Awning Arm Wire Protector Clip Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing articulated arm structures for awnings with integrated LED lighting face challenges in ease of assembly, aesthetic appearance, and effective lighting area coverage due to visible wire protectors and complex configurations that obstruct wire passage and create dark spots.
Innovation Solution
The articulated arm structure features clip-fixed wire protector parts that integrate flush with elbows, eliminating the need for screws and protrusions, allowing smoother assembly and increased space for connectors, enabling full LED strip illumination by housing connectors between wire protectors and elbows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire protectors are fixed to elbows by means of screws, then the wire protector parts can be securely attached, but the assembly becomes more complex and requires tools for installation and removal
Solution Approach 1:
The patent replaces the screw-based mechanical fastening system with a clip-based system. The clip part has a C-shaped configuration that embraces the wire protector and clips into recesses on the elbow, eliminating the need for screws and threaded holes. This substitution maintains secure attachment while dramatically simplifying the assembly process to require no tools.
Solution Approach 2:
The patent extracts the fastening function from the wire protector part itself and places it in a separate clip part. This separation allows the wire protector to have a simpler, smoother configuration without protrusions, while the clip part handles the attachment function by embracing the wire protector and clipping into the elbow recesses.
2Reliability
If wire protectors have crown-shaped protrusions for fitting into joints, then they can be secured to elbows, but they complicate the shape and may collide with wires during insertion
Solution Approach 1:
The patent removes the fitting function from the wire protector part by eliminating crown-shaped protrusions. Instead, the wire protector has a smooth inner face that fits cleanly into the elbow. The fitting and securing function is extracted and placed in the clip part, which embraces the wire protector and clips into recesses on the elbow, ensuring secure attachment without complex wire protector geometry.
Solution Approach 2:
Instead of the wire protector having protrusions that fit into the elbow, the patent inverts the approach: the wire protector has a smooth fitting surface, and the elbow has recesses that receive the wire protector. The clip part then secures the assembly by clipping into these recesses, reversing the traditional protrusion-fit approach.
3Reliability
If connectors joining LED strips are placed in profile housings, then they can be secured, but they occupy space that prevents full illumination of LED strips
Solution Approach 1:
The patent moves the connectors from the internal profile housing space (2D plane) to the external joint area between the wire protector and elbow (3D space). This dimensional relocation places connectors in the notch area where they do not obstruct the LED strip housing, allowing the LED strip to extend fully to the profile end and be completely illuminated without dark spots.
Solution Approach 2:
The patent introduces a notch in the elbow as an intermediary space that accommodates the connectors. This notch acts as a mediator between the wire protector and the LED strip housing area, providing a dedicated space for connectors that does not interfere with the LED strip's full illumination and extension to the profile end.
