Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If low impedance coatings such as TiN or fractal Ir-coatings are applied on the electrode surface, then the double layer capacitance is increased, but the coating adhesion is limited and detached parts can cause inflammation
Solution Approach 1:
The invention extracts and removes the coating layer from the electrode structure, transitioning from a coated electrode to a monolithic electrode with laser-structured surface. This eliminates the coating detachment problem entirely while maintaining the capacitance enhancement through the laser-created hollow line pattern on the monolithic substrate surface.
2Ease of manufacture
If existing technologies of assembling and structuring electrodes are used, then the electrode can be manufactured, but the process is highly energy consuming and work intensive
Solution Approach 1:
The invention replaces complex mechanical assembly processes with a direct laser structuring approach on a monolithic substrate. The continuous laser ablation process creates the hollow line pattern in one integrated step, eliminating multiple mechanical manufacturing steps and significantly reducing energy consumption and production complexity.
3Ease of manufacture
If existing technologies of assembling and structuring electrodes are used, then the electrode can be manufactured, but the process requires many different materials or devices making it costly
Solution Approach 1:
The invention merges multiple manufacturing operations into a single laser structuring process on a monolithic substrate. The continuous laser ablation simultaneously creates the hollow line pattern and defines the electrode structure, eliminating the need for separate coating application, assembly, and structuring steps that would require multiple materials and devices.
