Solution Overview

Problem

Designing shapewear for special occasion garments with low cut necklines and back lines is challenging due to the need for effective shaping while minimizing material in the chest and back regions, and ensuring the shapewear is not visible beneath ultra low-back garments.

Innovation Solution

A shaping garment with a rear side space and a removable back adjuster that bridges this space, featuring left and right closure mechanisms, elastic bands, and U-shaped wire support for breast shaping, allowing versatile wear with various special occasion garments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the shaping garment eliminates material from the back region to be invisible under ultra low-back garments, then the visibility of the shaping garment is reduced, but the shaping support and coverage are reduced

Engineering Contradiction:
Improvevisibility of shaping garmentVSAvoidshaping support
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The back shaping region is divided into left and right portions separated by a superior edge, creating distinct functional zones that can independently provide shaping support while maintaining overall invisibility under ultra low-back garments

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The superior edge extends upward from the rear lowermost area to define a space between left and right back shaping regions, creating a three-dimensional structure that provides shaping support without adding visible bulk or material in the back region

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If the shaping garment is designed for effective shaping with minimal material, then the material quantity is reduced, but the versatility to adapt to different special occasion garments is reduced

Engineering Contradiction:
Improvematerial in chest and back regionsVSAvoidadaptability to special occasion garments
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The removable back adjuster can be attached or detached based on the specific occasion garment being worn, allowing the shaping garment to dynamically adapt between ultra low-back mode (adjuster removed) and low-back mode (adjuster attached), thereby providing versatility without adding permanent material

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The shaping garment is designed to serve multiple functions: it can be worn with ultra low-back garments (with adjuster removed) or low-back garments (with adjuster attached), making it a universal solution for different types of special occasion wear

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If the removable back adjuster is added to provide additional shaping support, then the shaping support is improved, but the device complexity increases

Engineering Contradiction:
Improveshaping supportVSAvoidgarment structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The back adjustor is designed as a separate, removable component that can be detached when not needed, allowing the shaping support function to be extracted and added only when required, thereby minimizing the permanent structural complexity of the garment

Inventive Principle:
Principle #2Taking out (Extraction)

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 solution provides effective shaping support while ensuring the shapewear remains hidden under ultra low-back garments, offering adaptability and comfort through adjustable configurations.

Implementation Method 1

An elastic band can be positioned inferior to the breast supporting portion, and the elastic band can extend laterally towards the rear side of the shaping garment

Methodology Applied
Scientific EffectElasticity: Elasticity

Implementation Method 2

The left closure mechanism and/or the right closure mechanism can include hook and/or eye fasteners

Methodology Applied
Scientific EffectMechanical Fastener: Mechanical Fastener

AI summary

Designing shapewear for special occasion garments with low cut necklines and back lines can be especially challenging. The challenge lies in constructing a garment that effectively shapes the wearer while simultaneously eliminating significant amounts of material from the chest and/or back region. Disclosed herein are shaping garments designed to be worn underneath garments with low cut back lines. The shaping garment includes a space in the back shaping region on its rear side, such that the shaping garment is not visible beneath an ultra low-back special occasion garment. A removable back adjuster can be used to bridge the space to provide additional shaping support when ultra low-back mode is not required by the special occasion garment.
