Breast Fixation Bra Cutout Structure for Accurate Radiation Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing breast fixation bras for radiation treatment do not adequately maintain the position and shape of the breast undergoing treatment, fail to separate the non-treated breast effectively, and may interfere with radiation delivery due to their design.
Innovation Solution
A breast fixation bra with a pair of breast cover parts featuring cutout portions and support members, including lateral, vertical, and diagonal support structures, designed to maintain the treated breast's position and shape while separating the untreated breast, using air-equivalent materials to minimize radiation interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional breast fixation bra is used, then the breast is covered and supported, but the position and shape of the breast during radiation treatment cannot be maintained accurately and the non-treated breast cannot be separated effectively
Solution Approach 1:
The breast cover part is divided into multiple segments including a first breast cover part with a cutout portion and a second breast cover part. This segmentation allows the treated breast to protrude through the cutout while the other breast is separated by the second cover part, enabling precise positioning and shape maintenance without requiring a completely complex new structure
Solution Approach 2:
The bra structure is made asymmetric with different properties for each breast cover part. The first breast cover part has a cutout portion providing a specific shape for the treated breast, while the second breast cover part provides separation for the non-treated breast. This local differentiation enables each part to fulfill its specific function for accurate radiation treatment positioning
2Measurement precision
If the breast is fixed tightly for position maintenance, then radiation delivery accuracy improves, but radiation exposure to the non-treated breast increases
Solution Approach 1:
The breast cover part is segmented into a first breast cover part with a cutout portion and a second breast cover part. This segmentation physically separates the treated breast (which protrudes through the cutout) from the non-treated breast, allowing tight fixation of the treated breast for accurate radiation delivery while simultaneously providing separation to minimize radiation exposure to the non-treated breast
Solution Approach 2:
The cutout portion extracts or removes material from the first breast cover part to create an opening. This extraction allows the treated breast to protrude through the cutout, enabling precise positioning and tight fixation for accurate radiation delivery, while the remaining structure of the second breast cover part continues to provide separation and protection for the non-treated breast

AI summary
Disclosed herein is a breast fixation bra for radiation treatment having at least one cutout portion, the breast fixation bra including: a body part provided to cover the breasts in the lateral direction; a pair of breast cover parts provided to protrude on both sides of the central portion of the body part in order to correspond to the shapes of the breasts; at least one cutout portion provided in a shape in which at least a portion is cut out from a corresponding one of the breast cover parts; and at least one lateral support member provided across at least one of the breast cover parts with one end thereof coupled to the central portion of the body part and the other end coupled to a side portion or the rear support member of the body part, and configured to support a breast accommodated in the cutout portion.
