Solution Overview
Problem
Existing garment steamers with inclinable ironing boards have complex mechanisms, fragile support structures, and instability during position changes, making operation cumbersome.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixing structure is configured to fix the inclinable structure to a desired position, then the position can be fixed, but the structure becomes complex
Solution Approach 1:
The locating mechanism uses the weight of the ironing board body itself to activate the locating portion, which then leans against the opposite edge of the quadrangle to prevent deformation and fix the position. The system serves itself by using its own components (the ironing board body's weight and the locating mechanism) rather than requiring external fixing structures.
Solution Approach 2:
The locating mechanism acts as an intermediary between the ironing board body and the support structure. The locating portion on one edge of the quadrangle leans against the opposite edge to prevent deformation, mediating the connection and enabling position fixation without complex fixing structures.
2Reliability
If a fixing structure is configured to fix the inclinable structure, then position can be fixed, but operation becomes complex
Solution Approach 1:
The ironing board body automatically activates the locating mechanism through its own weight during the tilting process. When the ironing board body is tilted, the locating portion automatically leans against the opposite edge of the quadrangle to prevent deformation and fix the position, eliminating the need for separate fixing operations.
3Device complexity
If the support structure is made fragile to allow inclination, then the structure can be simple, but support stability deteriorates
Solution Approach 1:
The support structure transitions from a static rigid structure to a dynamic quadrangle that can deform during position changes. The quadrangle deforms as the ironing board body tilts, allowing smooth transition between positions while maintaining simplicity. The locating mechanism then prevents further deformation to provide stability at the target position.
Solution Approach 2:
The locating mechanism serves as an intermediary that temporarily prevents quadrangle deformation. When the ironing board body is tilted to a desired position, the locating portion leans against the opposite edge of the quadrangle to prevent deformation, providing stability without requiring a rigid fixed structure.
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 solution simplifies the structure, enhances support stability, and enables easy position changes of the ironing board by leveraging a quadrangle's deformation to maintain stability without additional fixing operations.
Implementation Method 1
a quadrangle which deforms with a change of the position of the ironing board body
Implementation Method 2
at least one edge of the quadrangle is provided with a locating portion which, when the ironing board body is transformed between the first position and the second position, leans against an opposite edge of the quadrangle to prevent the quadrangle from deformation so as to locate the ironing board body
Implementation Method 3
at a first point, a back side of the ironing board body is rotatably connected to the support structure to allow the ironing board to be transformed between a first position and a second position

AI summary
The invention discloses a variable-position ironing board and a garment steamer, and belongs to garment ironing equipment. At a first point (A), a back side of an ironing board body (200) is rotatably connected to a support structure (100) to allow the ironing board body to be transformed between a first position and a second position; and a first link (310) and a second link (320) of a locating mechanism are located on the back side of the ironing board body (200) and rotatably connected to the support structure (100) and the ironing board body (200) to form a quadrangle (ABCD) which deforms with the change of the position of the ironing board body (200), and at least one edge of the quadrangle is provided with a locating portion which, when the ironing board body (200) is transformed between the first position and the second position, leans against an opposite edge of the quadrangle to prevent the quadrangle from deformation so as to locate the ironing board body (200) in the first position or the second position.
