Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If chemical synthesis assembly or inkjet printing is used to construct electrodes, then electrodes can be fabricated, but the process becomes complicated with poor repeatability and low processing precision
Solution Approach 1:
The patent replaces chemical synthesis assembly and inkjet printing processes with ultrafast laser direct writing technology. The laser system directly deposits and patterns electrode materials through controlled ablation and deposition, eliminating the need for complex chemical processes and multiple assembly steps, thereby simplifying the overall manufacturing process while improving precision and repeatability
Solution Approach 2:
The patent utilizes controllable laser parameters (power, pulse duration, scanning speed, focal position) to precisely regulate the electrode construction process. By adjusting these parameters, the system achieves high manufacturing precision in electrode patterning, material deposition thickness control, and feature size definition, while maintaining a simplified single-step processing approach
2Productivity
If conventional electrode construction methods are used, then electrodes can be formed, but processing efficiency and quality are low
Solution Approach 1:
The patent employs continuous laser scanning with real-time material deposition and processing in a single uninterrupted operation. The ultrafast laser beam continuously writes the electrode patterns while simultaneously depositing and sintering the material, eliminating the need for separate processing steps and significantly improving both productivity and processing quality through continuous actionable processing
Solution Approach 2:
The patent performs preliminary material deposition and preliminary pattern formation in the same processing step before final sintering and completion. The laser first deposits the electrode material in the desired pattern configuration, then immediately sinters it in the same scanning pass, ensuring both high efficiency and precise quality control without requiring intermediate handling or separate processing operations
