Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a first communication scheme is used to provide high throughput and low latency, then data transfer performance is improved, but current consumption and heat generation increase
Solution Approach 1:
The patent implements dynamic communication scheme selection based on real-time temperature monitoring. The system switches between first and second communication schemes according to thermal conditions, allowing the communication mode to adapt dynamically rather than remaining fixed. This resolves the contradiction by enabling high performance when needed and energy saving when thermal constraints exist.
Solution Approach 2:
The patent changes the operational parameters of the communication module by switching between different communication schemes (first and second schemes) based on temperature thresholds. This parameter change allows the system to adjust its performance characteristics and power consumption levels to match thermal constraints while maintaining service quality.
2Productivity
If a first communication scheme is used to provide high throughput and low latency, then data transfer performance is improved, but heat generation increases
Solution Approach 1:
The system dynamically switches communication schemes based on real-time temperature feedback from the temperature sensor. When temperature exceeds the threshold, the system transitions to a lower-performance but cooler second communication scheme, thereby controlling heat generation while maintaining performance when thermal conditions permit.
Solution Approach 2:
The patent implements a feedback mechanism where the temperature sensor continuously monitors the communication module's thermal state and feeds this information back to the processor. This feedback loop enables the system to adjust communication parameters in response to actual thermal conditions, preventing excessive heat generation while maintaining performance.
3Adaptability or versatility
If multiple communication schemes are supported to meet different QoS requirements, then adaptability is improved, but device complexity increases
Solution Approach 1:
The communication module is designed with multi-functionality to support both first and second communication schemes within a single integrated component. This universal design allows the device to meet different QoS requirements (high throughput, low latency, or energy saving) without requiring separate communication devices, thereby managing complexity while maintaining adaptability.
Solution Approach 2:
The system pre-configures multiple communication schemes and their corresponding performance characteristics before runtime. The processor and temperature sensor are pre-positioned to monitor and switch between schemes as needed, eliminating the need for complex real-time decision-making architecture and reducing overall system complexity.

AI summary
A method and an electronic device are provided for implementing power and heat generation control by efficiently using a resource. The electronic device includes a communication module supporting a first communication scheme and a second communication scheme; a temperature sensor; and a processor configured to execute an application by using the first communication scheme, measure a temperature value by using the temperature sensor, identify a policy related to the executed application when the measured temperature value is higher than a preconfigured temperature value, determine whether the identified policy satisfies a quality of service (QoS) required by the application, and execute the identified policy upon determining that the identified policy satisfies the QoS required by the application. The policy uses the second communication scheme.
