Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional bra strap systems often experience side slip on the shoulders due to inadequate vertical support, compromising the fit and comfort of brassieres, especially when worn under other garments.

Innovation Solution

The bra strap system incorporates adjustable straps with elastic connections and anchor loops that provide both vertical and horizontal force components, preventing side slip while maintaining support, through a unique configuration of straps and buckles that can be adjusted and secured using a hook mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional bra straps are used that pass over the shoulders to fasten at the back, then the brassiere can be secured around the torso, but the straps may ride out on the shoulders and become exposed

Engineering Contradiction:

Improvestrap position stabilityVSAvoidside slip exposure

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

An intermediary horizontal strap is introduced that connects the two vertical bra straps at shoulder level. This intermediary strap acts as a mediator that prevents the vertical straps from sliding outward by providing a stabilizing connection across the shoulders, thereby eliminating the side slip exposure problem while maintaining the original strap configuration

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The solution adds a horizontal dimension to the traditionally vertical strap arrangement. By introducing a horizontal strap component that connects left and right straps, the system creates a two-dimensional stabilizing structure that prevents outward sliding without compromising the vertical support function

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If an intermediary horizontal strap is added to prevent side slip, then strap exposure is reduced, but the vertical support of the straps is compromised

Engineering Contradiction:

Improveside slip exposureVSAvoidvertical support force

Core Design Contradiction:

Object-affected harmful factorsVSForce

Solution Approach 1:

The vertical straps are designed to perform multiple functions simultaneously: they provide vertical support for the breasts while also serving as attachment points for the horizontal stabilizing strap. This multi-functionality allows the system to maintain vertical support efficacy while gaining side slip prevention capability through the same strap structure

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If the strap length is fixed, then the brassiere provides stable support, but the fit cannot be adjusted for different wearers or occasions

Engineering Contradiction:

Improvesupport stabilityVSAvoidstrap length adjustment

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The strap system incorporates adjustable length mechanisms that allow the straps to dynamically change their effective length. This enables the same brassiere to adapt to different wearer sizes and preferences while maintaining stable support through proper tensioning, thus achieving both reliability and adaptability

Inventive Principle:

Principle #15Dynamics

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

This configuration ensures that the straps remain securely in place on the shoulders, preventing side slip while maintaining vertical support and allowing for adjustable fit, enhancing the overall comfort and stability of the brassiere.

AI summary

An aftermarket bra strap ensemble has two adjustable straps, each having an unattached end, and a strap buckle on the other end, and two double straps, one passing through a loop of the strap buckle on the end of each of the two adjustable straps. The double straps also pass through an anchor loop at ends away from the strap buckles of the adjustable straps, and opposite ends of the double straps attach to separate anchor rings, one of which is adapted to hook to the other.
