Bridge Module Rate Adjustment for Power Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bridge modules experience low data transmission rates and increased power consumption when exchanging data between hosts and data transmission devices due to inefficient rate matching between uplink and downlink data transmission rates.
Innovation Solution
A bridge module with a processing device that adjusts the downlink data transmission rate according to the uplink data transmission rate, using a first and second transmission unit connected to the host and data transmission device respectively, to ensure the downlink rate does not exceed the uplink rate, thereby optimizing data exchange efficiency and reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the bridge module uses a fixed high downlink data transmission rate, then the data transmission speed is improved, but the power consumption increases
Solution Approach 1:
The patent applies dynamics by making the downlink data transmission rate adjustable rather than fixed. The processing device dynamically adjusts the downlink rate based on the detected uplink rate, allowing the system to adapt transmission parameters to actual conditions. This resolves the contradiction by enabling high speed when needed while reducing power consumption when lower rates suffice.
Solution Approach 2:
The patent changes the transmission rate parameter based on detected conditions. The processing device detects the uplink data transmission rate and adjusts the downlink rate parameter accordingly, ensuring it does not exceed the uplink rate. This parameter adjustment mechanism allows the system to optimize both speed and power consumption by matching rates to actual data flow requirements.
2Productivity
If the bridge module uses asymmetric rate matching (downlink rate much higher than uplink rate), then the downlink transmission efficiency is improved, but resource wastage occurs
Solution Approach 1:
The patent implements feedback by having the processing device detect the uplink data transmission rate and use this information to adjust the downlink rate. This closed-loop feedback mechanism ensures the downlink rate is optimized based on actual uplink conditions, improving transmission efficiency while preventing resource wastage from excessive rate asymmetry.
Solution Approach 2:
The system dynamically adjusts the downlink transmission rate based on detected uplink conditions rather than using a fixed asymmetric configuration. This dynamic adaptation allows the system to achieve optimal downlink efficiency while matching rates to actual data flow, preventing resource wastage from overly aggressive rate asymmetry.
