Dynamic Pulse Interval Display Resolution for Biological Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biological information measurement devices struggle to provide adequate display resolution for pulse intervals, leading to difficulties in visually recognizing fluctuations, especially for individuals with high pulse rates.
Innovation Solution
A biological information measurement device equipped with pulse acquisition, interval calculation, and display means, along with a display resolution determination unit that optimizes the minimum and maximum values of the pulse interval displayed, using information on consecutive pulse intervals to ensure appropriate resolution regardless of individual differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the maximum value of the level indicator is set to accommodate the maximum pulse interval (e.g., 1.5 seconds), then all users can see their pulse intervals displayed, but the display resolution becomes low for users with small pulse intervals (high pulse rates)
Solution Approach 1:
The level indicator dynamically adjusts its scale range based on the user's actual pulse interval characteristics. The display resolution determination unit calculates the minimum and maximum pulse intervals from acquired pulse data, then sets the level indicator's display range accordingly. This dynamic adaptation allows the display to optimize resolution for each user's specific pulse rate while still accommodating the full range of pulse intervals.
Solution Approach 2:
The system changes the display parameters (minimum and maximum values) of the level indicator based on the measured pulse interval data. Instead of using fixed display ranges, the system adjusts the parameter settings of the level indicator to match the user's pulse characteristics, thereby improving display resolution without sacrificing adaptability.
2Device complexity
If a fixed level indicator range is used for all users, then the device structure remains simple, but users with high pulse rates cannot easily recognize pulse interval fluctuations
Solution Approach 1:
The display system automatically determines the appropriate display range for each user without requiring manual configuration. The display resolution determination unit autonomously analyzes the pulse interval data and adjusts the level indicator parameters accordingly, making the system self-adapting while maintaining structural simplicity.
Solution Approach 2:
The level indicator transitions from a static fixed-range display to a dynamic adaptive display that automatically adjusts its scale based on the user's pulse characteristics. This dynamic behavior improves fluctuation recognition accuracy while adding minimal complexity to the overall system.
