Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasound diagnostic apparatuses require manual user input for designating measurement points, leading to variability in measurement accuracy and efficiency, with potential failures in detecting targets when the designated position is significantly deviated from the actual center.
Innovation Solution
An acoustic wave diagnostic apparatus with a display unit, operation unit, user identification, measurement item designation, position designation, detection and measurement algorithm setting, and a scan range modification unit that adjusts the scan range based on user input and detection reliability, allowing for automatic detection and measurement of targets with improved accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation by user is performed to set measurement point, then measurement can be performed, but measurement time and effort increase and measurement accuracy varies due to user experience and skill level
Solution Approach 1:
The system performs preliminary actions by automatically determining the scan range based on the measurement item and storing it in association with user identification information. This pre-configured scan range is then used for subsequent measurements, eliminating the need for manual point-setting and reducing measurement time while maintaining accuracy.
Solution Approach 2:
The measurement unit performs self-service by automatically detecting the measurement target within the pre-determined scan range without requiring manual intervention for point designation. The system uses stored scan range information and detection algorithms to autonomously complete measurements, improving efficiency and reducing time loss.
2Reliability
If user designates position of measurement target manually, then measurement can be performed, but detection may fail when designated position is greatly deviated from center of measurement target
Solution Approach 1:
The system performs preliminary action by determining and storing the scan range in association with user identification information before measurement. This pre-established scan range ensures that the measurement target is always within the detection area, preventing detection failure even when user designation is inaccurate.
Solution Approach 2:
The system provides beforehand cushioning by creating a buffer zone through the pre-determined scan range that accommodates variations in user designation accuracy. The scan range is set to ensure the measurement target is captured regardless of minor position deviations, cushioning against detection failures.
3Productivity
If automatic detection is implemented without user input, then measurement speed increases, but the system cannot adapt to different users with varying designation accuracy
Solution Approach 1:
The system performs preliminary action by determining the scan range based on user identification information before measurement. This allows the system to adapt to different users' characteristics and designation patterns while maintaining automatic measurement speed, achieving both productivity improvement and adaptability.
Solution Approach 2:
The system implements dynamics by making the scan range adjustable and adaptable based on user identification information. The scan range can be modified according to each user's designation accuracy and preferences, allowing the system to adapt to different users while maintaining automated measurement functionality.
