Bra Cup Convex Foam Layers Channel Lift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for increasing the visual appearance of a woman's bustline without invasive surgical procedures are limited, as they do not effectively provide a natural and substantial enhancement of two cup sizes.
Innovation Solution
A bra cup design featuring inner and outer foam layers forming convex portions that create a channel, providing upward and inward lift, with the outer cup section appearing seamless and larger than the inner cup section, enhancing the breast's projection and shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If plastic surgery with soft implants is used to increase cup size, then the visual appearance of breast size is improved, but the complexity and risk of invasive procedures increases
Solution Approach 1:
The bra cup is divided into multiple foam layers (first foam layer, second foam layer, third foam layer) with different densities and properties. Each layer performs a specific function: the first layer provides structural support, the second layer creates the convex portions for lift, and the third layer provides comfort and seamless appearance. This segmentation allows the bra to achieve surgical-level enhancement without actual surgery.
Solution Approach 2:
The bra cup structure embeds multiple functional layers within each other - the foam layers are nested within the cup structure, with the convex portions formed by the second foam layer nested between the first and third layers. This nested arrangement creates the illusion of larger breast size while maintaining a natural, seamless appearance without requiring external implants.
2Shape
If convex portions are added to inner cup portion to create lift, then the breast projection and shape is improved, but the structural complexity of the cup increases
Solution Approach 1:
The convex portions are formed by combining the first and second foam layers into a single integrated structure during the molding process. The second foam layer is positioned between the first and third foam layers, and all layers are molded together as one piece, creating the convex portions that provide lift while maintaining structural integrity and avoiding separate complex components.
Solution Approach 2:
The bra cup uses foam materials with different density parameters and physical properties for each layer. The first foam layer has higher density for support, the second foam layer has medium density for creating convex portions, and the third foam layer has lower density for comfort. This parameter variation allows the structure to achieve enhanced breast projection while keeping the overall cup design relatively simple.
3Shape
If multiple foam layers are used to create the bra cup, then the visual enhancement of two cup sizes is achieved, but the manufacturing complexity increases
Solution Approach 1:
Multiple foam layers are molded together as a single integrated bra cup structure in one manufacturing process. The first, second, and third foam layers are positioned and bonded together during the molding process, creating the convex portions and channel structures as one piece. This merging approach achieves the visual enhancement of two cup sizes while avoiding the need to manufacture and assemble separate components, thereby simplifying production.

AI summary
A bra cup (2) includes: an inner cup portion (20), comprising one or more inner foam layers; and an outer cup portion (10), attached to the inner cup portion, comprising one or more outer foam layers, the inner cup portion and the outer cup portion together forming the bra cup. The inner foam layers form first and second convex portions (21,22) with respect to an inner surface of the inner cup portion. The first and second convex portions form, at an intersection therebetween, a channel (50) on the inner surface extending from a lower portion of the cup towards an apex of the bra cup.
