Carriage system for cable ladders, cable raceways and cable trays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional carriage systems for cable ladders, cable raceways, and cable trays require numerous screw joints and tools for assembly, making the process time-consuming and involving extra components, which is inefficient and cumbersome.
Innovation Solution
A carriage system utilizing a pivot runner with a hole pattern and hook-shaped projections, along with spring lock tabs, allows for quick connection of components through a click-lock mechanism, minimizing the need for screw joints and tools, enabling faster assembly with fewer loose parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw joints are used to assemble carriage systems, then the connection is reliable, but the assembly process becomes time-consuming and requires numerous tools and components
Solution Approach 1:
The patent replaces the traditional screw joint mechanical system with a spring lock tab mechanism. The spring lock tab uses elastic deformation and snap-fit engagement to achieve reliable connections without requiring screws, nuts, or tools, thereby maintaining connection reliability while dramatically improving assembly speed
Solution Approach 2:
The spring lock tab is designed to automatically engage and lock components together through its own elastic properties. The tab bends during insertion and snaps into place, creating a self-locking connection that does not require external tools or additional fastening operations, thus eliminating the need for tools and reducing assembly time
2Reliability
If numerous screw joints and tools are used for assembly, then secure connections are achieved, but the number of loose parts and assembly complexity increases
Solution Approach 1:
The patent merges multiple separate components (screws, nuts, washers, and the tool required to assemble them) into a single integrated spring lock tab. This tab is pre-attached to the carriage component and performs both the fastening and locking functions in one piece, significantly reducing the number of loose parts while maintaining secure connections
Solution Approach 2:
The invention extracts and eliminates the unnecessary components from the traditional screw joint system. By removing screws, nuts, washers, and assembly tools, the design retains only the essential spring lock tab, which provides both connection and locking functions, thereby reducing complexity without compromising connection security
3Reliability
If lock tabs requiring tool intervention are used, then components are locked securely, but assembly time increases due to hand grip operations
Solution Approach 1:
The spring lock tab is designed to automatically perform the locking action through its own elastic properties. When inserted, the tab bends and snaps into the locking position without requiring any hand grip operations or tool intervention, thus maintaining secure locking while eliminating the time-consuming manual bending process
Solution Approach 2:
The patent replaces the manual tool-based locking mechanism with an automatic spring-loaded snap-fit system. The elastic deformation of the spring lock tab provides the necessary locking force without requiring external tools, thereby maintaining locking security while dramatically reducing assembly time by eliminating tool intervention
4Adaptability or versatility
If multiple varying components are used in carriage systems, then functional requirements are met, but the assembly procedure becomes complex and non-standardized
Solution Approach 1:
The spring lock tab is designed as a universal component that can be applied to various carriage system configurations and cable tray types. The standardized tab design maintains the ability to meet different functional requirements while providing a consistent, simple assembly procedure across all applications, thereby improving ease of operation without sacrificing adaptability
