Moistened wipes dispensing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies have not addressed the need for a device that can automatically dispense and warm a moistened wipe that includes a motion sensor and a heating element for warming the wipe upon dispensing, while also providing a manual backup mechanism for hands-free operation.
Innovation Solution
A stand with a dispensing unit elevated for accessibility, equipped with a motion sensor to actuate dispensing and a heating element to warm the wipe, and a manual dispensing mechanism for backup operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an automated dispensing unit with motion sensor is used, then hands-free operation and germ transmission reduction are achieved, but device complexity increases
Solution Approach 1:
The patent replaces manual mechanical operation with an automated motion-sensing system. The motion sensor detects user approach and automatically triggers the dispensing mechanism, eliminating the need for hands-free contact with the dispenser while reducing germ transmission risk.
Solution Approach 2:
The dispensing system performs the dispensing action automatically without requiring user intervention. The system senses motion and self-actuates to dispense the wipe, making the system serve itself rather than requiring manual operation.
2Ease of operation
If a heating element is added to warm the wipe, then user comfort is enhanced, but device complexity and energy consumption increase
Solution Approach 1:
The heating element pre-warms the wipe before dispensing. By applying heat in advance to the wipe stored in the dispensing unit, the system ensures the wipe is already at a comfortable temperature when dispensed, enhancing user comfort without requiring post-dispensing heating.
Solution Approach 2:
The heating element applies thermal energy locally to the wipe material itself rather than heating a large volume of air or the entire dispensing unit. This targeted heating approach minimizes energy consumption while effectively warming the specific area that contacts the user.
3Ease of operation
If the dispensing unit is elevated on a stand, then accessibility is improved, but device complexity increases
Solution Approach 1:
The system is divided into separate functional components: a standalone dispensing unit and a support stand. This segmentation allows the dispensing mechanism to be elevated to an accessible height while keeping the base structure simple and stable, reducing overall system complexity.
Solution Approach 2:
The stand acts as an intermediary structure that supports the dispensing unit at an elevated position. This mediator component provides the necessary height for accessibility without requiring the dispensing unit itself to be structurally complex, separating the support function from the dispensing function.
4Reliability
If a manual dispensing mechanism is included as backup, then reliability is improved, but device complexity increases
Solution Approach 1:
A manual dispensing mechanism is incorporated as a backup system to cushion against failures of the automated motion-sensing system. This redundant mechanism ensures that wipe dispensing can still occur if the electronic sensors or actuators malfunction, improving system reliability.
Solution Approach 2:
The system can operate in different modes or parameter states: automated mode under normal conditions and manual mode when automated functions fail. This ability to change operational parameters ensures continuous functionality while maintaining relatively simple mechanical components for the manual backup.
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
Enables hands-free dispensing of warmed moistened wipes, reducing germ transmission and enhancing user comfort, with a backup mechanism for reliability.
Implementation Method 1
The dispensing unit has a motion sensing element which actuates the dispensing unit to dispense one of the moistened wipes when the motion sensing element senses motion
Implementation Method 2
A dispensing unit is attached to the stanchion... equipped with a motion sensor to actuate dispensing and a heating element to warm the wipe

AI summary
A moistened wipes dispensing device includes a stand which includes a base and a stanchion. A dispensing unit is attached to the stanchion such that the dispensing unit is elevated above a support surface to be accessible to a user. The dispensing unit contains a roll of moistened wipes and the dispensing unit has a motion sensing element which actuates the dispensing unit to dispense one of the moistened wipes when the motion sensing element senses motion. Thus, the dispensing unit dispenses one of the moistened wipes when the user approaches the dispensing unit. A dispensing mechanism is movably integrated into the stand which can be manipulated by the user to dispense one of the roll of moistened wipes in the event that the dispensing unit is not operational and will not dispense one of the roll of moistened wipes.
