Modular Cable Routing Duct for Commercial Vehicle Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for routing cables in commercial vehicles result in unsorted, unprotected bundles that are difficult to trace and prone to chafing and environmental damage, requiring numerous assembly steps and lacking modularity.
Innovation Solution
A device with a contact surface having recesses for parallel fastening of cables, connected to the vehicle frame via connecting elements, forming a cable duct that allows for preassembly and easy access, featuring modular design and protection for cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cables are laid directly on the frame using cable ties and brackets, then installation is simple, but cables become unsorted, unprotected, and difficult to trace
Solution Approach 1:
The cable routing system is divided into modular cable routing units that can be independently installed and configured. Each unit contains integrated holders for different cable types, allowing the system to be segmented into manageable sections rather than one complex continuous routing system
Solution Approach 2:
Multiple cable holding functions are merged into a single integrated cable routing unit. The unit combines holders for power cables, signal cables, and other cable types, along with protective channels and mounting features, replacing multiple separate brackets and cable ties
2Productivity
If cables are bundled together with cable ties, then installation is quick, but cables are exposed to environmental influences and chafing
Solution Approach 1:
The cable routing units incorporate protective channels and cover elements that enclose cables, shielding them from environmental influences such as moisture, dust, and mechanical chafing while maintaining flexibility for cable movement and installation
3Ease of manufacture
If multiple types of holders are used to fasten cables, then cables can be secured, but tracing individual lines becomes difficult
Solution Approach 1:
The cable routing units provide universal mounting features and standardized holder designs that can accommodate different cable types within a single integrated structure, making installation consistent across various cable configurations while maintaining traceability
Solution Approach 2:
Different holder types within the cable routing units are distinguished by color coding, allowing installers and maintenance personnel to quickly identify and trace specific cable types and their routing paths without confusion
4Ease of manufacture
If cables are routed without a structured system, then assembly is simple, but service and maintenance are difficult
Solution Approach 1:
The cable routing system is segmented into discrete, modular units that can be independently accessed, removed, or replaced. This segmentation allows maintenance personnel to service specific cable sections without disturbing the entire routing system
Solution Approach 2:
The cable routing units incorporate dynamic features such as adjustable holders and flexible mounting configurations that allow easy reconfiguration during maintenance operations, enabling cables to be accessed, replaced, or rerouted with minimal effort

AI summary
A technology for routing cables and pipes in a commercial vehicle is described. With regard to a device aspect of the technology, a device (100) comprises at least one contact surface (102) against which longitudinally extending cables (104) rest or can be brought into contact. A longitudinal dimension (106) of the contact surface (102) is greater in the longitudinal direction than a transverse dimension (108) of the contact surface (102) perpendicular to the longitudinal direction. The contact surface (102) has a plurality of recesses (110) for attaching the cables (104) to the contact surface (102) by means of fastening elements (112) engaging in a subset of the recesses (110). Furthermore, the device (100) comprises connecting elements (114) by means of which the device (100) is connected or connectable at several points to at least a section of a frame of the commercial vehicle.
