Solution Overview

Problem

Current testosterone replacement therapies have side effects, and traditional Chinese medicines for tonifying kidney and invigorating yang are not safe for long-term use, while Fructus Trichosanthis seed has limited studies on its active substances and extraction challenges.

Innovation Solution

A method to prepare a Fructus Trichosanthis polypeptide by degreasing, enzymatic hydrolysis, and multi-stage purification to obtain a safe and effective polypeptide that accelerates testosterone secretion in TM3 cells, using a combination of neutral and alkaline proteases and chromatography techniques.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional Chinese medicines are used for tonifying kidney and invigorating yang, then the therapeutic effect is achieved, but safety is compromised due to side effects from long-term use

Engineering Contradiction:
ImprovesafetyVSAvoidside effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the active polypeptide components from Fructus Trichosanthis seed through degreasing, enzymatic hydrolysis, and purification processes. This isolation of specific bioactive substances eliminates the side effects associated with traditional herbal medicines while retaining the therapeutic effects of tonifying kidney and invigorating yang.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transforms the traditional herbal medicine approach into a purified polypeptide product by changing the physical and chemical parameters during processing (degreasing, enzymatic hydrolysis, chromatography purification). This parameter transformation produces a safer, more controlled therapeutic agent with reduced side effects.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If Fructus Trichosanthis seed is used as raw material, then the source is abundant and nutritious, but the extraction process is complex and yield is low

Engineering Contradiction:
Improvepolypeptide yieldVSAvoidpreparation process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the preparation process into distinct sequential steps: degreasing to remove lipids, enzymatic hydrolysis to break down proteins into peptides, and chromatography for purification. This segmentation simplifies each individual step while achieving high overall yield and purity of the target polypeptide.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary degreasing and protein degradation steps before the main purification process. By pre-processing the Fructus Trichosanthis seed material to remove interfering substances and break down proteins, the subsequent purification steps become more efficient and yield higher quality polypeptide products.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If exogenous testosterone replacement therapy is administered, then testosterone deficiency is treated, but side effects occur

Engineering Contradiction:
ImprovesafetyVSAvoidside effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses Fructus Trichosanthis polypeptide as an intermediary substance that indirectly addresses testosterone deficiency. Rather than administering exogenous testosterone directly, the polypeptide acts as a mediator that supports endogenous testosterone production and sexual function, thereby avoiding the side effects of direct hormone replacement.

Inventive Principle:
Principle #24Intermediary (Mediator)
