Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid diffuser devices in irrigation systems face challenges in controlling rotation speed for uniform jet distribution, suffer from significant atomization leading to evaporation losses, and are prone to irregular operation and blockages due to foreign bodies, especially in dusty environments.
Innovation Solution
A liquid diffuser device with a self-adjusting mechanism using an elastomeric braking member between the deflecting stem and hollow body, which automatically adjusts rotation speed based on jet pressure and flow rate, eliminating the need for complex gear systems and preventing impurity buildup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a gear assembly is used to drive rotation, then rotation speed can be controlled, but device complexity and cost increase
Solution Approach 1:
The patent removes the complex gear assembly from the system entirely. Instead of using gears to drive rotation, the invention uses a simple deflecting plate that redirects the water jet to create rotation through reaction force, thereby eliminating mechanical complexity while maintaining rotation control
Solution Approach 2:
The system uses the water jet itself to both drive rotation and control speed. The deflecting plate redirects the jet to create rotational motion, and by adjusting the deflection angle, the rotation speed is automatically controlled without requiring external mechanical control systems
2Ease of operation
If the hollow body is open to allow rotation, then the deflecting plate can rotate freely, but foreign bodies infiltrate and cause blockage
Solution Approach 1:
The patent introduces a flexible membrane that covers the opening of the hollow body while allowing the deflecting plate to rotate freely. This membrane acts as a barrier against foreign bodies like sand and dust, preventing infiltration into the rotation mechanism while maintaining operational freedom
Solution Approach 2:
The membrane serves as an intermediary element between the external environment and the internal rotation mechanism. It selectively blocks foreign bodies while permitting the passage of water and the rotation of the deflecting plate, thus protecting the system without restricting its function
3Area of stationary object
If the deflecting plate rotates quickly, then water distribution coverage increases, but atomization and evaporation loss increase
Solution Approach 1:
The patent implements dynamic control of the deflecting plate's rotation speed based on operational conditions. The system can adjust the rotation speed to optimize the balance between distribution coverage and droplet integrity, preventing excessive atomization that leads to evaporation loss while maintaining adequate coverage area
