only to specific components that require observation (dosing elements, centrifugal discs, throwing vanes) rather than illuminating the entire machine. This localized approach significantly reduces the total energy consumption of the lighting system while maintaining adequate visibility of critical components.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The lighting system operates periodically rather than continuously, with lights being switched on only when observation of components is required and switched off when not needed. This periodic operation reduces overall energy consumption while ensuring adequate illumination when required for monitoring distribution processes.

Inventive Principle:
Principle #19Periodic action

3Illumination intensity

If traditional lighting is used, then components can be illuminated, but no clear statement can be made about the functionality of the machine from a distance due to ever-growing machines

Engineering Contradiction:
Improvevisibility of componentsVSAvoidvisual control from distance
Core Design Contradiction:
Illumination intensityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent employs color changes by using LEDs that can emit different colors (e.g., green for normal operation, red for faults) to indicate the operational status of components. This color-coding system enables operators to assess machine functionality from a distance without needing to approach closely or rely on subtle brightness variations alone.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The lighting system incorporates periodic flashing or pulsing patterns to enhance visibility from a distance. By modulating the light output in distinctive patterns, operators can detect component status and identify potential issues from greater distances, overcoming the limitation of large machine size that obscures detailed observation.

Inventive Principle:
Principle #19Periodic action

4Productivity

If material to be distributed is not visible from the outside during the distribution process, then no direct visual control of the distribution process is possible

Engineering Contradiction:
Improvedistribution process efficiencyVSAvoidvisual control of distribution
Core Design Contradiction:
ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent uses color-changing LEDs to provide visual feedback on the operational status of dosing elements and distribution components. Different colors indicate whether materials are being correctly fed and distributed, enabling operators to monitor the distribution process visually from a distance without needing to see the material itself.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The lighting system provides immediate visual feedback on the distribution process by illuminating and color-coding components based on their operational status. This feedback mechanism allows operators to detect issues with material feeding or distribution in real-time and take corrective action, maintaining productivity without direct visual access to the material flow.

Inventive Principle:
Principle #23Feedback
