Solution Overview
Problem
Existing cleaning compositions are inadequate for effectively removing burnt-on food deposits from stovetop, oven, and grill surfaces at ambient temperature without using caustic or abrasive materials.
Innovation Solution
Non-caustic hard surface cleaning formulations comprising a carboxylic copolymer, nonionic alkoxylated surfactant, polyetheramine, organic solvent, and water, which are applied at ambient temperature to dissolve and wipe off burnt-on food deposits without the need for personal protective equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cleaning compositions are used to remove burnt-on food deposits, then cleaning capability is improved, but caustic or abrasive materials are required which pose safety hazards and require personal protective equipment
Solution Approach 1:
The patent changes the chemical parameters of the cleaning composition by using non-caustic organic solvents (glycol ethers, glycol esters, carboxylic acid esters) instead of conventional caustic materials. This parameter change maintains cleaning effectiveness while eliminating the need for personal protective equipment and reducing safety hazards.
Solution Approach 2:
The invention uses a composite solvent system combining multiple organic solvents (glycol ether, glycol ester, carboxylic acid ester) with surfactants and optional co-solvents. This composite material approach achieves synergistic cleaning effects that match or exceed caustic cleaners while maintaining user safety.
2Use of energy by moving object
If ambient temperature cleaning is used, then energy consumption and user comfort are improved, but removal effectiveness of burnt-on deposits deteriorates
Solution Approach 1:
The patent changes the chemical reactivity parameters of the cleaning agents by selecting organic solvents with high solubility parameters for burnt-on food residues. These solvents (glycol ethers, glycol esters, carboxylic acid esters) maintain high cleaning effectiveness at ambient temperatures without requiring thermal energy input.
Solution Approach 2:
The invention replaces thermal-mechanical cleaning (heat and abrasion) with chemical dissolution mechanisms. The organic solvent system chemically dissolves burnt-on deposits through solvation, eliminating the need for heat activation while maintaining removal effectiveness.
3Object-affected harmful factors
If non-caustic formulations are used, then user safety is improved, but cleaning effectiveness on burnt-on deposits may deteriorate
Solution Approach 1:
The patent creates a composite cleaning formulation combining multiple organic solvent components (glycol ether, glycol ester, carboxylic acid ester) with surfactants and optional co-solvents. This composite material provides synergistic effects that maintain high cleaning effectiveness while ensuring user safety through non-caustic ingredients.
Solution Approach 2:
The organic solvents act as intermediary substances that bridge the gap between safety and effectiveness. These solvents intermediate between the user (safe contact) and the burnt-on deposits (effective removal), enabling cleaning action without caustic harm.
4Reliability
If abrasive materials are used for cleaning, then removal power is improved, but surface damage and residue formation worsen
Solution Approach 1:
The patent replaces mechanical abrasion with chemical dissolution. The organic solvent system (glycol ethers, glycol esters, carboxylic acid esters) dissolves burnt-on deposits through chemical solvation rather than mechanical scraping, eliminating surface damage and abrasive residue while maintaining removal power.
