Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dual connectivity (DC) is activated to perform LTE and 5G communication simultaneously, then user throughput is improved, but power consumption increases and battery life is reduced
Solution Approach 1:
The patent implements dynamic switching between communication modes (DC and LTE-only) based on real-time conditions such as data transmission requirements and battery status. The system transitions from static DC activation to dynamic mode selection, allowing the device to adapt communication strategies to current operational needs and power availability.
Solution Approach 2:
The system changes operational parameters by switching between different communication modes (DC with both LTE and 5G, or LTE-only) based on detected conditions. When data transmission is complete or battery is low, the system changes the communication parameter from dual-connectivity to single-LTE mode, thereby reducing power consumption while maintaining necessary functionality.
2Use of energy by moving object
If dual connectivity (DC) is stopped to reduce power consumption, then battery life is extended, but data transfer time increases due to lower LTE throughput
Solution Approach 1:
The system performs preliminary actions by completing data transmission during the high-throughput DC period before switching to LTE-only mode. By anticipating the need to reduce power consumption, the system prioritizes data transfer during the available DC window, ensuring that time-sensitive transmissions are completed before the lower-throughput mode begins.
Solution Approach 2:
The patent maintains continuity of communication functionality by seamlessly transitioning between DC and LTE-only modes. The system ensures uninterrupted data transmission by completing pending transfers during DC operation and maintaining LTE connectivity for ongoing communications, thereby eliminating gaps in useful action while adapting power consumption levels.
3Use of energy by moving object
If LTE-only communication is used after stopping DC, then power consumption is reduced, but communication speed decreases to about one tenth of 5G throughput
Solution Approach 1:
The system dynamically adjusts communication speed and power consumption by switching between DC mode (high speed, high power) and LTE-only mode (lower speed, lower power). This dynamic adaptation allows the device to optimize the speed-power trade-off based on real-time conditions such as data transmission status and battery charge level.
Solution Approach 2:
The system applies partial action by using only the necessary communication mode for current needs. When full 5G speed is not required (e.g., after data transfer completion or during low-activity periods), the system reduces communication activity to LTE-only, avoiding excessive power consumption while maintaining sufficient communication capability for ongoing tasks.
4Productivity
If DC is always activated to maintain high throughput, then data transfer efficiency is improved, but battery may run out prematurely reducing user convenience
Solution Approach 1:
The system implements feedback mechanisms by monitoring battery status and data transmission progress in real-time. Based on this feedback, the system automatically adjusts communication mode, switching from DC to LTE-only when appropriate. This closed-loop control ensures that high-throughput DC operation is maintained only when necessary and beneficial, preventing premature battery depletion while preserving user convenience.
Solution Approach 2:
The patent enables the communication system to self-regulate by automatically switching between DC and LTE-only modes based on detected conditions such as data transmission completion and battery status. The system serves itself by making intelligent decisions about mode switching without requiring manual user intervention, thereby optimizing both data transfer efficiency and battery life autonomously.

AI summary
A communication apparatus, when it perform data communication using a master base station and a secondary base station, stops communication with the secondary base station, confirms with a user whether or not the data communication is to continue in a case where communication with the secondary base station is stopped, and in a case where it was confirmed that the data communication is not continue, stops communication with the master base station.
