Remote Control Motion Activated Sprinkler with Cam Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motion-activated water repellant sprinkler devices require manual adjustment of sensitivity settings and deactivation, which is inconvenient and can be difficult to manage due to the risk of being sprayed.
Innovation Solution
A remotely controlled motion-activated water repellant sprinkler device with a motor and cam valve control system that uses infrared signals for remote operation, allowing for adjustable sensitivity settings and indefinite or timed operation, reducing the need for manual intervention and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of sensitivity settings is used, then the device can be configured to desired sensitivity, but the user must physically approach the device which risks being sprayed
Solution Approach 1:
A remote control unit serves as an intermediary between the user and the sprinkler device. The remote control allows sensitivity settings to be adjusted without the user physically approaching the device, thereby eliminating the risk of being sprayed while maintaining the ability to configure the device to desired sensitivity levels
2Ease of operation
If manual deactivation is used, then the device can be turned off, but the user must approach the device which risks being sprayed
Solution Approach 1:
The remote control unit acts as an intermediary that enables device deactivation without requiring the user to physically approach the sprinkler. Users can safely deactivate the device from a distance, eliminating the spray risk associated with manual deactivation
3Duration of action of stationary object
If continuous operation is used, then the sprinkler can water plants indefinitely, but power consumption increases
Solution Approach 1:
The system dynamically adjusts operation mode based on user needs through remote control. It can switch between motion-activated mode (lower power consumption) and continuous sprinkler mode (higher power consumption but indefinite operation). This dynamic capability allows users to optimize the balance between operation duration and power consumption based on specific requirements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient remote control of sensitivity settings and deactivation, reducing the risk of being sprayed and lowering power requirements, making the device more user-friendly and efficient.
Implementation Method 1
a motor and cam valve control system in which the motor rotates the cam to open and close a water control flow valve
Implementation Method 2
the magnet pulls back a metal plunger in the water flow control valve to open the valve

AI summary
A motion activated water repellant sprinkler device for repelling animals that can be remotely controlled is provided. When the device is in on mode, the user can remotely adjust the sensitivity setting of the motion detector, set a time period for which the sprinkler will continually spray, and turn off the device so that the user can approach the device without being sprayed. The ability to set a particular time period for continuous sprinkler activity allows the motion activated water repellant sprinkler device to be used not only as an animal deterring device but also as a watering device for grass and other plants.
