Solution Overview

Problem

Conventional grill and oven cleaning products often rely on harsh caustic liquids that are difficult to transport, store, and use safely, posing health and environmental hazards, and require strenuous scrubbing to remove hardened food residues, while also being bulky and inefficient.

Innovation Solution

A non-caustic solid powder cleaner composition is developed, comprising sodium chloride, chelators like sodium metasilicate, surfactants such as sodium lauryl sulfate and ethoxylated alcohol, and thickening agents like hydroxyethylcellulose, which, when mixed with water, forms a cleaning solution effective for removing residues without the need for caustic chemicals and with improved flowability and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional caustic liquid cleaners are used, then cleaning effectiveness on hardened residues is improved, but safety hazards and environmental harm increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidsafety hazards and environmental harm
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical parameters of the cleaner by replacing caustic bases (sodium hydroxide) with non-caustic alternatives (sodium carbonate, sodium bicarbonate, calcium carbonate). This parameter substitution maintains cleaning effectiveness through carbonate-based chemistry while eliminating the harmful caustic properties that cause safety hazards and environmental damage.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite powder formulation combining multiple ingredients including carbonate bases, chelating agents (EDTA, citric acid), surfactants, and oxidizing agents. This composite approach integrates multiple cleaning mechanisms into a single non-caustic system that effectively removes hardened residues without the harmful effects of traditional caustic cleaners.

Inventive Principle:
Principle #40Composite materials

2Productivity

If caustic liquid cleaners are used, then cleaning power is improved, but ease of transport and storage deteriorates due to bulk and weight

Engineering Contradiction:
Improvecleaning powerVSAvoidtransport and storage convenience
Core Design Contradiction:
ProductivityVSWeight of moving object

Solution Approach 1:

The patent transitions the cleaner from liquid phase to solid powder phase. This phase change dramatically reduces weight and bulk for transport and storage while maintaining cleaning power through the chemical composition of the powder. The powder form is compact, stable, and easier to handle while delivering the same cleaning effectiveness when dissolved in water.

Inventive Principle:
Principle #36Phase transitions

Solution Approach 2:

The patent changes the physical state parameter from liquid to solid powder, which fundamentally alters the density and volume characteristics. This parameter change enables concentrated cleaning agents to be stored and transported in compact forms without the bulk and weight issues of liquid cleaners, while the chemical composition ensures cleaning power is maintained.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If conventional liquid cleaners are used, then residue removal capability is improved, but ease of operation deteriorates due to required strenuous scrubbing

Engineering Contradiction:
Improveresidue removal capabilityVSAvoidscrubbing effort required
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent formulates a composite powder containing carbonate bases for chemical action, chelating agents to bind to residue components, surfactants to emulsify and lift residues, and oxidizing agents to break down organic matter. This multi-component system works synergistically to remove residues more easily than conventional cleaners, reducing the need for strenuous scrubbing while maintaining or improving removal capability.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent modifies the chemical parameters of the cleaning system by introducing chelating agents and oxidizing agents in addition to carbonate bases. These parameter changes create a more effective chemical environment that softens and breaks down hardened residues, making them easier to remove with less mechanical scrubbing effort while maintaining high residue removal capability.

Inventive Principle:
Principle #35Parameter changes
