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, and a fixing structure with straight line segments and a wire crimping member for secure attachment, preventing detachment and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the wire harness structure is rigidly connected to adjacent vehicle bodies, then the structural strength is improved, but the wire harness structure is prone to breakage due to repeated bending when vehicle bodies are at an included angle
Solution Approach 1:
The wire harness structure is divided into multiple segments: rigid connecting portions for structural strength and elastic deformation portions for flexibility. The elastic deformation portion is positioned at the junction of adjacent vehicle bodies to accommodate angular changes, while the rigid portions maintain structural integrity elsewhere in the system.
Solution Approach 2:
Different portions of the wire harness structure have different mechanical properties. The elastic deformation portion has high flexibility to accommodate bending, while other portions maintain rigidity for structural support. This localized differentiation of material properties resolves the contradiction between overall strength and local flexibility needs.
2Adaptability or versatility
If the wire harness structure allows flexible connection between vehicle bodies, then the operational adaptability is improved, but the wire harness structure becomes prone to breakage and has short service life
Solution Approach 1:
The wire harness is segmented into elastic deformation portions at vehicle body junctions and rigid portions in other areas. The elastic segments provide the necessary flexibility for operational adaptability when vehicle bodies are at included angles, while the rigid segments maintain structural integrity to ensure long service life.
Solution Approach 2:
The elastic deformation portion acts as a pre-designed cushioning element that absorbs bending stresses before they can propagate through the entire wire harness structure. This beforehand cushioning prevents breakage and extends service life while maintaining operational flexibility.
3Stability of the object's composition
If the wire harness structure is fixed rigidly, then the structural stability is improved, but the bending forces cause repeated stress and reduce operational stability
Solution Approach 1:
The wire harness structure is segmented into rigid portions for structural stability and elastic deformation portions positioned at vehicle body junctions. The elastic segments absorb bending forces during turns, preventing stress propagation that would compromise operational stability, while rigid portions maintain overall structural integrity.
Solution Approach 2:
Different portions of the wire harness have different mechanical characteristics tailored to their functional requirements. The elastic deformation portion provides local flexibility to handle bending forces during vehicle body articulation, while other portions maintain rigidity for structural stability, resolving the contradiction between these two stability requirements.
