Solution Overview
Problem
Mycelium-based materials face challenges in achieving equivalent product strength, integrity, and lifespan to traditional textile materials while maintaining environmental sustainability, with issues such as color and textural variations and brittleness.
Innovation Solution
A method involving the removal of an upper portion of the mycelium sheet or panel material, followed by rinsing, to eliminate primary and secondary metabolites, which includes compressing and rendering the material inert, thereby exposing a secondary surface for further processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the upper portion of the growing mycelium sheet is removed to eliminate metabolites causing color and textural variations, then the uniformity and appearance of the final textile product is improved, but an additional processing step is required increasing manufacturing complexity
Solution Approach 1:
The upper portion of the mycelium sheet is removed during the growth phase before harvest, rather than after. This preliminary action eliminates metabolites that cause color and textural variations before they can affect the final product, simplifying subsequent processing steps while improving uniformity
Solution Approach 2:
The problematic upper portion containing high concentrations of metabolites is physically extracted and removed from the mycelium sheet. This extraction eliminates the source of color and textural variations, allowing the remaining base layer to be processed into a more uniform textile product
2Object-affected harmful factors
If mycelium-based materials are used as alternatives to traditional textile materials, then environmental sustainability is improved, but product strength and integrity comparable to traditional materials are not achieved
Solution Approach 1:
The mycelium sheet is compressed under controlled parameters to increase density and mechanical strength. By adjusting compression force, duration, and moisture content, the material achieves strength levels comparable to traditional textiles while maintaining its sustainable, bio-based composition
Solution Approach 2:
The mycelium-based material is combined with natural binders or treated with eco-friendly cross-linking agents to create a composite structure that enhances strength and integrity. This allows the material to meet performance requirements while preserving its environmental sustainability
3Strength
If mycelium sheet is compressed to improve density and strength, then mechanical properties are improved, but the material may become more brittle
Solution Approach 1:
Compression is performed at controlled temperature and moisture levels that prevent excessive brittleness. By optimizing these parameters, the material achieves improved mechanical strength while maintaining flexibility and resistance to cracking
Solution Approach 2:
The mycelium sheet is pre-conditioned with appropriate moisture content before compression to act as a cushioning agent. This prevents the material from becoming too brittle during and after compression, maintaining structural integrity and flexibility

Function Achieved in This Case
The method results in a smoother, less brittle, and more uniform mycelium-based textile product with reduced color and texture variations, enhancing its performance and suitability for further processing.
Implementation Method 1
the growing mycelium sheet or panel hyphae penetrate the perforated layer to create the upper portion of the growing mycelium sheet or panel material
Implementation Method 2
Such rendering may be accomplished by exposure of the growing mycelium sheet or panel material to an action comprising (or selected from the group consisting of) heating and/or drying
Implementation Method 3
Such rendering may be accomplished by exposure of the growing mycelium sheet or panel material to an action comprising (or selected from the group consisting of) heating and/or drying
Implementation Method 4
the method further includes compressing the growing mycelium sheet or panel material

AI summary
A mycelium sheet or panel material which has had an upper portion of its growing surface removed prior to or concurrently with harvest, provides a more homogeneous surface for later processing of the mycelium sheet or panel material into a mycelium-based textile. An additional rinsing step of a mycelium sheet or panel material which has had an upper portion removed provides a surface which is even more amenable to textile processing into a mycelium-based textile. Such removal and rinsing steps produce a mycelium-based sheet or panel material which provide more homogeneity, such as in color appearance or texture, thereby leading to a more homogeneous mycelium-based textile end product. By addressing and eventually removing fungal growth metabolites during the mycelial growth and harvest processes, later textile processing challenges with the mycelium-based material may be eliminated. Undesirable surface irregularities in the mycelium-based material of final textile products may also be eliminated.
