Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ground base stations are deployed in mountainous areas with limited line of sight, then aircraft control and data transfer are enabled in challenging geographical conditions, but communication stability deteriorates due to frequency confusion and signal interference when aircraft move between grids
Solution Approach 1:
The service area is divided into multiple grids, each with its own ground base station. The aircraft continuously monitors signal quality from multiple grids and switches to the optimal grid when conditions change, ensuring stable communication throughout the mountainous region without frequency confusion.
Solution Approach 2:
The system dynamically adjusts frequency allocation and base station selection based on real-time aircraft position, data transfer volume, and signal quality. Frequency bands are reconfigured on-demand rather than being static, maintaining communication reliability as the aircraft moves between grids.
2Productivity
If frequency bands are allocated based on data transfer volume and grid information, then interference is minimized and communication efficiency is improved, but system complexity increases due to dynamic frequency configuration requirements
Solution Approach 1:
Frequency allocation parameters are dynamically adjusted based on data transfer volume requirements and grid position. The system changes frequency bands, bandwidth allocations, and power levels in response to varying communication demands, optimizing efficiency without requiring complex manual configuration.
Solution Approach 2:
The electronic apparatus on the aircraft automatically monitors communication quality, determines optimal frequency allocations, and executes frequency changes without external intervention. The system self-configures based on predefined criteria related to data transfer volume and grid information, reducing operational complexity.
3Area of stationary object
If directional and omnidirectional antennas are used to maintain line of sight, then communication coverage is improved in mountainous areas, but device complexity and interference management become more challenging
Solution Approach 1:
The system combines directional and omnidirectional antennas in a unified antenna system that automatically selects or switches between modes based on aircraft position and communication requirements. This integrated approach expands coverage area while managing complexity through centralized control logic.
