Breast Cup Groove Ventilation Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Breast cups in undergarments often fail to dissipate heat effectively, causing discomfort during hot weather or exercise due to their close fit with the body.
Innovation Solution
A breast cup design featuring a cup core with grooves on both surfaces, where only the top part of the groove sidewalls are attached to fabric layers, creating air channels for enhanced ventilation, while the bottom parts are not attached, allowing for improved air circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the breast cup is designed with a close fit to the body, then the visual effect is improved, but the heat dissipation performance deteriorates
Solution Approach 1:
The breast cup structure is segmented into multiple functional layers: a breathable outer fabric layer, a foam core layer with heat dissipation grooves, and an inner fabric layer. This segmentation allows each layer to perform its specific function - the outer layer provides close fit and aesthetics, while the inner layers handle heat dissipation through structured air channels
Solution Approach 2:
The breast cup incorporates porous and grooved structures within the foam core layer, creating numerous air channels and void spaces. These porous features enable air circulation and heat dissipation while maintaining the overall shape and close fit of the breast cup against the body
2Shape
If the breast cup is designed with a close fit to the body, then the visual effect is improved, but the air circulation deteriorates
Solution Approach 1:
The breast cup is divided into distinct layers with the foam core containing segmented grooves that create independent air channels. This segmentation allows air to circulate through multiple pathways while the outer fabric layer maintains close contact with the body for visual purposes
Solution Approach 2:
The design adds a dimensional aspect to air circulation by creating three-dimensional grooved channels within the foam core layer. These channels provide volumetric air flow paths without compromising the two-dimensional close fit of the outer fabric layer against the body surface
3Strength
If the entire sidewall of the groove is attached to the fabric layer, then the structural strength is improved, but the ventilation performance deteriorates
Solution Approach 1:
The attachment between the foam core and fabric layer is applied selectively rather than uniformly. The sidewalls of the grooves are attached to provide structural support, while the bottom portions of the grooves are left unattached to maintain open air channels. This local differentiation of attachment quality optimizes both strength and ventilation
Solution Approach 2:
The foam core material itself provides structural strength while its inherently porous nature, combined with the grooved channels, ensures ventilation. The partial attachment strategy preserves the porous air pathways at the groove bottoms while maintaining overall structural integrity through sidewall attachment

Function Achieved in This Case
The design effectively enhances heat dissipation, reducing discomfort by facilitating airflow and improving ventilation, especially during physical activity or hot weather.
Implementation Method 1
A top part of the sidewalls of one or more of the plurality of the first grooves is attached to the first fabric layer while at least a portion of the bottom of the one or more of the plurality of the first grooves is not attached to the first fabric layer

AI summary
A breast cup for an undergarment, such as a brassiere, includes a cup core that has a first surface and a second surface opposite the first surface. Each of the first and second surfaces is formed with a plurality of grooves. Each groove has an elongated opening, an elongated bottom, and a sidewall on each of two longitudinal sides of the groove. The breast cup also includes a first fabric layer overlying the first surface of the cup core, and a second fabric layer overlying the second surface of the cup core. A top part of the sidewalls of one or more of the plurality of the first grooves is attached to the first fabric layer while at least a portion of the bottom of the one or more of the plurality of the first grooves is not attached to the first fabric layer.
