Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a porous aerogel structure is used to increase surface area and capacity, then the capacitor capacity is improved, but the method for forming and connecting external electrodes to internal electrodes is not established
Solution Approach 1:
The patent introduces a conductive layer as an intermediary between the porous aerogel internal electrode and the external electrode. This conductive layer fills the pores of the aerogel and provides a continuous conductive path, enabling effective electrical connection while maintaining the high surface area benefits of the porous structure. The intermediary conductive layer resolves the contradiction by allowing the porous structure to retain its capacity-enhancing properties while establishing a manufacturable electrode connection method.
2Area of moving object
If a multilayer structure of metal/dielectric/metal is formed on aerogel using ALD, then high surface area per unit volume is achieved, but the connection between external and internal electrodes remains unresolved
Solution Approach 1:
The patent merges the external electrode formation process with the internal electrode connection by applying a conductive layer that simultaneously serves as the internal electrode material filling the aerogel pores and as the connection interface for external electrodes. This merging of functions reduces device complexity by eliminating the need for separate connection structures while maintaining the high surface area characteristics achieved through the multilayer ALD process.
