Solution Overview

Problem

Individuals, especially children, often struggle with proper hand washing techniques and duration, leading to the spread of germs and infections due to lack of engagement and awareness of proper hygiene practices.

Innovation Solution

A motion-activated, timed LED illuminated soap bar that senses changes in surroundings, such as motion or temperature, to provide visual cues and illuminate for a predetermined time, guiding users through the hand washing process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a bar of soap is made to illuminate with light sources and sensors, then hand washing engagement and education is enhanced, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improvehand washing engagementVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple functional components (soap dispenser, LED light sources, sensors, circuit board, battery) into a single integrated bar of soap unit. This merging approach maintains the engaging illuminated hand-washing function while consolidating complexity into one compact device that users interact with as a single object.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The bar of soap serves multiple functions simultaneously: it dispenses soap, provides illumination through LED lights, detects user presence via sensors, and guides hand-washing duration. This multi-functionality enhances engagement while avoiding the need for separate devices for each function.

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

2Ease of operation

If a bar of soap includes electronic components like light sources and sensors, then visual incentives are provided to encourage proper hand washing, but manufacturing cost increases

Engineering Contradiction:
Improvevisual incentive provisionVSAvoidmanufacturing cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The bar of soap with electronic components is designed as a disposable item that is discarded after use. This approach justifies the higher manufacturing cost by eliminating the need for expensive durability and long-term maintenance, as the entire unit is replaced rather than repaired.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The bar of soap contains an integrated battery and electronic circuit that automatically powers the light sources and sensors without requiring external power connections or complex manufacturing assembly. This self-contained design simplifies manufacturing while providing the visual incentive function.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If the bar of soap uses motion sensors and light sources, then proper hand washing duration is ensured, but energy consumption increases

Engineering Contradiction:
Improvehand washing duration measurementVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The light sources in the bar of soap are activated periodically based on sensor detection of hand placement, rather than remaining continuously illuminated. The lights turn on when hands are detected and turn off after a predetermined time interval, reducing overall energy consumption while maintaining accurate duration measurement for hand-washing guidance.

Inventive Principle:
Principle #19Periodic action
