Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wireless communication services are provided by non-terrestrial networks, then coverage area is expanded to include mountainous regions, remote regions, and the sea, but communication speed becomes insufficient compared to conventional terrestrial networks
Solution Approach 1:
The patent combines terrestrial network and non-terrestrial network connections into a unified communication system. The terminal device simultaneously utilizes both network types, merging their respective strengths to achieve both wide coverage and high communication speed that neither network could provide alone.
Solution Approach 2:
The system dynamically switches between terrestrial and non-terrestrial network connections based on real-time conditions such as location, signal quality, and service requirements. This dynamic adaptation allows the terminal to optimize communication speed while maintaining coverage in diverse environments.
2Area of stationary object
If wireless communication services are provided by non-terrestrial networks, then coverage is extended to wide areas including remote regions, but communication reliability becomes insufficient compared to terrestrial networks
Solution Approach 1:
The patent changes the network connection parameters dynamically by switching between terrestrial and non-terrestrial networks based on service requirements and environmental conditions. This parameter adjustment optimizes both coverage area and communication reliability for different operational scenarios.
Solution Approach 2:
The system employs dynamic connection management that continuously monitors and adapts the communication path between terrestrial and non-terrestrial networks, ensuring reliable service delivery across wide coverage areas by selecting the most stable connection available.
3Speed
If a terminal establishes wireless connections between terrestrial and non-terrestrial networks, then communication speed is improved, but device complexity increases
Solution Approach 1:
The patent introduces a network side device as an intermediary that manages the complexity of coordinating terrestrial and non-terrestrial network connections. This mediator handles the complex tasks of connection establishment, resource allocation, and switching, thereby improving communication speed without burdening the terminal device with excessive complexity.
