Wet Wipe Container Spray Pump to Prevent Heating Dry-Out
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby wipe warmers cause moisture evaporation and discoloration of wipes due to heating, which compromises their effectiveness and intended use.
Innovation Solution
A baby wipe warmer with a fluid pump dispenser that maintains humidity by spraying a moisturizing fluid directly onto the wipes, even when the container is heated, using a spray pump mechanism integrated into the housing and a resilient lid seal to prevent air and moisture loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heating element is added to warm the wipes, then comfort for infant is improved, but moisture evaporates and wipes discolor
Solution Approach 1:
The spray pump dispenses moisturizing fluid onto the wipes before heating occurs, pre-saturating the wipes with moisture. This preliminary action ensures that the wipes maintain adequate moisture levels even as the heating element operates, preventing both evaporation-related dryness and discoloration
Solution Approach 2:
The system maintains continuous operation of both the heating element and spray pump, ensuring that warmth and moisture are simultaneously provided to the wipes. This continuous dual action ensures that as moisture begins to evaporate from heating, it is immediately replenished by the spray pump, maintaining optimal wipe conditions
2Temperature
If heating element is added to warm the wipes, then comfort for infant is improved, but wipe discoloration occurs
Solution Approach 1:
The spray pump applies moisturizing fluid to the wipes before the heating process begins, establishing a protective moisture barrier. This preliminary saturation prevents the wipes from undergoing thermal discoloration by ensuring they maintain proper hydration levels throughout the heating process
Solution Approach 2:
The system converts the potentially harmful effect of heat (which causes discoloration) into a beneficial outcome by simultaneously using that heat to evaporate excess moisture while the spray pump replenishes it. This controlled cycle prevents discoloration by maintaining optimal moisture levels throughout heating
3Reliability
If spray pump is integrated into closed container, then moisture is maintained, but device complexity increases
Solution Approach 1:
The spray pump mechanism is integrated directly into the container housing, combining the storage function and moisture application function in a single unified structure. This merging eliminates the need for separate external spraying devices and reduces overall system complexity while maintaining reliable moisture delivery
Solution Approach 2:
The container housing serves multiple functions: it stores the wipes, contains the heating element, houses the spray pump mechanism, and provides the structural framework. This multi-functionality reduces the number of separate components needed, thereby reducing overall device complexity while maintaining moisture maintenance capability
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 solution ensures that wipes remain moist and prevent discoloration, maintaining their effectiveness and comfort for infants even when heated, by continuously providing moisture and preventing evaporation.
Implementation Method 1
Many of these warming elements are electrically operated. However, adding the warmth to the wipe container inherently affects the intended use of the wipe warmer and the wipes contained therein, in that the heat causes the moisture in the wipes to evaporate.
Implementation Method 2
A baby wipe warmer with a fluid pump dispenser that maintains humidity by spraying a moisturizing fluid directly onto the wipes
Implementation Method 3
the heat causes the moisture in the wipes to evaporate. Heating the wipes also causes an undesirable discoloration to the wipe.

AI summary
A wet wipe container having a housing having an internal compartment for holding wet wipes, a lid and a moisturizing spray dispenser. The lid has a dispensing opening through which wipes are dispensed and a dispensing opening lid for covering the dispensing opening while not in use. The moisturizing spray dispenser has an outlet positioned to dispense fluid directly onto the wet wipes in a storage position in the housing.
