Solution Overview
Problem
Existing image acquisition devices for breast imaging face challenges in managing the deterioration of compression members, which vary in material, size, and shape, affecting their strength and longevity.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different compression members with varying materials, sizes, and shapes are used to adapt to different breast types and imaging purposes, then adaptability and imaging suitability are improved, but the strength of compression members varies causing unequal deterioration rates and reduced reliability
Solution Approach 1:
The system changes the parameter of compression force according to the type of compression member being used. The control device identifies the compression member type (which has varying strength characteristics based on material, size, and shape) and adjusts the compression force parameter accordingly, applying lower compression force to weaker members and higher compression force to stronger members, thereby resolving the contradiction between adaptability and reliability
Solution Approach 2:
The system implements feedback by identifying the compression member type and using this information to control the compression force. The control device receives information about the compression member characteristics and adjusts the compression parameters in response, creating a closed-loop control system that maintains optimal performance across different compression member types
2Manufacturing precision
If high compression force is applied to achieve good imaging quality, then image quality is improved, but compression members with relatively low strength deteriorate more quickly
Solution Approach 1:
The system dynamically changes the compression force parameter based on the identified compression member type. For compression members with relatively low strength, the system applies lower compression force to prevent excessive deterioration, while for stronger members, higher compression force can be applied to maintain image quality. This parameter adjustment resolves the contradiction between image quality and compression member lifespan
Solution Approach 2:
The system applies partial compression force rather than maximum compression force for all members. By identifying the strength characteristics of each compression member type, the system applies only the necessary compression force required for adequate imaging, avoiding excessive compression that would accelerate deterioration of weaker members while still achieving sufficient image quality

AI summary
A control device comprising at least one processor, wherein the at least one processor is configured to: acquire type information indicating a type of a compression member attached to an image acquisition device that captures a radiation image by irradiating a breast in a compressed state between an imaging table and the compression member with radiation; and set an upper limit value of a compression force applied to the breast by the compression member based on the type information.
