Solution Overview
Problem
Current feeding-bottle sterilizers face issues with incomplete sterilization due to short sterilization times and unstable positioning, leading to ineffective distribution of high-temperature steam.
Innovation Solution
A feeding-bottle sterilizer design featuring a base, upper cap, and steam supply device with multiple steam nozzles and baffles for even steam distribution, including a 360° rotatable steam nozzle and a baffle to prevent steam overflow, ensuring thorough and rapid sterilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple container structure with heating device is used, then device complexity is reduced, but sterilization completeness deteriorates due to longer steam filling time
Solution Approach 1:
The sterilization chamber is divided into multiple zones with dedicated steam nozzles: a first steam nozzle for the upper portion, a second steam nozzle for the lower portion, and a third steam nozzle for the basket area. This segmentation allows simultaneous sterilization of different regions, completing steam distribution quickly while maintaining simple overall structure.
Solution Approach 2:
The steam delivery system transitions from single-point or single-direction spraying to multi-dimensional steam distribution. The first and second nozzles spray in different directions (upward and downward respectively), while the third nozzle provides lateral steam supply, creating comprehensive three-dimensional coverage that ensures complete sterilization rapidly.
2Productivity
If steam is sprayed via fixed nozzle to sterilize feeding bottle, then sterilization speed is improved, but sterilization completeness deteriorates due to unstable bottle positioning
Solution Approach 1:
The first steam nozzle is designed with rotatability, allowing the nozzle to rotate and adjust its spraying direction dynamically. This dynamic adjustment ensures that steam is distributed evenly across different positions of the feeding bottle regardless of its exact placement, maintaining both rapid sterilization speed and complete coverage.
Solution Approach 2:
Different regions of the sterilization chamber receive steam with locally optimized characteristics. The first nozzle provides targeted steam to the upper portion where the bottle body resides, the second nozzle delivers steam to the lower portion, and the third nozzle supplies steam to the basket area. This local quality optimization ensures each region receives appropriate steam intensity for complete sterilization.
3Productivity
If steam is sprayed directly into feeding bottle to sterilize inner wall, then sterilization speed is improved, but sterilization completeness deteriorates due to nozzle contact with bottle wall
Solution Approach 1:
The second steam nozzle is designed with a curved spray trajectory that arches over the bottle opening rather than spraying directly along the central axis. This curved path allows the nozzle to extend into the bottle cavity without the nozzle body contacting the inner wall, enabling direct inner wall sterilization while avoiding contact interference that would compromise sterilization completeness.
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 design ensures rapid and thorough sterilization by evenly distributing high-temperature steam throughout the sterilization space, reducing sterilization time and preventing steam leakage, while allowing for easy cleaning and positioning of bottles and nipples.
Implementation Method 1
heats and evaporates water into water vapor by a heating device
Implementation Method 2
the steam is sprayed into the sterilization chamber via the main steam jet bar to sterilize the nipple and outer wall of the feeding bottle
Implementation Method 3
a pump arranged on the lower bottom surface of the base, a heating body for heating the water body
