Solution Overview

Problem

Current women's apparel often lacks integrated breast support, leading to exposure of bra straps, irritation from independent strap movement, and inadequate shapeliness, especially in tank tops and sports bras.

Innovation Solution

A soft, knit tank top with a built-in bra featuring double-layered cups and front straps constructed from the same fabric, connected partially along the neckline, and a floating back panel with compression fabric for tension support, allowing for removable inserts for customizable coverage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a separate bra is worn with an upper garment, then breast support is provided, but the bra strap can be displaced and exposed beneath the garment strap creating an unkempt look

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidstrap arrangement
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The patent combines the bra and upper garment into a single integrated article of clothing. The bra component is constructed with the same fabric as the garment body, and the straps are merged so that the garment strap completely covers the bra strap, eliminating the displaced strap appearance while maintaining breast support functionality.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a separate bra is worn with an upper garment, then breast support is provided, but the independent movement of the two straps on a woman's shoulder causes irritation and requires repeated manual adjustment

Engineering Contradiction:
Improvestrap alignmentVSAvoidstrap adjustment
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent merges the bra strap and garment strap into a single continuous strap structure. This unified strap design eliminates independent movement between separate straps, preventing irritation and the need for repeated adjustment while ensuring reliable strap alignment throughout wear.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If an ordinary standalone bra is attached to an outer garment, then adequate breast support is provided, but the garment cannot move freely relative to the body of the bra

Engineering Contradiction:
Improvebreast supportVSAvoidgarment movement
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the attachment points to only the strap region rather than fixing the bra to multiple portions of the garment body. This selective attachment at the straps allows the garment body to move freely relative to the bra cups and front region, maintaining both breast support and garment flexibility.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If a shelf bra design is used, then comfort is improved, but the unstructured nature does not provide as much support or shapeliness

Engineering Contradiction:
ImprovecomfortVSAvoidbust line shapeliness
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The patent uses composite construction combining structured and unstructured elements. The bra incorporates an underwire or elastic strip for structured support, while the cups are made from soft knit fabric for comfort. This composite approach provides both the comfort of unstructured designs and the shapeliness of traditional bras.

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

Provides improved comfort, shapeliness, and supportiveness while eliminating the unkempt look of exposed bra straps and reducing the need for a separate bra, offering a lightweight, flexible garment for active wear.

Implementation Method 1

A floating back panel and back straps of the bra are made with a single-layer of compression fabric to provide tension support and anchor the front

AI summary

The present invention provides a garment comprising a soft, knit tank top with a built-in, floating bra. The bra cups and front bridge are constructed with the same fabric as the tank top. Bra cups connect to the tank top partially along front neckline and are double-layered to provide space for removable and inter-changeable sized inserts for different levels of coverage. A floating back panel is made with a single-layer of compression fabric to provide tension support and anchor the front. The straps of the tank top are double-layered shell fabric and connect at a top of the shoulder to wide, flat-lock stitched vertical back bra straps made with compression fabric. This tank top with built-in bra support is a bra replacement worn as a stand-alone top garment or a layering piece underneath outer layers.
