Innovation Solution

An integrated recommendation method and system based on a knowledge graph that vectorizes salt-controlled irrigation and fertilization information, calculates similarity with soil conditions, and predicts a score for recommendations, optimizing fertilizer application and irrigation strategies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If mathematical models are used for fertilization planning, then fertilization amount can be calculated, but suggestions on fertilizer varieties and fertilization methods are not provided

Engineering Contradiction:
Improvefertilization amount calculationVSAvoidfertilizer variety and method suggestions
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent combines mathematical models with knowledge graphs to integrate quantitative fertilization amount calculation with qualitative recommendations on fertilizer varieties and application methods. The knowledge graph stores expert knowledge about different fertilizer types, application techniques, and best practices, which complements the numerical outputs from mathematical models.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system is designed to provide multiple functions: calculating fertilization amounts, recommending fertilizer varieties, suggesting application methods, and providing salt control advice. This multi-functional approach allows a single system to address all aspects of fertilization planning rather than requiring separate tools for each function.

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

2Ease of operation

If expert knowledge methods are used for fertilization planning, then suggestions on fertilization technology and fertilizer ratio are provided, but the system lacks integration with salt control and irrigation management

Engineering Contradiction:
Improvefertilization plan generationVSAvoidsalt control and irrigation integration
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent merges expert knowledge methods with salt control and irrigation management systems. The knowledge graph integrates information about fertilizer application with soil salinity data, irrigation schedules, and crop requirements, enabling comprehensive recommendations that consider all these factors together rather than in isolation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system provides universal applicability across different farming scenarios by integrating multiple functions: fertilization planning, salt control, irrigation management, and crop-specific recommendations. This allows the system to adapt to various soil conditions, crop types, and environmental factors within a single unified platform.

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

3Measurement precision

If artificial intelligence models are used for fertilization recommendation, then high-precision results are obtained, but the system lacks interpretability and integration with agricultural knowledge bases

Engineering Contradiction:
Improvefertilization recommendation accuracyVSAvoidinterpretability and knowledge integration
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The knowledge graph serves as an intermediary between AI models and agricultural practitioners. It structures and stores domain knowledge in a interpretable format, allowing AI predictions to be explained through references to known agricultural principles and relationships stored in the knowledge graph, thus bridging the gap between black-box AI and interpretable expert systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system combines the predictive power of AI models with the interpretability of knowledge-based systems. The knowledge graph enables the system to provide not only accurate recommendations but also explanations based on agricultural science principles, making the system both precise and interpretable simultaneously.

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

4Productivity

If traditional fertilization methods are used in saline-alkali lands, then crop yield may be maintained, but fertilizer utilization rate is low and environmental pollution increases

Engineering Contradiction:
Improvecrop yieldVSAvoidenvironmental pollution and soil degradation
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by providing site-specific fertilization recommendations tailored to the particular soil conditions, salinity levels, and crop requirements of each location. Rather than using uniform fertilization approaches, the system customizes recommendations based on local soil testing data and environmental factors, optimizing fertilizer use for each specific context.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts fertilization parameters such as fertilizer type, amount, timing, and application method based on real-time soil conditions, salinity levels, and crop growth stages. This parameter optimization ensures maximum fertilizer efficiency while minimizing environmental impact by applying the right amount at the right time rather than excessive uniform application.

Inventive Principle:
Principle #35Parameter changes
