Solution Overview

Problem

Existing water re-circulating systems in commercial and industrial settings face challenges in effectively treating water to inhibit corrosion, scaling, and odor, as conventional chemical treatments may not uniformly distribute and dissolve in recirculating water.

Innovation Solution

A water treatment feeder device comprising a hopper and receptacle with a porous lower V-shaped portion and a weir, which allows water treatment granules to dissolve in a time-release manner, ensuring uniform infusion of chemicals into the water stream, thereby treating the water effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional chemical treatments are used in water re-circulating systems, then water treatment is provided, but uniform distribution and dissolution of chemicals is not achieved

Engineering Contradiction:
Improvewater treatment effectivenessVSAvoidchemical distribution uniformity
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The hopper includes a lower V-shaped hopper portion fabricated from a porous material having a plurality of pores. These pores are sized to at least substantially retain the water treatment granules in the lower V-shaped hopper portion while allowing water to pass through, enabling uniform dissolution and distribution of chemicals in the recirculating water system.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The hopper is divided into an upper box-shaped hopper portion and a lower V-shaped hopper portion. The upper portion receives and stores granules, while the lower V-shaped portion with its porous structure facilitates controlled release and uniform distribution. This segmentation allows different functions to be performed in different regions, improving overall treatment effectiveness.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If water treatment granules are introduced into recirculating water, then corrosion and scaling are inhibited, but granule dissolution is not uniform

Engineering Contradiction:
Improvecorrosion and scaling inhibitionVSAvoidgranule dissolution uniformity
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The lower V-shaped hopper portion is fabricated from a porous material with pores sized to retain granules while allowing water flow. This porous structure enables water to percolate through the granules uniformly, ensuring consistent dissolution and preventing localized concentration gradients that would cause non-uniform treatment effectiveness.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The system changes the physical state and distribution parameters of the granules by introducing them into a porous structure with controlled water flow. This modifies the dissolution kinetics and ensures uniform distribution of active chemicals throughout the recirculating water system, improving treatment reliability.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If a hopper with porous lower V-shaped portion is used, then uniform chemical distribution is achieved, but device structure becomes more complex

Engineering Contradiction:
Improvechemical distribution uniformityVSAvoidhopper structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The lower V-shaped hopper portion uses a porous material that provides uniform distribution functionality. While the porous structure adds some complexity, it eliminates the need for additional distribution components such as pumps, pipes, or diffusers, thereby simplifying the overall device architecture while achieving uniform chemical distribution.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The hopper combines multiple functions into a single integrated structure: granule storage (upper box-shaped portion), granule retention (porous lower V-shaped portion), and uniform distribution (water flow through porous material). This merging eliminates the need for separate components and reduces overall device complexity despite the sophisticated porous structure.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A water treatment feed device includes a hopper and a receptacle. The hopper has a granule-receiving compartment defined by an upper hopper portion and a lower V-shaped hopper portion connected to the upper hopper portion. The lower V-shaped hopper portion is fabricated from a porous material having a plurality of pores sized to at least substantially retain conventional water treatment granules therein. The receptacle has a water-receiving compartment with a weir disposed therein to divide the water-receiving compartment into a water inlet sub-compartment and a water outlet sub-compartment with the water inlet sub-compartment sized to receive the hopper loaded with conventional water treatment granules. A water treatment feed system and a method for dissolving conventional water treatment granules in water are also described.
