Detachable Pumping Bra Cups With Avoidance Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional breastfeeding bras require complete detachment for using a breast pump, causing inconvenience and potentially affecting the efficiency and stability of milk extraction.
Innovation Solution
A bra design featuring detachable cups and strategically positioned avoidance grooves for breast pumps, allowing for quick and stable attachment and detachment of the pump without fully removing the bra.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional breastfeeding bra requires the whole bra to be pulled out when the breast pump is used, then the breast pump can be fully exposed for use, but it causes inconvenience in use of the breast pump and increases the time required for pump operation
Solution Approach 1:
The bra cup is divided into two detachable parts: a first cup body portion and a second cup body portion. The first portion remains attached to the bra while the second portion can be detached to expose the breast pump insertion area. This segmentation allows the pump to be accessed without removing the entire bra, resolving the contradiction between full exposure and convenience/time.
Solution Approach 2:
The second cup body portion is extracted as a detachable component that can be separated from the first cup body portion. This extraction creates a localized opening for breast pump insertion without requiring removal of the entire bra structure, thereby maintaining support while enabling pump access.
2Measurement precision
If the breast pump is inserted into the avoidance groove, then the pump fits accurately on the chest, but the groove structure adds complexity to the bra design
Solution Approach 1:
The avoidance groove is designed with a flexible inner wall that can dynamically adapt to the breast pump's insertion. The groove structure allows for elastic deformation to accommodate the pump while maintaining structural integrity, achieving accurate fitting without excessive structural complexity.
Solution Approach 2:
The inner wall of the avoidance groove is constructed from flexible material that can deform to accommodate the breast pump. This flexible shell approach provides accurate positioning and secure fit while keeping the overall structure relatively simple and integrated into the cup fabric.

AI summary
An adjustable bra includes a connecting strap, a first shoulder strap, a second shoulder strap, and a cup. One side of the cup is connected to the connecting strap, and the opposite side is detachably connectable to the first and second shoulder straps. A first avoidance groove for inserting a breast pump is defined on an inner side of the cup at a position corresponding to the left chest, and a second avoidance groove for inserting the breast pump is defined on an inner side of the cup at a position corresponding to the right chest. The detachable connections provide a top opening for inserting or removing the pump.
