Solution Overview

Problem

Existing wearable devices fail to provide a seamless integration of physiological sensors into garments, such as sports bras, due to space constraints and the need for specialized electronics knowledge, leading to manufacturing complexity and recycling challenges.

Innovation Solution

A bra design with integrated physiological signal measurement components, including electrodes and conductive leads, arranged on a side wing, allowing easy integration and manufacturing without specialized electronics knowledge, and enabling easy recycling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electrodes and electronic components are integrated into the bra structure at manufacturing stage, then physiological signal measurement capability is achieved, but manufacturing complexity increases and requires specialized electronics knowledge

Engineering Contradiction:
Improvephysiological signal measurement capabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The bra is divided into functional modules: front portions with cups, side wings with elastic underbands, and back portions. Electronic components are integrated specifically into the side wing module rather than distributed throughout the entire garment, simplifying the manufacturing process while maintaining measurement capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The side wing module serves multiple functions: it provides structural support as part of the bra, contains the elastic underband for comfort, and integrates electrodes and electronic components for physiological signal measurement. This multi-functionality reduces the need for separate dedicated measurement components

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If electronic components are integrated into the bra structure, then physiological signal measurement is enabled, but recycling difficulty increases due to mixed materials

Engineering Contradiction:
Improvephysiological signal measurement capabilityVSAvoidrecycling ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

By concentrating all electronic components within the removable side wing module, the design enables easy separation of electronic materials from textile materials during recycling. The module can be detached and sent to specialized e-waste recycling facilities while the bra fabric can be recycled separately

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The side wing module is designed as a discrete unit that can be easily removed and sent for specialized recycling. This allows electronic components to be recovered and processed through appropriate e-waste channels while the textile portion can be recycled through textile recycling programs

Inventive Principle:
Principle #34Discarding and recovering

3Ease of operation

If fabric under cups is minimized for skin-tight comfort, then user comfort is improved, but space for electrodes and sensor packages is reduced

Engineering Contradiction:
Improveuser comfortVSAvoidspace for electrodes
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

Instead of placing electrodes under the cups in the traditional horizontal plane, the design moves electrodes to the side wings, utilizing the vertical and lateral dimensions of the bra structure. This provides adequate space for electrodes while maintaining the skin-tight fit under the cups

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
