Solution Overview
Problem
Atmospheric water generators face challenges such as high energetic costs, noise levels, size, and matching production with consumption demand, making them less competitive with traditional water dispensers.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the blower is positioned at the air outlet or in proximity thereto, then noise levels are reduced, but the apparatus size may be affected
Solution Approach 1:
The blower is nested within the enclosure structure, positioned at the air outlet or in proximity thereto, allowing the noisy component to be contained within the device footprint rather than extending outward. This nesting approach reduces noise propagation while minimizing the overall apparatus volume.
Solution Approach 2:
The blower positioning utilizes three-dimensional spatial arrangement within the enclosure, moving the noise source to a specific location (air outlet area) where it can be contained and directed, rather than placing it in a conventional location. This dimensional optimization reduces both noise and size.
2Manufacturing precision
If the evaporator assembly is configured with specific air inlet and outlet pathways, then airflow uniformity is enhanced, but device complexity increases
Solution Approach 1:
The evaporator assembly is divided into distinct functional zones with dedicated air inlet and outlet pathways, allowing controlled airflow patterns. This segmentation enables precise airflow management and uniform distribution across the evaporator surface without requiring complex external control systems.
Solution Approach 2:
The evaporator assembly design allows the airflow to self-regulate and distribute uniformly through the structured inlet and outlet pathways, eliminating the need for additional active control mechanisms. The geometry itself performs the airflow distribution function.
3Productivity
If the condenser is positioned downstream of the blower, then water production efficiency is improved, but energy consumption increases
Solution Approach 1:
Positioning the condenser downstream of the blower maintains continuous airflow through the system, ensuring that the cooling action on water vapor occurs in the same air stream that is being moved through the evaporator. This continuous action improves water production efficiency without requiring additional energy input for separate condensation processes.

This configuration effectively reduces noise levels, minimizes the apparatus' size, and enhances the uniformity of airflow, leading to more efficient water production and better alignment with consumption demands.
Implementation Method 1
extraction of water from air by atmospheric water generators, is well known and typically involves enforcement of condensation conditions of air containing water vapor (i.e. humid air) by lowering its temperature below the dew point temperature, thereby causing some vapor to condensate and liquid water is then released from the carrying air
Implementation Method 2
The blower is located at the air outlet or in proximity thereto... The blower and the condenser are located downstream the evaporator assembly
Implementation Method 3
a water generation refrigeration cycle comprising an evaporator and a porous barrier positioned parallel and proximal to air entries of the evaporator
