Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional preparation process is used for cathode components, then manufacturing experience and multiple process steps are required, but the process complexity increases and quality consistency deteriorates
Solution Approach 1:
The patent combines multiple traditional preparation steps (modeling, machining, heat treatment) into a single 3D printing process. The additive manufacturing process integrates material deposition, shaping, and initial densification in one continuous operation, eliminating the need for separate machining and assembly steps while maintaining or improving component quality through digital process control.
Solution Approach 2:
The patent utilizes controlled parameter changes during 3D printing, specifically adjusting laser power, scanning speed, and layer thickness to optimize the sintering process. By modifying these parameters dynamically, the process achieves consistent high-quality cathode components with controlled grain structure and density, replacing traditional empirical manufacturing approaches with precision digital control.
2Productivity
If traditional machining and heat treatment processes are used, then material removal and multiple processing steps are required, but material waste increases and production time extends
Solution Approach 1:
The patent performs preliminary digital modeling and process simulation before actual manufacturing. The 3D model includes all geometric features and internal structures that will be directly fabricated, allowing for optimization of material usage and process parameters in advance. This preliminary digital preparation eliminates the need for trial-and-error physical machining and reduces material waste by ensuring precise material placement from the start.
Solution Approach 2:
The patent replaces traditional mechanical machining processes with additive manufacturing. Instead of removing material through cutting, drilling, or grinding operations, the system builds the cathode component layer by layer through controlled material deposition and sintering. This substitution eliminates material removal waste and reduces the number of processing steps required for complex geometries.
