Solution Overview

Problem

Current pesticide spraying methods are inefficient, requiring high manpower and equipment maintenance, wasting water, and face challenges in uniform application, pathogen transmission, and pesticide degradation, while unmanned helicopter systems struggle with uniform spraying and have short operational times.

Innovation Solution

An automatic agricultural machine with a fixed base, first-direction movement guide, and automatic spraying device that uses trigonometric principles and the Pythagorean theorem for controlled movement to ensure uniform pesticide application across irregular farmland areas, detect crop growth, and eradicate pests in real time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual pesticide spraying is used, then equipment cost is low, but productivity is low and water is wasted

Engineering Contradiction:

Improvespraying efficiencyVSAvoidwater waste

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

The patent replaces manual mechanical spraying with an automated system that uses sensors to detect crop conditions and environmental factors, then automatically controls the spraying mechanism. This substitution of manual operation with automated sensing and control systems improves both productivity and reduces water waste through precise application.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system dynamically adjusts spraying parameters such as water flow rate, spray timing, and target selection based on real-time sensor data about crop water needs, soil moisture levels, and environmental conditions. This parameter optimization ensures efficient water use while maintaining high productivity.

Inventive Principle:

Principle #35Parameter changes

2Area of stationary object

If sprinkler method is used, then large area can be covered, but equipment maintenance cost is high and pathogens are transmitted

Engineering Contradiction:

Improvecoverage areaVSAvoidequipment durability

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The patent divides the large coverage area into multiple zones, each equipped with independent spraying units that can operate autonomously. This segmentation allows the system to cover large areas while reducing the complexity and maintenance burden on individual equipment components, thereby improving reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system introduces sensor networks and control systems as intermediaries between the water source and the crops, enabling precise targeted spraying rather than blanket coverage. This reduces pathogen transmission by limiting water application to specific areas that need it, while still achieving large area coverage through coordinated operation of multiple units.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Duration of action of moving object

If unmanned helicopter is used, then operational time is extended, but spraying uniformity deteriorates and piloting difficulty increases

Engineering Contradiction:

Improveoperational timeVSAvoidspraying uniformity

Core Design Contradiction:

Duration of action of moving objectVSManufacturing precision

Solution Approach 1:

The patent replaces manual piloting of unmanned helicopters with automated ground-based or drone-based spraying systems that use computer-controlled mechanisms. This substitution eliminates the piloting difficulty and spraying uniformity problems associated with manual operation, while maintaining extended operational capability through automated system design.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Productivity

If automated system is introduced, then productivity increases, but device complexity increases

Engineering Contradiction:

Improvespraying efficiencyVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent designs the automated system with multi-functional components that perform multiple tasks. For example, sensor units detect both crop water needs and environmental conditions, while the control system manages both spraying operations and data analysis. This universality reduces overall system complexity while maintaining high productivity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
