Wireless Brassiere with Pocket Cups and Cantilever Back
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bras, especially those without underwires, fail to securely hold breasts in place, particularly when the lower breast mass is below the breast crease line, leading to discomfort and instability due to tight straps, buckling closures, and uneven weight distribution, which causes the back to creep up between the shoulder blades.
Innovation Solution
A wireless, front-closure brassiere design featuring inner 'pocket' cups that distribute the breast weight, a crisscross back with cantilever effect, and four-way stretch fabric with elastic elements to prevent upward creep and eliminate the need for tight straps, combined with a keyhole zipper for easy closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If tight straps and wires are used to keep breasts in place, then breast stability is improved, but comfort deteriorates due to skin poking and dent creation
Solution Approach 1:
The patent removes the underwire component entirely, extracting the harmful element that causes skin poking while maintaining breast stability through alternative means including the pocket cup design and strategic elastic placement
Solution Approach 2:
The patent applies elastic material specifically at strategic locations where breast weight creates tension, providing localized support and stability without requiring widespread tight straps or wires that cause discomfort
2Ease of operation
If back-located hook and eye closures are used, then ease of operation is improved, but comfort deteriorates due to bending and poking under breast weight
Solution Approach 1:
The patent inverts the traditional closure location by moving from back-located to front-located closures, placing the zipper and hook-eye mechanism at the front center where it is not subjected to bending forces from breast weight, thereby maintaining ease of operation while eliminating the poking problem
3Ease of operation
If front zipper closures are used, then ease of operation is improved, but stability deteriorates due to buckling from breast curvature
Solution Approach 1:
The patent segments the closure system into two functional parts: a front zipper for ease of operation and a separate hook-eye closure at the back for stability, allowing each component to perform its optimal function without interfering with the other
Solution Approach 2:
The patent addresses the buckling issue by adding vertical dimension to the closure system with the hook-eye component that extends from the front, creating a multi-dimensional closure structure that accommodates breast curvature while maintaining zipper functionality
4Ease of manufacture
If static or minimal stretch fabric is used, then manufacturing simplicity is improved, but adaptability deteriorates as fabric does not move with the body
Solution Approach 1:
The patent changes the fabric parameter from static to four-way stretch, enabling the material to expand and contract in multiple directions to accommodate body movement and breast motion while maintaining structural integrity and support
5Object-affected harmful factors
If traditional bras without wires are used, then comfort is improved, but breast stability deteriorates as breasts do not stay in cups
Solution Approach 1:
The patent creates a nested structure where a pocket cup is placed inside the main bra cup, providing an additional containment layer that secures the breast in place without requiring wires, thereby maintaining comfort while improving stability
6Ease of manufacture
If the back of the bra is designed simply, then manufacturing simplicity is improved, but stability deteriorates as the back creeps up between shoulder blades
Solution Approach 1:
The patent introduces dynamic elements to the back structure through crisscrossing straps and gathering fabric that can adapt and redistribute tension as the wearer moves, preventing the back from creping up while maintaining relative simplicity
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 effectively keeps breasts stable and separated, prevents buckling, and distributes weight evenly, eliminating the need for tight straps and reducing discomfort, while allowing for a snug, natural fit without constriction.
Implementation Method 1
four-way stretch fabric with elastic elements to prevent upward creep
Implementation Method 2
The two pieces that cross in the back of the brassiere have tension points that facilitate a cantilever effect
Implementation Method 3
contain the overhang or lower breast mass that is below the breast crease line on the chest therein
Implementation Method 4
distribute the breast weight evenly

AI summary
A brassiere designed to effectuate a stabilizing effect through the use of inner pockets along each bra cup held in place by the weight of breast overhang especially when the lower breast mass is below the breast crease line on the chest while simultaneously producing a stabilizing effect by way of rear pieces that distribute the breast weight from front to back to effectuate a cantilevering effect to diametrically opposing locations along a lower band adjacent to the lateral portions of the wearer's rib cage. Another component of the brassiere also distributes tension in the rear of the brassiere in a countervailing manner toward the band adjacent the spine of the wearer.
