Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manufacturing processes are used for Z-directed components, then individual component production is achieved, but mass production capability and productivity are insufficient
Solution Approach 1:
The patent merges multiple manufacturing operations into a single continuous extrusion process. Multiple materials (conductive, resistive, dielectric) are extruded simultaneously through a multi-channel die to form complete Z-directed components in one continuous operation, enabling mass production while maintaining manufacturing simplicity
Solution Approach 2:
The continuous extrusion process operates without interruption, continuously forming Z-directed components as the extruded materials are deposited and cured in place on the PCB. This continuous operation eliminates discrete manufacturing steps and enables high-volume production
2Quantity of substance
If component densities are increased, then space utilization is improved, but manufacturing precision and integration complexity increase
Solution Approach 1:
Multiple functional elements (conductors, resistors, dielectric layers) are combined into a single integrated Z-directed component formed by simultaneous multi-material extrusion. This integration achieves high component density while maintaining manufacturing precision through a unified continuous process
Solution Approach 2:
The multi-channel die provides different materials to specific locations within the extruded component, creating locally optimized structures with appropriate electrical properties (conductive, resistive, or dielectric) in each region, enabling precise control of component characteristics at high density
3Reliability
If higher frequencies of operation are achieved, then performance is improved, but manufacturing complexity and process control difficulty increase
Solution Approach 1:
The extrusion process deposits materials with specific electrical properties (conductive, resistive, dielectric) in predetermined patterns and locations within the Z-directed component. This local material placement creates optimized electrical structures for high-frequency operation while maintaining relatively simple manufacturing
Solution Approach 2:
The Z-directed component is formed as a composite structure integrating multiple materials (conductive paste, resistive material, dielectric material) in a single extruded body. This composite construction enables high-frequency performance through optimized material distribution while keeping the manufacturing process unified and manageable
