Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hard surface cleaning compositions are ineffective in removing burnt-on deposits from stovetop and oven surfaces at room temperature, particularly on glass, metal, and enameled metal surfaces.
Innovation Solution
A caustic cleaning composition comprising a binary system of benzyl alcohol and dipropylene glycol n-propyl ether, with optional pH adjusters like monoethanolamine and sodium hydroxide, and thickeners like smectite clay, effectively removes burnt-on deposits at room temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional non-caustic cleaning compositions are used, then safety is improved, but cleaning effectiveness on burnt-on deposits deteriorates
Solution Approach 1:
The patent changes the chemical parameters of the cleaning composition by incorporating caustic agents (sodium hydroxide, potassium hydroxide, or ammonium hydroxide) at controlled concentrations (0.1-10%, preferably 0.5-5%). This parameter change enables the composition to effectively remove burnt-on deposits while maintaining safety through controlled formulation and optional corrosion inhibitors.
Solution Approach 2:
The patent creates a composite cleaning composition that combines multiple functional components: caustic agents for stain removal, organic solvents (dipropylene glycol n-propyl ether and benzyl alcohol) for grease dissolution, surfactants for emulsification, and corrosion inhibitors for safety. This composite approach achieves both cleaning effectiveness and safety simultaneously.
2Reliability
If caustic cleaning compositions are used, then cleaning effectiveness is improved, but safety deteriorates
Solution Approach 1:
The patent controls the concentration of caustic agents within specific ranges (0.1-10%, preferably 0.5-5%) to balance cleaning effectiveness with safety. Lower concentrations maintain safety while higher concentrations within this range enhance cleaning power, allowing optimization based on specific application needs.
Solution Approach 2:
The patent introduces corrosion inhibitors as intermediary substances that mediate between the caustic cleaning agents and the surface being cleaned. These inhibitors form protective layers that prevent direct harmful interaction between the caustic agents and metal surfaces, thereby maintaining safety while preserving cleaning effectiveness.
3Reliability
If high temperature cleaning is used, then cleaning effectiveness is improved, but energy consumption increases
Solution Approach 1:
The patent changes the chemical reactivity parameters of the cleaning composition by using caustic agents that can effectively break down burnt-on deposits at room temperature or with minimal heating. This eliminates the need for high-temperature cleaning processes while maintaining cleaning effectiveness.
Solution Approach 2:
The patent replaces thermal energy input (heating) with chemical energy input (caustic agents). Instead of relying on heat to facilitate cleaning, the composition uses chemically active caustic substances that can dissolve and remove burnt-on deposits through chemical reactions, thereby reducing energy consumption.
4Productivity
If short contact time cleaning is used, then productivity is improved, but cleaning effectiveness deteriorates
Solution Approach 1:
The patent enhances the reactivity parameters of the cleaning composition by using highly active caustic agents that can rapidly break down burnt-on deposits. This increased chemical reactivity enables effective cleaning within shorter contact times, thereby improving productivity without sacrificing cleaning effectiveness.
Solution Approach 2:
The patent incorporates organic solvents (dipropylene glycol n-propyl ether and benzyl alcohol) that perform preliminary action by penetrating and softening grease-based burnt-on deposits before the caustic agents act on them. This preliminary softening reduces the time needed for complete removal, improving overall cleaning speed while maintaining effectiveness.
