Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current circular sprinkler irrigation machines face issues with entanglement of water and electric power lines during rotation, leading to inefficient and imprecise irrigation and spraying of water, fertilizer, and pesticide.
Innovation Solution
A circular sprinkler irrigation all-in-one machine integrates a sprinkler irrigation frame with a storage pesticide box, a water pipeline, and an electric power line, using a rotating mechanism and control panel to ensure continuous and precise spraying of water, fertilizer, and pesticide without entanglement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If water pipeline and electric power line are directly hung at the bottom of sprinkler irrigation machine, then spraying function is added, but lines become entangled during rotation preventing continuous operation
Solution Approach 1:
The patent introduces a retractable line spool as an intermediary device between the water pipeline/electric power line and the spraying mechanism. The spool allows lines to be paid out during extension and retracted during rotation, mediating the conflict between needing long lines for spraying reach and needing compact configuration during rotation. This enables continuous rotational operation while maintaining spraying capability.
2Adaptability or versatility
If additional separate spraying equipment is added to sprinkler irrigation machine, then water, fertilizer and pesticide spraying capability is achieved, but device complexity increases and usage efficiency decreases
Solution Approach 1:
The patent merges the spraying function with the existing sprinkler irrigation machine by integrating the water pipeline, electric power line, and spray nozzles into a unified system. The spray nozzles are mounted on the existing machine structure, and the water pipeline is integrated with the irrigation system, eliminating the need for separate spraying equipment. This reduces device complexity while maintaining multifunctionality.
3Measurement precision
If spray irrigation tube is extended to reach crops, then spraying precision is improved, but line length increases causing entanglement during rotation
Solution Approach 1:
The patent employs a retractable line spool that dynamically adjusts line length during operation. During spraying setup, the line is paid out to achieve precise positioning of spray nozzles near crops. During rotation, the line is automatically retracted to prevent entanglement. This dynamic adjustment of line length resolves the contradiction between needing long lines for precision and short lines for rotation.
