Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If full digital systems are used to enable flexible multi-network operator routing, then adaptability and routing flexibility are improved, but device complexity and cost increase

Engineering Contradiction:
Improverouting flexibilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system divides the digital signal processing functions into separate modules: a central hub that performs digital processing and carrier bundle formation, and remote units that perform only analog signal relay. This segmentation reduces the complexity of individual remote units while maintaining overall system flexibility through centralized digital control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces expansion units as intermediary components between the central hub and remote units. These expansion units include coverage area modules that act as mediators to distribute carrier bundles to multiple remote units, enabling flexible routing without requiring each remote unit to have full digital processing capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple network operators share the same DAS with full digital processing at each remote unit, then adaptability to different operators is improved, but the number of transceivers and costs increase

Engineering Contradiction:
Improvemulti-operator capabilityVSAvoidnumber of transceivers
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The system merges the digital signal processing functions into a single central hub, where carrier bundles from multiple network operators are formed and processed. This consolidation allows multiple operators to share the same physical infrastructure with a single set of transceivers at the hub, eliminating the need for multiple transceivers at each remote unit while maintaining multi-operator capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The central hub is designed as a universal platform that can handle signals from multiple network operators simultaneously. The hub forms carrier bundles that can be distributed to various remote units, making the system multi-functional and capable of serving different operators without requiring operator-specific dedicated equipment at each remote unit.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If digital signal processing is performed at each remote unit to enable flexible routing, then routing flexibility is improved, but processing complexity and power consumption increase

Engineering Contradiction:
Improverouting flexibilityVSAvoidsignal processing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex digital signal processing functions from the remote units and concentrates them in the central hub. The remote units are simplified to perform only analog signal relay operations, significantly reducing their processing complexity while the central hub handles all digital carrier bundle formation and routing decisions.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system implements dynamic routing flexibility through centralized control at the hub, where carrier bundles can be dynamically assigned to different coverage areas and remote units based on real-time network conditions. This dynamic allocation is performed at the hub rather than requiring complex local processing at each remote unit, maintaining flexibility while reducing device complexity.

Inventive Principle:
Principle #15Dynamics
