Trailer Coupling Line Fastening with Multi-Point Cable Tie Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing trailer coupling systems face challenges in efficiently routing and securing electrical lines between the vehicle and trailer, especially when the coupling arm is movably mounted, due to limited options for attaching cable ties, which complicates the assembly process and increases costs.
Innovation Solution
The trailer hitch incorporates multiple fastening strap retaining receptacles on the holding arm, allowing for various orientations and locations, enabling more flexible attachment of cable ties and supporting straps, thereby simplifying the routing and securing of electrical lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fastening strap mounting point is provided on the coupling arm, then the structure is simple, but the flexibility for routing electrical lines is limited
Solution Approach 1:
The single fastening mounting point is segmented into multiple fastening strap mounting points distributed at different locations and orientations on the coupling arm. This allows electrical lines to be routed and secured at multiple positions, providing greater flexibility without requiring a completely new fastening system.
Solution Approach 2:
The coupling arm is designed with multiple fastening strap mounting points that can accommodate various routing scenarios for electrical lines. These mounting points serve universal purposes for securing different components (electrical lines, cables, sensors) in multiple orientations and positions.
2Ease of manufacture
If cable ties are used to secure electrical lines along the hitch arm, then the electrical lines can be routed, but the assembly process becomes complicated with limited attachment options
Solution Approach 1:
The fastening strap mounting points are pre-integrated into the coupling arm structure during manufacturing. This preliminary action eliminates the need for additional attachment hardware or complex assembly steps, as the mounting points are already in place to receive cable ties or fastening straps.
Solution Approach 2:
The coupling arm provides its own fastening capability through integrated mounting points, eliminating the need for external fastening devices or complex attachment mechanisms. The structure serves itself by incorporating the necessary mounting features directly into the coupling arm.
