Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sprinkler systems are not robust enough and are sensitive to environmental influences such as heat and precipitation, with known switching devices experiencing high wear and limited reliability.
Innovation Solution
A magnetic switching unit is used to hold the nozzle in stable switching positions, utilizing magnetic forces of attraction and a spring force to maintain bistable states, with a shift lever and actuating element designed for pivoting and a pawl mechanism to control the nozzle's rotation, allowing for robust operation and low sensitivity to environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional switching device with shift lever and actuating element is used, then the sprinkler can switch rotation direction, but the device experiences high wear and is sensitive to environmental influences
Solution Approach 1:
The patent replaces the traditional mechanical switching device with a magnetic switching mechanism. The shift lever and actuating element are replaced by magnetically actuated components that use magnetic fields to hold the nozzle in switching positions, eliminating mechanical wear and reducing sensitivity to environmental factors like heat and precipitation.
Solution Approach 2:
The patent changes the operating principle from mechanical contact-based switching to magnetic field-based switching. By using magnetic forces to hold the switching positions, the system achieves higher reliability and reduced sensitivity to environmental conditions while maintaining the same functional capability of switching rotation direction.
2Reliability
If a magnetic switching unit is used to hold the nozzle in stable switching positions, then reliability and robustness are improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical switching mechanisms with a magnetic switching unit that uses magnetic fields to hold switching positions. This substitution reduces the number of mechanical components and eliminates wear-prone contacts, achieving higher reliability without proportionally increasing complexity.
Solution Approach 2:
The magnetic switching unit utilizes magnetic forces to automatically hold the nozzle in switching positions without requiring additional actuating mechanisms. The magnetic fields provide self-sustaining holding force, eliminating the need for continuous mechanical actuation and reducing overall device complexity.
