Trailer Connection Harness Assembly Effort Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection arrangements for trailer vehicles require significant effort to install, as individual lines need to be laid out and connected to various components, which is time-consuming and labor-intensive.
Innovation Solution
Combining lines into a common cable loom or harness, using holding means such as cable ties, clips, or adhesive, to reduce the assembly effort, allowing the lines to be integrated within a housing or formed before installation, thereby simplifying the mounting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual lines are laid out and connected to various components separately, then the connection arrangement can be customized for each component, but the installation effort and time required increase significantly
Solution Approach 1:
Multiple individual lines (electrical cables, pneumatic hoses, data cables) are merged into a single integrated cable loom that contains all necessary connections. This allows the entire connection arrangement to be installed as one unit rather than laying out each line separately, dramatically reducing installation time while maintaining all necessary customization options through the integrated structure.
Solution Approach 2:
The cable loom is pre-assembled with all lines, connectors, and routing pathways prepared before installation. This preliminary preparation includes pre-attaching connectors to the appropriate lines and pre-routing them through the trailer structure, so that during installation only the final connection to the towing vehicle is required, eliminating the time-consuming step-by-step line laying process.
2Productivity
If lines are combined into a common cable loom, then the assembly effort is reduced, but the complexity of the cable routing and integration increases
Solution Approach 1:
The cable loom is divided into modular sections or bundles, with different groups of lines (electrical, pneumatic, data) separated into distinct compartments or layers within the loom. This segmentation makes the complex routing manageable by allowing workers to handle and install different sections independently, reducing the perceived complexity during assembly while maintaining the integrated structure.
Solution Approach 2:
A central control unit or distribution box is introduced as an intermediary element that manages the connections between all lines in the cable loom and the various trailer components. This intermediary consolidates the complex routing logic into a single location, making the overall system easier to assemble and maintain while preserving the benefits of the integrated cable loom structure.
