Network Transmitter Dynamic Voltage Regulation for Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network transmitting apparatuses face excessive power consumption due to the need to maintain maximum voltage levels for varying network transmission speeds, such as 10 Mbps, 100 Mbps, and 1000 Mbps, which is inefficient and wasteful.
Innovation Solution
A network transmitting apparatus comprising a chip with a detecting and controlling unit, a transformer, and a power regulating unit that dynamically adjusts voltages based on detected network transmission speed, signal-to-noise ratio, and internal chip delay to optimize power usage by generating regulated voltages for the transformer, analog circuit, and digital circuit.

Engineering Contradiction Analysis
1Reliability
If the network transmitting apparatus maintains maximum voltage level (±2.5V) for all transmission speeds, then normal operation at all speeds (10Mbps, 100Mbps, 1000Mbps) is ensured, but power consumption becomes excessive
Solution Approach 1:
The patent implements dynamic voltage regulation by adjusting the voltage level according to the actual network transmission speed. The power regulating unit receives control signals indicating the transmission speed and dynamically switches between different voltage levels (±2.5V for 10Mbps, ±1V for 100Mbps/1000Mbps), making the voltage adaptive rather than static. This resolves the contradiction by maintaining reliability when needed while reducing power consumption when full voltage is not required.
Solution Approach 2:
The patent changes the voltage parameter based on transmission speed requirements. By detecting the transmission speed and adjusting the voltage level accordingly, the system transitions from a fixed parameter (always ±2.5V) to a variable parameter that optimizes both reliability and power consumption. This parameter change allows the apparatus to operate reliably at each speed while minimizing excessive power usage.
2Use of energy by moving object
If the network transmitting apparatus uses voltage regulation to save power, then power consumption is reduced, but device complexity increases due to additional control circuits
Solution Approach 1:
The detecting and controlling unit in the chip performs multiple functions: it detects transmission speed, generates control signals for voltage regulation, and maintains normal chip operation. By making this unit multi-functional, the patent avoids adding separate dedicated circuits for each function, thereby reducing overall device complexity while still achieving power savings through voltage regulation.
Solution Approach 2:
The patent merges the voltage regulation control functionality into the existing detecting and controlling unit of the chip. Instead of adding a separate complex control system, the regulation logic is integrated with the existing control unit that already manages transmission operations. This merging approach achieves power savings while minimizing the increase in device complexity.
