Expandable Two-Plate Window Screen for AC Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window-mounted air conditioners face challenges with non-standard window sizes, as existing accordion-like side panels can damage window frames, are not always fully sized, and are unsightly and difficult to store.
Innovation Solution
A two-plate window screen that expands to fit any window size without connectors, featuring slidably arranged solid plates for easy installation and storage, with U-shaped brackets for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If accordion-like side panels are used to fill open window space, then the window space can be filled, but the window frame may be damaged by connectors (screws or tape)
Solution Approach 1:
The invention removes the harmful connectors (screws or tape) from the system by using a foam material that can be directly adhered to the window frame and air conditioner casing, eliminating the need for mechanical fasteners that could damage the window frame
Solution Approach 2:
The invention changes the physical state of the filling material from a rigid panel requiring mechanical fasteners to a flexible foam material that can be molded and adhered, transforming the installation method from mechanical connection to chemical adhesion
2Area of stationary object
If accordion-like side panels are used to fill open window space, then the window space can be filled, but the panels are physically unsightly and difficult to store
Solution Approach 1:
The invention changes the material properties from rigid accordion panels to flexible foam that can be molded into smooth, aesthetically pleasing shapes and can be easily folded or rolled for compact storage
3Area of stationary object
If accordion-like side panels are used, then some window space can be filled, but they may not be appropriately sized to fill the space completely
Solution Approach 1:
The invention uses foam material with adjustable expansion properties that can be molded to any required size and shape, allowing complete adaptation to different window openings and air conditioner configurations
Solution Approach 2:
The foam material provides dynamic adaptability through its moldable nature, allowing it to be shaped and sized to perfectly fit any window opening regardless of dimensions or configuration
