Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the transmitter is periodically turned on during low-power idle mode to maintain receiver states, then the transition time to active mode is reduced, but the power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of the refresh period duration based on receiver characteristics. The system transitions from a fixed refresh period to a variable one, where the duration is customized according to the specific receiver's needs, allowing optimization between power savings and transition time for each receiver scenario.
Solution Approach 2:
The patent changes the parameter of refresh period duration from a fixed value to a variable value that can be customized based on receiver characteristics. This parameter change enables the system to adapt the balance between power consumption and transition time according to specific operational requirements and receiver capabilities.
2Reliability
If the transmitter is frequently turned on to maintain accurate filter adaptation and timing lock, then the receiver performance is improved, but the power savings are reduced
Solution Approach 1:
The patent customizes the refresh period duration parameter based on receiver characteristics such as filter adaptation requirements and timing lock needs. This allows the system to optimize the frequency of transmitter activation to match the specific performance requirements of each receiver, achieving better receiver performance only when necessary.
Solution Approach 2:
The system dynamically adjusts the refresh period based on the specific receiver's performance requirements. Receivers with higher performance needs receive more frequent refreshes, while those with lower needs receive less frequent refreshes, optimizing the balance between reliability and power consumption for each individual receiver scenario.
3Use of energy by moving object
If the transmitter is turned off for long quiet intervals to maximize power savings, then the power consumption is reduced, but the transition time to active mode increases
Solution Approach 1:
The patent implements variable refresh period durations that can be customized based on receiver characteristics. This allows the system to adjust the quiet interval length dynamically, preventing excessively long intervals that would cause delayed transitions while still maximizing power savings when appropriate.
Solution Approach 2:
The system makes the refresh period dynamic rather than fixed, allowing adaptation of the quiet interval duration based on specific operational contexts and receiver needs. This dynamic approach prevents the transmitter from being off too long in scenarios where quick transition is needed.
4Device complexity
If fixed refresh periods are used in low-power idle mode, then the system complexity is reduced, but the adaptability to different receiver requirements is limited
Solution Approach 1:
The patent transforms the static refresh period into a dynamic, customizable parameter that can be adapted to different receiver requirements. This adds flexibility to accommodate various receiver architectures and characteristics while maintaining reasonable system complexity through structured customization options.
Solution Approach 2:
The system introduces customizable parameters for refresh period duration that can be adjusted based on receiver characteristics. This parameter customization enables adaptation to different receiver requirements without fundamentally complicating the system architecture.

AI summary
Low-power idle mode for network transceivers. In one aspect, a method for reducing power consumption of a transceiver connected to a communication network includes entering a low-power idle mode, and in this mode, repeatedly turning off a transmitter of the transceiver and turning on the transmitter according to a pattern, where the pattern has been customized based on characteristics of the receiver. Turning off the transmitter conserves power consumed by the transceiver.
