Solution Overview

Problem

Automatic dishwashing detergents face challenges in effectively removing burnt-on baked-on soils from dishware, particularly stainless steel surfaces, due to their difficulty in adhering to and breaking down these tough soils during the washing process.

Innovation Solution

A dishwashing detergent composition incorporating xylanase and a sulphonated carboxylate polymer, which enhances enzymatic activity against azo-arabinoxylan substrates and utilizes a sulphonated acrylic polymer to improve soil removal efficacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional detergents are used to remove burnt-on baked-on soils, then general cleaning is achieved, but effective removal of tough burnt-on soils from stainless steel surfaces is not achieved

Engineering Contradiction:

Improvesoil removal effectivenessVSAvoiddifficulty in removing burnt-on soils

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical parameters of the detergent by incorporating xylanase enzyme (which breaks down polysaccharides in burnt-on soils) and sulphonated carboxylate polymer (which enhances soil suspension and removal). This biochemical parameter change enables effective degradation of burnt-on soils that conventional physical cleaning methods cannot remove.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite detergent system combining multiple components: xylanase enzyme, sulphonated carboxylate polymer, and other detergent additives. This composite formulation synergistically addresses the complexity of burnt-on soil removal by integrating enzymatic breakdown with polymer-based suspension and removal mechanisms.

Inventive Principle:

Principle #40Composite materials

2Ease of manufacture

If the detergent formulation is simplified, then manufacturing is easier, but the ability to address multiple soil types and surfaces is reduced

Engineering Contradiction:

Improvedetergent formulation simplicityVSAvoidsoil and surface coverage

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent designs a universal detergent formulation that simultaneously addresses multiple soil types (burnt-on, baked-on, food residues) and surface types (stainless steel, glass, ceramic) through the combined action of xylanase enzyme and sulphonated carboxylate polymer. This multi-functional approach eliminates the need for separate specialized detergents for different cleaning challenges.

Inventive Principle:

Principle #6Universality (Multi-functionality)
