Solution Overview

Problem

The embarrassment and discomfort caused by hearing bodily function sounds in close living quarters or shared bathroom spaces necessitates a method to anonymize these sounds, allowing individuals to use restrooms with increased confidence and freedom.

Innovation Solution

A device, referred to as a bodily function sound anonymizer, which records and replays sounds using a central processing unit, microphone, and speaker, utilizing motion sensors and algorithms to distinguish and anonymize bodily function sounds, allowing users to share and customize their experience through wireless connectivity and external interfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bodily function sounds are recorded and replayed through a speaker system, then user privacy and confidence are improved, but device complexity increases due to multiple sensors and processing components

Engineering Contradiction:

Improveuser privacyVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system divides the bathroom into multiple detection zones using motion sensors positioned at different locations. Each sensor monitors specific areas (toilet, shower, sink) independently, allowing the system to determine which zone requires sound anonymization. This segmentation reduces the need for a single complex omnidirectional system while maintaining comprehensive coverage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system uses motion sensors as intermediary detection devices that trigger the sound anonymization process. Rather than directly analyzing bodily function sounds, the motion sensors detect user presence and activity patterns, serving as intermediaries that initiate the appropriate anonymization response without requiring direct acoustic analysis.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If motion sensors and algorithms are used to distinguish bodily function sounds, then anonymization accuracy is improved, but device complexity and energy consumption increase

Engineering Contradiction:

Improveanonymization accuracyVSAvoidenergy consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system employs periodic motion detection scanning rather than continuous audio analysis. Motion sensors periodically check for user presence and activity in different bathroom zones, triggering sound anonymization only when motion is detected. This periodic approach significantly reduces energy consumption compared to continuous processing while maintaining accurate detection of when anonymization is needed.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system automatically detects user presence and activity patterns through motion sensors, self-determining when bodily function sounds are likely occurring without requiring manual input or complex real-time audio analysis. The motion detection data itself serves as the trigger mechanism, eliminating the need for separate complex audio classification algorithms.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If sound anonymization is implemented in shared bathroom spaces, then user confidence and freedom are improved, but embarrassment and discomfort persist for some users

Engineering Contradiction:

Improveuser confidenceVSAvoidembarrassment

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system proactively anonymizes sounds before they can be heard by others in the bathroom. By detecting motion patterns that indicate bodily functions are occurring and immediately triggering sound playback through speakers, the system prevents embarrassing sounds from propagating through the space, thereby eliminating the source of embarrassment rather than merely masking it.

Inventive Principle:

Principle #9Preliminary anti-action
