Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UAV plant protection methods for fruit crops are labor-intensive, prone to manual errors, and inefficient due to the complexity of fruit tree topography, leading to incomplete spraying and increased costs.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual and remote control mode is used for fruit tree spraying, then the UAV can operate in complex environments, but labor cost increases and operational efficiency decreases
Solution Approach 1:
The UAV autonomously navigates to target fruit trees using GPS coordinates, automatically adjusts flight height based on tree height data, and controls spraying operations without continuous manual intervention. The system self-manages the complete spraying task from navigation to dosage control, eliminating the need for full manual participation while maintaining adaptability to complex orchard environments
Solution Approach 2:
The system pre-acquires mapping information including tree locations, heights, and spray radii before operation. GPS coordinates of target trees are predetermined and stored, allowing the UAV to automatically navigate and execute spraying tasks without real-time manual guidance, thus improving efficiency while maintaining environmental adaptability
2Ease of operation
If manual control is used for fruit tree spraying, then the operator can adjust to different tree conditions, but manual errors increase and spray coverage becomes incomplete
Solution Approach 1:
The system uses pre-acquired mapping information including tree height and position data to automatically adjust flight parameters and spray dosage. The UAV receives feedback from GPS location and altitude sensors to maintain precise positioning and consistent spray coverage, eliminating manual errors while preserving operational flexibility through automated decision-making
Solution Approach 2:
Manual mechanical control is replaced with automated electronic control systems. The UAV uses electronic navigation based on GPS coordinates and automated flight control based on pre-acquired tree data, substituting human manual operation with electronic systems that provide more consistent and reliable spray coverage
3Manufacturing precision
If line-by-line scanning spraying is used for flat farmlands, then precise spraying can be achieved, but the method cannot be applied to fruit trees with complex topography
Solution Approach 1:
The system dynamically adjusts the spraying approach based on the target object. For fruit trees, it transitions from fixed line-by-line scanning to flexible spiral flight patterns centered on each tree, with dynamic adjustment of flight height based on real-time tree height data from mapping information, maintaining spray precision across different crop types
Solution Approach 2:
The system changes flight parameters including path pattern (from linear to spiral), flight height, and spray radius based on the specific characteristics of the target crop. Mapping information provides tree-specific parameters that are used to customize the spraying operation, enabling the same UAV system to precisely spray both flat field crops and three-dimensional fruit trees
