Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing solutions fail to effectively address both blood ethanol concentration and acetaldehyde toxicity simultaneously during alcohol metabolism, particularly in the critical early phase when ethanol levels are high and acetaldehyde accumulates rapidly, leading to adverse health effects.

Innovation Solution

A pharmaceutical composition combining alcohol dehydrogenase (ADH) with acetaldehyde scavengers, such as thiol-containing compounds or agents that sequester acetaldehyde, to accelerate ethanol metabolism and neutralize resulting acetaldehyde, leveraging Le Chatelier's principle to maintain a low acetaldehyde concentration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If alcohol dehydrogenase activity is enhanced to accelerate ethanol clearance, then blood ethanol concentration is reduced more rapidly, but acetaldehyde concentration increases and exacerbates toxicity

Engineering Contradiction:

Improveethanol clearance rateVSAvoidacetaldehyde toxicity

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes the harmful acetaldehyde intermediate from the metabolic pathway by introducing external scavengers (aldehyde dehydrogenase, thiol compounds, or cyclodextrins) that specifically bind or metabolize acetaldehyde, separating the ethanol clearance function from the toxic acetaldehyde accumulation problem

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces intermediary substances (aldehyde dehydrogenase as an enzymatic mediator, or thiol/cyclodextrin compounds as chemical mediators) that facilitate the conversion or binding of acetaldehyde, enabling the system to handle the toxic intermediate without direct harm to the organism

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If acetaldehyde metabolism is impaired due to genetic polymorphisms in aldehyde dehydrogenase, then acetaldehyde accumulates and causes symptoms such as Asian flush, but enhancing ADH activity alone cannot resolve the accumulation problem

Engineering Contradiction:

Improveacetaldehyde metabolism efficiencyVSAvoidacetaldehyde accumulation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the metabolic parameters by introducing alternative enzymes or chemical scavengers that operate independently of the defective ALDH2*2 pathway, effectively bypassing the genetic limitation and restoring normal acetaldehyde clearance capacity

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces a functional copy or alternative pathway for acetaldehyde metabolism through recombinant aldehyde dehydrogenase or chemical scavengers, compensating for the defective endogenous ALDH2 enzyme in polymorphic individuals

Inventive Principle:

Principle #26Copying

3Adaptability or versatility

If no simultaneous solution for EtOH and AcH clearance is provided, then either ethanol or acetaldehyde levels remain elevated, but addressing only one parameter leaves the other unmanaged

Engineering Contradiction:

Improvecomprehensive alcohol metabolism managementVSAvoidunmanaged toxic byproduct

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent merges two previously separate therapeutic approaches (ADH enhancement and AcH scavenging) into a single combined composition or method, enabling simultaneous management of both ethanol clearance and acetaldehyde toxicity in one intervention

Inventive Principle:

Principle #5Merging (Combining)
