Solution Overview

Problem

Current methods for regulating blood pressure in hypertension patients using chemical synthesized drugs often come with side effects, and there is a need for more materials that can enhance the angiotensin converting enzyme (ACE) inhibiting activity in fermented products.

Innovation Solution

A method involving the addition of dried and milled residue materials such as sunflower seeds, wheat, and sesame residue into a culture medium for lactic acid bacteria fermentation, followed by specific hydrolysis and fermentation steps, to produce a fermented crude extract with ACE inhibiting activity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If chemical synthesized drugs are used to inhibit ACE activity, then blood pressure control is effective, but side effects such as dizziness, vomiting, fatigue, dry cough, high potassium, and kidney failure occur

Engineering Contradiction:
Improveblood pressure control effectivenessVSAvoidside effects
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the chemical nature of the ACE inhibiting agent from synthetic drugs to naturally derived fermented crude extract. By altering the source and composition parameters (using lactic acid bacteria fermentation of residue materials), the therapeutic effect is maintained while eliminating the harmful side effects associated with synthetic drugs

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses inexpensive residue materials (agricultural by-products) as the base for fermentation instead of expensive synthetic drug production. These residue materials serve as a sustainable, low-cost substrate that can be readily disposed of or composted after extraction, replacing costly pharmaceutical manufacturing

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

2Reliability

If natural materials are added to culture medium for LAB fermentation, then ACE inhibiting activity is enhanced, but the choices for materials are limited

Engineering Contradiction:
ImproveACE inhibiting activityVSAvoidmaterial selection range
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent establishes a universal fermentation system using lactic acid bacteria that can process multiple types of residue materials (vegetable, fruit, grain, and other agricultural by-products). This multi-functional approach allows the same fermentation methodology to be applied across diverse material types, greatly expanding the versatility of material selection while maintaining enhanced ACE inhibiting activity

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

Solution Approach 2:

The patent employs composite materials by combining residue materials with culture medium components for LAB fermentation. This composite approach creates a synergistic system where the residue material provides substrate diversity and the culture medium provides optimal fermentation conditions, thereby expanding material options while ensuring consistent ACE inhibiting effects

Inventive Principle:
Principle #40Composite materials

3Reliability

If residue materials are used for fermentation, then health-care products with ACE inhibiting activity are produced, but the production process requires multiple steps including drying, milling, hydrolysis, and fermentation

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-processing the residue materials through drying and milling before fermentation. These preliminary steps prepare the materials in an optimal state for subsequent enzymatic hydrolysis and fermentation, ensuring consistent quality and ACE inhibiting activity in the final product while streamlining the overall production process

Inventive Principle:
Principle #10Preliminary action
