Sorting Vehicle Wire Harness Structure for Repeated Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wire harness structure in sorting vehicles and machines is prone to breakage due to repeated bending when the vehicle bodies are not in a straight line, leading to a short service life and poor operational stability.
Innovation Solution
Incorporating an elastic deformation portion in the wire harness structure at the junction of adjacent vehicle bodies, which allows for elastic deformation during turns, dispersing bending forces and preventing hard bending, along with a fixing structure using straight line segments and a wire crimping member for secure attachment to the vehicle bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the wire harness structure is rigidly connected to adjacent vehicle bodies, then the connection is stable and secure, but the wire harness structure is prone to breakage due to repeated bending when vehicle bodies are at included angles
Solution Approach 1:
The wire harness structure is divided into multiple segments: rigid connecting portions for stable attachment to vehicle bodies, and a flexible bending portion in between that can accommodate angular changes. This segmentation allows different parts to serve different functions - the rigid parts provide stable connection while the flexible part prevents breakage during turning operations
Solution Approach 2:
The wire harness structure changes its geometric parameters dynamically - it maintains a straight configuration when vehicle bodies are aligned, but allows the bending portion to form angles when vehicle bodies are at included angles. This parameter change enables the structure to adapt to different operational states without causing damage
2Reliability
If the wire harness structure allows flexible movement between vehicle bodies, then bending damage is reduced, but the connection stability and signal transmission reliability may be compromised
Solution Approach 1:
The wire harness is segmented into flexible and rigid portions, where the flexible bending portion accommodates movement to prevent damage, while the rigid connecting portions maintain stable connections at the vehicle body interfaces. This segmentation resolves the contradiction by localizing flexibility where needed while preserving stability at connection points
Solution Approach 2:
The flexible bending portion acts as an intermediary element between the rigid connecting portions that attach to adjacent vehicle bodies. It mediates the mechanical stress and angular changes, absorbing the flexibility needed to prevent breakage while allowing the rigid connection portions to maintain stable attachments
