Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing mycelial sheets are either time-consuming or operationally complex, and there is a need for a more efficient and straightforward process.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solid-state cultivation is used to produce mycelial sheet, then the mycelial sheet can be formed on a solid culture medium, but the production process becomes more time-consuming
Solution Approach 1:
The patent changes the cultivation parameter from solid-state to liquid-state medium, which fundamentally alters the growth dynamics. The liquid medium allows for better nutrient distribution and oxygen transfer, accelerating mycelial growth rate while maintaining sheet formation capability through surface tension and evaporation effects
2Productivity
If shaking cultivation in liquid medium followed by filtration is used, then the mycelial sheet can be obtained from liquid culture, but the operation becomes more complicated
Solution Approach 1:
The patent extracts and utilizes the mycelial sheet that naturally forms on the liquid medium surface during cultivation, eliminating the need for complex filtration operations. The mycelial sheet spontaneously accumulates at the air-liquid interface, allowing for simple decanting or skimming to separate the product from the culture medium
3Strength
If cellulose is added to improve mechanical property, then the tensile strength increases, but the medium composition becomes more complex
Solution Approach 1:
The patent utilizes cellulose that is already present in the liquid medium (from plant-based substrates or bacterial production) to enhance mycelial sheet strength. The mycelia naturally bind with the cellulose fibers during growth, creating a composite structure that improves mechanical properties without requiring additional cellulose addition or complex medium formulation
