Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If collapsed grain culm detection is performed during harvesting, then harvesting work control can be adjusted, but the detection information cannot be utilized for future farming plans

Engineering Contradiction:
Improveharvesting work efficiencyVSAvoiddetection information utilization
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The system performs preliminary detection of collapsed grain culms during harvesting and stores the spatial distribution information in advance. This allows the information to be reused for future farming plan creation without requiring additional detection operations, thus preventing information loss while maintaining harvesting efficiency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates a digital copy (spatial distribution map) of the collapsed grain culm detection information during harvesting. This copied information can then be stored and reused for multiple farming plans without losing the original detection data, enabling both harvesting control and future agricultural decision-making.

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If spatial distribution mapping of collapsed grain culms is implemented, then farming plan optimization becomes possible, but system complexity increases

Engineering Contradiction:
Improvefarming plan adaptabilityVSAvoidinformation processing system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spatial distribution mapping system serves multiple functions: it enables harvesting work control, supports creation of various farming plans (fertilizer application, planting density adjustment), and provides historical data for analysis. This multi-functionality justifies the system complexity by delivering diverse agricultural benefits from a single information processing framework.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system introduces a spatial distribution map as an intermediary data structure that bridges harvesting detection information and farming plan creation. This intermediary layer simplifies the complexity by providing a standardized format that can be easily processed for different farming scenarios without requiring complex direct transformations between detection data and various plan types.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If detailed produce evaluation per unit traveling is performed, then yield and taste value distribution can be confirmed, but measurement and processing complexity increases

Engineering Contradiction:
Improveproduce evaluation precisionVSAvoidproduce quality measurement difficulty
Core Design Contradiction:
Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The system divides the field into discrete measurement segments corresponding to unit traveling distances of the combine. By evaluating produce quality in these segmented units rather than as a whole, the system achieves precise spatial distribution mapping of yield and taste values while making the measurement process manageable through systematic breakdown.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The produce evaluation is performed continuously during harvesting operations at unit traveling intervals. This continuous measurement approach maintains high precision by capturing spatial variations without interruption, while the automated nature of continuous measurement during normal harvesting reduces the practical difficulty compared to discrete sampling methods.

Inventive Principle:
Principle #20Continuity of useful action
