Solution Overview

Problem

Existing detergent packages for automatic dishwashing cycles face challenges in achieving superior wash performance while maintaining cost-effectiveness and minimizing environmental impact, often requiring increased quantities of non-biodegradable or toxic cleaning actives.

Innovation Solution

A package comprising a specific weight ratio of solid and gel detergent compositions, ranging from 1.60:1 to 3.00:1, optimized to enhance wash performance without significantly increasing active ingredients, and optionally including a liquid detergent in a multi-compartment format for tailored dissolution profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If increased quantities of cleaning actives are incorporated into the package, then cleaning performance is improved, but environmental impact and manufacturing costs increase

Engineering Contradiction:

Improvecleaning performanceVSAvoidenvironmental impact

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the physical state parameter of the detergent composition from conventional solid forms to gel form. This parameter change allows for improved cleaning performance through better dissolution and distribution of cleaning actives, while using optimized quantities that reduce environmental impact and costs

Inventive Principle:

Principle #35Parameter changes

2Reliability

If increased quantities of cleaning actives are incorporated into the package, then cleaning performance is improved, but manufacturing costs increase

Engineering Contradiction:

Improvecleaning performanceVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

3Reliability

If gel detergent composition is added to the package, then cleaning performance is improved, but the weight ratio optimization is required to avoid excessive gel content

Engineering Contradiction:

Improvecleaning performanceVSAvoidgel composition amount

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent optimizes the weight ratio parameter between solid and gel detergent compositions to achieve the balance between improved cleaning performance and controlled gel content, preventing excessive gel from causing handling or dissolution issues

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite detergent package containing both solid and gel detergent compositions in specific weight ratios. This composite approach combines the advantages of both forms - the stability and ease of handling of solids with the superior dissolution and cleaning performance of gels

Inventive Principle:

Principle #40Composite materials
