Segmented Inflatable Air Cushion Tool for Frame Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auxiliary tools for positioning window and door frames in wall openings provide limited force and stability, with a single point of load that can lead to incorrect support and leveling, especially when dealing with non-homogeneous elements or those requiring extra force for alignment.
Innovation Solution
The auxiliary tool employs multiple inflatable air cushion members connected by a connecting element to form a stable support with multiple load points, allowing for stepless force adjustment and distribution across a larger area, ensuring precise positioning and alignment of elements without leaving pressure marks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single air cushion member is used, then the device complexity is reduced, but the positioning precision and stability deteriorate due to single point of load
Solution Approach 1:
The auxiliary tool is divided into multiple air cushion members (at least two) that can be selectively inflated independently. Each air cushion member acts as a separate positioning point, allowing precise adjustment of the frame element at multiple locations simultaneously, thereby improving positioning precision while maintaining manageable device complexity through modular design
2Manufacturing precision
If multiple air cushion members are used, then the positioning precision and stability improve, but the device complexity increases
Solution Approach 1:
Each air cushion member is designed with universal functionality to perform multiple tasks: positioning, leveling, and supporting the frame element. The connecting element provides a common inflation system that can be controlled from a single location, allowing the multiple air cushion members to function as an integrated system rather than separate complex components, thereby improving positioning precision without proportionally increasing device complexity
3Device complexity
If a single point of load is used, then the device simplicity is maintained, but the reliability deteriorates as there is only one point of attack for straightening and displacing
Solution Approach 1:
The load application is segmented into multiple independent air cushion members that can be inflated selectively. This creates multiple points of attack for straightening and displacing the frame element, ensuring that if one air cushion member malfunctions or is insufficient, others can compensate, thereby improving reliability while maintaining device simplicity through the modular nature of the segmented design
4Ease of operation
If flat bag units are used, then the ease of operation improves for controlled displacing, but the force exertion capability deteriorates compared to other cushion shapes
Solution Approach 1:
The flat bag units are connected through a common inflation system using pneumatic principles. By controlling the air pressure through the connecting element, substantial force can be exerted by each flat bag unit while maintaining the ease of operation for controlled displacing. The pneumatic system allows force multiplication where a small activating force on the inflation mechanism produces large forces at the contact points with the frame element
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
This solution enables the precise and stable positioning of elements with adjustable force distribution, even for non-homogeneous or heavy elements, enhancing safety by preventing pressure marks and ensuring the tool remains effective even if one air cushion member malfunctions.
Implementation Method 1
the air cushion members being present at this mentioned one side of the wall opening thus become inflated more or less in respect to the pressure which simultaneously is being excerted through the other oppositely arranged flat bag units
Implementation Method 2
the flat bag units will not be able to carry the individual frames by means of the frictional pressure which is exerted against the side surfaces of the vertical oriented gaps being present between the individual frames and the receiving opening in the wall

AI summary
An auxiliary tool to be employed when positioning elements, such as window and door frames is described, in relation to an adjacent flat or plane, such as within wall openings, whereby the auxiliary tool comprises an inflatable air cushion member (6) which through a hose connection means (10) is connected to a pumping device (12) and a bleeding valve (16). The air cushion member is shaped as a flat bag unit. The auxiliary tool furthermore comprises connecting elements (42, 46, 48) for the mutual fixation of an air cushion member (6) comprising one or more adjacent air cushion members which have two or more mutually fixed air cushion members (6) which selectively are inflatable. These are in a side by side relationship provided positioned in a common plane so that in total the flat bag unit sides form opposing sides within the auxiliary tool.
