Hand Soap Dispenser with Rolling Ball Timer for 20-Second Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many individuals, including children and adults, find it challenging to wash their hands for the recommended 20 seconds, leading to inadequate hand hygiene and increased risk of infection, as conventional methods like counting or singing require additional mental effort and are perceived as laborious.
Innovation Solution
A soap dispenser integrated with a 'rolling ball timer' that visually, audibly, or vibratorily signals when 20 seconds have passed, alleviating the user's perception of time and promoting compliance with proper hand-washing techniques by providing positive feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods like counting or singing are used to promote hand washing duration, then hand washing compliance is improved, but mental effort and perceived labor increase
Solution Approach 1:
The timer device serves itself by automatically tracking and displaying the hand washing duration without requiring user intervention. The visual display and audio signals autonomously provide feedback to the user, eliminating the need for mental counting or singing while maintaining compliance reliability.
Solution Approach 2:
The patent replaces the mechanical/mental system of counting or singing with an electronic timer system that uses visual displays and audio signals to track and communicate hand washing duration, thereby reducing mental effort while maintaining compliance.
2Reliability
If hand washing duration is extended to 20 seconds, then hygiene effectiveness is improved, but user perception of time increases making the task seem more laborious
Solution Approach 1:
The timer provides continuous visual and audio feedback to the user during hand washing, showing exactly how much time has elapsed and when the full 20 seconds has been reached. This feedback mechanism helps users perceive the passage of time more accurately and reduces the feeling that 20 seconds is excessively long, thereby maintaining hygiene effectiveness while improving user acceptance.
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
The soap dispenser with a rolling ball timer simplifies hand-washing duration compliance, reducing mental effort and enhancing the experience, thereby encouraging users to wash their hands for the full recommended time, thus improving hygiene and infection prevention.
Implementation Method 1
The timer can include any suitable visual, audio, and/or vibratory signal(s) to indicate to the user a passage of the predetermined duration. For example, the traveling object may be opaque and/or colored and the timer includes a transparent enclosure. In this example, the user can visually watch the traveling object move through and reach the end of the track.

AI summary
A liquid soap dispensing device with a soap dispensing apparatus and a timer, and associated methods, are disclosed herein. The soap dispensing apparatus includes a housing and a soap dispensing element. The timer includes a traveling object (e.g., a ball), a track, and a mover. The track is configured to receive the traveling object at a start position and release the traveling object at an end position. The track is also configured to carry the traveling object from the start position to the end position in a time interval. The mover is configured to displace the traveling object from a first position to a second position. Displacement of the traveling object from the first position to the second position initiates the release of the traveling object onto the track at the start position.
