Data Transmission Bias Circuit for Current Recycling and Heat Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data transmission systems consume power and generate heat due to the use of a terminal bias voltage source and bias resistors, leading to potential damage and inefficiency.
Innovation Solution
Recycle current by coupling the bias resistor to a load at a terminal bias voltage, eliminating the need for a separate voltage source and allowing current to be reused at the load side, thereby reducing power consumption and heat generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal bias voltage source and bias resistor are used to bias the transmission line, then data transmission is facilitated, but power consumption increases and heat is generated
Solution Approach 1:
The patent recovers the bias current that would otherwise be discarded by the terminal bias voltage source. By coupling the bias resistor to the data transmission line and allowing current to flow through the line to a load, the system recovers energy that would have been wasted, converting it into useful current at the load side while maintaining the necessary bias for data transmission
Solution Approach 2:
The data transmission line itself serves dual purposes: it transmits data and simultaneously serves as a current path for biasing the transmission line. The line 'services itself' by carrying both data signals and bias current, eliminating the need for a separate terminal bias voltage source and reducing overall power consumption
2Reliability
If a terminal bias voltage source and bias resistor are used to bias the transmission line, then data transmission is facilitated, but heat accumulation increases causing potential damage
Solution Approach 1:
The patent recovers the bias current that would otherwise be discarded by the terminal bias voltage source. By coupling the bias resistor to the data transmission line and allowing current to flow through the line to a load, the system recovers energy that would have been wasted, converting it into useful current at the load side while maintaining the necessary bias for data transmission
Solution Approach 2:
The patent converts the harmful effect of bias current (which generates heat when dissipated) into a beneficial effect by routing it through the data transmission line to power a load. The current that would have been wasted as heat is now utilized to drive the load, transforming a harmful thermal effect into a useful power source
