Solution Overview
Problem
In electronic devices supporting dual connectivity, managing heat generation is challenging due to differences in heat production between LTE and NR networks, necessitating an efficient method to determine which network to release from connection to minimize heat.
Innovation Solution
The electronic device includes first and second communication circuits for LTE and NR networks, respectively, and a processor that determines which network to release based on conditions such as surface heating temperature, number of layers received, and transmission power, then transmits a signal to release the connection and performs subsequent operations based on the response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the connection with the 5G network is released to suppress heat generation, then heat generation is reduced, but data transmission efficiency may deteriorate
Solution Approach 1:
The patent changes the parameter of network selection by introducing multiple decision factors (temperature, layer count, transmission power) rather than simply releasing 5G connection upon temperature threshold exceedance. This allows dynamic adjustment of network parameters to balance heat suppression with data transmission efficiency.
Solution Approach 2:
The patent implements dynamic network connection management where the system continuously monitors temperature, layer count, and transmission power to dynamically decide whether to release LTE or NR connection. This dynamic approach ensures optimal balance between heat generation suppression and data transmission efficiency under varying conditions.
2Temperature
If the connection with the LTE network is released to suppress heat generation, then heat generation is reduced, but network coverage reliability may deteriorate
Solution Approach 1:
The patent incorporates feedback mechanisms by monitoring layer count and transmission power in addition to temperature. The system uses this feedback to intelligently determine which connection to release, ensuring that network coverage reliability is maintained by avoiding release of the only available network type.
Solution Approach 2:
The patent changes the decision parameter from simple temperature threshold to a composite decision framework considering temperature, layer count, and transmission power. This allows the system to maintain reliability by only releasing connections when alternative network coverage is available.
3Productivity
If dual connectivity is maintained to improve data transmission efficiency, then data transmission efficiency is improved, but heat generation increases
Solution Approach 1:
The patent implements dynamic connection management where dual connectivity is maintained or released based on real-time monitoring of temperature, layer count, and transmission power. This dynamic adjustment allows the system to optimize the balance between data transmission efficiency and heat generation control.
Solution Approach 2:
The patent changes from static dual connectivity to dynamic connection management by introducing multiple decision parameters. The system can transition between single and dual connectivity modes based on current operating conditions, optimizing both efficiency and thermal performance.
4Temperature
If network connection release decision is based solely on temperature threshold, then heat generation is suppressed, but current consumption management becomes inefficient
Solution Approach 1:
The patent changes the decision parameter from temperature-only to a composite framework including temperature, layer count, and transmission power. This allows for more efficient current consumption management by considering the actual data transmission requirements and network capabilities.
Solution Approach 2:
The patent implements dynamic current consumption management by continuously monitoring multiple parameters and adjusting network connections accordingly. The system optimizes current consumption by releasing connections based on comprehensive conditions rather than fixed temperature thresholds.
