Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mycelium materials are grown as networks of enmeshed hyphae, then they exhibit bioefficiency and low environmental footprint, but they have poor mechanical qualities including susceptibility to delamination and tearing under stress

Engineering Contradiction:
Improvemechanical qualityVSAvoidresistance to delamination and tearing
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent applies composite materials by combining mycelium with various reinforcing elements including particles, fibers, networks of fibers, solid matrix bonding agents, and nonwoven lamina. This creates a composite structure where the mycelium network is integrated with additional materials to enhance mechanical strength and resistance to delamination and tearing while maintaining the bioefficiency and environmental benefits of mycelium.

2Reliability

If mycelium materials are grown as networks of enmeshed hyphae, then they exhibit bioefficiency and low environmental footprint, but they have non-uniform aesthetic qualities

Engineering Contradiction:
Improveaesthetic qualityVSAvoiduniformity of aesthetic properties
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent applies local quality by incorporating particles, fibers, and other additives into the mycelium network to create specific local aesthetic properties. These additives can be distributed throughout the material or concentrated in specific regions to achieve desired aesthetic effects while maintaining uniformity through controlled incorporation methods.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent addresses non-uniform aesthetic qualities by using homogenization processes and uniform distribution methods for incorporating particles, fibers, and other additives into the mycelium network. This ensures consistent aesthetic properties throughout the material while preserving the natural appearance and texture of the mycelium structure.

Inventive Principle:
Principle #33Homogeneity
