Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional wireless infrastructure is used to serve increasing number of portable devices, then coverage area is maintained, but bandwidth capability becomes insufficient
Solution Approach 1:
The patent segments the wireless network into macrocells for broad coverage and small cells (microcells, picocells) for localized high-capacity service. This segmentation allows the system to simultaneously serve the increasing number of portable devices while maintaining adequate bandwidth capability through distributed access points.
Solution Approach 2:
The patent introduces a vertical dimension to network deployment by utilizing multiple layers (macro layer for coverage, small cell layer for capacity) and three-dimensional space for antenna placement. This dimensional expansion enables the system to handle increased device density without sacrificing bandwidth.
2Productivity
If higher bandwidth capability is implemented in wireless infrastructure, then service quality is maintained, but system complexity increases
Solution Approach 1:
The patent designs small cells to serve multiple functions simultaneously: providing high-bandwidth capacity, offering mobile broadband access, and delivering localized coverage. This multi-functionality reduces overall system complexity by consolidating multiple network functions into single nodes.
Solution Approach 2:
The patent employs dynamic parameter adjustment including adaptive modulation, variable coding rates, and real-time resource allocation. These parameter changes enable the system to maintain service quality across varying conditions without requiring complex fixed infrastructure for every possible scenario.
3Productivity
If small cell deployment is pursued to provide additional mobile bandwidth, then bandwidth capability is improved, but deployment cost and complexity increase
Solution Approach 1:
The patent utilizes standardized small cell templates and modular designs that can be replicated across different locations. This copying approach reduces deployment costs by eliminating the need for custom infrastructure at each site while maintaining the bandwidth capabilities required for mobile services.
Solution Approach 2:
The patent implements a nested network architecture where small cells are deployed within or adjacent to macrocells, with small cells serving as complementary nodes. This nesting allows incremental deployment starting from existing infrastructure, reducing overall deployment cost and complexity.
