Steam Distribution Channel Layout for Faster Ironing Plate Steam Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing irons suffer from bulky steam distribution chambers that cause a decrease in steam flow speed due to larger passage sections, leading to inefficient steam emission through outlet holes.
Innovation Solution
A compact steam distribution chamber with a winding channel shape around a projecting wall, where steam outlet holes are arranged in a row to maintain high steam flow speed, and a T-shaped wall for optimal compactness and heat transfer, along with passage restrictions and bends to enhance evaporation and steam penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the distribution chamber has a larger passage section to accommodate steam flow, then the chamber volume increases, but the steam flow speed decreases
Solution Approach 1:
The patent transforms the traditional three-dimensional chamber into a two-dimensional channel structure that winds around a projecting wall. This dimensional change allows the distribution path to be extended in length while maintaining a compact cross-sectional area, thereby preserving steam flow speed while achieving compact overall dimensions.
Solution Approach 2:
The distribution channel employs a winding, curved path around the projecting wall rather than a straight linear configuration. This curvature allows the channel to maximize its length within a compact space, extending the steam distribution path without increasing the overall footprint or compromising flow velocity.
2Reliability
If the distribution chamber passage section is increased to improve steam distribution, then the chamber becomes bulkier, but the device complexity increases
Solution Approach 1:
The distribution system is segmented into a winding channel structure that follows the contour of the projecting wall, with steam outlet holes distributed along the channel path. This segmentation allows effective steam distribution across multiple zones while maintaining a simple, integrated channel structure rather than a complex multi-chamber system.
Solution Approach 2:
The distribution channel is nested around the projecting wall, utilizing the wall's structure as a central core. This nesting arrangement allows the distribution pathway to be embedded within the existing structural framework, reducing overall device complexity while maintaining effective steam distribution.
3Quantity of substance
If the distribution channel length is increased to supply multiple steam outlet holes, then the channel width must be reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The channel width is optimized locally at different positions along its length. The width varies between one and three times the diameter of the steam outlet holes depending on the local requirements for steam flow distribution and outlet hole size, allowing flexible adaptation to different outlet configurations without compromising manufacturing feasibility.
