Solution Overview
Problem
The existing methods for manufacturing electrical connection components using graphene oxide are costly due to the need for separate steps to obtain and reduce graphene oxide, which increases production costs despite offering excellent electrical conductivity.
Innovation Solution
The use of a graphene oxide film with a thickness of 1 nm to 50 nm, formed by an electrophoretic deposition method, which provides low electrical resistance while maintaining the high chemical stability and mechanical strength of graphene oxide, thereby reducing production costs and improving contact reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If graphene oxide is reduced to obtain reduced graphene oxide for electrical contacts, then electrical conductivity is improved, but production cost increases due to additional reduction steps
Solution Approach 1:
The patent extracts only the essential functional property (electrical conductivity) needed for the electrical contact by controlling graphene oxide thickness to 1-50 nm, rather than performing full reduction to graphene. This selective approach achieves the necessary conductivity while avoiding costly reduction processes.
Solution Approach 2:
The patent changes the critical parameter of graphene oxide thickness to 1-50 nm range. By optimizing this dimensional parameter, the material achieves sufficient electrical conductivity for contact applications without requiring chemical reduction, thus lowering production costs while maintaining reliability.
2Reliability
If precious metal plating is applied to electrical contacts, then wear resistance and electrical conductivity are improved, but production cost increases
Solution Approach 1:
The patent replaces expensive precious metals with a cheaper alternative (graphene oxide) that achieves comparable functional performance. The thin film nature (1-50 nm) makes it cost-effective while providing sufficient durability for electrical contact applications.
Solution Approach 2:
The patent uses graphene oxide as a composite coating material on the electrical contact surface, combining the benefits of low cost with adequate wear resistance and electrical conductivity, replacing traditional precious metal plating.
3Stability of the object's composition
If graphene oxide film thickness is increased, then chemical stability and mechanical strength are improved, but electrical resistance increases
Solution Approach 1:
The patent optimizes the thickness parameter to a specific range (1-50 nm) where the material simultaneously achieves adequate chemical stability, mechanical strength, and acceptable electrical resistance. This narrow optimal range balances all three competing requirements.
Solution Approach 2:
The patent applies a thin film (1-50 nm) that is sufficient to provide chemical stability and mechanical strength, but not so thick as to excessively increase electrical resistance. The partial application achieves the minimum necessary protection while maintaining electrical performance.

AI summary
An electrical connection component includes a connecting part that is electrically conductive, and an electrical contact on at least a part of a surface of the connecting part, the electrical contact including a graphene oxide film. The graphene oxide film is graphene oxide or a stack of graphene oxide, and a thickness of the graphene oxide film is 1 nm or more and 50 nm or less. The electrical connection component may be either a male terminal or a female terminal.
