Rotating Mammography Pressing Pad for Pain Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mammography devices cause discomfort and pain during the pressing process, which can lead to inaccurate X-ray images due to subject movement and increased exposure from repeated imaging.
Innovation Solution
The mammography device features a support system where the pressing pad and support part are configured to rotate from an inclined position to a parallel position, with an elastic member and stopper limiting the angle, allowing the pressing force to be concentrated on areas with less pain, thereby minimizing discomfort and improving image accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the pressing pad applies direct pressure to the breast to separate lumps from mammary tissue, then the X-ray image quality is improved, but the subject experiences pain and discomfort
Solution Approach 1:
The pressing pad is designed to rotate from an inclined position to a parallel position during the pressing operation. This dynamic adjustment allows the pressing force to be applied at different angles, concentrating pressure on areas with less sensitive tissue while reducing pressure on painful areas, thus improving image quality while minimizing pain
Solution Approach 2:
The pressing pad changes its angular orientation parameter from inclined to parallel during the pressing process. This parameter change allows the system to adapt the pressing force distribution, concentrating pressure on less painful areas while maintaining sufficient pressure for image quality, thereby resolving the contradiction between image quality and pain reduction
2Measurement precision
If the pressing pad maintains constant pressure to ensure image quality, then the X-ray photographing accuracy is improved, but the subject moves due to pain causing inaccurate images
Solution Approach 1:
The pressing pad rotates from an inclined position to a parallel position during the pressing operation. This dynamic adjustment allows the pressing force to be applied at different angles, concentrating pressure on areas with less pain while reducing pressure on painful areas, thereby minimizing subject movement and improving image accuracy
Solution Approach 2:
The system uses the rotation of the pressing pad as a feedback mechanism to adjust the pressing force distribution. By monitoring the angular position of the pressing pad, the system can adapt the pressing force to concentrate on less painful areas, reducing subject movement and improving the reliability of the X-ray image
3Measurement precision
If repeated imaging is performed to obtain accurate images, then the diagnostic accuracy is improved, but the exposure dose to the subject increases
Solution Approach 1:
The pressing pad rotates from an inclined position to a parallel position during the pressing operation. This dynamic adjustment improves the quality of the first image by concentrating pressure on less painful areas, reducing subject movement and the need for repeated imaging, thereby reducing the total exposure dose while maintaining diagnostic accuracy
