Built-in bra wearing breast pump Freestyle. When designing the product's breast cup, the product design team gave full play to their innovative wisdom, maximizing performance while streamlining components, creating a lightweight and ergonomic design for nursing mothers.

As a global leader in breast milk products, the company plans to introduce a new breast pump that can be hidden in the bra, so that busy mothers can free their hands and maintain an active lifestyle.

Faced with the wearable breast pump launched by existing competitors in the market, the product design team needed to develop a more user-friendly and efficient product to establish a significant competitive advantage over competitors.

Through in-depth user research covering multiple populations, the design team gained insight into one of the most critical issues: the cumbersome and time-consuming cleaning process of existing breast cups.

Competition analysis shows that the existing breast cups of similar products in the market usually consist of 5-7 parts, and mothers need to disassemble these parts many times a day for cleaning, drying and reassembly.

Based on this insight, streamlining the number of breast cup parts became the core design goal of the new product.

What is remarkable is that the number of parts of the optimized design of the breast cup is reduced to only 3 pieces, which highly integrates its necessary 9 key functions, which is the most critical design result of this project.

This innovation brings significant convenience and ease of use value to nursing mothers.

In addition to the functional integration challenge of "replacing more with less", the breast cup also needs to meet high standard performance requirements in vacuum negative pressure control, overflow prevention and backflow prevention. The product design team goes through multiple rounds of design refinement and rigorous testing of prototypes, and finally iterates out the ideal solution.

It is also crucial to construct the perfect ergonomic shape design for the breast cup.

The team guides the development of ergonomic morphology by analyzing anthropometric data and geometric characteristics of lactating women.

The team made several potential cup-shaped prototypes for further user trials to test their performance when worn. The test allowed the team to finally refine the cup shape into an "avocado" curve shape, effectively reducing the pressure on the chest caused by breast milk filling into the cup during breast suction.

The product design team manages the whole process of product design, development and direct production, and participates in material selection, mold coordination, injection molding testing and final packaging protection design suggestions.

The breast cup is made of medical grade PP (polypropylene) material, which not only meets the certification requirements of FDA medical devices for materials, but also its high temperature resistance allows users to safely disinfect, with soft touch and economical and practical.

In order to ensure the production of streamlined components, the breast cup shield adopts an advanced "two-shot injection molding" process, allowing the PP component to be molded in two stages, and the innovative mold structure of "slider nested slider" allows single action to realize double-sided molding. This process not only reduces the number of components, but also does not sacrifice the efficiency of breast suction.

In response to the sealing challenges posed by the organic curve shape of the breast cup, the team successfully achieved the sealing requirements by overmolding TPE (thermoplastic elastomer) in the sealing area of the part.

Freestyle breast pump has won iF and red dot design awards. The jury particularly praised: "The design is well-considered and accurately focused on user needs".
