Rotating Steam Nozzle for Feeding Bottle Sterilizer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current feeding-bottle sterilizers face issues with incomplete sterilization and long sterilization times due to inefficient steam distribution and unstable positioning of bottles and nipples, leading to non-thorough sterilization.
Innovation Solution
A feeding-bottle sterilizer design featuring a steam supply device with a rotatable steam nozzle, stretchable steam pipes, and a baffle system that ensures even steam distribution and rapid filling of the sterilization space, along with a removable and adjustable holder to prevent steam pipes from contacting the inner bottle wall, facilitating thorough and quick sterilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple container structure with heating device is used, then the device complexity is reduced, but the sterilization time increases and sterilization completeness deteriorates
Solution Approach 1:
The sterilizer is divided into multiple functional components: a steam generation system, a rotatable steam nozzle for external sterilization, and stretchable steam pipes for internal sterilization. This segmentation allows simultaneous multi-point steam delivery, dramatically reducing sterilization time while maintaining structural manageability
Solution Approach 2:
The patent employs dynamic elements including a rotatable steam nozzle that can rotate 360 degrees to cover all external surfaces of the bottle, and stretchable steam pipes that can extend and retract to reach inside the bottle. These dynamic components enable comprehensive steam coverage without requiring a complex fixed structure
2Reliability
If steam pipes are stretched into the feeding bottle cavity, then the sterilization completeness is improved, but the risk of steam pipe contact with inner bottle wall increases
Solution Approach 1:
The patent uses flexible steam pipes that can stretch and conform to the bottle's interior space. These flexible pipes can reach deep into the bottle cavity to deliver steam for complete internal sterilization, while their flexibility allows them to navigate around the bottle contents without rigid contact that could cause harm or incomplete sterilization
3Reliability
If auxiliary steam jet bar is used to sterilize nipple and inner wall, then the sterilization coverage is improved, but the bottle and nipple become unstable and sterilization completeness deteriorates
Solution Approach 1:
The patent separates the sterilization functions into distinct components: the rotatable steam nozzle handles external bottle sterilization, stretchable steam pipes handle internal cavity sterilization, and the upper basket with air jet holes handles nipple sterilization. This extraction of functions allows each component to optimize its sterilization approach without interfering with bottle stability
4Device complexity
If main steam jet bar with fixed nozzle is used, then the steam delivery is simplified, but the steam distribution uniformity deteriorates
Solution Approach 1:
The patent replaces the fixed nozzle with a rotatable steam nozzle that can rotate 360 degrees around the bottle. This dynamic rotation ensures uniform steam distribution across all external surfaces of the bottle, achieving comprehensive sterilization coverage without requiring multiple fixed nozzles or complex positioning mechanisms
