Polymer-Web Bra Cup Structure for Projection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unlined bras lack effective means to minimize breast projection and provide adequate support without using padding or heavier fabrics, leading to unsatisfactory shaping and comfort.
Innovation Solution
A bra cup design featuring an inner mesh layer with a thin polymer web made of aqueous polyurethane dispersion, comprising interconnected geometrical line segments, primarily triangles, disposed on the outer face of the mesh layer, providing support and minimizing breast projection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional padding or heavier fabrics are used in unlined bras, then breast support and projection control are improved, but weight and comfort deteriorate
Solution Approach 1:
The patent applies a thin polymer film (aqueous polyurethane dispersion) as a flexible shell structure that provides breast support and projection control without the weight of traditional padding. The film forms a continuous thin layer that conforms to the breast shape while maintaining lightweight properties.
Solution Approach 2:
The patent creates a composite structure by combining the thin polymer film with the bra cup fabric (mesh or lace material). This composite material integrates the support function of the polymer with the breathability and comfort of the fabric, achieving both reliability and lightness.
2Shape
If traditional padding is used to minimize breast projection, then shaping effectiveness is improved, but breathability and comfort deteriorate
Solution Approach 1:
The thin polymer film acts as a flexible shell that subtly redistributes breast tissue to minimize projection while maintaining breathability. Unlike thick padding, the thin film allows air circulation and does not trap heat, preserving comfort and breathability.
Solution Approach 2:
The patent applies the polymer film selectively to specific areas of the bra cup where projection control is needed, rather than using uniform thick padding throughout. This localized application provides shaping effectiveness only where necessary while maintaining breathability in other areas.
3Ease of operation
If no polymer web is used in unlined bras, then simplicity and breathability are maintained, but breast support and projection control are insufficient
Solution Approach 1:
The thin polymer film serves as a flexible shell that provides the necessary support structure without compromising breathability. The film's thinness allows air to pass through while still providing enough structural integrity for breast support and projection control.
4Reliability
If thicker polymer layers are used to enhance support, then breast support is improved, but comfort and breathability deteriorate
Solution Approach 1:
The patent deliberately uses a thin film rather than a thick layer, recognizing that the film's flexibility and conformability provide adequate support without compromising comfort. The thinness of the film ensures it does not create pressure points or trap heat, maintaining comfort and breathability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The thin polymer web enhances breast support and minimizes projection by redistributing breast tissue, offering a lightweight, breathable, and comfortable solution without traditional padding, achieving up to a 1.375-inch reduction in breast projection compared to unlined bras without the web.
Implementation Method 1
A thin polymer web comprising an aqueous polyurethane dispersion is disposed on at least one of the outer face of the mesh layer and the inner face of the lace layer of each of the first and second bra cups
