Insect Protection Frame Corner Connector Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect and pollen screen frame systems face challenges in achieving a balance between ease of assembly, stability, and a flat design, while ensuring secure mounting on building openings like windows.
Innovation Solution
The corner connector features an angle element with sliding blocks and internal threads, allowing for detachable mounting with a retaining clip, and a profile contour that accommodates a slot nut for secure screwing, resulting in a flat and stable frame system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional corner connectors are used to connect longitudinal and transverse profiles, then the frame system can be assembled and mounted, but the design becomes bulky and less flat
Solution Approach 1:
The corner connector integrates multiple functional elements into a nested structure where the angle element with joining legs connects to profiles, while sliding blocks with internal threads and retaining clips are nested within the profile contours. This nesting arrangement eliminates the need for separate mounting brackets and reduces the overall bulk of the corner connection system.
Solution Approach 2:
The invention merges the corner connection function and the mounting function into a single integrated corner connector design. The angle element combines joining legs for profile connection with integrated sliding blocks that provide both positioning and mounting capabilities, eliminating the need for separate mounting hardware and achieving a flatter overall design.
2Ease of operation
If the frame system is designed to be detachable for easy assembly and disassembly, then ease of operation is improved, but mounting stability may be compromised
Solution Approach 1:
The corner connector employs dynamic elements including sliding blocks that can move within profile contours for easy positioning, and spring legs on retaining clips that provide automatic engagement and secure locking. The spring mechanism maintains constant contact force for stable mounting while allowing simple release for disassembly, achieving both ease of operation and mounting reliability.
Solution Approach 2:
The sliding block acts as an intermediary element between the corner connector and the profile. It provides a smooth transition for assembly by allowing the corner connector to slide into position, then secures the connection through the internal thread and retaining clip, ensuring stable mounting while maintaining ease of operation.
3Reliability
If multiple through-openings are added to joining legs for reliable mounting, then mounting reliability is improved, but the corner connector becomes more complex
Solution Approach 1:
The sliding block with internal thread serves multiple functions: it provides threaded engagement for secure mounting, acts as a locating element within the profile contour, and integrates with the retaining clip mechanism. This multi-functional design eliminates the need for separate through-openings in the joining legs, achieving mounting reliability without increasing overall structural complexity.
