Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an existing AAS adopts two arrays of antennas with two dual-band signals receiving capability, then the network performance gain is improved, but the uplink network performance requirement cannot be met due to limited signal receiving capacity
Solution Approach 1:
The patent segments the signal receiving process by introducing a combining-splitting network that divides received signals into different bands and directs them to appropriate receiving units. This allows the system to handle multiple bands simultaneously while increasing overall receiving capacity beyond the limitations of traditional two-array configurations.
Solution Approach 2:
The patent implements multi-functionality by designing receiving units that can handle both single-band and dual-band signals through the combining-splitting network. The same hardware infrastructure serves multiple purposes: receiving single-band signals directly and receiving dual-band signals by separating them through the combining network, thereby increasing versatility without proportionally increasing hardware complexity.
2Productivity
If multiple transceiving modules are added to increase signal receiving capacity, then uplink network performance is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple receiving functions into a unified architecture using the combining-splitting network. Instead of adding separate independent transceiving modules for each band, the system combines signal reception, splitting, and routing into an integrated structure that achieves multiple-band receiving capability while reducing overall system complexity.
Solution Approach 2:
The combining-splitting network acts as an intermediary that mediates between the antenna arrays and the receiving units. It receives signals from the antenna, separates them by frequency band, and directs them to appropriate receiving units, thereby simplifying the interface between different system components and reducing overall complexity.
3Adaptability or versatility
If a combining-splitting network is introduced to separate radio-frequency signals into different bands, then signal receiving versatility is improved, but device complexity increases
Solution Approach 1:
The combining-splitting network exploits parameter changes in signal frequency to achieve band separation. By utilizing the frequency parameter difference between bands, the network can route signals to appropriate receiving units based on their frequency characteristics, achieving versatile multi-band handling through a relatively simple frequency-selective structure.
