Existing methods for cleaning industrial equipment surfaces are limited by their non-universality, requirement for hot solutions, instability, and high toxicity, particularly failing to efficiently remove metal oxides and being costly for waste management.

Innovation Solution

A cleaning solution comprising hydrogen peroxide, a complexing agent, calixarene, and water, with optional organic acids, peroxide decomposition stabilizers, surfactants, and inhibitors, which combines mechanical, chemical, and physico-chemical actions to effectively remove deposits without heating, utilizing the exothermic effect of peroxide decomposition for intense gas formation and loosening deposits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If hot solutions are used for cleaning, then the cleaning effectiveness is improved, but the toxicity and aggressiveness of the solution increases

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidtoxicity and aggressiveness
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the temperature parameter from hot (heated state) to cold (ambient temperature), fundamentally altering the cleaning mechanism from thermal activation to chemical activation through peroxide decomposition. This resolves the contradiction by maintaining cleaning effectiveness through chemical action while eliminating the need for heating, thus reducing toxicity and aggressiveness.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the thermal field (heating) with a chemical field (peroxide decomposition). Instead of using heat to activate cleaning agents, the system uses chemically active peroxide that decomposes at ambient temperatures to produce oxygen and heat locally only where needed, substituting the mechanical/thermal system with a chemical system that achieves the same cleaning effect without global heating.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If peroxides are used for cleaning, then the removal of deposits is improved, but the instability of oxidation capacity increases

Engineering Contradiction:
Improveremoval of depositsVSAvoidoxidation capacity stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The patent introduces calixarene as an intermediary substance that mediates between hydrogen peroxide and the deposits. Calixarene forms inclusion complexes with metal ions in the deposits, facilitating controlled peroxide decomposition and maintaining stable oxidation capacity. This intermediary prevents premature decomposition and ensures consistent cleaning performance throughout the treatment process.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite cleaning system combining hydrogen peroxide, calixarene, and complexing agents. This composite formulation synergistically enhances the stability and effectiveness of peroxide oxidation, with calixarene and complexing agents working together to control the decomposition rate and maintain active oxygen availability throughout the cleaning process.

Inventive Principle:
Principle #40Composite materials

3Productivity

If heating is applied to the sample, then the cleaning efficiency is improved, but the energy consumption increases

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent enables the cleaning system to be self-heating through the exothermic decomposition of hydrogen peroxide. The decomposition reaction itself generates the heat needed to activate the cleaning action, eliminating the need for external heating energy input. The system uses its own chemical energy to drive the cleaning process, achieving self-service functionality.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent utilizes the phase transition and decomposition of hydrogen peroxide (liquid to gas oxygen) as the energy source. The decomposition process releases energy that locally heats the cleaning solution at the point of application, providing the thermal activation needed for effective cleaning without requiring external heating systems.

Inventive Principle:
Principle #36Phase transitions

4Productivity

If conventional cleaning solutions are used, then the removal of certain deposits is achieved, but the universality is limited

Engineering Contradiction:
Improvedeposit removal capabilityVSAvoidapplicability to different surfaces
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal cleaning solution formulated with hydrogen peroxide, calixarene, and broad-spectrum complexing agents that can effectively remove various types of deposits (metal oxides, carbonates, salts, organic matter) from different surfaces (metal, glass, ceramic). The formulation is designed to be multi-functional, adapting to different substrate types and deposit compositions through the synergistic action of its components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent adjusts the chemical parameters of the cleaning solution, specifically using hydrogen peroxide as the active oxidant and calixarene as the binding agent, creating a formulation that can adapt to different deposit types. The parameter optimization enables effective cleaning across multiple surface types without requiring separate formulations for different applications.

Inventive Principle:
Principle #35Parameter changes
