Adjustable Window Frame Assembly for Varying Door Thicknesses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window assemblies for garage doors face challenges in accommodating varying door thicknesses and providing effective sealing and impact resistance, limiting their versatility and durability.
Innovation Solution
A window assembly design featuring adjustable interior and exterior frame elements, where the interior frame element's inner engagement portion varies in length based on door thickness, while the exterior frame element's inner engagement portion remains constant, ensuring a secure fit and enhanced sealing, with optional impact elements for added durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length inner engagement portion is used in existing window assemblies, then the manufacturing process is simple, but the assembly cannot accommodate varying door thicknesses
Solution Approach 1:
The frame is divided into interior and exterior frame elements that can be separately manufactured and then assembled together. The interior frame element contains the adjustable inner engagement portion, while the exterior frame element provides the outer engagement portion. This segmentation allows the interior frame element to be customized for different door thicknesses without redesigning the entire frame structure.
Solution Approach 2:
The inner engagement portion length is made variable rather than fixed. The interior frame element can be manufactured with different inner engagement portion lengths to match specific door thicknesses, making the window assembly adaptable to varying door dimensions while maintaining a relatively simple overall structure.
2Reliability
If existing window assemblies use standard frame designs, then manufacturing is straightforward, but sealing effectiveness against external elements is insufficient
Solution Approach 1:
The sealing system is segmented into multiple components: the interior frame element with its inner engagement portion, the exterior frame element with its outer engagement portion, and sealing elements positioned between them. This segmentation allows each component to contribute to the overall sealing effectiveness, creating multiple barriers against external elements while maintaining manufacturability.
Solution Approach 2:
The frame elements are designed with pre-formed engagement portions and sealing surfaces that are prepared in advance during manufacturing. The interior and exterior frame elements are configured to work together as a pre-assembled unit that can be installed on the door, reducing on-site assembly complexity while ensuring proper sealing alignment.
3Strength
If existing window assemblies lack additional protective features, then the structure remains simple, but impact resistance is limited
Solution Approach 1:
The frame elements are constructed using composite materials that combine the strength of molded plastic with the durability of integrated metal reinforcement or impact-resistant additives. This composite construction enhances impact resistance while maintaining a relatively simple single-piece molded structure for each frame element, avoiding the need for complex multi-component assemblies.

AI summary
A window assembly includes a frame and a window glazing. The frame has an interior frame element and an exterior frame element. The interior frame element has a first internal surface, a first outer engagement portion extending from the internal surface, and a first inner engagement portion extending from the first internal surface. The exterior frame element has a second internal surface, a second outer engagement portion extending from the second internal surface, and a second inner engagement portion extending from the second internal surface. The interior and exterior frame elements are configured to be connected to each other with the window glazing disposed therebetween. A first length of the first inner engagement portion is greater than or equal to a second length of the second inner engagement portion.
