Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If non-terrestrial network communication is used to provide wide area coverage, then coverage area is improved, but communication reliability deteriorates in discontinuous coverage environments
Solution Approach 1:
The patent merges terrestrial and non-terrestrial communication networks into a unified dual-mode communication system. The terminal device can switch between terrestrial base station communication and non-terrestrial base station communication, combining the wide coverage advantage of non-terrestrial networks with the high reliability of terrestrial networks to achieve both extended coverage and maintained communication reliability.
2Area of stationary object
If non-terrestrial network communication is used to extend coverage beyond terrestrial network areas, then coverage extension is improved, but communication continuity deteriorates in areas with obstacles
Solution Approach 1:
The patent implements dynamic communication mode switching between terrestrial and non-terrestrial networks based on real-time coverage conditions and obstacle presence. The terminal device dynamically selects the appropriate communication mode to maintain continuous connectivity, adapting to changing environmental conditions such as tunnel entry or satellite visibility changes.
3Area of stationary object
If V2X communication is implemented in non-terrestrial network areas, then wide area V2X coverage is improved, but communication reliability deteriorates due to longer propagation distance
Solution Approach 1:
The patent creates a universal communication framework that supports V2X applications across both terrestrial and non-terrestrial networks. The system provides multi-functional communication capabilities, allowing V2X services to operate reliably in diverse environments by selecting the appropriate network type based on location and requirements, ensuring both wide coverage and high reliability for safety-critical applications.
