Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bra sizing methods are inconsistent and complex, relying on mathematical equations and indirect measurements, which can lead to consumer confusion and poorly fitting bras.
Innovation Solution
A non-customized standard array of bras is constructed using a grading array based on scanned body data, with bands and cup placements defined by constant angular positions and volumes, ensuring a consistent fit across a wide range of body types without individual customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional bra sizing methods using mathematical equations and indirect measurements are used, then bra size can be determined, but consumer confusion and poor fit occur due to inconsistency and complexity
Solution Approach 1:
The patent changes the measurement parameters from indirect mathematical calculations to direct physical measurements. Specifically, it uses direct underbust circumference measurement and direct breast volume measurement (via water displacement method) to determine bra size, replacing the traditional indirect method that uses tape measurements and mathematical equations. This direct measurement approach eliminates consumer confusion while maintaining accuracy.
Solution Approach 2:
The patent replaces the mechanical/mathematical calculation system with a physical measurement system. Instead of using tape measurements and mathematical equations to calculate bra size, it uses direct physical measurement of underbust circumference and breast volume (through water displacement), providing a more intuitive and accurate sizing method.
2Manufacturing precision
If individually customized brassieres based on specific consumer measurements are provided, then perfect fit is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent changes the approach from full individual customization to standardized sizing based on key physical parameters. It uses direct measurement of underbust circumference and breast volume to categorize consumers into standard size groups, allowing mass production of bras that fit specific measurement ranges while maintaining good fit without individual customization complexity.
Solution Approach 2:
The patent creates a universal sizing system that can accommodate a wide range of consumers through standardized size categories. The bra design incorporates adjustable features (such as adjustable straps and hooks) that allow a single standardized bra model to fit multiple body types within a size category, reducing manufacturing complexity while maintaining versatility.
3Stability of the object's composition
If consistent cup volume across different band lengths is implemented, then sizing consistency improves, but traditional sizing conventions are disrupted
Solution Approach 1:
The patent changes the cup sizing parameter from traditional letter designations (A, B, C, etc.) to volume-based measurement (cubic centimeters). This allows consistent cup volume across different band lengths, as cup size is directly tied to breast volume measurement rather than being relative to band size. For example, a 400cc cup maintains the same volume regardless of whether it's on a 30-inch or 36-inch band.
Solution Approach 2:
The patent creates a new sizing model that copies the physical reality of breast volume rather than relying on traditional relative sizing conventions. By measuring actual breast volume through water displacement and using that direct measurement to determine cup size, it creates a sizing system that accurately reflects physical dimensions without being constrained by historical sizing conventions.

AI summary
A non-customized standard array of brassieres generated from a grading array including a number of differently-sized bands that each defines an arc. The grading array defines a constant angular band end location across a plurality of band lengths, defines a constant angular cup location for different-sized cups on a single band length as well as for the same or different-sized cups across a plurality of band lengths, and defines a variable bridge distance that varies based on cup size. The non-customized, standard array of brassieres is identifiable by a standard brassiere measuring system where the volume identifier of the cup represents a consistent volume regardless of the band length for which the cup is associated. Further, the standard brassiere measuring system is based on direct body measurements representative of breast volume and underbust circumference.
