3D X-Shaped Brassiere Support for Uplift Without Wire Irritation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unwired brassieres lack the uplifting and shaping effects provided by wired bras, while wired bras often cause irritation due to rigid materials, and 2D plastic sheet supports can be uncomfortable due to residual torque when conforming to 3D shapes.
Innovation Solution
A 3D X-shaped support made of materials like EVA, polyurethane, or fiberfill, integrated into the molding process of brassiere cups, eliminating residual torque and providing a single integral piece for both cups, enhancing comfort and shaping without the need for adhesives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If rigid metal or plastic wires are used in brassiere cups, then the cups can conform to breast curvature and provide uplift effect, but the wires cause irritation and discomfort to the wearer
Solution Approach 1:
The patent removes the wire element entirely from the brassiere design, extracting the harmful component while retaining the desired shaping function through alternative means (seamless construction and cup design)
Solution Approach 2:
The patent uses flexible cup materials that can conform to breast shapes without rigid wires, employing thin film-like structures that provide shaping while maintaining comfort and avoiding skin irritation
2Force
If 2D plastic sheet support is used to provide lifting effect, then the support can be stiff enough for shaping, but it creates residual torque when conforming to 3D garment shapes
Solution Approach 1:
The patent transitions from 2D plastic sheet support to 3D molded cup structures, adding dimensional complexity that allows the support to conform to curved surfaces without creating residual torque, while maintaining lifting capability
Solution Approach 2:
The patent changes the physical parameters of the support material through molding processes, creating three-dimensional structures with varying density and firmness that provide lifting support without the torque problems of flat 2D sheets
3Force
If wired brassiere structure is used to provide maximum push up effect, then the breast uplift and shaping is enhanced, but the wire ends can poke the breasts causing red marks and discomfort
Solution Approach 1:
The patent completely removes the wire element from the design, eliminating the source of poking and red marks while maintaining push-up effect through alternative structural approaches
Solution Approach 2:
The patent employs flexible, seamless cup constructions that distribute pressure evenly across the breast surface, replacing rigid wire structures with soft, conforming materials that prevent poking and discomfort
