Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional wireless infrastructure is used to provide broadband access, then coverage area is extended, but propagation loss increases and transmission distance is limited
Solution Approach 1:
The patent uses dielectric materials as intermediary structures to guide and confine electromagnetic waves. The dielectric waveguide structure with specific permittivity values (e.g., εr=2.2 for outer layer, εr=3.5 for inner layer) acts as a mediator that reduces propagation loss by confining the electromagnetic energy within the waveguide structure, enabling longer transmission distances compared to traditional free-space propagation.
2Productivity
If macrocell base stations are deployed to cover large areas, then coverage is improved, but bandwidth capability becomes insufficient for increasing data demand
Solution Approach 1:
The patent employs segmented dielectric waveguide structures that can be deployed in distributed configurations. The waveguide system is divided into manageable sections that can be individually installed along transmission paths, allowing bandwidth enhancement to be implemented incrementally across large geographic areas without requiring complete infrastructure replacement.
Solution Approach 2:
The patent transitions from traditional two-dimensional horizontal cell deployment to a three-dimensional structure by implementing dielectric waveguides that can be positioned at various heights and orientations. This vertical dimension allows for additional bandwidth capacity while maintaining coverage area, as waveguides can be stacked or arranged in multiple spatial layers.
3Productivity
If small cell deployment is pursued to provide additional bandwidth, then bandwidth capability increases, but device complexity and infrastructure requirements increase
Solution Approach 1:
The dielectric waveguide structure serves multiple functions simultaneously: it guides electromagnetic waves, provides mechanical support, and can be integrated with existing utility infrastructure such as poles and towers. This multi-functionality reduces the need for separate components and simplifies deployment, as the same structure that provides mechanical support also serves as the waveguide for signal transmission.
