Solution Overview

Problem

The existing methods for manufacturing graphene require a significant amount of catalyst, leading to increased manufacturing costs and time.

Innovation Solution

A method involving a support member with a carbon layer and a catalyst layer, where the catalyst layer is applied on top of the carbon layer, allowing for the formation of graphene and subsequent separation of the support member, which facilitates the removal of the catalyst layer, thereby reducing the amount of catalyst used.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a significant amount of catalyst is used for forming graphene, then the graphene formation process is effective, but the manufacturing cost and time increase

Engineering Contradiction:
Improvegraphene formation effectivenessVSAvoidmanufacturing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

A carbon layer is deposited on the support member before the catalyst layer is applied. This preliminary carbon layer serves as a reservoir that releases carbon during graphene formation, enabling effective graphene growth with reduced catalyst quantity and thereby reducing manufacturing time while maintaining effectiveness

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The carbon layer acts as an intermediary between the support member and the catalyst layer. It provides carbon supply to the catalyst during graphene formation, allowing the catalyst to work more efficiently with smaller amounts, thus reducing both manufacturing time and cost without compromising graphene formation effectiveness

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a significant amount of catalyst is used for forming graphene, then the graphene formation process is effective, but the manufacturing cost increases

Engineering Contradiction:
Improvegraphene formation effectivenessVSAvoidcatalyst amount
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The carbon layer is prepared in advance on the support member before catalyst application. This pre-deposited carbon layer reduces the carbon demand on the catalyst, allowing effective graphene formation with reduced catalyst quantity, thereby lowering manufacturing cost while maintaining effectiveness

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The carbon layer serves as a carbon supply intermediary that feeds carbon to the catalyst during the graphene formation process. This intermediary system enables the catalyst to work more efficiently, reducing the total catalyst amount needed and thus reducing manufacturing cost without sacrificing graphene formation effectiveness

Inventive Principle:
Principle #24Intermediary (Mediator)
