Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biological signal averaging processes face inefficiencies in noise removal, often requiring excessive or insufficient summation, leading to prolonged testing times and unreliable results due to the difficulty in grasping noise level reduction.
Innovation Solution
A biological signal averaging processing device that continuously acquires and processes biological signals, employing summing-averaging processing with a noise level detection unit to remove random noise, and a display unit to show noise levels chronologically, allowing for efficient termination of tests when noise levels exceed thresholds, thereby optimizing processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If summing-averaging processing is performed for a fixed predetermined number of times, then the processing can be completed with simple control, but the summation is likely excessive or deficient leading to inefficient processing
Solution Approach 1:
The patent implements feedback by continuously monitoring noise levels during the summing-averaging process and using this information to dynamically adjust the number of summations. The control unit receives noise level information and modifies the summation count accordingly, creating a closed-loop system that adapts to real-time signal conditions rather than following a fixed predetermined count.
Solution Approach 2:
The patent transitions from static predetermined summation counts to dynamic summation numbers that change based on noise level conditions. The system automatically adjusts the number of summations required based on real-time noise monitoring, making the processing duration flexible and adaptive rather than fixed, thereby optimizing efficiency for each specific signal condition.
2Reliability
If the test is continued for a long duration to reduce noise level, then the signal quality improves, but the testing time increases and patient bearing is reduced
Solution Approach 1:
The system uses continuous noise level monitoring as feedback to determine when sufficient signal quality has been achieved. The control unit monitors noise levels in real-time and can terminate the test early when the noise level drops below a predetermined threshold, avoiding unnecessary prolonged testing while ensuring adequate signal quality through evidence-based decision making.
Solution Approach 2:
The system performs preliminary noise level assessment during the early stages of summing-averaging processing to predict whether the predetermined number of summations will be sufficient. This preliminary monitoring allows the system to make informed decisions about test duration before completing the full predetermined sequence, preventing both premature termination and excessive testing.
3Productivity
If the number of summation is determined in advance, then the processing flow is simple, but the summation is likely excessive or deficient making efficient processing difficult
Solution Approach 1:
The patent introduces feedback mechanisms where noise level information is continuously monitored and fed back to the control unit. This feedback loop enables the system to automatically adjust the number of summations based on actual noise conditions, transforming a simple fixed procedure into an adaptive system that maintains operational simplicity while significantly improving processing efficiency through automated decision making.

AI summary
The biological signal averaging processing device includes a waveform input unit for continuously obtaining a biological signal in which analogous waves appear repeatedly, a summing-averaging processing unit which sums the biological signal obtained from the waveform input unit each time a predetermined time period lapses after a desired start time point to obtain an average wave, a noise level detection part which detects a noise level of random noise contained in the biological signal obtained from the waveform input unit each time the predetermined time period lapses after the desired start time point, a display part for displaying information, and a display control part for displaying the information on the screen of the display part. The display control part displays the noise levels detected by the noise level detection part on the screen of the display part in a chronological manner in association with the respective predetermined time periods.
