Wire Mesh Cable Tray Fixing Part with Rotating Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for fixing wire mesh cable trays on support bracket arms require screws and additional tools, are cumbersome, and do not effectively withstand seismic stresses, making them difficult to handle and install, especially at heights.
Innovation Solution
A fixing part with two tabs that can be rotated a quarter turn to slip under the edges of an opening, featuring a ramped section for easy insertion and a tensioning mechanism with V-folding to maintain the support wall, allowing for secure attachment without additional fasteners or tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixing parts with screws and nuts are used, then the cable tray section can be securely attached to the arm, but the installation process becomes cumbersome and requires additional tools and fasteners
Solution Approach 1:
The invention merges multiple functions into a single integrated fixing part. The fixing part includes a body with first and second arms that engage with the cable tray section, and a retention member that secures the assembly to the arm. This consolidation eliminates the need for separate screws, nuts, and washers, allowing installation without additional tools while maintaining secure attachment.
Solution Approach 2:
The fixing part is designed to be self-installing without requiring external fasteners or tools. The arms are deformable to allow insertion through the cable tray section, and the retention member automatically engages with the arm structure. The design enables the fixing part to secure itself to the arm through its own structural features, eliminating the need for additional fastening operations.
2Strength
If conventional fixing methods are used, then the connection can withstand static loads, but the connection fails to effectively resist seismic vibrations and relative movements
Solution Approach 1:
The fixing part incorporates dynamic characteristics through its deformable arms and retention member design. The arms can flex and deform during insertion and under load, allowing the connection to absorb and dissipate energy from seismic vibrations. The retention member engages in a manner that permits controlled movement while maintaining secure attachment, enabling the connection to withstand both static loads and dynamic seismic forces.
3Reliability
If multiple fasteners and tools are used for installation, then the connection can be securely made, but the installation process becomes time-consuming and difficult when working at height
Solution Approach 1:
The fixing part is designed to be self-installing without requiring external fasteners or tools. The arms are deformable to allow insertion through the cable tray section, and the retention member automatically engages with the arm structure. The design enables the fixing part to secure itself to the arm through its own structural features, eliminating the need for additional fastening operations.
Solution Approach 2:
The fixing part is pre-configured with its arms and retention member in positions that facilitate automatic engagement during installation. The arms are pre-deformed or designed to deform easily during insertion, and the retention member is positioned to automatically engage with the arm structure upon installation, eliminating the need for subsequent fastening operations.
