Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable routing systems in articulated vehicles are prone to damage due to incorrect installation, especially when using guide rails, and fail to ensure stable and reliable operation of cables during vehicle movements.
Innovation Solution
A cable routing system for articulated vehicles with end and intermediate cable clamps that allow for horizontal and rotational displacement, using a center frame and intermediate holders to guide cables without a continuous guide rail, ensuring flexible and secure cable support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a guide rail is used to support cables running from one articulated vehicle section to another, then the cables are supported along the vehicle joint, but the cable or the spring steel may be damaged if it is installed incorrectly
Solution Approach 1:
The cable routing system is divided into multiple independent cable clamps (first cable clamp, second cable clamp, third cable clamp) positioned at different locations along the vehicle joint. Each clamp independently supports sections of the cable, eliminating the need for a continuous guide rail and reducing the risk of damage from incorrect installation of a single long component.
Solution Approach 2:
The cable clamps act as intermediary support elements between the cable and the vehicle structure. Instead of a continuous guide rail directly supporting the cable along its entire path, discrete clamps provide localized support points, reducing stress concentration and damage risk.
2Ease of operation
If a guide rail follows all or a large part of the cable route along the vehicle joint, then the cables are supported, but incorrect installation may lead to damage
Solution Approach 1:
The routing system uses multiple discrete cable clamps rather than a single continuous guide rail. This segmentation allows for easier installation and adjustment of individual clamp positions while maintaining overall cable support, improving both ease of operation and reliability.
Solution Approach 2:
The cable clamps are designed to be movable along the vehicle joint axis, allowing dynamic adjustment to accommodate different cable lengths and routing requirements. This dynamic positioning capability enables flexible installation while ensuring reliable cable support during vehicle operation.
3Adaptability or versatility
Cables routed along the vehicle's articulation have different diameters, stiffness, and mechanical strengths, requiring flexible routing adaptation
Solution Approach 1:
The cable clamps are designed as universal support elements that can accommodate cables with different diameters, stiffness, and mechanical strengths. Each clamp provides multi-functional support including lateral positioning, axial adjustment, and rotational freedom, allowing a single clamp design to handle various cable types without increasing system complexity.
Solution Approach 2:
The cable clamps incorporate dynamic characteristics with movable positions along the vehicle joint and rotational freedom about vertical axes. This allows the routing system to adapt to different cable properties and vehicle movement conditions without requiring complex fixed structures for each cable type.
