Cable Duct Assembly With Integrated Cover-Wall Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable duct assemblies require cumbersome assembly processes and additional connecting devices, which can hinder cable laying and complicate the creation of customized chamber layouts for varying cable types and cross-sections.
Innovation Solution
A cable duct assembly with a one-piece connecting device integrated into the cover wall of each channel body, allowing for external positive connections without penetrating the channel walls, enabling easy assembly and flexible configuration without external connecting devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external connecting devices (clamps, screws) are used to assemble cable ducts, then the cable ducts can be connected to form assemblies, but the assembly process becomes cumbersome and requires additional components
Solution Approach 1:
The connecting device is merged with the cable duct body to form an integrated structure. The connecting device is formed in one piece on a cover wall of the channel body, eliminating the need for separate external connecting components and simplifying the assembly process
2Strength
If connecting screws penetrate the duct wall to connect cable ducts, then the ducts can be securely connected, but the interior space for cables is reduced and cable laying is hindered
Solution Approach 1:
The connecting device is extracted from the interior space of the cable duct and positioned externally on the cover wall. The connecting device forms an external form-fitting connection that does not penetrate the duct wall, ensuring that the space available for accommodating cables is not impaired
3Adaptability or versatility
If multiple differently dimensioned multi-chamber cable ducts are kept in stock to provide various chamber layouts, then customized configurations can be achieved, but the stockpiling becomes complex
Solution Approach 1:
The cable duct design with standardized cross-sections and integrated connecting devices enables universal applicability. Cable ducts can be combined in different numbers and configurations to provide sufficient overall capacity for various cable installation requirements, eliminating the need to maintain complex inventories of specialized duct types
4Ease of operation
If cable ducts are combined using force-fit connections by screwing duct walls together, then the ducts can be connected, but the installation becomes cumbersome and time-consuming
Solution Approach 1:
The connecting device is pre-formed as an integral part of the cable duct body during manufacturing. This preliminary integration eliminates the need for separate assembly steps involving external connecting devices, making the installation process simpler and faster
