Solution Overview

Problem

Conventional material production processes are energy-intensive, lead to environmental pollution, and deplete limited raw materials, while traditional grown materials like trees and fungi require extensive time and resources, and synthetic materials are non-biodegradable.

Innovation Solution

Culturing filamentous fungi, specifically Basidiomycetes, to produce low-density, chitinous materials that can replace woods and foamed plastics by controlling environmental conditions to shape the fungal fruiting bodies into desired forms, reducing post-processing waste and energy consumption.

Engineering Contradictions & Design Principles

Solution Approach 1:

The patent changes the fundamental chemical composition parameters from petroleum-based polymers to fungal-derived chitin and beta-glucan, transforming the material from non-biodegradable to biodegradable while maintaining structural integrity through controlled fungal growth conditions

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs fungi as a temporary, renewable biological system that can be grown, harvested, and composted, replacing permanent synthetic materials with a cyclic biological material that returns to the environment, embodying the disposable principle through biodegradability

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Productivity

If conventional grown materials (trees, crops) are used, then renewable and biodegradable materials are produced, but production time and resource consumption increase

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent optimizes growth parameters including temperature (20-30°C), humidity (80-95% RH), and substrate composition to accelerate fungal metabolism and growth rate, reducing production time from years (trees) to weeks (fungal materials) while maintaining material properties

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent prepares substrates with pre-balanced nutrients and growth factors before inoculation, and controls environmental conditions in advance to optimize fungal growth from the outset, eliminating the need for extensive fertilization and resource input during the growth process

Inventive Principle:

Principle #10Preliminary action

3Productivity

If fungal materials are grown to replace woods and foams, then production time is reduced and environmental impact is minimized, but manufacturing precision and structural consistency must be maintained

Engineering Contradiction:

AI summary

The method of growing a fungal fruiting body requires exposing a mycelium of a desired organism type to environmental conditions sufficient to induce fruiting of fungal primordium in the organism type followed by enclosing the fungal primordium within a mold of a designated shape representing a near net shape volume of a desired final product. The fungal primordium is allowed to grow and fill the mold to form a mass of fungal tissue equivalent in shape to the designated shape of the mold after which the mass of fungal tissue is removed from the mold and dried.
