Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a 2D material lattice is used for proton transport, then selective transport capability is improved, but fundamental understanding and manipulation control remain elusive
Solution Approach 1:
The patent introduces a catalytic layer as an intermediary between the 2D material lattice and the environment, enabling indirect control of proton transport. The catalytic layer mediates the interaction between protons and the 2D material, making the transport process controllable while preserving the selective capability of the lattice structure.
Solution Approach 2:
The patent creates a composite structure combining 2D material lattice with catalytic materials. This composite approach integrates the selective transport properties of the 2D lattice with the catalytic activity and controllability of the catalytic layer, resolving the contradiction between selectivity and manipulability.
2Productivity
If proton transport through 2D lattice is enhanced, then energy conversion efficiency is improved, but mechanism understanding remains elusive
Solution Approach 1:
The catalytic layer serves as a mediator that enhances proton transport through the 2D lattice while providing a controllable interface for studying transport mechanisms. This intermediary structure allows for improved energy conversion efficiency while creating observable effects that can help elucidate the underlying mechanisms.
3Reliability
If catalytic material is deposited on 2D material surface, then proton conductivity is improved, but device complexity increases
Solution Approach 1:
The patent applies catalytic material locally on the surface of the 2D material lattice rather than throughout the entire structure. This localized deposition enhances proton conductivity at the critical transport interface while minimizing the overall complexity and material usage of the device.
