Reduced-Coverage Back-Smoothing Brassiere with Catenary Curves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional brassieres cause unsightly skin bulges and discomfort, especially for fuller-bodied women, due to their bulky design and high modulus of elasticity fabric, which restricts movement and limits clothing choices.
Innovation Solution
A reduced-coverage back-smoothing brassiere design featuring brassiere wings and straps with a smaller footprint, using a fabric with lower modulus of elasticity and a catenary shape to provide continuous, unbroken concave curves for improved comfort and discreet coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional brassieres use oversized wings and straps with high modulus of elasticity fabric to prevent skin bulges, then back smoothing effect is improved, but comfort and breathability deteriorate due to heavy material and restricted movement
Solution Approach 1:
The patent changes the modulus of elasticity parameter of the fabric from high to low, making the material softer and more compliant. This allows the brassiere to conform to the body's natural contours without creating pressure points or skin bulges, while simultaneously improving comfort and breathability for extended wear
Solution Approach 2:
The patent employs catenary curves and continuously curved lines in the wing and strap design, replacing straight edges and angular shapes. These smooth curves naturally follow the body's contours, distributing pressure evenly and preventing skin bulges without requiring oversized rigid structures
2Strength
If traditional brassieres use multiple layers of fabric with high modulus of elasticity power mesh to provide support and shaping, then structural support is improved, but weight and heat retention increase causing discomfort during prolonged wear
Solution Approach 1:
The patent reduces the modulus of elasticity of the fabric, transitioning from stiff, structured materials to softer, more flexible fabrics. This parameter change maintains sufficient support through improved conformity and pressure distribution while significantly reducing weight and heat retention
Solution Approach 2:
The patent utilizes composite fabric constructions that combine different material properties to achieve both support and comfort. The multi-layer fabric structures are designed with varying densities and compositions to provide necessary structural integrity without excessive weight
3Object-affected harmful factors
If back smoothing brassieres use oversized wings extending across the back to create a V-shape opening, then coverage and smoothing effect are improved, but visibility under delicate clothing increases and clothing options are limited
Solution Approach 1:
The patent uses continuous catenary curves to define the wing edges, creating smooth, natural-looking lines that blend seamlessly under clothing. These curved edges eliminate sharp angles and straight lines that would be visible under delicate fabrics, providing back smoothing that remains invisible beneath various clothing styles
Solution Approach 2:
The patent applies different edge configurations to different portions of the wings. The interior edges feature continuous curves for smoothing, while the exterior edges are designed to be less visible. This localized differentiation allows the brassiere to provide smoothing where needed while remaining compatible with diverse clothing options
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 design offers comfortable long-term wear, supports breasts without bulges, and allows for a wider range of clothing options by minimizing back coverage, providing a seamless fit under delicate tops.
Implementation Method 1
The power mesh can be a fabric that applies independent elastic forces in two dimensions (e.g., horizontally and vertically) when stretched

AI summary
An example reduced-coverage back-smoothing brassiere includes a right and left brassiere cup, right and left brassiere wings, each coupled to at least a portion of one of the two brassiere cups and one of two brassiere straps, first edges of the brassiere wings each being a continuous curve leading to the exterior edge of the respective brassiere wing, the second portion of the right brassiere strap being coupled to the right brassiere cup and the second portion of the left brassiere strap being coupled to the left brassiere cup, a second edge of each of the brassiere wings extending in an unbroken curve from the respective brassiere strap toward the fastening section, a continuous, unbroken curve being created by the interior edge of each of the two brassiere straps along the second edge of each of the two brassiere wings, respectively.
