Solution Overview

Problem

Conventional bras lack a practical mechanism for accessing the breast during nursing without requiring removal or significant adjustment, which can be cumbersome and inconvenient.

Innovation Solution

A convertible nursing bra design featuring releasable support cups that detach from straps, with auxiliary attachment devices to maintain support and facilitate easy access and re-covering, utilizing underlying support panels connected to encircling straps or underwire support for continued support during nursing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the bra is designed with fixed support cups, then support is maintained, but access to the breast requires removal or dislocation of the entire bra which is cumbersome

Engineering Contradiction:
ImproveAccess to breastVSAvoidBra structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The bra is divided into separable components: support cups that can be detached from the main bra body. This allows the cups to be removed independently for breastfeeding access while the support structure remains in place, eliminating the need to remove the entire bra.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bra incorporates dynamic elements including snap fasteners and adjustable straps that allow the structure to change configuration. The cups can be quickly attached and detached, and the straps can be repositioned to maintain support during the nursing process.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the support cups are removed completely for access, then full access is achieved, but support is lost and re-attachment is cumbersome

Engineering Contradiction:
ImproveAccess to breastVSAvoidSupport during nursing
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

By separating the support cups from the main bra body through detachable connections, the system allows selective removal of only the cup portion needed for access while preserving the support structure. This maintains reliability of support during nursing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The snap fasteners and connection mechanisms serve as intermediaries between the cups and the bra body, enabling quick attachment and detachment while maintaining a secure connection when attached. This facilitates easy access while ensuring reliable support when needed.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the bra requires two hands for removal and readjustment, then complete coverage is maintained, but convenience is significantly reduced

Engineering Contradiction:
ImproveConvenience of useVSAvoidTime for adjustment
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The bra incorporates dynamic fastening systems with snap buttons and adjustable straps that can be operated with one hand. The cups can be quickly detached and reattached without requiring both hands, significantly reducing adjustment time and improving convenience for nursing mothers.

Inventive Principle:
Principle #15Dynamics

AI summary

A convertible nursing bra, in an exemplary embodiment, having bra support cups releasable from straps to provide access and further including underlying support panels connected to the encircling strap or under wire support and remaining connected to the straps to provide continued support during nursing. Released portions of the cups are temporarily retained by auxiliary attachment devices on the encircling strap to reduce interference during nursing. The releasable cup-to-strap and/or cup-to-encircling strap connecting devices are easily managed for access, stowing and re-covering.
