Solution Overview
Problem
Current bra-fit analysis in the apparel industry relies on human fit models, which are prone to human error and lack precision, especially in determining the fit of bras, as they are typically designed in static positions and assessed through observation and wearer qualification.
Innovation Solution
A prosthetic torso simulation system featuring a lattice network support structure and synthetic skin made of silicone or ballistic gel, with embedded silicone tubing for pressure sensing, designed to mimic human torso movement and breast dynamics, allowing for precise analysis of bra fit and comfort through data-driven feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If human fit models are used for bra-fit analysis, then the process is simple and easy to operate, but measurement precision and reliability are reduced due to human error
Solution Approach 1:
The patent creates a prosthetic torso that copies the essential anatomical features and movement characteristics of a human torso, replacing human fit models with a controllable replica. This allows precise measurement of bra fit parameters without human variability, while maintaining the simplicity of working with a physical model.
Solution Approach 2:
The patent replaces the human biological system with a mechanical prosthetic torso that can be actuated to simulate human movements. This substitution enables objective, repeatable measurements of bra fit under various movement conditions, eliminating human error while preserving the practical advantages of physical testing.
2Device complexity
If static position analysis is used for bra design, then the process is simple, but adaptability to dynamic movements is reduced
Solution Approach 1:
The patent transforms the static prosthetic torso into a dynamic system by incorporating actuators that can move the torso and synthetic breasts through various positions and movements. This allows the system to adapt to different dynamic conditions (walking, running, jumping) while maintaining the simplicity of a physical model setup.
Solution Approach 2:
The prosthetic torso is designed to perform multiple functions: it can be positioned in various static configurations and also executed dynamic movements. The actuator assembly enables the same physical model to test bra fit across multiple movement types, increasing versatility without requiring multiple specialized devices.
3Ease of operation
If observation and wearer qualification methods are used, then the assessment process is simple, but measurement precision and objectivity are reduced
Solution Approach 1:
The patent incorporates sensors within the prosthetic torso and bra prototypes to automatically collect data on fit parameters, pressures, and movements. This feedback system provides objective, quantifiable measurements that improve reliability and consistency of fit assessment, while the data can be easily analyzed to guide design decisions.

AI summary
A sensor apparatus includes a mannequin to emulate a human body part. The mannequin includes a core that emulates flexibility of a substantially inflexible skeletal portion of the body part, and a pliant covering. The pliant covering includes a pliant three-dimensional surface that emulates contours of an epidermis of the body part, and at least one pliant three-dimensional interior portion to emulate resiliency of a pliant portion of the body part. At least one pressure sensor is arranged between the three-dimensional surface and the core to sense pressure applied against the pliant three-dimensional surface.
