Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wireless devices operate in low-energy consumption mode in remote areas, then energy efficiency is improved, but the ability to receive timely updates and security patches deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-configuring devices with update check intervals and maintaining update availability on the network side. Devices are configured to wake up periodically to check for updates without requiring continuous connection, allowing update delivery to be prepared in advance while devices remain in low-power mode most of the time.
Solution Approach 2:
The system implements feedback mechanisms where devices report their operational status and update reception confirmation back to the network. The network monitors device responses to update requests and adjusts future update delivery strategies based on this feedback, ensuring reliable delivery even when devices are in low-power mode.
2Area of stationary object
If satellite communications are used to provide backup connectivity in remote areas, then connectivity coverage is improved, but system complexity increases
Solution Approach 1:
The system makes the communication infrastructure universal by enabling devices to operate in multiple modes: terrestrial network mode when available, satellite mode when terrestrial coverage is absent, and hybrid mode for seamless transition. The same device and network infrastructure handle both terrestrial and satellite communications without requiring separate dedicated systems.
Solution Approach 2:
The patent introduces an intermediary system component that manages the complexity of satellite communication integration. This intermediary layer handles the coordination between terrestrial and satellite networks, managing mode transitions and ensuring seamless connectivity without exposing the full complexity to end devices or users.
3Loss of time
If devices frequently check for updates in remote areas, then update timeliness is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic action by configuring devices to check for updates at predetermined intervals rather than continuously. This periodic checking mechanism balances the need for timely updates with energy conservation, allowing devices to remain in low-power mode between check cycles while ensuring updates are received within acceptable timeframes.
Solution Approach 2:
The system applies dynamics by adjusting update check frequencies and power mode transitions based on real-time conditions. The network monitors device status and environmental factors to dynamically optimize the balance between update timeliness and energy consumption, adapting the checking schedule rather than following a fixed rigid pattern.

AI summary
Systems and methods are provided for managing connection to a non-terrestrial network (NTN). The system determines whether wireless devices are within the NTN coverage, and the detected devices are configured to enter a low-energy consumption mode. The system periodically checks for any required updates to the wireless devices, such as firmware/software updates or security patches. If an update is necessary, a message is sent to the wireless devices to switch the device from the low-energy consumption mode to a setup mode. An update is sent to the device via the NTN, and, upon reception of the update, the processor executes the required update on the corresponding wireless device. Once the desired update is made, the device is instructed to reenter the low-energy consumption mode, and the device modification is registered.
