Solution Overview

Problem

Existing dissolution chambers for tablets in cleaning and irrigation systems face inefficiencies due to high water or solvent consumption, incomplete dissolution of tablets, and deposition of abrasive components, leading to reduced cleaning effectiveness and cumbersome cleaning procedures.

Innovation Solution

A hydrodynamically shaped dissolution chamber with a centrifugal element creating a coerced vortex to keep the tablet horizontally afloat, ensuring uniform water circulation and preventing breakage, combined with a filtering mesh and spiral finger brackets to facilitate even erosion and complete dissolution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If the tablet size is reduced to decrease material carry-away, then the cleaning effect declines, but complete dissolution requires much water or solvent which is wasteful

Engineering Contradiction:

Improvematerial carry-awayVSAvoidwater or solvent consumption

Core Design Contradiction:

Loss of substanceVSQuantity of substance

Solution Approach 1:

The patent applies hydraulic principles by using a centrifugal element to create a coerced vortex flow pattern in the dissolution chamber. This vortex generates centrifugal forces that keep the tablet horizontally afloat and ensure uniform water circulation around it, enabling complete dissolution with reduced water consumption while maintaining cleaning effectiveness.

Inventive Principle:

Principle #29Pneumatics and hydraulics

Solution Approach 2:

The tablet is kept in a dynamic state by the coerced vortex, which continuously moves water around the tablet in a rotational pattern. This dynamic flow prevents stagnation and ensures all surfaces of the tablet are uniformly exposed to dissolving water, achieving complete dissolution efficiently.

Inventive Principle:

Principle #15Dynamics

2Productivity

If turbulent flow is used to enhance dissolution, then cleaning effect improves, but deposition occurs at walls and in corners

Engineering Contradiction:

Improvedissolution efficiencyVSAvoiddeposition at walls and corners

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The centrifugal element creates a controlled coerced vortex that generates centrifugal forces pushing the tablet toward the chamber walls, while the rotational flow pattern prevents deposition by continuously moving materials along the walls rather than allowing them to settle in corners or stagnant zones.

Inventive Principle:

Principle #29Pneumatics and hydraulics

Solution Approach 2:

The coerced vortex generates an upward centrifugal force that counteracts gravity, keeping the tablet horizontally afloat rather than allowing it to settle at the bottom where deposition would occur. This anti-gravity effect prevents harmful deposition while maintaining dissolution efficiency.

Inventive Principle:

Principle #8Anti-weight (Counterweight)

3Productivity

If abrasive components are used to improve cleaning effect, then cleaning effectiveness increases, but deposition in partitions with low flow rate occurs

Engineering Contradiction:

Improvecleaning effectivenessVSAvoiddeposition in partitions

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The coerced vortex flow pattern creates high-velocity rotational flow that carries abrasive components uniformly through the dissolution chamber, preventing them from settling in partitions or corners with low flow rate. The centrifugal forces keep the abrasive-laden water moving continuously along the chamber walls.

Inventive Principle:

Principle #29Pneumatics and hydraulics

4Productivity

If tight nozzles are used to achieve appropriate cleaning effect at high pressure, then cleaning effectiveness improves, but flow speed decreases

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidflow speed

Core Design Contradiction:

ProductivityVSSpeed

Solution Approach 1:

The coerced vortex creates a dynamic rotational flow pattern that maintains high flow speeds throughout the dissolution chamber. The centrifugal forces generated by the vortex keep the water and tablet in constant motion, ensuring high-velocity flow reaches the nozzle while maintaining cleaning effectiveness.

Inventive Principle:

Principle #15Dynamics
