Solution Overview

Problem

The haymaking process faces a challenge in balancing the need to dry crop material to prevent mold and spoilage while minimizing handling that damages the material and reduces nutritional value, as excessive handling can compromise the crop's nutritional quality, especially in dry regions.

Innovation Solution

A crop management system utilizing field sensors to detect moisture content at multiple locations, transmitting data to a central processor for mapping, which determines the specific areas needing tedding, raking, and baling, allowing for targeted handling to maximize nutritional value and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If crop material is handled extensively through tedding and raking to ensure thorough drying, then the crop material dries adequately to prevent mold and spoilage, but the handling damages individual strands and removes leaves, reducing nutritional value

Engineering Contradiction:
Improvedrying adequacyVSAvoidnutritional value
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The system implements spatially differentiated handling by dividing the field into multiple zones based on moisture content measurements. Each zone receives tedding or raking operations only if its moisture level exceeds the threshold, allowing dry areas to remain undisturbed while wet areas receive necessary handling. This local quality approach ensures that handling is applied selectively rather than uniformly across the entire field.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The field is segmented into multiple discrete zones based on moisture content data collected from sensors positioned throughout the area. The data processor divides the field into zones requiring handling and zones that do not, enabling independent treatment of each segment. This segmentation allows the system to optimize handling operations for each zone individually, preventing unnecessary damage to already-dry crop material.

Inventive Principle:
Principle #1Segmentation

2Loss of substance

If crop material is handled minimally to preserve nutritional value, then less damage occurs to strands and leaves, but the crop material may not dry sufficiently, leading to mold and spoilage

Engineering Contradiction:
Improvenutritional valueVSAvoiddrying adequacy
Core Design Contradiction:
Loss of substanceVSReliability

Solution Approach 1:

The system continuously monitors moisture content in each field zone using sensor data and uses this feedback to dynamically adjust handling operations. The data processor compares real-time moisture measurements against target thresholds and automatically determines which zones require tedding or raking. This closed-loop feedback mechanism ensures handling is applied only when and where moisture levels indicate it is necessary, optimizing both drying adequacy and nutritional preservation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary moisture assessment across the entire field before initiating any handling operations. By measuring moisture content in advance and mapping spatial variations, the system can pre-identify zones that will require handling versus those that will not. This preliminary action allows operators to plan and execute handling operations efficiently, avoiding unnecessary interventions in zones that are already sufficiently dry.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the entire field is processed uniformly for drying, then all crop material has equal opportunity to dry, but time and resources are wasted on areas that are already dry

Engineering Contradiction:
Improvedrying uniformityVSAvoidprocessing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system applies different drying strategies to different spatial locations based on their specific moisture conditions. Rather than uniform processing, each zone receives handling operations tailored to its moisture level. This local quality approach ensures that dry areas are not subjected to unnecessary handling while wet areas receive appropriate attention, optimizing both drying uniformity across the field and overall processing efficiency.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system applies handling operations partially, only to the extent necessary for each zone's drying needs. By using moisture threshold criteria, the system determines the minimum required handling for each area, avoiding excessive action in already-dry zones. This partial action approach maintains adequate drying where needed while eliminating wasteful processing in areas that have already achieved sufficient dryness.

Inventive Principle:
Principle #16Partial or excessive action
