Wire-Free Push-Up Bra Hinge for Support Across Breast Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire-free push-up brassieres fail to provide adequate support and flexibility across a range of breast sizes, particularly for fuller-bodied women.
Innovation Solution
A wire-free push-up brassiere with a hinge that extends along the bottom edge of the padded cups, formed by a stabilizing channel defined by a flexible cord and a top edge of a cradle, offering both rigidity and flexibility to accommodate varying breast sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wire-free brassiere design is used, then comfort is improved, but support is worsened
Solution Approach 1:
The patent employs a flexible cord running along the bottom edge of the cups and a wire casing at the top portion of the cradle to provide structural support without rigid wires. These flexible elements maintain comfort while delivering necessary support through strategic placement and material selection.
Solution Approach 2:
The hinge mechanism allows dynamic adjustment of the cradle's position and shape, enabling the brassiere to adapt its support parameters to different breast sizes and weights. This transforms the static wire-free design into a dynamic support system that maintains effectiveness across various body types.
2Ease of manufacture
If fixed cup structure is used, then manufacturing simplicity is improved, but adaptability to different breast sizes is worsened
Solution Approach 1:
The hinge connecting the cups to the cradle enables dynamic adjustment, allowing the cradle to expand or contract vertically based on breast size. This dynamic mechanism maintains a simple fixed cup structure while providing adaptability through the movable cradle component.
Solution Approach 2:
The brassiere is divided into separate functional components: fixed cups, a flexible cord, a hinged connection, and an adjustable cradle. This segmentation allows the cups to remain simple for manufacturing while the hinged cradle provides the necessary adaptability.
3Strength
If hinge is made rigid, then support is improved, but flexibility to accommodate different breast sizes is worsened
Solution Approach 1:
The hinge is constructed using flexible materials including a flexible cord and wire casing that provide structural support while maintaining flexibility. These materials enable the hinge to offer support for larger breast sizes while still accommodating smaller sizes through elastic deformation.
Solution Approach 2:
The hinge material properties are selected to provide optimal balance between rigidity and flexibility, allowing the structure to maintain support strength while adapting its shape and position to accommodate varying breast sizes and weights.

AI summary
Embodiments of the disclosed technology relate to wire-free push-up brassieres having the versatility to provide enhanced lift, support, and comfort across a range of breast sizes. A wire-free push-up brassiere disclosed herein includes a hinge that extends along a bottom edge of the padded portions of cups of the brassiere. The hinge may be a stabilizing channel formed between the bottom edge of the padded cup portions and a top edge of the cradle. The hinge may be formed of a stabilizing material that provides the hinge with both rigidity and flexibility. In particular, the stabilizing material may impart a rigidity to the hinge that reinforces the breast support provided by the cups, thereby enhancing the push-up characteristics of the brassiere. At the same time, the stabilizing material may have enough flexibility to allow the hinge to accommodate a range of breast sizes.
