Vacuum-Expandable Window Insert Mounting for Easy Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window inserts are difficult to install and remove, often requiring mechanical or magnetic attachments that are cumbersome and may not provide optimal thermal and acoustic insulation, especially when the panel size is smaller.
Innovation Solution
A shrink-expand fit system using a vacuum-sealable mounting system that allows the window insert to be easily installed by shrinking to fit within the window frame and then expanding to secure it in place without hardware, utilizing a vacuum sealer to adjust the fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a larger panel is used to maximize thermal and sound insulation, then insulation effectiveness is improved, but the elastic force required to hold it in place increases making removal difficult
Solution Approach 1:
The mounting system transitions from a static elastic bulb to a dynamic vacuum-sealable elastic portion that can be easily switched between expanded (secured) and shrunk (removed) states through vacuum application/release, allowing the same system to accommodate both large insulation panels and easy removal
Solution Approach 2:
The elastic portion's volume and sealing pressure are changed by applying or releasing vacuum through the valve, allowing the mounting force to be adjusted from high (when expanded under vacuum) to low (when shrunk), resolving the contradiction between strong holding force for large panels and ease of removal
2Ease of operation
If a smaller panel is used to ease removal, then ease of operation is improved, but thermal and sound insulation effectiveness is reduced
Solution Approach 1:
The system allows small panels to achieve effective insulation by using the vacuum-sealed expanded state to ensure tight fitting, while removal remains easy by simply releasing the vacuum to shrink the elastic portion
Solution Approach 2:
The traditional mechanical elastic force is replaced with a vacuum-based holding mechanism, allowing the same small panel to generate sufficient holding force through vacuum pressure differential without requiring large size
3Reliability
If traditional mechanical or magnetic mounting hardware is used, then secure attachment is achieved, but installation complexity and difficulty increase
Solution Approach 1:
The mounting function is merged into the window insert panel itself through the elastic portion that surrounds the panel perimeter, eliminating separate mounting hardware and simplifying the overall system while maintaining secure attachment
Solution Approach 2:
The elastic portion with vacuum valve performs self-mounting by being stretched and sealed around the window frame opening, creating its own secure attachment without requiring external mechanical or magnetic hardware

AI summary
A shrink-expand fit system for mounting a panel within an existing window frame. The system includes an elongated shrinkable-expandable elastic portion and an elongated groove portion. The groove portion is configurated to securely receive and hold the panel. The shrinkable portion can be sealed to create an airtight space. The shrinkable portion includes a vacuum seal valve and can shrink under vacuum and expand under atmospheric pressure to tightly hold the panel against the window frame.
