1Speed

If mmWave bands are used for 5G communication to achieve high data rate, then communication speed is improved, but device temperature increases causing overheat

Engineering Contradiction:

Core Design Contradiction:

SpeedVSTemperature

Solution Approach 1:

The patent dynamically adjusts communication parameters (bandwidth, MIMO rank count) based on real-time temperature monitoring. When overheat is detected, the device transitions from high-performance mode to thermal management mode, making the system adaptable to changing thermal conditions while maintaining communication functionality.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes communication parameters (reducing maximum bandwidth and MIMO rank count) in response to temperature conditions. This parameter adjustment allows the system to reduce power consumption and heat generation while maintaining essential communication capabilities during overheat scenarios.

Inventive Principle:

Principle #35Parameter changes

2Temperature

If communication parameters are reduced to manage heat, then device temperature is controlled, but communication performance deteriorates

Engineering Contradiction:

Core Design Contradiction:

TemperatureVSProductivity

Solution Approach 1:

The patent applies partial action by reducing only specific communication parameters (bandwidth, MIMO rank) rather than completely shutting down communication. This selective reduction manages temperature while preserving essential communication functionality, achieving thermal control without total performance loss.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The patent implements a feedback mechanism where temperature is continuously monitored and communication parameters are adjusted based on thermal conditions. This closed-loop control allows the system to respond to temperature changes dynamically, balancing thermal management with communication performance requirements.

Inventive Principle:

Principle #23Feedback
