Press-fit Window Insert With Flexible Fin Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storm window systems are difficult to install and remove, often requiring precise measurements and mechanical attachment, which can be time-consuming and labor-intensive, especially for window frames that are out of square or have irregular shapes.
Innovation Solution
A press-fit window insert system that allows for less precise measurements (up to ¼ inch deviation) and uses a flexible fin and corner flap design to provide a secure fit and seal, eliminating the need for precise diagonal measurements and mechanical attachment, with components like a carrier, fin, fastening clip, and corner snap for easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mechanical attachment with mounting hardware is used, then the storm window can be securely attached to the window frame, but the installation and removal process becomes difficult and time-consuming
Solution Approach 1:
The patent replaces mechanical attachment systems (screws, clips, fasteners) with a press-fit insertion system. The storm window panel is designed to be directly inserted into the window frame opening, where friction and geometric interlocking provide secure attachment without requiring additional mounting hardware. This substitution eliminates the need for tools and complex assembly steps while maintaining attachment security.
Solution Approach 2:
The storm window system is divided into separate modular components: the panel, the frame, and corner pieces. These segments can be independently manufactured and assembled through simple insertion, allowing for easy installation and removal. The segmentation enables the system to be disassembled and reassembled multiple times without damage, addressing both security and ease of operation requirements.
2Manufacturing precision
If precise measurements and diagonal measurements are required, then the storm window can fit accurately in square window frames, but the installation process becomes time-consuming and may require professional assistance
Solution Approach 1:
The patent changes the critical parameter from precise diagonal measurements to simple width and height measurements. The press-fit design incorporates adjustment tolerances that accommodate variations in measurement accuracy, allowing installation without professional-grade measuring equipment. This parameter change reduces installation time while maintaining adequate fit accuracy for most window frames.
Solution Approach 2:
The storm window frame includes flexible or adjustable components that can accommodate out-of-square conditions and irregular shapes. The corner pieces and frame sections can be adjusted during installation to compensate for measurement variations, providing a secure fit without requiring perfectly precise measurements. This dynamic adjustment capability reduces both measurement precision requirements and installation time.
3Strength
If the storm window is made heavy for durability, then it provides better protection, but it becomes difficult to manipulate and install
Solution Approach 1:
The patent employs thin-film materials such as plastic or vinyl for the storm window panel, which provide adequate protection while remaining lightweight and easy to manipulate. These thin films can be stretched and secured to the frame, providing durability without the weight of traditional glass or heavy materials. The flexibility of thin films allows for easy handling during installation and removal by single individuals.

AI summary
A press-fit window insert configured to provide secondary protection to an existing window, having a carrier, a fin, and a fastening clip. The carrier includes a substantially rigid framework having channels within the framework configured to securely accept one or more attachments. The fin extends from the carrier and includes a substantially flexible blade extending from a base portion of the fin. The base portion of the fin is configured to interlock the fin to the carrier. The fastening clip includes a substantially rigid brim extending from a base portion of the fastening clip. The base portion of the fastening clip is configured to interlock the fastening clip to the carrier.
