Solution Overview

Problem

Existing bras are often rigid, ill-fitting, and lack adjustability, leading to discomfort and the need for frequent replacement, with sizing inconsistencies across brands and unreliable cup size determination.

Innovation Solution

An adjustable brassiere with detachable shoulder straps and wing loops, allowing for customizable configurations such as backless, halter top, crisscross, and single-strap configurations, using a flexible material like woven fabric or tricot, and concealed underwires for structural support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a bra is designed with fixed configuration for specific activities, then it provides specialized support for that activity, but it cannot be adapted to other activities or body types

Engineering Contradiction:

Improveadaptability to different activities and body typesVSAvoidcomplexity of adjustment mechanisms

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bra is divided into separate adjustable components including detachable shoulder straps, adjustable wings, and modular cup sections. Each component can be independently adjusted or detached, allowing the bra to be customized for different activities and body types without requiring a completely different garment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bra incorporates dynamic adjustment mechanisms including slide-adjustable straps, detachable connections, and reconfigurable wing sections. These dynamic elements allow the bra to transform between different configurations (e.g., sports bra, everyday bra, backless style) to adapt to various needs.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If a bra uses standard cup sizing, then it simplifies purchasing, but sizing is inconsistent across brands and difficult to determine

Engineering Contradiction:

Improveease of sizing and fittingVSAvoidaccuracy of cup size determination

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The bra includes self-adjusting features such as multiple attachment loops along the cup edges and adjustable wings that allow the wearer to personally customize the fit. This eliminates dependency on retailer measurements and standard sizing charts, enabling the wearer to achieve the correct fit themselves.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The bra allows change in critical fit parameters including strap length, wing position, and cup attachment points. By making these parameters adjustable rather than fixed, the bra can accommodate variations in body type and preference without requiring precise standard sizing.

Inventive Principle:

Principle #35Parameter changes

3Strength

If a bra is made rigid for structural support, then it provides necessary bra support, but it becomes uncomfortable and difficult to adjust

Engineering Contradiction:

Improvestructural support capabilityVSAvoidcomfort and adjustability

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The bra uses local quality differentiation where rigid underwires and structured cups provide support in specific areas, while detachable straps and adjustable wings provide flexibility where needed. Different sections of the bra have different mechanical properties optimized for their specific functions.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The support structure is segmented into rigid underwire sections for cup support and flexible adjustable straps for positioning. This segmentation allows the rigid support elements to perform their function while the flexible elements provide comfort and adjustability.

Inventive Principle:

Principle #1Segmentation

4Adaptability or versatility

If a bra is designed as a single fixed configuration, then it is simple to manufacture, but it requires frequent replacement as it no longer fits

Engineering Contradiction:

Improvelongevity through reconfigurationVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The bra is manufactured as a modular system with separate adjustable components (straps, wings, cups) that can be reconfigured. This modular approach extends the bra's usable life by allowing it to be adapted to changing body types and preferences without requiring complete replacement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bra is designed as a universal platform that can serve multiple functions through reconfiguration. The same basic structure can function as a sports bra, everyday bra, backless style, or other variations, maximizing its utility and reducing the need for multiple garments.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An adjustable brassiere undergarment having a first cup defining an upper edge and a second cup defining an upper edge. A first wing extends laterally away from the first cup and a second wing extends laterally away from the second cup. The first wing defines a peripheral edge, and the second wing defines a peripheral edge. A plurality of attachment loops are positioned along the upper edge of each of the first cup and second cup. A plurality of wing loops positioned along a peripheral edge of the first and second wing. A first shoulder strap is configured to detachably connect to the plurality of attachment loops or the plurality of wing loops and a second shoulder strap is configured detachably connect to the plurality of attachment loops or the plurality of wing loops.
