Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network devices with small form factors face thermal management challenges due to inadequate power management, which can affect performance and connectivity, and existing power management methods like removing radio chains do not consider network performance factors effectively.
Innovation Solution
A network controller device models network performance using information from network devices and links to optimize power management by altering operations such as reducing radio chains, duty cycles, or transmission power, and steers connections to maintain network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If power is managed by removing one or more radio chains of a network device, then thermal parameters are reduced, but network performance and connectivity are degraded
Solution Approach 1:
The patent dynamically adjusts operational parameters such as duty cycle and transmission power of radio chains instead of simply removing them. The network controller monitors thermal parameters and network performance, then modifies these parameters to achieve thermal management while maintaining connectivity and performance requirements.
Solution Approach 2:
The system implements dynamic thermal management where the network controller continuously monitors thermal parameters and network conditions, then adapts radio chain operations in real-time. This allows the system to respond to changing thermal and performance requirements rather than using static configurations.
2Reliability
If network devices operate at high power to maintain network performance, then connectivity is improved, but thermal parameters increase and may damage internal components
Solution Approach 1:
The network controller implements a feedback mechanism that continuously monitors thermal parameters of network devices and uses this information to adjust operational parameters. When thermal parameters exceed thresholds, the controller reduces power consumption by adjusting duty cycles or transmission power, ensuring thermal management while maintaining performance.
Solution Approach 2:
Instead of fixed power operation, the system dynamically changes operational parameters including duty cycle and transmission power based on monitored thermal conditions. This allows the network to maintain connectivity while adapting power consumption to thermal constraints.
3Volume of moving object
If the form factor of network devices is reduced, then device size is minimized, but thermal dissipation capability is impaired
Solution Approach 1:
The network controller provides self-service thermal management by automatically monitoring thermal parameters of small-form-factor devices and adjusting operational parameters to maintain safe operating temperatures. This allows compact devices to operate reliably without requiring larger physical structures for passive cooling.
Solution Approach 2:
The system uses dynamic parameter adjustment to compensate for the limited thermal dissipation capacity of small devices. By continuously adapting duty cycles and transmission power based on thermal feedback, the system enables reliable operation of compact network devices that would otherwise overheat.
4Use of energy by moving object
If radio chains are removed for power management, then power consumption is reduced, but network performance optimization is insufficient as network conditions are not considered
Solution Approach 1:
The network controller uses feedback from network performance parameters and thermal conditions to intelligently adjust power consumption. Rather than simply removing radio chains, the system monitors network conditions and dynamically modifies operational parameters to optimize both power efficiency and network performance based on actual requirements.
Solution Approach 2:
The system transitions from static radio chain configuration to dynamic parameter adjustment based on real-time network conditions. This allows flexible optimization of power consumption while maintaining network performance, adapting to changing traffic patterns and thermal conditions rather than using fixed configurations.

AI summary
A network controller device can be used to manage a network performance of a network by utilizing network parameters associated with the entirety of the network as well as network device parameters associated with one or more network devices in the network. As the network controller device has information about the entirety of the network as well as individual network devices, the network controller device can model a predicted network performance so as to identify one or more network devices. The identified one or more network devices can be sent a notification so as to modify, alter or change one or more operations associated with the identifier one or more network devices.
