Automatic Watering System with Float Refill Indicator and Gripping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic watering systems for plants do not efficiently indicate the present water level and are difficult to remove from larger containers, often requiring complex sensors and not providing a user-friendly setup.
Innovation Solution
An automatic watering system with a refill indicator that tracks the water level and includes gripping mechanisms for easy removal, eliminating the need for complex sensors and allowing for efficient water level indication and filling, while preventing water from entering the feed reservoir when the indicator is removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a refill indicator structure is added to indicate water level, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The refill indicator structure is self-activating through a float mechanism that automatically rises and falls with water level changes, eliminating the need for external power sources, sensors, or complex electronic components. The indicator serves itself by using the water's own buoyancy force to drive the indication mechanism.
Solution Approach 2:
The refill indicator is designed as a separate, removable component that can be extracted from the water storage reservoir. This modular approach allows the indicator to be removed for cleaning or replacement without disassembling the entire reservoir, simplifying maintenance while maintaining accurate water level indication during use.
2Adaptability or versatility
If the automatic watering system is positioned within another container, then adaptability is improved, but ease of operation worsens due to difficulty in removal
Solution Approach 1:
Gripping mechanisms are strategically positioned at specific locations on the exterior of the water storage reservoir, creating localized ergonomic features. These gripping areas provide enhanced friction and mechanical advantage at precise points, making removal easy without requiring structural changes to the entire container or compromising its adaptability to fit within various pots.
3Ease of operation
If the refill indicator is made removable to serve as a water filling port, then ease of operation is improved, but reliability worsens due to potential water leakage
Solution Approach 1:
A seal mechanism is pre-positioned within the refill indicator structure that automatically engages when the indicator is inserted into the water storage reservoir. This preliminary sealing action occurs before any water filling operation, ensuring the seal is already in place and preventing leakage throughout the filling process and subsequent use.
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
The system effectively indicates the water level and allows for easy removal from larger containers, providing a user-friendly setup without the need for costly sensors, ensuring efficient water management and maintenance.
Implementation Method 1
The air return conduit has a float valve for reversibly sealing the air return conduit
Implementation Method 2
The refill indicator may include a float body which tracks a level of water within the upper water storage reservoir
Implementation Method 3
The seal is coupled to a spring, which applies a force against the seal such that the seal closes the water feed reservoir upon rotating, moving, or removing the refill indicator
Data Source
AI summary
An automatic watering system includes a water storage reservoir and a water feed reservoir positioned elevationally below the water storage reservoir. The water feed reservoir has a plurality of water feed apertures aligned substantially horizontally for allowing water to pass from the water feed reservoir to outside of the water feed reservoir. The water feed reservoir is in fluid communication with the water storage reservoir via a water tube with a biased seal and via an air return conduit which has a float valve. The water storage reservoir is in fluid communication with the refill indicator for indicating a water level present within the water storage reservoir. The refill indicator includes a float body that tracks the water level within the water storage reservoir. The automatic watering system may also include a gripping mechanism positioned near a top portion of the water storage reservoir.
