Door Frame Corner Free Space for Universal Seal Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door and window frame arrangements are complex and costly to produce, requiring custom-dimensioned seam sealing parts that match specific frame geometries, limiting flexibility and efficiency in manufacturing.
Innovation Solution
The frame design includes a second inner surface that 'jumps back' from the base part, creating a free space for a fold sealing part, allowing identical sealing parts to be used across different geometries, with the option to fill the space fully or partially, and enabling adjustable mounting for effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the second inner surface extends to the bottom surface of the base part, then the frame geometry is compact, but the seam sealing part cannot be installed effectively
Solution Approach 1:
The patent creates a free space by making the second inner surface jump back from the bottom surface of the base part, utilizing the vertical dimension to provide installation space for the fold sealing part without expanding the horizontal footprint of the frame
2Adaptability or versatility
If custom-dimensioned seam sealing parts are used for specific frame geometries, then sealing effectiveness is optimized, but manufacturing complexity and costs increase
Solution Approach 1:
The patent designs the frame with a standardized free space configuration that can accommodate identical fold sealing parts across different frame geometries, making the sealing part universal and eliminating the need for custom-dimensioned seals for each frame variation
3Productivity
If the second inner surface jumps back to create free space, then identical fold sealing parts can be used for different frame geometries, but the frame structure becomes more complex
Solution Approach 1:
The patent segments the frame structure by creating a distinct free space region separated from the main frame body, allowing the fold sealing part to be installed independently in this segmented space, which simplifies manufacturing despite the structural modification
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 design simplifies production by allowing the use of universal fold sealing parts, reducing manufacturing complexity and costs, while ensuring effective sealing across various frame geometries and configurations.
Implementation Method 1
The fold sealing part is preferably made of an elastic material and/or it has fold sealing sections that are elastically deformable relative to one another. This enables the fold sealing part to be manufactured easily, for example by means of an injection molding process.
