Solution Overview

Problem

Current desalination technologies are energy-intensive and costly, failing to efficiently meet the increasing global demand for freshwater due to their inefficiencies in energy usage and cost-effectiveness.

Innovation Solution

A vacuum-applied multi-phase system that utilizes the natural processes of evaporation and freezing to purify water, leveraging the inherent heat transfer properties across different phases of water to drive the desalination process, incorporating a system with primary and secondary vessels and a vacuum apparatus to evaporate and freeze water portions, separating contaminants and producing purified water.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If conventional desalination technologies are used, then water purification is achieved, but energy consumption is high and cost is high

Engineering Contradiction:
Improveenergy consumptionVSAvoidwater purification effectiveness
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent utilizes phase transitions of water (liquid to vapor during evaporation, vapor to liquid during condensation, liquid to solid during freezing) to achieve desalination. The vacuum environment lowers the boiling point, enabling evaporation at lower temperatures and reducing energy consumption while maintaining effective separation of salt and water through phase changes.

Inventive Principle:
Principle #36Phase transitions

Solution Approach 2:

The patent changes the pressure parameter by creating a vacuum environment, which fundamentally alters the phase transition temperatures of water. This parameter change allows evaporation to occur at temperatures below 100°C, significantly reducing the energy input required compared to conventional high-temperature distillation methods while maintaining effective desalination.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If evaporation and freezing methods are used, then energy requirements are reduced, but the rate of freshwater production must be increased

Engineering Contradiction:
Improvefreshwater production rateVSAvoidenergy requirements
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent divides the water body into multiple portions that undergo different phase transitions simultaneously - some water evaporates while other portions freeze. This segmentation allows parallel processing of multiple water portions, increasing the overall freshwater production rate without proportionally increasing energy consumption, as the freezing process releases latent heat that can be utilized.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent establishes a continuous cycle where evaporated water is condensed and collected, while frozen water is melted and collected, with both processes occurring continuously rather than batch-wise. The vacuum apparatus maintains continuous operation, and the system design allows for continuous feed and product removal, maximizing productivity while maintaining low energy requirements through the sustained phase transition processes.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A system and method of distilling/desalinating water in a vacuum-applied multi-phase manner purifies water of its dissolved and/or undissolved contaminants. The system includes at least one primary vessel (1), at least one vacuum apparatus (2), and at least one secondary vessel (3). The primary vessel (1) initially retains a quantity of source water. A vacuum pressure is then generated inside the primary vessel (1) with the vacuum apparatus (2), which evaporates a first water portion off the source water and freezes a second water portion on the source water. The first water portion is then condensed inside the secondary vessel (3). After the remaining source water is drained out of the primary vessel (1), the first water portion in its liquid state is transferred into the primary vessel (1) and poured onto the second water portion in its solid state, which melts the first water portion and the second water portion together to be a quantity of purified water.
