Motorized Wiping Solution Nozzle for Uniform Toilet Tissue Wetting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable bathroom wipes cause plumbing issues due to their weight and slow biodegradability, and existing dispensers are inconvenient and prone to cross-contamination.
Innovation Solution
A touchless, motorized wiping solution dispenser that activates a wide band of solution onto toilet tissue using a motion sensor, eliminating the need for disposable wipes by integrating a nozzle mechanism with a closure feature and a puncture feature for solution flow, and optionally including payment and communication features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable bathroom wipes are used for cleaning, then cleaning effectiveness is improved, but plumbing reliability deteriorates due to slow biodegradability and heavy weight
Solution Approach 1:
The invention separates the cleaning solution from the tissue substrate. The dispenser applies liquid cleaning solution to dry toilet paper, creating a wet wipe effect without using pre-soaked disposable wipes. This segmentation allows the tissue to remain lightweight and biodegradable while still providing effective cleaning through the applied solution.
Solution Approach 2:
The invention uses liquid cleaning solution as an intermediary substance between the user and the tissue. Instead of relying on pre-treated disposable wipes, the system mediates the cleaning process by applying solution to standard toilet paper, achieving effective cleaning while avoiding plumbing issues associated with disposable wipes.
2Ease of operation
If wipes are placed in pop-up containers for dispensing, then ease of operation is improved, but hygiene deteriorates due to cross-contamination from touching the container
Solution Approach 1:
The invention replaces manual mechanical retrieval of wipes with an automated dispensing system. A motorized mechanism with a nozzle automatically applies cleaning solution to toilet paper, eliminating the need for users to manually reach into and touch the container to retrieve wipes or tissue.
Solution Approach 2:
The dispenser system performs the cleaning preparation automatically without user intervention. The motorized nozzle applies solution to the tissue, and the closure mechanism automatically seals the dispensing area, allowing the system to serve itself and the user without requiring the user to touch or open the container.
3Manufacturing precision
If a motorized nozzle mechanism is used to dispense solution, then manufacturing precision is improved for uniform coverage, but device complexity increases
Solution Approach 1:
The motorized nozzle operates through periodic reciprocating motion, moving back and forth across the toilet paper to apply solution uniformly. This periodic action ensures even distribution of the cleaning solution across the entire surface area of the tissue.
Solution Approach 2:
The closure feature acts as an intermediary element that simplifies the motorized mechanism. It seals the nozzle opening at the ends of the reciprocating stroke, preventing solution leakage and eliminating the need for complex sealing mechanisms, thereby reducing overall device complexity while maintaining precision.

AI summary
A wiping solution dispenser utilizes a motorized dispenser mechanism that moves a nozzle back and forth along a stroke to dispense a wide band of wiping solution onto toilet tissue. A motor may be coupled with a nozzle that moves back and forth or rotates about a pivot point to dispense a band of wiping solution. Wiping solution may be within a solution container that is configured for insertion into the dispenser housing and may be automatically ruptured by a puncture feature. A pump may force the wiping solution from the nozzle, or the solution may be gravity fed. A motion detector may be incorporated to control the actuation and dispensing of the solution. A near field communication transceiver may be used to receive payment before solution is dispensed.
