Solution Overview
Problem
Existing humidifier systems fail to maintain a consistent boiling rate of fluid in reservoirs due to imprecise measurement of fluid levels, leading to unacceptable variations in humidity levels in environments.
Innovation Solution
A system that measures the fluid level of a turbulated base fluid by determining at least one first height above and one second height below a sensor, allowing for more accurate and precise determination of the fluid level, and introduces additional fluid in a graduated manner using a control valve to maintain the boiling rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If water level is measured using discrete point sensors or floating level sensors, then the measurement system is simple, but the measurement precision is insufficient leading to imprecise fluid level determination
Solution Approach 1:
The fluid level measurement is segmented into multiple discrete height measurements (first height above fluid level, second height below fluid level) taken by a sensor array. This segmentation allows precise determination of the fluid level by establishing it according to multiple measured heights rather than relying on a single discrete sensor point, directly resolving the measurement precision issue.
2Speed
If additional fluid is introduced rapidly when level sensors trigger, then the response time is fast, but the boiling rate diminishes due to sudden temperature decrease
Solution Approach 1:
The control valve operates dynamically by gradually opening to introduce input fluid at a controlled rate rather than fully opening rapidly. This dynamic control allows the system to respond quickly to fluid level changes while maintaining the boiling rate by preventing sudden temperature decreases that would occur with rapid fluid introduction.
Solution Approach 2:
The system uses continuous feedback from the sensor array measuring fluid level heights to control the valve opening. The controller monitors the established fluid level and adjusts the valve opening gradually to maintain the desired fluid level while preserving the boiling rate, creating a closed-loop control system that balances response speed with temperature stability.
3Reliability
If floating level sensors are used in turbulated fluid, then the device complexity is low, but the measurement reliability is poor due to inconsistent readings from moving fluid
Solution Approach 1:
Instead of relying on a single floating sensor that provides inconsistent readings in turbulated fluid, the system segments the measurement into multiple fixed sensor positions (sensor array) that measure heights above and below the fluid level. This segmentation provides multiple data points that can be processed to establish a reliable fluid level despite fluid turbulence, significantly improving measurement reliability.
Solution Approach 2:
The patent replaces the mechanical floating level sensor system with an electrical/electronic sensor array system that takes fixed positional measurements. This substitution eliminates the mechanical floating component that is susceptible to turbulence, providing more reliable and consistent fluid level measurements in turbulated conditions.

AI summary
A method for maintaining a boiling rate of a base fluid can include a determination of a fluid level of a turbulated base fluid in a reservoir. The fluid level can be determined by measuring at least one first height of the turbulated base fluid above the fluid level with at least a first sensor. The fluid level can be determined by measuring at least one second height of the turbulated base fluid below the fluid level with the first sensor. The method can include the establishment of the fluid level of the turbulated base fluid. The fluid level can be established according to the measured at least one first and second heights. The method can include the graduated introduction of an input fluid into the reservoir. A control valve can gradually introduce the input fluid in proportion to the established fluid level of the turbulated base fluid.
