Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing garments with straps, such as bras, often require multiple purchases to match fashion trends, and conventional strap covers can be uncomfortable and prone to 'bunching' due to poor fastening mechanisms, leading to visibility of the underlying straps.

Innovation Solution

A system integrating designer strap covers with underlying garments using hook-and-loop fastener tapes, elastic fasteners, and secure attachment methods like magnets and snap fasteners, allowing for adjustable and removable covers that elongate with the strap, preventing bunching and discomfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional strap covers are used, then the garment strap is concealed, but the cover is uncomfortable and prone to bunching due to poor fastening mechanisms

Engineering Contradiction:

Improveconcealment of garment strapVSAvoidcomfort and bunching resistance

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The strap cover is designed to be elastic and stretchable, allowing it to dynamically adjust to the movement and stretching of the underlying garment strap. This dynamic adaptation prevents bunching and maintains comfort throughout wear, resolving the contradiction between concealment and comfort.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The fastening mechanism uses elastic materials that can change their physical parameters (stretchability, elasticity) to match the underlying strap's movement. This parameter change allows the cover to remain comfortable and prevent bunching while maintaining effective concealment.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If multiple bras of different color and design are purchased to match fashion trends, then fashion flexibility is achieved, but cost increases

Engineering Contradiction:

Improvefashion flexibilityVSAvoidnumber of garments purchased

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The bra system is segmented into two independent components: the base bra and the interchangeable strap cover. This segmentation allows the cover to be separated and replaced independently, enabling fashion flexibility without requiring multiple complete bra purchases.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base bra is designed with universal attachment mechanisms (hooks, eyes, or elastic edges) that can accommodate multiple different strap cover designs. This multi-functionality allows a single bra to work with various fashion trends through interchangeable covers, reducing the need to purchase multiple bras.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If strap covers are made detachable and interchangeable, then fashion versatility is improved, but the fastening mechanism becomes more complex

Engineering Contradiction:

Improveinterchangeability of strap coversVSAvoidfastening mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fastening mechanism is designed to be self-service, using simple elastic properties and basic mechanical elements (hooks, eyes, or elastic edges) that can be easily attached and detached without complex tools or mechanisms. This maintains interchangeability while minimizing complexity.

Inventive Principle:

Principle #25Self-service

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

The system provides a comfortable, adjustable, and aesthetically pleasing solution by concealing garment straps, accommodating movement without bunching, and allowing for interchangeable designs with a single garment piece, reducing the need for multiple purchases.

Implementation Method 1

hook-and-loop style fastener tapes cover a top surface of a garment strap as well as a bottom surface of a designer strap

Methodology Applied

Scientific EffectHook-and-loop fastening: Velcro

Implementation Method 2

stretchy loop-style fastener tape... The elasticity of the underlying tapes or base of these 'stretchy' fasteners provides an increase in comfort for the wearer as compared to other fastening mechanisms

Methodology Applied

Scientific EffectElasticity: Elasticity

Implementation Method 3

one or more magnets sewn into the fabric of the cup

Methodology Applied

Scientific EffectMagnetic attraction: Magnetism

AI summary

A bra strap cover system is disclosed. The system includes a bra including at least one shoulder strap and a decorative bra strap cover. The shoulder strap of the bra includes a plurality of fasteners attached to its upper surface. The underside of the bra strap cover includes a plurality fasteners attached thereto. The bra strap cover is configured to be removably attached to the bra strap such that the bra strap cover substantially covers and overlies the upper surface of the shoulder strap.
