Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bladder volume measurement methods rely heavily on user experience and subjective feeling to position a detector, leading to difficulty in accurately determining the next target moving direction, which prolongs the positioning time and reduces measurement efficiency.
Innovation Solution
A bladder volume measuring method and system that utilizes a detector capable of rotating around a defined direction, acquiring initial sectional images at preset angles, confirming the bladder's position, and generating prompt information to guide the user on the next moving direction, thereby improving positioning accuracy and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user manually positions the detector based on experience and subjective feeling, then the method is simple to operate, but the positioning accuracy is poor and positioning time is long
Solution Approach 1:
The system implements real-time feedback by acquiring initial sectional images during detector rotation, automatically identifying bladder position and orientation, and providing prompt information (arrows, text) to guide the user's next movement direction. This closed-loop feedback mechanism enables the user to quickly and accurately position the detector without relying on subjective experience, thereby improving positioning accuracy while reducing positioning time.
Solution Approach 2:
The measuring device performs automatic bladder position detection and analysis without requiring user expertise. The system autonomously processes the sectional images, determines bladder orientation, and generates movement guidance, allowing the device to serve itself in the positioning task and reducing dependence on operator skill.
2Productivity
If a user manually positions the detector without guidance, then the device operation is straightforward, but the measurement efficiency is low
Solution Approach 1:
The system provides real-time feedback through prompt information that clearly indicates the next target moving direction. This guidance reduces the cognitive load on the user and eliminates trial-and-error positioning, thereby improving measurement efficiency without significantly complicating the operational process.
Solution Approach 2:
The system performs preliminary analysis of the initial sectional images to determine bladder position and orientation before the user makes the next movement. By preparing the guidance information in advance, the system enables the user to proceed directly with the recommended action, improving workflow efficiency.
3Measurement precision
If the system acquires multiple initial sectional images at preset angles, then the bladder position determination accuracy is improved, but the data processing complexity increases
Solution Approach 1:
The system segments the bladder positioning task into multiple discrete sectional image acquisitions at preset rotation angles. By dividing the full rotation into discrete angular steps (e.g., every 15° or 30°), the system comprehensively captures bladder position information from multiple viewpoints, improving determination accuracy while keeping each individual measurement simple and manageable.

AI summary
A bladder volume measuring method is disclosed. The measuring method is applied to a measuring device, the measuring device includes a detector for acquiring a sectional image of a bladder and rotatable around a first direction, and the first direction is a direction of a connecting line between the detector and a measured position. The measuring method includes: when the detector rotates around the first direction, acquiring a corresponding initial sectional image every time the detector rotates by a first preset angle; confirming a current position of the bladder according to all the initial sectional images, and generating and displaying corresponding prompt information; the prompt information being used for prompting a user to move the detector; and after the detector moves, when the detector rotates around the first direction again, acquiring a corresponding current sectional image at an interval of a second preset angle to calculate the bladder volume.
