Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If components are added to improve bearer capability, then network device performance is improved, but power consumption is greatly increased
Solution Approach 1:
The patent implements dynamic component shutdown by controlling switches to connect or disconnect components based on traffic conditions. The radio frequency module can dynamically adjust which components (power amplifier, filter, ADC, DAC) are active or inactive, transitioning between different energy saving modes (first, second, third modes) depending on whether traffic exceeds thresholds, thereby resolving the contradiction between maintaining performance and reducing power consumption
Solution Approach 2:
The system changes operational parameters by monitoring traffic volume and comparing it against first and second thresholds. When traffic exceeds the first threshold, the system activates more components; when traffic is below the second threshold, fewer components remain active. This parameter-based control allows the system to adapt component usage to actual network conditions, optimizing the balance between bearer capability and power consumption
2Ease of manufacture
If fixed component combination is used for energy saving, then implementation is simple, but energy saving flexibility is poor
Solution Approach 1:
The patent employs dynamic control mechanisms where switches respond to real-time traffic conditions, enabling the system to transition between multiple energy saving modes. This dynamic approach provides flexibility in energy saving implementation while maintaining relatively simple control logic based on threshold comparisons, thus balancing implementation simplicity with energy saving flexibility
Solution Approach 2:
The radio frequency module is segmented into multiple independently controllable components (power amplifier, filter, ADC, DAC), each with its own switch. This segmentation allows selective shutdown of individual components based on traffic conditions, providing flexible energy saving strategies without requiring complete system shutdown or complex coordinated control of all components simultaneously

AI summary
An energy saving method and a related device are provided to implement, by dynamically shutting down some or all components in a radio frequency module including N components, a plurality of different energy saving modes of the radio frequency module so as to improve flexibility of energy saving implementation and improve an energy saving effect. The radio frequency module operates a target energy saving mode in M energy saving modes, where M is an integer greater than or equal to 2. The radio frequency module includes the N components, and when P components in the N components are shut down, the radio frequency module operates one energy saving mode in the M energy saving modes, where N is an integer greater than or equal to 2, and P is a positive integer.
