Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional slow-wave structures use a split design with separate components, then assembly flexibility is improved, but manufacturing precision and consistency deteriorate due to processing and assembly errors
Solution Approach 1:
The patent merges the tube housing, slow-wave line, and support portions into a single integrated structure manufactured as one piece using planarization and 3D printing processes. This eliminates the interfaces between separate components, thereby removing processing and assembly errors while maintaining structural flexibility through the integrated design
2Ease of manufacture
If conventional slow-wave structures use multiple separate components, then ease of manufacture is improved, but productivity deteriorates due to extended production cycles
Solution Approach 1:
The patent combines multiple components into a single integrated structure that can be manufactured in one production cycle using planarization and 3D printing processes, eliminating the need for separate fabrication and assembly steps, thereby significantly shortening the production cycle while maintaining manufacturing capability
Solution Approach 2:
The patent changes the manufacturing parameters and processes by adopting planarization and 3D printing technologies, which enable the production of complex integrated structures in a single cycle, thereby improving productivity without sacrificing manufacturing ease
3Ease of manufacture
If conventional slow-wave structures use traditional assembly methods, then ease of manufacture is improved, but reliability deteriorates due to low yields and inconsistency
Solution Approach 1:
The patent merges all components into a single integrated structure manufactured through planarization and 3D printing processes, eliminating assembly operations that introduce variability and errors, thereby improving yield and consistency while maintaining manufacturing simplicity
Solution Approach 2:
The patent replaces traditional mechanical assembly methods with integrated manufacturing processes (planarization and 3D printing), which create monolithic structures without assembly interfaces, thereby eliminating sources of inconsistency and improving reliability
