Solution Overview

Problem

Existing breast self-examination training devices are not designed for daily use in the routine of women in low- and middle-income populations, lacking integration into daily activities and privacy moments, thus failing to establish a habit of regular self-examination.

Innovation Solution

A training device comprising a flexible silicone breast model filled with viscous fluid, simulating abnormal tissues, which can be used during routine activities like showering, allowing direct practice and habit formation through a simulator that transfers fluid to the skin for real self-examination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a breast training device is designed for exclusive training use, then it can provide specialized training functionality, but it cannot be integrated into daily routine activities

Engineering Contradiction:
Improvetraining effectivenessVSAvoidintegration into daily routine
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The device combines breast training simulation with showering functionality, allowing it to serve both as a training tool and a daily hygiene accessory. The breast model can be used for palpation training during showering, eliminating the need for separate training sessions and integrating the device into the woman's daily routine.

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

Solution Approach 2:

The patent merges the breast training model with showering equipment by incorporating a water reservoir and spray system. The breast model is positioned to receive water spray during showering, combining the training function with the daily hygiene activity of showering, thereby increasing usage frequency and habit formation.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If a breast training device is placed in visible locations like bathrooms, then it can be seen daily, but it may not be used regularly due to lack of privacy or convenience

Engineering Contradiction:
Improvevisibility and accessibilityVSAvoidprivacy and convenience of use
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The device is merged with the showering process itself, which is a private activity. By positioning the breast model to be used during showering when the woman is already in a private state, the device gains both visibility (in the bathroom) and convenience of use (during a private moment), resolving the contradiction between visibility and privacy.

Inventive Principle:
Principle #5Merging (Combining)

3Measurement precision

If breast self-examination is taught as a separate training activity, then proper technique can be learned, but it becomes an additional time commitment that reduces adherence

Engineering Contradiction:
Improvepalpation technique accuracyVSAvoidtime required for training and examination
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent combines breast palpation training with the existing daily showering routine. The breast model is positioned in the shower area and can be palpated while the woman is showering, thereby merging two activities into one time slot. This eliminates the need for separate training sessions and reduces the total time commitment while maintaining technique accuracy through the training model.

Inventive Principle:
Principle #5Merging (Combining)
