Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clothes care devices face inefficiencies in steam transfer and distribution, leading to suboptimal deodorizing, wrinkle removal, and static reduction due to inadequate steam spray nozzle designs that fail to mitigate pressure and rotation forces effectively.
Innovation Solution
The proposed clothes care device incorporates a steam spray nozzle with a guide member that includes a first guide with multiple poles and a second guide with a ribbed structure to mitigate steam pressure and rotation forces, along with a steam spray opening that adjusts its dimensions based on the internal volume of the clothes care chamber to maintain efficient steam transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional steam spray nozzle is used, then the structure is simple, but the steam transfer efficiency is insufficient due to inadequate pressure and rotation force mitigation
Solution Approach 1:
The guide member is divided into multiple poles arranged in an array, with each pole independently mitigating steam pressure. This segmentation allows the complex function of pressure mitigation to be achieved through multiple simple, identical elements, improving steam transfer efficiency while keeping individual components simple and manufacturable.
Solution Approach 2:
The guide member acts as an intermediary element between the steam generator and the clothes care chamber. It mediates the steam flow by mitigating pressure and rotation forces, ensuring efficient steam transfer without requiring complex control systems or additional active components.
2Quantity of substance
If the steam spray opening area is increased to improve steam application, then more steam reaches the clothes, but the spray direction becomes inconsistent and pressure control deteriorates
Solution Approach 1:
Different regions of the steam spray system have different functions: the guide member poles are positioned to specifically mitigate pressure in the steam flow path, while the steam spray opening is designed with specific dimensions to control spray direction. This local optimization allows increased steam application while maintaining consistent spray direction through carefully positioned structural elements.
Solution Approach 2:
The dimensions of the steam spray opening (horizontal length l1 and vertical length h1) are specifically adjusted based on the internal volume of the clothes care chamber. This parameter optimization ensures that adequate steam quantity is delivered while maintaining proper spray direction consistency for effective clothes care.
3Productivity
If the steam spray opening dimensions are fixed, then manufacturing is simple, but the steam transfer efficiency varies with different clothes care chamber volumes
Solution Approach 1:
The steam spray opening dimensions (horizontal length l1 and vertical length h1) are designed to change according to the internal volume of the clothes care chamber, while maintaining a preset ratio relationship. This allows optimization of steam transfer efficiency for different chamber sizes while using simple proportional scaling that maintains manufacturing ease through standardized design relationships.
