Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional printed circuit board technology is used for microwave device prototyping, then manufacturing precision and reliability are maintained, but prototyping time increases significantly to several weeks or months
Solution Approach 1:
The invention divides the microwave device into separate functional layers (conductor patterns on dielectric sheets) that can be independently fabricated and then assembled. This segmentation allows parallel processing of different circuit configurations, enabling rapid prototyping by simply swapping dielectric sheets rather than remanufacturing entire PCBs.
Solution Approach 2:
The base structure with conductor patterns serves multiple functions: it provides the circuit framework, mounting substrate, and electrical connection points for various dielectric sheet configurations. This universal base allows the same physical structure to support multiple different circuit designs by changing only the dielectric sheets.
2Reliability
If multiple prototype printed circuit boards are manufactured to test different circuit configurations, then circuit design verification is achieved, but manufacturing cost and complexity increase
Solution Approach 1:
By separating the conductor patterns from the dielectric material, the invention allows independent optimization of each component. The conductor patterns can be precisely fabricated once on a universal base, while different dielectric sheets with varying metallization patterns can be quickly produced and tested, reducing overall manufacturing complexity.
Solution Approach 2:
Instead of manufacturing multiple unique PCB prototypes, the invention uses a single master base structure that can be copied or replicated with different dielectric sheets. This allows rapid production of circuit variations through sheet swapping rather than complete PCB remanufacturing.
3Volume of moving object
If electronic components are positioned close together to achieve miniaturization, then device size is reduced, but parasitic effects and signal interference increase
Solution Approach 1:
The invention allows different dielectric materials with specific electrical properties to be placed in different local regions of the circuit. By selecting dielectric sheets with appropriate material characteristics for specific circuit areas, parasitic effects can be minimized while maintaining compact dimensions.
Solution Approach 2:
The invention moves circuit design from a two-dimensional PCB surface to a multi-layered structure with conductor patterns on separate dielectric sheets. This dimensional approach allows better spatial management of electrical fields and signal paths, reducing parasitic coupling between closely positioned components.
