Infant Sterilizer Vent Valve for Steam Retention and Fast Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant feeding equipment sterilizers face inefficiencies in energy consumption and water usage due to steam and hot air escaping through vents during sterilization, prolonging heating times and increasing humidity.
Innovation Solution
A valve assembly in the sterilizer that switches between restricting and allowing venting during and after sterilization, retaining steam for efficient sterilization and facilitating rapid drying by venting residual humidity and condensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If vents are provided in the lid to allow residual humidity to escape after sterilizing, then drying speed is improved, but steam and hot air escape during sterilizing resulting in longer heating time and higher energy consumption
Solution Approach 1:
The vent is made dynamically controllable through a valve assembly that can switch between open and closed states. During sterilization, the valve closes to prevent steam escape and energy loss. After sterilization, the valve opens to enable rapid drying by allowing humidity escape. This dynamic control resolves the contradiction by adapting the vent's state to different operational phases.
Solution Approach 2:
The valve assembly is designed to automatically close before sterilization begins and remain closed throughout the process, preventing premature steam escape. After sterilization completes, the valve automatically opens to facilitate drying. This preliminary positioning and automatic switching ensure optimal performance for each phase without manual intervention.
2Speed
If vents are provided in the lid to allow residual humidity to escape after sterilizing, then drying speed is improved, but more water is consumed during sterilizing
Solution Approach 1:
The controllable valve assembly dynamically manages the vent opening based on operational phase. During sterilization, the valve remains closed to prevent steam and water loss. After sterilization, the valve opens to enable rapid evaporation and removal of residual humidity. This dynamic control resolves the contradiction by preventing water loss during sterilization while enabling efficient water removal during drying.
3Speed
If vents are provided in the lid to allow residual humidity to escape after sterilizing, then drying speed is improved, but humidity in the room increases unnecessarily
Solution Approach 1:
The valve assembly provides dynamic control over vent opening. During sterilization, the valve closes to contain steam within the sterilizer, preventing unnecessary humidity buildup in the room. After sterilization, the valve opens to enable drying, but the contained design ensures steam is directed appropriately. This resolves the contradiction by controlling when steam is released to the environment.
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
Enhances energy efficiency and reduces water consumption by retaining steam during sterilization while allowing rapid drying post-sterilization, optimizing sterilization and drying times.
Implementation Method 1
by the valve assembly restricting, e.g. blocking, venting from the chamber via the vent during the steam sterilizing, more of the steam supplied into the chamber may be retained therein during the steam sterilizing
Implementation Method 2
a heating element in a base unit on which the basket is placed vaporizes water and generates hot steam
Implementation Method 3
residual humidity present in the chamber may be vented and/or condensed water on the infant feeding equipment may be allowed to evaporate and escape from the chamber via the vent

AI summary
Provided is an infant feeding equipment-sterilizing apparatus (100). The apparatus comprises a chamber (102, 104) for receiving infant feeding equipment to be steam sterilized. A vent (108) is provided for venting air and/or steam from the chamber, e.g. to atmosphere. A valve assembly (110) restricts venting via the vent during steam sterilizing and allows venting from the chamber via the vent following the steam sterilizing. The venting being allowed following the steam sterilizing may assist to dry the infant feeding equipment following the steam sterilizing. However, by the valve assembly restricting, e.g. blocking, venting from the chamber via the vent during steam sterilizing, more of the steam supplied into the chamber can be retained therein during the steam sterilizing, thereby assisting to make the steam sterilization more energy efficient. Further provided is a chamber wall portion, e.g. lid, for an infant feeding equipment-sterilizing apparatus, and a method for sterilizing infant feeding equipment using such an apparatus.
