Reinforced Flex Window Screen Frame for Lateral Force Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window screen systems are lightweight and offer little resistance to force, posing a risk of falling accidents, especially in homes with children or multi-story dwellings, as they are not designed to withstand lateral forces effectively.
Innovation Solution
A sturdy and easily removable window screen system with a reinforced flex screen design, featuring a window frame with interlocking winding rods and corner caps, secured by a polymer seal, which can withstand lateral forces from large objects or humans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lightweight screen system is used, then ease of installation and removal is improved, but resistance to lateral force deteriorates
Solution Approach 1:
The screen system is divided into modular components: a screen frame with winding rods, corner caps, and a polymer seal that can be independently assembled and disassembled. This segmentation allows easy installation/removal while maintaining structural integrity through the reinforced corner connections.
Solution Approach 2:
The system combines multiple materials with complementary properties: aluminum or steel winding rods for flexibility and strength, rigid corner caps for structural reinforcement, and polymer seals for weatherproofing. This composite approach achieves both ease of operation and high strength resistance to lateral forces.
2Strength
If a reinforced screen system is used, then resistance to lateral force is improved, but device complexity increases
Solution Approach 1:
Multiple functions are merged into integrated components: the corner caps simultaneously provide structural reinforcement, secure the winding rods in place, and seal the corners with polymer material. The winding rods serve both as flexible screen support and as structural elements that can be easily engaged with the corner caps, reducing overall system complexity while maintaining high strength.
3Ease of operation
If easy removal design is used, then ease of operation is improved, but reliability deteriorates
Solution Approach 1:
The system transitions between two dynamic states: during installation/removal, the winding rods can be easily disengaged from the corner caps for convenient operation; during normal use, the same components lock together to form a rigid, reliable structure that can withstand lateral forces and prevent falling accidents. This dynamic design allows the system to adapt its properties based on operational needs.

AI summary
A window screen system including two main parts, namely, a reinforced window frame and a combined window and a force resistant flex screen system or assembly. The window frame has at least one forward and one reward vertical slot capable of receiving the combined window and flex screen. The frame is securable to a structure and extends thereinto providing for easy removal of the systems received in the vertical slots. The screen system is formed of a mesh flex screen material. Winding rods, with teeth extending therefrom, line each edge of the flex screen and engage the screen material rotatably secure the screen with the teeth. Each juncture of the winding rods is secured by a corner cap. The flex screen system is sealed with a polymer seal about the winding rods. A screen cap is securely placed along the top edge and secured by the polymer seal.
