Portable pressing appliance comprising a removable accessory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable pressing appliances with removable accessories for cleaning or sheen removal reduce heat transfer efficiency due to the accessory covering the hot surface, and require orientation-specific use for effective fiber lifting.
Innovation Solution
A portable pressing appliance with a steam emission head featuring a protrusion and peripheral surface for accessory attachment, allowing the accessory's treatment surface to maintain contact with the garment while providing improved ergonomics and thermal stability through magnetic retention and reversible design with different treatment surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the accessory covers the hot surface of the treatment face, then the accessory provides cleaning and sheen removal functions, but the heat transfer to the garment is reduced and pressing efficiency decreases
Solution Approach 1:
The treatment face is segmented into two distinct functional zones: a hot surface for pressing and a cleaning surface with protrusions for fiber lifting. This segmentation allows each surface to perform its specific function optimally without interfering with the other, resolving the contradiction between cleaning capability and heat transfer efficiency.
2Adaptability or versatility
If the pad for lifting threads or fibers is arranged on only one side of the steam outlet orifices, then the accessory provides fiber lifting function, but the user must pay attention to orientation to properly treat the garment
Solution Approach 1:
The accessory employs asymmetric design with different surfaces (hot surface, cleaning surface, steam outlet orifices) arranged in a specific non-symmetric pattern. This asymmetric arrangement creates distinct functional faces that guide the user on proper orientation through their unique characteristics, making ease of operation achievable through intuitive design rather than requiring conscious orientation awareness.
3Adaptability or versatility
If the accessory is removably mounted on the treatment face, then the accessory can be attached and detached for different uses, but the accessory may affect the stability and thermal contact with the garment
Solution Approach 1:
The patent replaces traditional mechanical attachment systems (screws, clips, adhesives) with magnetic attachment. The magnetic field provides reliable, stable, and consistent holding force that ensures reliable thermal contact between the accessory and treatment face while allowing easy removal. This substitution of mechanical system with magnetic field resolves the contradiction between removable mounting and thermal contact stability.
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 cleaning performance and ergonomics by ensuring consistent heat transfer and versatile treatment options with interchangeable accessories that maintain contact with the garment, regardless of orientation, and extend the accessory's longevity.
Implementation Method 1
the attachment device comprises magnetic means ensuring the retention of the accessory on the treatment face
Implementation Method 2
the hot surface is arranged at the end of a protrusion that projects on the body, at the treatment face
Implementation Method 3
the treatment face comprising at least one steam outlet orifice and one hot surface
