Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If emission power is reduced to lower power consumption, then power consumption decreases, but data transmission reliability deteriorates
Solution Approach 1:
The patent implements dynamic emission power adjustment by continuously monitoring data transmission performance metrics (such as packet error rate, throughput) and adapting the emission power level in real-time. The system transitions from static power settings to dynamic control, where power is adjusted based on actual transmission conditions, thereby maintaining reliability while optimizing power consumption.
Solution Approach 2:
The patent establishes a feedback mechanism that monitors data transmission performance and uses this information to control emission power adjustments. The system measures transmission metrics, compares them against thresholds, and adjusts power accordingly - creating a closed-loop control system that balances power consumption with transmission reliability through continuous feedback.
2Reliability
If emission power is increased to ensure stable data transmission, then data transmission reliability improves, but power consumption increases
Solution Approach 1:
The patent changes the emission power parameter dynamically based on transmission performance conditions. Instead of maintaining a fixed high power level, the system adjusts the power parameter according to measured transmission metrics, using parameter change to achieve the dual goal of maintaining reliability while minimizing power consumption.
Solution Approach 2:
The patent applies partial action by adjusting emission power only when and to the extent necessary to meet transmission reliability requirements. Rather than continuously operating at maximum power, the system uses minimal necessary power adjustments to achieve stable transmission, avoiding excessive power consumption while maintaining reliability.
3Use of energy by moving object
If emission power is frequently adjusted to optimize performance, then power consumption efficiency improves, but system complexity increases
Solution Approach 1:
The patent segments the emission power adjustment process into discrete, manageable steps with predefined power levels and adjustment intervals. By dividing the continuous power control problem into segmented stages (measurement phase, evaluation phase, adjustment phase), the system reduces complexity while maintaining optimization capability.
Solution Approach 2:
The patent implements periodic emission power adjustment rather than continuous adjustment, using fixed scanning cycles and adjustment intervals. This periodic approach simplifies the control system by establishing regular measurement and adjustment rhythms, reducing computational burden and system complexity while still achieving power optimization.
4Adaptability or versatility
If emission power adjustment scanning cycle is shortened to improve responsiveness, then adaptability to changing conditions improves, but power consumption during scanning increases
Solution Approach 1:
The patent dynamically adjusts the scanning cycle length based on transmission conditions. When transmission is stable, longer scanning cycles are used to reduce scanning power consumption. When conditions change rapidly, the system shortens scanning cycles to improve adaptability. This dynamic scanning cycle adjustment resolves the contradiction between responsiveness and power consumption.

AI summary
An emission power adjusting method, a communication chip, and an electronic device are provided. The method includes: during a scanning cycle, adjusting the emission power according to a first adjusting time interval, a configured step size and an adjusting direction, performing a first type of frame data transfer, and obtaining data transmission performance data for the first type of frame data transfer; and in a case where it is determined that the data transmission performance data meets a condition for ceasing adjustment, ceasing further adjustment of the emission power, and determining an operating emission power. According to the sequential scanning mode, the operating transmission power of a wireless communication device is determined according to the changing trend of actual data transmission performance. Therefore, the optimal emission power of the wireless communication device may be determined while the wireless communication service requirement is met, thereby effectively reducing device power consumption.
