Solution Overview

Problem

Conventional wire-free bras often lack adequate support and aesthetics, causing discomfort and sagging due to insufficient breast support, which can result in a less attractive appearance.

Innovation Solution

A lightweight, unpadded wire-free bra design featuring cups with skived foam layers and a sling portion made of elastic material, providing independent motion and a push-in effect by positioning the sling to offer both lateral and vertical support, creating a deeply plunging cleavage without visible underwires.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional wire-free bras are used, then comfort is improved by eliminating underwires, but breast support is insufficient causing discomfort and sagging

Engineering Contradiction:
Improvediscomfort from underwiresVSAvoidbreast support
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The invention removes the underwire component from the bra structure entirely, extracting the harmful element while retaining the essential support function through alternative means (cups and front connecting portion)

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention uses flexible cup structures with foam layers and elastic materials to provide support without rigid underwires, allowing the cups to conform to breast shape while maintaining support through material elasticity and structural design

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of operation

If wire-free bra design is used, then comfort is improved, but aesthetic appearance deteriorates due to sagging and flattening

Engineering Contradiction:
ImprovecomfortVSAvoidbreast appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The invention changes the structural parameters of the cup (depth, connectivity, material composition) to achieve both comfort and aesthetic appearance, specifically creating a deeper cup design that maintains shape while remaining wire-free

Inventive Principle:
Principle #35Parameter changes

3Shape

If cups are connected only by front connecting portion, then deeply plunging cleavage is achieved, but structural stability may be compromised

Engineering Contradiction:
Improvecleavage depthVSAvoidcup stability
Core Design Contradiction:
ShapeVSStability of the object's composition

Solution Approach 1:

The invention uses composite cup construction with foam layers, elastic materials, and fabric components to provide structural stability while maintaining the deep plunging cleavage effect through selective front connectivity

Inventive Principle:
Principle #40Composite materials

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 bra offers comfortable, substantial breast support and a visually appealing push-in effect, enhancing the wearer's appearance by allowing independent motion of the cups and providing a natural-looking cleavage without the discomfort of underwires.

Implementation Method 1

The sling portion may comprise an elastic material, such as a nylon/spandex mesh or fabric or a fabric with a mechanical stretch made of 100% nylon

Methodology Applied
Scientific EffectElasticity: Elasticity

AI summary

A lightweight, substantially unpadded, comfortable, push-in, wire-free bra has, when worn by a female wearer, a front including a pair of cups. Each cup defines upper inner and outer portions, lower inner and outer portions, a top, and a bottom, and is configured and dimensioned to hold substantially one breast of a female wearer. Each cup includes a sling portion that is designed to provide lateral support to the respective breast. In this manner, the sling portions bias the cup upper outer portions inwardly to provide push-in cleavage on the wearer's breasts. Straps are secured to the front for releasably supporting it on a female wearer with the breasts of the female wearer substantially within the cups.
