Cab Pivot Recess Routing Connecting Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for connecting a driver's cab to a vehicle frame result in significant lengthening or shortening of connecting lines during pivoting, which can lead to collisions and damage, and lack a space-saving arrangement.
Innovation Solution
A device featuring recesses in the side member of the vehicle frame to route connecting lines close to the pivot axis, minimizing line length changes and using flexible lines and holding elements to secure them within these recesses, preventing damage and collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If connecting lines are routed away from the pivot axis, then the arrangement is simpler, but the lines experience significant lengthening and shortening during pivoting
Solution Approach 1:
The patent introduces a cable holder as an intermediary component that mediates between the pivot axis and the connecting lines. This holder is designed to rotate with the cab while maintaining a consistent distance from the pivot axis, serving as a stable anchor point for the lines and preventing them from experiencing excessive length changes during pivoting.
Solution Approach 2:
The patent routes the connecting lines through a three-dimensional path that combines radial and tangential components relative to the pivot axis. By using a cable holder positioned at a specific radius from the pivot axis, the lines follow a circular arc path during rotation, which minimizes length changes compared to straight-line routing.
2Reliability
If additional lengths are reserved for connecting lines, then lengthening and shortening is compensated, but the arrangement becomes less space-efficient
Solution Approach 1:
The patent optimizes the parameters of the cable holder, including its radial distance from the pivot axis and the routing angle of the connecting lines. By carefully selecting these parameters, the system achieves effective compensation for line length changes during pivoting while minimizing the additional space required compared to conventional routing methods.
3Reliability
If connecting lines are routed close to the pivot axis, then lengthening and shortening is minimized, but the arrangement becomes more complex
Solution Approach 1:
The patent divides the routing system into distinct segments: the pivot axis, the cable holder, and the connecting lines. This segmentation allows each component to be optimized independently - the cable holder handles the rotational movement while the lines maintain a stable length, simplifying the overall design despite the proximity to the pivot axis.
4Ease of manufacture
If connecting lines are exposed during pivoting, then installation is easier, but collisions and damage can occur
Solution Approach 1:
The patent nests the connecting lines within a protective cable holder structure that rotates with the cab. This nested arrangement protects the lines from external collisions and damage while maintaining ease of installation, as the holder itself serves as a protective conduit during the pivoting operation.
