Solution Overview

Problem

Current bra sizing systems fail to provide a correct fit for smaller sizes and immovable breasts, as they are scaled down from larger sizes without considering the anatomical differences, leading to mispositioned cups and inadequate support.

Innovation Solution

The solution involves maintaining the same outer diameter as a 34B cup for a 34A cup by creating a fill inside to accommodate the larger diameter and positioning cups wider apart to accommodate the wider spread of immovable breast tissue, ensuring the gore touches the body for proper fit and function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If cups are scaled down proportionally from larger sizes, then cup volume is reduced, but cup position becomes incorrect and cups are too close together

Engineering Contradiction:
Improvecup volumeVSAvoidcup position
Core Design Contradiction:
Volume of moving objectVSManufacturing precision

Solution Approach 1:

The patent applies local quality by maintaining the outer diameter and position of cups for smaller sizes the same as larger sizes, while only reducing the inner volume to match smaller breast tissue. This ensures cups remain in the correct anatomical position while accommodating smaller breast volume, resolving the contradiction between reduced cup volume and correct cup positioning.

Inventive Principle:
Principle #3Local quality

2Volume of moving object

If cup perimeter is reduced proportionally, then cup volume decreases, but lower edge of cup is mispositioned on chest wall

Engineering Contradiction:
Improvecup volumeVSAvoidcup perimeter position
Core Design Contradiction:
Volume of moving objectVSLength of stationary object

Solution Approach 1:

The patent maintains the outer perimeter and lower edge position of cups the same as larger sizes, while reducing only the inner volume. This local differentiation ensures the cup remains correctly positioned on the chest wall while accommodating smaller breast tissue volume, resolving the contradiction between reduced volume and correct positioning.

Inventive Principle:
Principle #3Local quality

3Shape

If cups are positioned closer together, then cleavage is created for larger breasts, but gore cannot touch the body for smaller breasts

Engineering Contradiction:
ImprovecleavageVSAvoidgore contact
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The patent inverts the conventional approach by positioning cups wider apart for smaller sizes instead of closer together. This allows the gore to touch the body and provides proper support for smaller breasts, while larger sizes maintain closer cup positioning for cleavage. The principle of inverting the cup positioning strategy resolves the contradiction between cleavage and gore contact.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

A brassiere includes a first wing and a second wing, a closure including a first closure portion on a first end of the first wing, and a second closure portion on a first end of the second wing; a pair of cups including a first cup connected to the second end of the first wing, and a second cup connected to the second end of the second wing; each cup including an inner contour shaped with an inner apex matching a breast to receive the breast in a natural bust point position, and an outer contour having a size larger than the inner contour and shaped with an outer apex spaced medially from the inner apex, and filling material between the inner contour and the outer contour; a gore connected between the first cup and the second cup; and a pair of straps including a first strap connected to the first cup and the first wing, and a second strap connected to the second cup and the second wing.
