Insect Screen Frame Corner Connectors for Easy Secure Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect and pollen protection screen frame systems are complex to assemble, require multiple steps, and lack a simple and secure method for connecting profile strips and attaching mesh fabric, leading to inefficiencies in adaptation to different opening sizes and boundary conditions.
Innovation Solution
A frame system utilizing two-part corner connectors with joining legs that can be easily assembled and securely connected, allowing for flexible adaptation to various opening sizes, with the option of pre-assembling components and using telescopic profiles to simplify installation and reduce material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional corner connectors with multiple separate components are used, then the connection is secure and reliable, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple separate components of the corner connector into a single integrated component. The corner connector includes a first leg section and a second leg section that are already connected to each other, forming one piece that can be inserted into the profile strips simultaneously, eliminating the need for separate assembly steps and reducing the number of parts to handle.
Solution Approach 2:
The corner connector is segmented into functional sections (first leg section and second leg section) that are pre-connected, allowing each section to interface with different profile strips while maintaining structural integrity as a single component.
2Ease of operation
If the frame system is designed to be easily assembled and disassembled, then the installation and maintenance become simpler, but the connection stability and strength may be compromised
Solution Approach 1:
The corner connector incorporates a releasable connection mechanism that allows the connector to be easily detached from the profile strips when needed, while maintaining strong mechanical engagement during normal use. The connection can be released by actuating a release element that disengages the locking mechanism.
Solution Approach 2:
The corner connector includes pre-formed receiving channels and locking features that are prepared in advance, allowing the profile strips to be simply inserted and automatically locked into position without requiring complex assembly steps or additional fastening operations.
3Quantity of substance
If traditional packaging methods are used for the assembly kit, then all components can be included, but the packaging volume and material usage increase
Solution Approach 1:
By combining multiple corner connector components into a single integrated piece, the overall volume of components requiring packaging is reduced. The first and second leg sections are connected within the same component, eliminating the need for separate packaging spaces for each section.
Solution Approach 2:
The corner connector is designed with a compact structure where the first and second leg sections are nested or folded together in a space-efficient manner, allowing the entire connector to occupy minimal packaging volume while still providing all necessary functional features.
