Twisted Wire Support Frame for Bra Cleavage Shaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing low-heart underwear and bras with semicircular support loops fail to effectively outline the cleavage area, limiting heart position and failing to enhance the aesthetic presentation of the cleavage line, while also compromising comfort and aesthetics.
Innovation Solution
A three-dimensional heart position support frame with U-shaped wire surfaces twisted at varying angles to fit closely with breast contours, allowing for adjustable support and a three-dimensional shape outline, using materials like stainless steel, polyester plastic, or silica gel wires for comfort and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a semicircular support loop is arranged in two cups, then heart position is limited, but the cleavage line cannot be outlined effectively and aesthetic presentation is compromised
Solution Approach 1:
The patent transitions from a traditional two-dimensional semicircular support loop to a three-dimensional heart position support frame with twisted wire surfaces. This dimensional change enables the support frame to create volume and depth at the cleavage area, effectively outlining the cleavage line while maintaining heart position support. The twisted wire surfaces extend outward to form a three-dimensional structure that shapes the breast contour.
Solution Approach 2:
The patent employs curved and twisted wire surfaces instead of flat or simple semicircular shapes. The wire surfaces are twisted at varying angles and curved outwardly to match breast contours, creating a spheroidal or three-dimensional form that effectively outlines the cleavage area. This curvature principle transforms the flat support loop into a volumetric shaping structure.
2Device complexity
If a semicircular support loop is used, then the structure is simple, but it fails to coordinate outerwear to accentuate cleavage line
Solution Approach 1:
The three-dimensional heart position support frame serves multiple functions simultaneously: it limits heart position, outlines the cleavage line, creates a three-dimensional breast shape, and coordinates with various outerwear styles. This multi-functional design allows the support frame to adapt to different clothing styles while maintaining its structural integrity and support capabilities.
Solution Approach 2:
By transitioning to a three-dimensional structure with twisted wire surfaces, the support frame gains the ability to coordinate with outerwear more effectively. The extended vertical portions and twisted surfaces create visual depth and dimension that complement various outerwear styles, particularly low-cut dresses and tops, enhancing the overall aesthetic presentation.
3Shape
If wire surfaces are twisted outwardly at angles, then three-dimensional shape is created, but manufacturing complexity increases
Solution Approach 1:
The twisted wire surfaces are designed with specific curvature radii and twist angles that can be standardized for manufacturing. By establishing consistent geometric parameters for the twists and curves, the complex three-dimensional shape can be reproduced efficiently through standardized fabrication processes, reducing manufacturing complexity while maintaining the desired aesthetic effect.

AI summary
A three-dimensional support frame (1) for the linkage section (also known as "heart") of bra cups for low-cut underwear is disclosed. The support frame (1) comprises a body having a U-shaped support frame. The body of the support frame is made of a wide flat wire; wire surfaces of two vertical portions (2,3) of the body of the support frame being correspondingly twisted outwardly at an angle with respect to a vertical axis, forming an anticlockwise angle of 15°-85° with respect to a horizontal plane, and the twists start at a position (f) of the maximum radius of semicircular lower portion of the U shape. The twisted wire surfaces of the two vertical portions are of an arc-shaped structure which is curved outwardly, an outwardly curved portion with a maximum curvature being offset in a distance of 5mm-50mm with respect to midpoint of a bottom portion of the U-shaped support frame.
