Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrosurgical instruments and generators have complex circuits that limit the functionality of data transmission and reception, making it difficult to efficiently communicate multiple data streams.
Innovation Solution
A system and method that encode multiple data streams into a single pulsed transmission signal, where the frequency represents one data stream and the pulse width represents another, allowing for decoding across an isolation barrier using a signal processor with a pulse counter and pulse width converter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional circuits and processes are used for transmitting data, then data transmission can be achieved, but device complexity increases and functionality is limited
Solution Approach 1:
The patent combines multiple data streams into a single transmitted signal by encoding them as frequency and pulse width modulations on one carrier wave. This merging approach reduces the number of separate transmission lines and circuits needed, thereby reducing overall device complexity while maintaining the ability to transmit multiple types of data simultaneously.
Solution Approach 2:
A single transmission signal serves multiple functions by carrying different data streams through different encoding methods (frequency modulation for one stream, pulse width modulation for another). This multi-functionality allows the system to transmit various types of data over the same channel without requiring separate dedicated transmission circuits for each data stream.
2Loss of information
If multiple separate data streams are transmitted, then complete data communication is achieved, but power requirements increase
Solution Approach 1:
By merging multiple data streams into a single transmitted signal through frequency and pulse width modulation, the system reduces the total power consumption compared to transmitting each data stream separately. The combined signal utilizes the same power infrastructure more efficiently, reducing redundant power usage while maintaining complete data communication through proper decoding of both modulation types.
