Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antennas and electronic modules are placed against the waveguide with air interface, then signal transmission is enabled, but signal power loss and standing wave feedback occur due to medium change
Solution Approach 1:
The patent embeds electronic modules directly within the dielectric material of the waveguide, creating a homogeneous medium throughout. This eliminates the air-dielectric interface that causes reflection and standing waves, as the electromagnetic waves propagate through a uniform dielectric environment without abrupt medium transitions.
Solution Approach 2:
The dielectric material serves as an intermediary that integrates both the waveguide structure and electronic modules. By embedding antennas and circuits within the dielectric blocks, the material acts as a continuous medium that couples all components, eliminating the need for air interfaces and reducing signal loss.
2Adaptability or versatility
If multiple distinct elements are used in the transmission system, then functional requirements are met, but assembly difficulties increase
Solution Approach 1:
The patent combines multiple functional elements (antennas, transmission-reception circuits, modulation-demodulation circuits, and connectors) into integrated electronic modules embedded within the dielectric waveguide. This merging reduces the number of separate components and simplifies assembly while maintaining all necessary functions.
Solution Approach 2:
The dielectric waveguide structure serves multiple functions simultaneously: it guides millimeter waves, provides mechanical support, embeds electronic modules, and interfaces with standard connectors. This multi-functionality reduces the need for separate components and simplifies the overall system architecture.
3Adaptability or versatility
If standard connectors are integrated into the transmission device, then adaptability to USB or HDMI interfaces is achieved, but device structure becomes more complex
Solution Approach 1:
The electronic modules embedded in the dielectric waveguide are designed with integrated connectors that provide universal compatibility with standard interfaces (USB, HDMI, etc.). This allows the waveguide to adapt to different connection standards without requiring separate interface components, maintaining structural simplicity while achieving broad adaptability.
