Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stacked antenna module with top and bottom antenna structures is used, then wireless transmission capability is improved, but interference between antenna structures occurs leading to degraded signal quality
Solution Approach 1:
An insulating connection layer is introduced between the first and second antenna structures to serve as an intermediary that provides electrical insulation while maintaining mechanical connection. This mediator prevents direct electrical contact between the stacked antenna structures, thereby reducing interference while preserving the compact stacked configuration for improved wireless transmission capability.
Solution Approach 2:
The antenna module is segmented into distinct first and second antenna structures with separate carrier substrates, each having its own feeding pins and electrode layers. This segmentation allows independent optimization of each antenna structure while maintaining physical separation through the insulating connection layer, reducing mutual interference between the stacked structures.
2Reliability
If feeding pins directly contact the antenna electrode layers, then electrical connection is achieved, but interference model increases and signal clarity decreases
Solution Approach 1:
The insulating connection layer acts as an intermediary between the feeding pins of the first antenna structure and the electrode layers of the second antenna structure. It provides the necessary electrical connection path while preventing direct contact that would cause interference, thereby maintaining signal clarity while ensuring reliable electrical connectivity.
Solution Approach 2:
The insulating connection layer is a simple, cost-effective component that provides temporary electrical insulation during the signal transmission process. This disposable-like insulating element effectively blocks interference paths without requiring complex active components, maintaining signal integrity at low cost.
