Solution Overview
Problem
Existing biosignal monitoring devices face challenges in efficiently transmitting and receiving biosignals while maintaining super-light and super-small characteristics, which are essential for user convenience in ubiquitous healthcare applications.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire biosignal is transmitted, then the signal quality and completeness are maintained, but the data transmission volume and power consumption increase
Solution Approach 1:
The patent extracts only the essential feature points (peaks and valleys) from the complete biosignal waveform for transmission. The parsing unit identifies and extracts these critical points, transmitting only their position and amplitude information rather than the entire signal, thereby reducing power consumption while maintaining diagnostic value.
Solution Approach 2:
The receiver reconstructs the complete biosignal waveform by copying and interpolating between the transmitted feature points. This creates a simplified representation that preserves the essential characteristics of the original signal for monitoring purposes.
2Loss of information
If the entire biosignal is transmitted, then complete signal information is preserved, but the data transmission volume increases
Solution Approach 1:
The system extracts only the critical feature points (peaks and valleys) from the biosignal for transmission. These extracted points contain the essential diagnostic information while representing a minimal subset of the complete signal data, thereby reducing transmission volume without significant information loss.
Solution Approach 2:
The patent transmits a partial representation of the biosignal (only feature points) rather than the complete signal. This partial action is sufficient for monitoring purposes and significantly reduces the data quantity that needs to be transmitted.
3Weight of moving object
If wearable devices are made super-light and super-small, then user convenience is improved, but the battery capacity and processing power are limited
Solution Approach 1:
The transmitter extracts only essential feature points from the biosignal, dramatically reducing the data processing and transmission requirements. This allows the use of smaller, lower-power components and reduces battery consumption, enabling super-light and super-small wearable device design.
Solution Approach 2:
The patent changes the parameter representation from continuous analog signal to discrete feature point coordinates. This parameter transformation reduces the computational burden and power requirements, making it feasible to implement in resource-constrained wearable devices.
