Spring-Loaded Screen Frame Wedge Mechanism for Safe Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window screen systems that require installation from outside the building are cumbersome and pose safety hazards due to pivoting metal clips that can fall out or cause injuries, and existing systems for inside installation are inefficient and prone to clip loss.
Innovation Solution
A screen frame grasping and removal system featuring pull tabs with locks and a spring-loaded wedge mechanism that allows for easy installation and removal from inside the building, using pull tabs with locks and outwardly springing bias to stabilize the screen frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pivoting metal clips are used for screen installation, then the screen can be installed from inside the building, but the clips can fall out of guide slots, be lost, and are cumbersome to operate
Solution Approach 1:
The harmful pivoting metal clips are completely extracted and removed from the system. Instead, the patent uses a spring-loaded wedge mechanism that engages with the window frame through the screen mesh itself, eliminating the need for separate clips that can fall out or be lost.
Solution Approach 2:
The screen mesh itself serves as an intermediary element. The spring-loaded wedge mechanism pushes against the screen mesh, which in turn transfers the force to engage with the window frame, eliminating the need for separate metal clips while maintaining the connection function.
2Ease of operation
If pivoting metal clips are used for screen installation, then the screen can be installed from inside the building, but the clips have pointy ends, posing a safety hazard
Solution Approach 1:
The harmful pointy metal clips are completely extracted from the system. The patent replaces them with a spring-loaded wedge mechanism that makes contact through the screen mesh, eliminating exposed sharp points that could cause injury.
Solution Approach 2:
The system uses the existing screen mesh as a disposable or replaceable element that absorbs the mechanical interaction. The wedge mechanism interacts with the mesh rather than requiring separate durable metal clips, simplifying the overall system and removing safety hazards.
3Reliability
If existing screen systems require installation from outside the building, then the screen can be securely installed, but the process is cumbersome and inconvenient
Solution Approach 1:
The patent inverts the traditional installation approach. Instead of requiring installation from outside the building, the spring-loaded wedge mechanism enables secure installation from inside the building by pushing the screen into engagement with the window frame through the mesh, reversing the conventional workflow.
Solution Approach 2:
The spring-loaded wedge mechanism is self-actuating. When installed from inside, the spring automatically engages the wedge with the window frame through the screen mesh, providing secure installation without requiring external assistance or complex manual manipulation.

AI summary
In one embodiment the present invention is a screen frame grasping and removal system comprising at least one pull tab. There is at least one lock to lock each tab. The frame defines openings to receive the tab and lock cooperation, the tab and lock openings communicating with each other to permit the lock to engage the tab. In another embodiment the above includes one side of the frame defining an opening to receive the tab and an opening to receive the lock, the tab and lock openings communicating with each other to permit the lock to engage the tab; and a second side of the frame contains therein at least one outwardly springing bias. The screen first and second side opposing each other.
