Solution Overview

Problem

Conventional dishwashing methods struggle with efficiently removing tough, burnt-on food soils without being harsh on hands or surfaces, and often require multiple products, especially with the increased use of microwave ovens for cooking.

Innovation Solution

A translucent cleaning composition is developed by combining a hydrogen bond receiving compound with a hydrogen bond providing compound to create a eutectic liquid, adding a perfume, and adjusting the pH above 6.0, which can include a surfactant to enhance cleaning efficiency and solubility of perfumes, resulting in a clear composition that effectively removes tough soils with reduced scrubbing and water usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional cleaners are used for tough food soil removal, then cleaning effectiveness is improved, but harshness on hands and surfaces increases

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidharshness on hands and surfaces

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical parameters of the cleaning composition by using a eutectic mixture of hydrogen bond donor and acceptor compounds instead of conventional harsh chemicals. This creates a effective cleaner that is gentler on skin and surfaces while maintaining cleaning power against tough food soils.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The invention uses a composite eutectic mixture combining hydrogen bond donor compounds (e.g., carboxylic acids) and acceptor compounds (e.g., quaternary ammonium salts) to create a synergistic cleaning system that achieves effective soil removal without the harshness of conventional single-component cleaners.

Inventive Principle:

Principle #40Composite materials

2Reliability

If multiple specialty products are used for complete cleaning, then cleaning effectiveness is improved, but convenience decreases

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidconvenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent creates a universal cleaning composition that can handle multiple types of food soils (grease, protein, carbohydrate) and various cooking methods (conventional and microwave) with a single product, eliminating the need for multiple specialty cleaners and improving consumer convenience.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges the functions of multiple specialty pre-treatment products into a single comprehensive cleaner by using a eutectic mixture that provides broad-spectrum cleaning effectiveness against all types of food soils, consolidating what would otherwise require separate products.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If prolonged soaking and heavy scouring are used for tough soil removal, then cleaning effectiveness is improved, but time and effort increase

Engineering Contradiction:

Improvecleaning effectivenessVSAvoidtime and effort

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces mechanical scouring actions with a chemically active eutectic mixture that actively breaks down and dissolves tough food soils through hydrogen bonding mechanisms, reducing or eliminating the need for heavy mechanical scrubbing and associated time loss.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
