Kidney-Shaped Push-Up Insert with Asymmetric Lobes

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing bra pads do not effectively push up breasts, create cleavage, or provide anatomical fit, resulting in unnatural-looking enhanced volume.

Innovation Solution

A kidney-shaped push up insert with a first and second lobe, featuring a notch and depression design, made from a soft, non-porous polymer or gel, is anatomically contoured to conform to the breast, providing lift and support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If prior art foam pads are used to fill out the bra, then the bra cup is filled, but the pads do not push up breasts or create cleavage and volume

Engineering Contradiction:

Improvebreast shape and cleavageVSAvoidpad design complexity

Core Design Contradiction:

ShapeVSEase of manufacture

Solution Approach 1:

The push-up insert is divided into multiple lobes (first lobe, second lobe, third lobe) with different thicknesses and shapes, each targeting specific breast areas to create natural cleavage and lift, rather than using a single uniform pad design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the insert have different thicknesses and densities - the first lobe has greater thickness for primary support, the second lobe has intermediate thickness, and the third lobe has lesser thickness, creating localized support zones that push up breasts naturally

Inventive Principle:

Principle #3Local quality

2Shape

If prior art plastic pads are used, then the bra cup is filled, but the pads do not wrap around breasts or conform to the breast to create a natural shape

Engineering Contradiction:

Improveanatomical fit and natural shapeVSAvoidinsert structure

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

The insert features curved, organic contours including a concave upper surface and convex lower surface that wrap around the breast anatomy, with rounded edges and a kidney-bean overall shape that conforms to natural breast curvature rather than angular geometric shapes

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The insert employs asymmetric lobe configurations where the first lobe extends further toward the center gore, the second lobe has intermediate reach, and the third lobe extends least, creating an asymmetric pattern that naturally follows breast asymmetry and positioning

Inventive Principle:

Principle #4Asymmetry

3Force

If thin foam pads about 1/2 inch thick are used, then the bra cup is filled, but the pads do not provide lift or greater cleavage

Engineering Contradiction:

Improvepush-up force and liftVSAvoidinsert thickness

Core Design Contradiction:

ForceVSVolume of moving object

Solution Approach 1:

The insert uses variable thickness distribution with the first lobe having maximum thickness for primary push-up force, the second lobe having intermediate thickness for secondary support, and the third lobe having minimum thickness for subtle enhancement, optimizing lift without uniform bulk

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The insert combines foam material with fabric outer layers and elastic components to create a composite structure that provides both cushioning for comfort and structural integrity for sustained push-up force generation

Inventive Principle:

Principle #40Composite materials

4Shape

If prior art pads are used, then the bra cup is filled, but the pads do not provide natural-looking enhanced cleavage

Engineering Contradiction:

Improvecleavage appearanceVSAvoidinsert placement and positioning

Core Design Contradiction:

ShapeVSEase of operation

Solution Approach 1:

The insert is pre-shaped and pre-contoured during manufacturing with lobes positioned to automatically align with breast anatomy upon insertion, eliminating the need for complex folding, rolling, or adjustment by the user for proper positioning

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The single insert design performs multiple functions simultaneously: the first lobe provides primary support and lift, the second lobe provides secondary support, the third lobe provides subtle enhancement, and the overall shape creates cleavage, eliminating the need for multiple separate components

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Kidney-shaped push up insert including first lobe and second lobe is provided. Notch is formed in top side between first lobe and second lobe. Insert has depression formed adjacent top side extending towards notch. Second main surface opposes first main surface. Second main surface is substantially smooth arcuate-shaped surface. First lobe has narrower width between top side and bottom side than second lobe, and second lobe is thicker between first main surface and second main surface than first lobe. Ratio of maximum thickness between first main surface and second main surface to maximum length between opposing ends of first lobe and second lobe is less than about 9 and/or ratio of depth of notch from a straight line connecting first lobe and second lobe along top side of insert to width of insert from top side to bottom side at depth of notch is less than about 4.
