Solid Degreasing Composition for Baked-On Grease Without Residue

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need for solid cleaning compositions that provide equivalent cleaning efficacy to liquid products, are high alkaline, environmentally friendly, and do not leave residues or films, particularly for removing baked-on greasy soils.

Innovation Solution

The compositions consist of at least two alkali metal alkalinity sources, a chelant, and a surfactant, which are formulated as solid tablets or blocks, avoiding phosphates and NTA, and maintaining dimensional stability to ensure effective cleaning and degreasing without residue formation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If liquid cleaning formulations are used, then cleaning efficacy is achieved, but manufacturing, transport and storage become difficult due to substantial water content

Engineering Contradiction:

Improvemanufacturing easeVSAvoidwater content

Core Design Contradiction:

Ease of manufactureVSQuantity of substance

Solution Approach 1:

The patent transforms the cleaning composition from liquid phase to solid phase by removing substantial water content. The solid formulation maintains cleaning efficacy while eliminating the handling and transport difficulties associated with liquid formulations containing high water content.

Inventive Principle:

Principle #36Phase transitions

Solution Approach 2:

The patent changes the physical state parameter from liquid to solid by concentrating the active cleaning components and removing water. This parameter change enables improved handling, enhanced safety, and elimination of component segregation during transportation and storage.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If solid cleaning compositions are formulated with high alkalinity, then cleaning efficacy for greasy soils is improved, but residue and film formation on surfaces may occur

Engineering Contradiction:

Improvecleaning efficacyVSAvoidresidue formation

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent carefully controls the pH parameter within the 10-13.5 range to optimize cleaning efficacy for baked-on greasy soils while preventing excessive alkalinity that would cause residue and film formation on cleaned surfaces.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses multiple alkalinity sources (sodium hydroxide, sodium carbonate, sodium metasilicate) that provide different local cleaning mechanisms, allowing effective soil removal while maintaining surface compatibility and minimizing residue.

Inventive Principle:

Principle #3Local quality

3Productivity

If phosphates are used in solid cleaning compositions, then soil suspension and hardness sequestration are improved, but ecological concerns arise

Engineering Contradiction:

Improvesoil removal efficiencyVSAvoidecological impact

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes phosphates and NTA from the cleaning composition formulation.替代 environmentally friendly chelants are used to maintain soil suspension and hardness sequestration functions without the ecological harm associated with phosphates.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent converts the ecological harm of phosphates into a benefit by using alternative chelating agents that provide the same cleaning functions (soil suspension, hardness sequestration) while being environmentally friendly and suitable for septic systems.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
