Atomizer Humidity Control Using Refrigerator Operational Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerators typically have dry interior compartments, which can lead to food freshness issues, and existing systems that add moisture are often energy-intensive or ineffective in maintaining optimal humidity levels.
Innovation Solution
A control system and method that determines the humidity level in a refrigerator's compartment and uses an atomizer to adjust it based on temperature, defrost timer, and door opening times, incorporating a modular atomization unit with a water tank, water delivery assembly, and docking station to disperse moisture effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If moisture is added to the refrigeration compartment to maintain food freshness, then humidity level is improved, but energy consumption increases
Solution Approach 1:
The system uses the refrigerator's existing operational parameters (compressor timing, defrost cycles, door opening patterns) to intelligently control humidification, allowing the system to serve itself by leveraging already-present operational data rather than requiring separate sensing and control systems
Solution Approach 2:
The control system dynamically adjusts humidification based on changing operational parameters such as compressor run time, defrost timing, and door opening frequency, modifying the humidification parameter in response to other system parameters to optimize both humidity maintenance and energy efficiency
2Reliability
If an atomizer system is installed to control humidity, then humidity control capability is improved, but device complexity increases
Solution Approach 1:
The atomizer assembly is designed to perform multiple functions: humidification, water storage, and integration with the refrigerator's existing electrical system. The modular design allows it to serve as a complete humidification subsystem that interfaces with general refrigerator operations rather than requiring specialized dedicated components
Solution Approach 2:
The humidification system is divided into modular components including a removable water tank, atomizer assembly, and docking station, allowing independent installation, maintenance, and replacement of individual components without affecting the entire refrigerator system

AI summary
A method and system is provided which receives a desired humidity level from a user for the refrigeration compartment of a refrigerator, determines the current humidity level, and then activates an atomizer in the refrigeration compartment to increase the humidity level if needed. The humidity in the refrigeration compartment may be determined based at least in part on the temperature of the refrigeration compartment, the defrost timer, the door opening times, and the compressor timer.
