Solution Overview

Problem

Elderly individuals and susceptible persons are at risk of fatal drowning in bathtubs due to fainting and inability to recover consciousness, as existing safety measures are inadequate in preventing water ingress and alerting authorities in time.

Innovation Solution

A safety bath plug device with a cone and pedal-like units that automatically drains water when the user becomes unconscious, and an electric version connected to a tilt sensor and home security system to alert services, along with a shower fall prevention system using a rod and cushion to stabilize the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional bath plug is used, then the drain pipe is sealed to prevent water leakage, but the user cannot be alerted when fainting and water cannot be drained automatically

Engineering Contradiction:
Improvedrowning preventionVSAvoidplug structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention combines the bath plug function with an alarm system and automatic drainage capability into a single integrated device. The plug unit includes both the sealing component and the alarm sensor, merging multiple safety functions (sealing, detection, alerting, and drainage activation) into one device to improve drowning prevention without requiring multiple separate components

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bath plug is designed to automatically detect when the user has fainted through sensors that monitor movement or pressure changes, automatically trigger the alarm, and automatically activate the drainage system without requiring manual intervention. This self-service capability ensures continuous protection even when the user is unconscious

Inventive Principle:
Principle #25Self-service

2Reliability

If the bath plug remains sealed during fainting, then water stays in the tub, but the user may drown if unconsciousness persists

Engineering Contradiction:
Improvesurvival chanceVSAvoidresponse time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The alarm system is pre-configured to immediately activate upon detecting fainting symptoms, and the automatic drainage system is pre-programmed to start draining water simultaneously with the alarm activation. This preliminary preparation ensures that help is alerted and water begins draining within seconds of the incident, maximizing survival chances by minimizing response time

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the user's state through sensors and provides immediate feedback by triggering the alarm and drainage system when abnormal conditions (such as lack of movement or pressure changes indicating fainting) are detected. This real-time feedback mechanism ensures rapid response to drowning risks

Inventive Principle:
Principle #23Feedback

3Ease of operation

If pedal-like units are added to the bath plug, then the plug can be easily dislodged during distress, but the device structure becomes more complex

Engineering Contradiction:
Improveplug dislodgingVSAvoidplug structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pedal-like units are positioned and designed to be automatically activated by the user's body movements during fainting or distress, such as leg movements or body sliding. The units require minimal force to trigger and work passively with the user's natural movements, providing easy operation during emergencies without requiring complex control mechanisms

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The bath plug is divided into functional segments: the sealing component, the pedal-like activation units, and the alarm/drainage system. This segmentation allows each component to perform its specific function independently while maintaining overall system simplicity, with the pedal units serving as a separate, easily activated mechanism for dislodging the plug

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Increases chances of survival by draining water and alerting authorities promptly, while the shower fall prevention system minimizes injuries by stabilizing the user during falls.

Implementation Method 1

the bath plug device has an overall density which is slightly below the density of water such that the bath plug device starts to float as soon it is detached from the drain pipe

Methodology Applied
Scientific EffectBuoyancy: Archimedes' Principle (Buoyancy)

Implementation Method 2

a tilt sensor is fixed inside the protrusion, which in turn is wirelessly connected to a bath security switch and/or a house server

Methodology Applied
Scientific EffectTilt sensing: Accelerometer
