Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable ladders with long crosspieces are difficult to handle, store, and transport due to their large width, occupying considerable space and posing challenges in assembly and disassembly.
Innovation Solution
A cable ladder design featuring two coplanar side rails and intermediate half side rails made of polymeric material, allowing the ladder to be separated into two halves for easier assembly and disassembly, with crosspieces fitting directly or through a connecting piece into the side rails, enabling stable support and simplified handling and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If cable ladders with long crosspieces are used to achieve large width, then the cable ladder can support more cables and provide wider coverage, but the cable ladder occupies considerable space and becomes difficult to handle, store, and transport
Solution Approach 1:
The cable ladder is divided into two separate halves, each containing one side rail and associated crosspieces. This segmentation allows the cable ladder to be transported in a compact state and assembled on-site, resolving the contradiction between achieving large width and maintaining ease of handling.
2Stability of the object's composition
If cable ladders with long crosspieces are assembled as complete units, then the structure is stable and rigid, but the assembly process becomes complex and time-consuming
Solution Approach 1:
By segmenting the cable ladder into two pre-assembled halves that can be independently manufactured and transported, the overall assembly time is reduced while maintaining structural stability through the connection of the two halves at the installation site.
3Strength
If the cable ladder is designed as a single integrated unit, then the structure achieves maximum rigidity, but the risk of damage during handling and transportation increases
Solution Approach 1:
Dividing the cable ladder into two smaller, more manageable halves reduces the risk of damage during handling and transportation. The connection between halves is designed to maintain structural rigidity when assembled, thus resolving the contradiction between strength and damage risk.
4Device complexity
If standard cable ladder components are used, then the design is simple and cost-effective, but the adaptability to different installation requirements is limited
Solution Approach 1:
The two half-side rails are designed with universal connection features that allow them to be assembled in different configurations (e.g., parallel, angled, or perpendicular arrangements). This universality provides adaptability to various installation requirements while maintaining design simplicity through standardized components.

AI summary
The invention relates to a cable ladder (1) comprising two coplanar side rails (2) and a plurality of crosspieces (3) forming a discontinuous support surface for cables. The ends of the crosspieces (3) fit in an inner side (4) of the side rails (2) facing an inner side (4) of the opposite side rail (2). The cable ladder (1) comprises an intermediate side rail (5) arranged between the two side rails (2). The intermediate side rail (5) is formed by two half side rails (6) which are assembled together. Each of the two half side rails (6) comprises a first side (7) in which the ends of the crosspieces (3) fit and a second side (8), opposite the first side (7), which fits in the second side (8) of the other one of the half side rails (6) so as to form the intermediate side rail (5). The crosspieces (3), the side rails (2), and the half side rails (6) are profiles made of a polymeric material.
