Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If energy saving functions are activated in radio units, then energy consumption is reduced, but network performance and reliability may deteriorate
Solution Approach 1:
The patent implements dynamic energy saving strategies where the network device adjusts its operational state based on real-time conditions. The management device receives performance information from the network device and dynamically configures energy saving functions, transitioning between active and energy-saving states according to network load and performance requirements, thus resolving the contradiction between energy consumption and network performance
Solution Approach 2:
The patent changes operational parameters such as power amplifier output power, antenna gain, and processing frequency based on network conditions. By adjusting these parameters dynamically, the system can reduce energy consumption during low-load periods while maintaining adequate performance during high-load periods, effectively balancing the contradiction
2Speed
If components like power amplifiers are kept active during low load periods, then network responsiveness is maintained, but energy consumption increases
Solution Approach 1:
The patent implements periodic monitoring of network load and performance metrics, with the management device receiving information at scheduled intervals and adjusting energy saving configurations accordingly. This periodic action allows the system to maintain responsiveness during high-load periods while activating energy saving modes during low-load periods, resolving the contradiction between speed and energy consumption
3Device complexity
If energy saving functions are managed autonomously by the network device, then operational complexity is reduced, but adaptability to varying network conditions decreases
Solution Approach 1:
The patent introduces a management device as an intermediary between the network device and the energy saving control logic. The management device receives performance information from the network device, processes this information according to energy saving policies, and sends configuration commands back to the network device. This intermediary approach maintains low operational complexity at the network device while achieving high adaptability through centralized intelligence
Solution Approach 2:
The patent implements a feedback loop where the management device continuously receives performance information from the network device and uses this feedback to adjust energy saving configurations. This closed-loop control ensures the system adapts to varying network conditions while keeping the network device itself relatively simple, as the complex decision-making logic resides in the management device
