Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductive meshes in transparent electrodes protrude, leading to deteriorated contact performance and separation from the electrode, due to non-uniform protrusion heights and high production costs of ITO films.
Innovation Solution
A method involving a conductive mesh buried in a transparent electrode using a PDMS transfer unit, where the mesh is attached, pressed, and separated to prevent protrusion, utilizing various printing machines and recessed beds to ensure uniform embedding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conductive mesh is formed on a transparent electrode by printing or coating, then the production cost is reduced and flexibility is improved, but the conductive mesh protrudes from the electrode surface with non-uniform height, deteriorating contact performance
Solution Approach 1:
The conductive mesh is embedded within recesses formed in the transparent electrode surface, creating a nested structure where the mesh sits inside cavities rather than protruding outward. This nesting approach allows the mesh to be formed at lower cost while achieving uniform effective height through the recess structure.
Solution Approach 2:
Recesses are pre-formed in the transparent electrode before the conductive mesh is applied. This preliminary action ensures that when the mesh is deposited, it automatically achieves uniform embedding depth and consistent surface profile, solving the protrusion uniformity problem while maintaining cost-effectiveness.
2Ease of manufacture
If a conductive mesh is formed on a transparent electrode, then ITO film production costs are reduced, but the conductive mesh separates from the electrode due to protrusion and poor contact
Solution Approach 1:
By nesting the conductive mesh within recesses in the electrode surface, the mesh achieves better mechanical interlocking and electrical contact with the electrode. This nested configuration prevents separation while using cost-effective mesh materials instead of expensive ITO films.
Solution Approach 2:
The recess structure creates localized regions of enhanced contact between the mesh and electrode. The mesh is strategically positioned within these recesses to ensure optimal electrical connection at critical contact points, improving reliability while maintaining overall cost reduction.
