Solution Overview

Problem

Conventional methods for preparing red clay processed materials and alkali ionized water require high temperatures and long times, leading to high production costs and limitations in anti-corrosive and virus disinfecting activities due to the toxicity of synthetic antiseptics and instability of organic natural antiseptics.

Innovation Solution

A method involving mixing sodium hydroxide with red clay, heating the mixture at 1100 to 1300°C for 1 to 4 hours to create a liquid melt, cooling, and then pulverizing to produce a red clay processed material and alkali ionized water with anti-corrosive and virus disinfecting properties, reducing production costs and toxicity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional high temperature processing (1400-1700°C) is used to prepare red clay processed material, then the material achieves anti-corrosive and virus disinfecting activity, but production costs increase significantly

Engineering Contradiction:
Improveanti-corrosive and virus disinfecting activityVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies parameter changes by reducing the processing temperature from the conventional 1400-1700°C range to 1100-1300°C, and shortening the processing time from conventional long duration to 1-4 hours. This modification of thermal parameters achieves the required anti-corrosive and virus disinfecting activity while significantly reducing energy consumption and production costs.

Inventive Principle:

Solution Approach 2:

The patent uses composite materials by combining red clay with specific additives including sodium hydroxide, sodium carbonate, borax, and boric acid. This composite formulation enables the red clay to achieve the necessary reactivity and functional properties at lower temperatures (1100-1300°C) compared to pure red clay processing, thereby reducing production costs while maintaining reliability.

Inventive Principle:

Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies parameter changes by optimizing both temperature and time parameters simultaneously. The processing temperature is reduced to 1100-1300°C while the processing time is shortened to 1-4 hours. This parameter optimization achieves the required material activity without the need for conventional long duration processing, thereby reducing production time and associated costs.

Inventive Principle:

Solution Approach 2:

The composite material formulation with sodium hydroxide, sodium carbonate, borax, and boric acid enhances the reactivity of red clay, enabling sufficient virus disinfecting and anti-corrosive activity to be achieved within 1-4 hours at 1100-1300°C, rather than requiring conventional long duration processing.

If synthetic antiseptics are used for virus disinfecting, then disinfecting activity is achieved, but toxicity limits their use and application

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies this principle by using inorganic natural substances (red clay-based processed material) that can be applied and then discarded or neutralized without leaving toxic residues. The material provides effective virus disinfecting activity through physical and chemical mechanisms (adsorption, ion exchange) rather than through toxic synthetic antiseptic action, eliminating the toxicity limitation while maintaining disinfecting reliability.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent transforms the chemical state of red clay through controlled thermal processing at 1100-1300°C with specific additives, converting it into a processed material with enhanced virus disinfecting properties. This parameter change creates a material that achieves disinfecting activity through inorganic mechanisms (adsorption, ion exchange) rather than toxic chemical action, resolving the toxicity issue while maintaining effectiveness.

Inventive Principle:
Principle #35Parameter changes

4Stability of the object's composition

If organic natural antiseptics are used, then natural origin is achieved, but they decompose easily under various conditions reducing their stability

Engineering Contradiction:

Solution Approach 1:

The patent uses inorganic natural substances (red clay-based processed material) that are stable under various conditions including temperature changes, UV exposure, and biological resistance. The material provides virus disinfecting activity through physical mechanisms (adsorption, ion exchange) rather than through organic chemical compounds that decompose easily, thereby achieving both natural origin and stability without compromising disinfecting reliability.

Solution Approach 2:

The composite formulation combines red clay with inorganic additives (sodium hydroxide, sodium carbonate, borax, boric acid) that are stable under various environmental conditions. This inorganic composite material achieves virus disinfecting activity through stable physical and chemical mechanisms, overcoming the decomposition problem of organic natural antiseptics while maintaining natural origin and reliability.
