Profile Connector with Swivel Joint for Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing profile connectors for building opening frames, such as insect protection devices, require complex assembly efforts and large packaging due to the need for precise alignment and assembly of multiple components, which increases user effort and packaging size.
Innovation Solution
A profile connector with a rotary joint allowing the connecting legs to pivot from a compact position to a 90-degree assembly position, secured by a fixing element inserted into receiving channels, simplifying assembly and reducing effort by allowing pre-assembly in a compact form that can be easily unfolded and adapted to different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If profile connectors are preassembled in pairs at right angles, then assembly effort is reduced, but packaging size increases due to large area occupation
Solution Approach 1:
The connecting legs are designed to be nested within each other in the initial position, with one connecting leg inserted into the other, allowing compact packaging while maintaining the preassembled configuration that reduces assembly effort
Solution Approach 2:
The connecting legs are designed with relative movability through a rotary joint, allowing them to transition from a compact initial position to an extended assembly position at right angles, enabling both compact packaging and easy assembly
2Stability of the object's composition
If multiple components require precise alignment and assembly, then connection stability is improved, but assembly complexity increases
Solution Approach 1:
The receiving channels are pre-positioned and aligned in the initial position, allowing the fixing element to be inserted before the connecting legs are pivoted to the final position, simplifying the assembly process while ensuring stable connection
Solution Approach 2:
The fixing element acts as an intermediary that secures the relative position of the connecting legs during assembly, enabling precise alignment to be achieved through a simple insertion action rather than complex adjustment procedures
