Caravan Window Adapter Frame With Gap-Locking Fixing Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing framed windows in caravanning vehicles are not reliably mounted and sealed, particularly under varying thermal conditions, and lack a visually appealing integration with the vehicle interior.
Innovation Solution
An adapter frame system with fixing elements that fit securely into the gap between the vehicle wall cutout and the frame window, using force-fit and form-fit mechanisms, allowing for tool-free assembly and adjustment, and incorporating a blackout system for aesthetic and functional enhancement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If Velcro or adhesive tape is used to fix the adapter frame, then the mounting process is simple, but the mounting reliability deteriorates under thermal influences
Solution Approach 1:
The patent replaces the adhesive/Velcro fixing system with a mechanical fixing system using fixing elements that have a insertion portion inserted into the gap between the frame window and vehicle wall cutout, and a fixing portion that engages with the frame profile section. This mechanical engagement provides reliable mounting that is independent of temperature influences while maintaining ease of assembly through the snap-fit mechanism.
2Stability of the object's composition
If the adapter frame is rigidly fixed to prevent movement, then mounting stability is improved, but adjustment capability deteriorates
Solution Approach 1:
The patent implements a dynamic fixing system where the fixing elements allow the adapter frame to be adjusted in position during installation by sliding along the frame profile section, and then locked in place through the engagement of the fixing portion with the frame profile. This provides both adjustment capability during mounting and stability during operation.
3Device complexity
If traditional sealing methods are used, then manufacturing simplicity is maintained, but sealing reliability under thermal expansion deteriorates
Solution Approach 1:
The patent addresses thermal expansion effects by designing the fixing elements and frame profile sections with appropriate clearance and engagement geometry that accommodates dimensional changes due to temperature variations. The gap between the frame window and vehicle wall cutout, combined with the mechanical engagement of the fixing elements, allows for thermal movement while maintaining reliable sealing.
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
Ensures reliable mounting and sealing of framed windows, providing thermal insulation and a visually appealing integration with the vehicle interior, while allowing for easy adjustment and integration of blackout systems.
Implementation Method 1
the fixing element comprises a window mounting section with a plug-in web and at least two elastically movable barbs projecting from at least one side of the plug-in web
Implementation Method 2
it can be inserted into a gap between the vehicle wall cutout and the frame window in a force-fit and/or form-fit manner
