Solution Overview
Problem
Existing processes for producing articles from plant-based materials using wild-type microorganisms are inefficient, require long incubation times, and rely on harmful formaldehyde-containing adhesives, limiting flexibility and environmental safety.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wild-type microorganisms are used to produce articles from plant-based materials, then the process can be carried out with simple microorganisms, but the incubation time is long (several days) and the efficiency is limited
Solution Approach 1:
The patent applies parameter changes by genetically modifying microorganisms to overexpress adhesive proteins, fundamentally changing the biological parameters of the microorganisms. This genetic modification enables them to produce sufficient adhesive protein in much shorter time (hours rather than days), directly resolving the contradiction between production efficiency and incubation time
Solution Approach 2:
The patent employs preliminary action by pre-culturing genetically modified microorganisms to overproduce adhesive proteins before mixing them with plant-based materials. This preliminary overexpression of adhesive proteins ensures that when the mixing occurs, the bonding process happens rapidly without requiring long incubation periods, thus improving productivity while minimizing time loss
2Strength
If formaldehyde-containing adhesives are used to combine plant-based starting materials, then the materials can be bonded effectively, but harmful formaldehyde is released by the finished articles
Solution Approach 1:
The patent substitutes chemical adhesive systems (formaldehyde-based) with a biological system. Genetically modified microorganisms produce adhesive proteins that naturally bond plant-based materials through biological adhesion mechanisms. This replacement eliminates formaldehyde release while maintaining bonding strength, as the adhesive function is transferred from synthetic chemistry to biological protein expression
Solution Approach 2:
The patent applies self-service by enabling the microorganisms themselves to produce the adhesive proteins needed for bonding. The genetically modified microorganisms synthesize and secrete adhesive proteins that immediately bond the plant-based materials they are mixed with, eliminating the need for separate adhesive application and curing processes, and avoiding harmful chemical emissions
3Shape
If wild-type microorganisms are used as pore-formers to lower article density, then the article structure is improved, but the production process becomes time-consuming and less flexible
Solution Approach 1:
The patent changes the functional parameters of microorganisms through genetic modification, transforming them from slow-acting wild-types to rapidly adapting genetically modified strains. These modified microorganisms can be precisely controlled to perform specific functions (adhesive protein production, pore formation) at optimized rates, enabling flexible adjustment of article structure and density according to different application requirements without being constrained by long incubation times
