Solution Overview

Problem

Current antacid medications for hyperacidity and associated stomach issues often cause side effects such as constipation, aluminum intoxication, hypercalcaemia, and metabolic alkalosis, and do not provide long-term protection to the affected tissue.

Innovation Solution

A pharmaceutical composition combining magnesium trisilicate as a gastric acid-binding agent with alginic acid or its salts and optionally vegetable or essential oils, forming a viscous foam barrier that reduces gastroesophageal reflux and neutralizes excess gastric acid without systemic side effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If traditional antacids (aluminum hydroxide, magnesium hydroxide, calcium carbonate) are used to neutralize gastric acid, then acid neutralization is achieved, but side effects such as constipation, aluminum intoxication, hypercalcaemia, and metabolic alkalosis occur

Engineering Contradiction:
Improvegastric acid aggressionVSAvoidside effects (constipation, aluminum intoxication, hypercalcaemia, metabolic alkalosis)
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent extracts and eliminates the harmful components (aluminum, excessive magnesium, calcium) from traditional antacid formulations, retaining only magnesium trisilicate in controlled amounts combined with alginic acid, thereby removing the sources of aluminum intoxication, hypercalcaemia, and severe constipation while maintaining acid-neutralizing capability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a composite material system combining magnesium trisilicate (antacid component) with alginic acid (mucus-forming component) in specific ratios, where the two materials work synergistically to provide acid neutralization without the harmful side effects of traditional single-component antacids

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If aluminum-containing antacids are used to neutralize stomach acid, then acid neutralization is effective, but constipation and aluminum intoxication occur

Engineering Contradiction:
Improvegastric acidVSAvoidconstipation and aluminum intoxication
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent completely removes aluminum from the formulation, eliminating the source of aluminum intoxication and constipation associated with aluminum-containing antacids, while maintaining effective acid neutralization through magnesium trisilicate

Inventive Principle:
Principle #2Taking out (Extraction)

3Object-affected harmful factors

If calcium-based antacids are used to neutralize gastric acid, then acid neutralization is achieved, but hypercalcaemia, alkalosis, and kidney failure risk increase

Engineering Contradiction:
Improvegastric acidVSAvoidhypercalcaemia, alkalosis, kidney failure
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent removes calcium from the antacid formulation, eliminating the risk of hypercalcaemia, metabolic alkalosis, and milk-alkaline syndrome associated with calcium-based antacids, while maintaining therapeutic effectiveness through magnesium trisilicate

Inventive Principle:
Principle #2Taking out (Extraction)

4Object-affected harmful factors

If sodium bicarbonate is used to neutralize stomach acid, then rapid acid neutralization occurs, but metabolic alkalosis, high sodium load, and gastric rupture risk occur

Engineering Contradiction:
Improvegastric acidVSAvoidmetabolic alkalosis, sodium load, gastric rupture
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent eliminates sodium bicarbonate from the formulation, removing the sources of metabolic alkalosis, excessive sodium load, and gastric rupture risk, while maintaining effective acid neutralization through the slower-acting but safer magnesium trisilicate

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the reaction kinetics parameter by using magnesium trisilicate instead of rapid-acting sodium bicarbonate, achieving a slower, more controlled acid neutralization that prevents gastric rupture while avoiding metabolic alkalosis through the absence of sodium and bicarbonate

Inventive Principle:
Principle #35Parameter changes

5Object-affected harmful factors

If proton pump blockers or H2 receptor antagonists are used to treat severe hyperacidity, then acid production is reduced, but serious side effects including headache, diarrhea, myopathies, and hepatitis occur

Engineering Contradiction:
Improvegastric acid productionVSAvoidserious side effects (headache, diarrhea, myopathies, hepatitis)
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent uses locally acting, short-duration antacid materials (magnesium trisilicate and alginic acid) that neutralize acid at the site of action without systemic absorption, avoiding the serious systemic side effects of proton pump blockers and H2 receptor antagonists while providing sufficient symptom relief

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