Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a 3G/4G scheme with RRU+BBU architecture is used for high frequency 5G base station, then the base station can be constructed with modular components, but the network stability and reliability deteriorate due to multiple physical interfaces and processing modules

Engineering Contradiction:
Improvemodular construction capabilityVSAvoidnetwork stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges the transmission signal processing and coverage signal processing into a single integrated processing unit. The processing unit integrates RF down-conversion, filtering, amplification, analog-to-digital conversion, and baseband processing functions that were previously separated across multiple modules (RRU and BBU). This consolidation eliminates multiple physical interfaces and inter-module connections, thereby improving network stability and reliability while maintaining modular deployability through the unified processing unit design.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If multiple processing modules are involved in data conversion between core network and user side, then signal processing capability is enhanced, but connection stability among modules deteriorates

Engineering Contradiction:
Improvesignal processing capabilityVSAvoidconnection stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The patent combines multiple separate processing modules (RF processing module, baseband processing module, data processing module) into a single integrated processing unit. This unit performs all necessary operations including RF down-conversion, filtering, amplification, analog-to-digital conversion, and baseband processing in one cohesive system. By eliminating the need for multiple inter-module connections and data conversions between separate units, the patent maintains signal processing capability while significantly improving connection stability.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If optical fiber connection is required between RRU and BBU, then transmission connectivity is established, but device complexity and management difficulty increase

Engineering Contradiction:
Improvetransmission connectivityVSAvoidphysical interface complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent integrates the functions previously requiring separate RRU and BBU units with optical fiber connections into a single processing unit. The processing unit incorporates all necessary processing functions internally, eliminating the need for external optical fiber connections between separate units. This reduces physical interface complexity and simplifies deployment while maintaining full transmission and coverage capabilities through the unified architecture.

Inventive Principle:
Principle #5Merging (Combining)
