Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional bras often fail to accommodate breasts of different cup sizes, leading to discomfort, difficulty in fitting, and challenges in putting them on, especially for elderly or disabled individuals, due to rigid straps, misaligned hooks and eyes, and lack of symmetry support.

Innovation Solution

A bra design featuring two separate sides with different cup sizes, an infinity under band for flexible attachment, and a soft microfiber construction without wires or adjustable straps, allowing for easy fitting and adjustment without a center front, using a non-metallic hook system and breathable materials for comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If conventional bras use rigid straps and fixed cup sizes, then structural stability is improved, but comfort and adaptability to different breast sizes deteriorate

Engineering Contradiction:

Improvestructural stabilityVSAvoidadaptability to different breast sizes

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The bra is divided into two separate sides, each with its own cup, strap, and closure system. This segmentation allows each side to be independently sized and adjusted to match the wearer's specific breast dimensions, eliminating the need for compromise in traditional symmetric bras.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bra incorporates adjustable straps and flexible closure systems that can be dynamically reconfigured. The straps feature multiple adjustment points allowing length modification, and the closure system enables repositioning to accommodate different body shapes and sizes.

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If conventional bras use fixed cup sizes, then manufacturing simplicity is improved, but ease of fitting and comfort deteriorate

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidease of fitting

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

By manufacturing separate left and right sides as independent units, each can be produced to precise specifications for different cup sizes. This modular approach simplifies the manufacturing process while enabling extensive size variation, as each component can be mass-produced and then assembled according to customer needs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bra design incorporates universal adjustment mechanisms that work across all cup sizes. The same strap adjustment system, closure type, and structural features are used throughout, allowing a single design platform to serve multiple size configurations without requiring entirely different manufacturing processes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Strength

If conventional bras use rigid straps for stability, then structural support is improved, but comfort and ease of putting on deteriorate

Engineering Contradiction:

Improvestructural supportVSAvoidease of putting on

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The straps are designed with dynamic adjustment capabilities, featuring multiple attachment points and flexible length modification. This allows the straps to be configured for optimal support strength while maintaining flexibility during the putting-on process, eliminating the need for rigid fixed-length straps.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The strap system allows modification of key parameters including length, attachment position, and tension. These parameter changes enable the same strap structure to provide both the necessary structural support and the flexibility needed for easy donning and adjustment.

Inventive Principle:

Principle #35Parameter changes

4Manufacturing precision

If conventional bras use fixed closure positions, then manufacturing precision is improved, but adaptability to different body types deteriorates

Engineering Contradiction:

Improveclosure alignmentVSAvoidadaptability to different body types

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The closure system incorporates multiple repositionable attachment points along the band and strap structures. These points are precisely manufactured at predetermined locations, allowing the closure to be dynamically repositioned to accommodate different body types, rib cage positions, and fit preferences while maintaining manufacturing precision.

Inventive Principle:

Principle #15Dynamics

AI summary

A bra including respective first and second sides each adapted to fit respective breasts; each side including a cup adapted to fit a predetermined cup size; a hook free shoulder strap; and an attachment strap capable of attaching the bra to a body in use, wherein the attachment strap includes a plurality of slots which can be engaged by a hook located at one end of the strap to thereby regulate the size of the bra for each user.
