Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pest control vehicles face instability in chemical liquid spraying due to wind direction and uneven distribution on crop leaves, leading to uneven application.
Innovation Solution
The vehicle incorporates cylindrical members with chemical liquid and air passages, along with injection and blower devices, to support the spraying of chemical liquids, ensuring uniform distribution and a compact structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical liquid is sprayed using conventional nozzle units, then the spraying system is simple, but the spraying distance to crop leaves is unstable and chemical liquid is ununiformly sprayed due to wind impact
Solution Approach 1:
Air is introduced as an intermediary substance to support and stabilize the chemical liquid spray. The air injection portions inject air to support the chemical liquid to be sprayed, creating a more stable spray pattern that is less affected by wind conditions.
Solution Approach 2:
The invention uses pneumatic principles by introducing air flow through air passages and air injection portions to support the chemical liquid spray. This pneumatic support stabilizes the spray distance and distribution on crop leaves.
2Manufacturing precision
If air injection portions and air passages are added to support chemical liquid spraying, then spraying uniformity is improved, but device complexity increases
Solution Approach 1:
The cylindrical member integrates multiple functions into a single component: it serves as both the structural housing and contains internal chemical liquid passages and air passages. The chemical liquid injection portions and air injection portions are combined in the same cylindrical structure, reducing the number of separate components.
Solution Approach 2:
The cylindrical member performs multiple functions simultaneously: it stores chemical liquid, guides chemical liquid flow through passages, introduces air through separate passages, and provides structural support for the spray system. This multi-functionality reduces overall system complexity.
3Device complexity
If chemical liquid ducts are extended to cover both left and right injection portions, then the number of ducts is reduced, but the device becomes less compact and more complex
Solution Approach 1:
The spray system is divided into separate left and right chemical liquid ducts, each serving specific injection portions. This segmentation allows for more compact arrangement and easier routing of ducts compared to a single extended duct covering all injection portions.

Function Achieved in This Case
This configuration allows for stable and uniform spraying of chemical liquids over a wider area, enhancing the effectiveness of pest control while maintaining a compact design.
Implementation Method 1
Air flows through the air passage. The air injection portions are connected to the air passage and inject the air to support the chemical liquid to be sprayed.
