Solution Overview

Problem

Existing solution-forming devices require frequent product replacement and costly modifications to prevent unwanted solution formation and backflow, especially in potable water systems, adding complexity and cost.

Innovation Solution

A freestanding solid product dispenser with a fluid inlet, reaction portion, and outlet, featuring a product guide, pegs for supporting the product, and a hull for even fluid flow, which controls fluid contact and dissolution, preventing backflow and ensuring consistent solution concentration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a freestanding dispenser design is used, then ease of operation and ease of manufacture are improved, but device complexity increases compared to in-line systems

Engineering Contradiction:
Improveease of useVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The dispenser is divided into distinct functional segments: an inlet portion for fluid entry, a reaction portion for solution formation, and an outlet portion for dispensing. This segmentation allows each portion to be optimized independently while maintaining overall simplicity of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dispenser design allows the solid product to automatically dissolve in the fluid as it flows through the reaction portion, eliminating the need for manual mixing or complex control mechanisms. The system self-regulates the solution formation process.

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If backflow prevention devices are added to potable water systems, then safety is improved, but device complexity and cost increase

Engineering Contradiction:
Improvehazardous backflow preventionVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The harmful backflow effect is extracted and contained within the sealed reaction portion of the dispenser. The design inherently prevents backflow into the potable water supply by directing fluid flow unidirectionally through the dissolution chamber, eliminating the need for additional backflow prevention devices.

Inventive Principle:
Principle #2Taking out (Extraction)

3Manufacturing precision

If in-line systems are used with continuous fluid flow, then solution formation is consistent, but unwanted solution formation occurs when not needed

Engineering Contradiction:
Improvesolution concentration consistencyVSAvoidunwanted solution formation control
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The dispenser design allows the solid product to be easily removed from the reaction portion when solution formation is not desired. The dynamic configuration enables quick product removal without requiring system shutdown or complex routing changes, preventing unwanted solution formation while maintaining consistency when in use.

Inventive Principle:
Principle #15Dynamics

AI summary

A method and apparatus for dispensing a solution of a solid product in a fluid. A freestanding apparatus comprises an inlet portion through which fluid enters, a reaction portion in which the fluid encounters and dissolves the product to form a solution, and an outlet portion from which the solution exits the apparatus. Fluid may encounter product from a single direction or multiple directions. The apparatus may be configured to receive a particularly shaped solid product, and may comprise a lid or gate to prevent fluid from contacting the product undesirably.
