Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal liquid soap dispensers with timers lack a removable and user-interactive timing mechanism that provides visual and audible cues for the recommended hand-washing duration, limiting their versatility and effectiveness in encouraging proper hygiene practices.
Innovation Solution
A removably mounted timer assembly for personal soap dispensers, featuring a housing with a pressure switch, LED, sound generating chip, and speaker, which signals the user audibly and visually during the recommended hand-washing interval, and can be easily installed on various dispensers using a flexible mounting system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the timer mechanism is permanently incorporated into the soap dispenser, then the timing function is reliable, but the adaptability and versatility are reduced
Solution Approach 1:
The timer assembly is divided into a separate removable unit that can be detached from the soap dispenser. This segmentation allows the timer to be removed and transferred between different dispensers, providing versatility while maintaining reliable timing functionality through dedicated timer components.
Solution Approach 2:
The removable timer assembly can be universalized to work with multiple different soap dispenser types. The timer unit with its housing and mounting means can be attached to various dispensers, making it a multi-functional component that enhances adaptability across different products.
2Reliability
If the timer mechanism is permanently incorporated into the soap dispenser, then the timing function is stable, but the ease of operation and user interaction are reduced
Solution Approach 1:
The timer assembly is designed to be self-contained with integrated actuating means that automatically starts the timer when the dispenser is activated. This self-service approach maintains stable timing while improving ease of operation, as users don't need to manually start or stop the timer - it automatically responds to dispensing actions.
Solution Approach 2:
The timer actuating means is merged with the dispenser's existing actuation mechanism. When the user depresses the handle to dispense soap, the same motion simultaneously activates the timer through the pressure switch, combining two functions into one operation and improving ease of use while maintaining timing stability.
3Productivity
If visual and audible signaling means are added to the timer, then the effectiveness in encouraging hand-washing is improved, but the device complexity increases
Solution Approach 1:
The timer replaces purely mechanical timing mechanisms with electronic signaling systems. Instead of relying solely on mechanical countdown indicators, the system uses LED lights and audible tones to signal time intervals, making the timing information more effective and engaging for users while accepting the resulting increase in device complexity.
Solution Approach 2:
The timer assembly incorporates feedback mechanisms through visual (LED) and audible signals that provide real-time information to users about the remaining time. This feedback system enhances the effectiveness of encouraging proper hand-washing duration by keeping users informed and engaged, justifying the added complexity through improved user interaction and hygiene education.
4Adaptability or versatility
If the timer assembly is made removable and transferable, then the adaptability is improved, but the mounting and demounting operation becomes more complex
Solution Approach 1:
The mounting interface is designed with dynamic characteristics, using flexible mouth portions that can adapt to different handle sizes and shapes. The resilient flexibility allows the same timer assembly to be easily attached and detached from various dispenser types while maintaining secure connection during use, balancing adaptability with ease of operation.
Solution Approach 2:
The mounting means incorporates flexible mouth portions made of resilient material that can stretch and conform to different handle geometries. This flexibility enables the timer assembly to be easily mounted on various dispensers without requiring precise fitting, simplifying the mounting and demounting operations while maintaining secure attachment during normal use.

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 timer assembly effectively encourages users to wash their hands for the recommended duration by providing visual and auditory cues, enhancing user interaction and versatility across different soap dispensers.
Implementation Method 1
the actuating means is a pressure switch and the housing caps the handle so that the switch is operated by pressure of the user's hand during depression of the handle to dispense soap
Implementation Method 2
the signaling means comprises an LED and a sound generating chip and speaker operably connected to the timer and battery by an electrical circuit
Implementation Method 3
the signaling means comprises an LED and a sound generating chip and speaker operably connected to the timer and battery by an electrical circuit

AI summary
A timer assembly mounted removably on a personal soap dispenser of a type having a pump operated by a soap dispensing plunger with a handle and spout. The timer assembly has a housing capsule with a timer for measuring a preselected time interval; LEDs and a music generating chip for signaling the time interval to the user, and a pressure switch for starting the timer. The housing capsule is received in a flexible hood/cover mounted on the top of the handle so that pressure switch is actuated to start the time by pressure of the user's hand during depression of the handle to dispense soap.
