Solution Overview

Problem

Existing methods for detoxifying lacquer sap from lacquer trees often destroy the pharmaceutical ingredients and allergenic components, making them unsuitable for medical and biological applications, and lack a nature-friendly approach for preserving these ingredients.

Innovation Solution

A method using fermented rice bran and malt juice to detoxify lacquer sap at controlled temperatures, preserving the pharmaceutical ingredients and avoiding high-temperature processes, which involves cutting and preparing lacquer tree stems or sprouts, fermenting with malt juice, and ripening to create a non-toxic lacquer for use in food products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If high-temperature roasting or carbonizing is used to detoxify lacquer, then the toxicity of urushiol is neutralized, but the pharmaceutical ingredients and allergenic components are destroyed

Engineering Contradiction:

Improvetoxicity of urushiolVSAvoidpharmaceutical ingredients

Core Design Contradiction:

Object-affected harmful factorsVSLoss of substance

Solution Approach 1:

The patent changes the detoxification parameter from high-temperature thermal processing to low-temperature enzymatic processing using malt amylase and fermented rice bran. This parameter change allows detoxification of urushiol while preserving pharmaceutical ingredients that would otherwise be destroyed by high-temperature roasting or carbonizing

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the mechanical/thermal system (high-temperature roasting or carbonizing) with a biochemical system (enzymatic action of malt amylase and fermented rice bran). This substitution enables selective detoxification of urushiol without the non-selective destruction caused by high-temperature processing

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If high-temperature carbonizing is used to detoxify lacquer, then the toxicity is neutralized, but all 100 natural pharmaceutical ingredients are removed

Engineering Contradiction:

Improvetoxicity of urushiolVSAvoidnatural pharmaceutical ingredients

Core Design Contradiction:

Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The patent changes the processing temperature parameter from high-temperature (200°C or more) to low-temperature fermentation (20°C to 25°C for 70 hours or more). This parameter change enables selective action on urushiol while preserving the quantity and integrity of natural pharmaceutical ingredients

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces malt amylase and fermented rice bran as intermediary substances that mediate the detoxification process. These intermediaries selectively target urushiol for breakdown while leaving pharmaceutical ingredients intact, avoiding the non-selective destruction caused by direct high-temperature carbonizing

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If direct intake of liquid lacquer is performed, then the pharmaceutical and biological activity is utilized, but adverse side effects such as rash and pruritus occur

Engineering Contradiction:

Improvepharmaceutical and biological activityVSAvoidadverse side effects

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful property of urushiol (toxicity causing rash and pruritus) into a beneficial process by using urushiol-containing lacquer as the substrate for enzymatic detoxification. The same substance that causes harm becomes the material to be processed, transforming the harmful lacquer into a safe, non-toxic product that retains pharmaceutical activity

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
