Solution Overview

Problem

Existing neutralization/water separation devices face inefficiencies in both neutralization reactions and water separation processes, often requiring external energy for one process to occur well, which contradicts the optimal conditions for the other, leading to compromised efficiency and increased complexity.

Innovation Solution

A neutralization/water separation device with separate tanks for neutralization and water separation, where the neutralization tank is positioned above the water separation tank, allowing gravity-driven transfer of the neutralized mixture without the need for a separate transfer pump, and incorporating a propeller stirrer and inclined bottom surface for efficient separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a combined neutralization/water separation tank is used, then the device structure is simplified, but both neutralization reactions and water separation cannot occur efficiently simultaneously

Engineering Contradiction:
Improvedevice structureVSAvoidprocess efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The device is segmented into two separate tanks: a upper neutralization tank and a lower water separation tank. Each tank is optimized for its specific function, allowing both neutralization reactions and water separation to occur efficiently without mutual interference, while still maintaining a relatively simple overall structure through vertical integration and gravity-driven connection.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If the neutralization tank is positioned above the water separation tank, then gravity-driven transfer eliminates the need for a transfer pump, but the structure becomes more complex with multiple tanks

Engineering Contradiction:
ImprovestructureVSAvoidoperation simplicity
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The neutralization tank is positioned at a higher elevation than the water separation tank, creating a gravitational potential difference. This allows the neutralized mixture to flow automatically from the upper tank to the lower tank without requiring external pumping, simplifying operation while the vertical arrangement keeps the overall structure compact.

Inventive Principle:
Principle #12Equipotentiality

3Volume of stationary object

If a transfer pump is used to move the neutralized mixture, then the transfer can be controlled, but the overall device volume increases and installation space is required

Engineering Contradiction:
Improvedevice volumeVSAvoidinstallation ease
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The transfer pump is completely removed from the system. Instead, a transfer line connects the upper neutralization tank to the lower water separation tank, utilizing gravity for automatic flow. This extraction of the pump component significantly reduces device volume and simplifies installation, especially in narrow spaces.

Inventive Principle:
Principle #2Taking out (Extraction)
