Vehicle Wire Harness Tagging for Faster Chassis Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of wire harnesses in vehicles is a tedious and time-consuming process due to the complexity of interconnecting multiple sections, cross-connections, and connectors, necessitating a method to simplify the identification and assembly process.
Innovation Solution
The use of identifier tags, such as visual fiducial tags (e.g., AprilTags) and electronic communication devices, is applied to both the wire harness and chassis to facilitate the identification and assembly of wire harness sections and receptacle areas, enabling automated or manual guidance during the installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If identifier tags are attached to wire harness sections and receptacle areas, then the identification and assembly process is simplified and automated guidance is enabled, but the device complexity increases due to additional tags and communication devices
Solution Approach 1:
Visual fiducial tags and electronic communication devices serve as intermediaries between the wire harness system and the installation/automation system. These tags mediate the identification and positioning process, enabling automated systems to detect and guide harness installation without requiring complex manual procedures
Solution Approach 2:
The patent replaces manual mechanical identification and positioning methods with optical (visual fiducial tags) and electronic (communication devices) systems. This substitution enables automated detection and guidance, reducing reliance on tedious manual unfolding, flipping, and pulling operations
2Manufacturing precision
If multiple identifier tags are attached to sections and connectors of the wire harness, then the precision of identifying and assembling specific sections is improved, but the time and labor required for tagging and assembly increase
Solution Approach 1:
Identifier tags are attached to wire harness sections and receptacle areas during manufacturing, before installation. This preliminary action ensures that all identification markers are already in place, eliminating the need for time-consuming tagging operations during the installation process and enabling immediate automated detection and guidance

AI summary
A process and method for tagging identifiers in an automotive wire harness for recognition and installation. The process and method include attaching a plurality of first identifier tags to a wire harness, where each of the plurality of first identifier tags identifies a section of the wire harness. Continuing and identifying, based on the plurality of first identifier tags, a plurality of sections of the wire harness is accomplished. The wire harness is prepared for assembly into an automotive chassis, where the preparing includes, by section, an unfolding, flipping, or pulling of the wire harness, based on the plurality of first identifier tags. The process and method include attaching a plurality of second identifier tags to the automotive chassis, where each of the plurality of second identifier tags identifies a corresponding receptacle area associated with the one or more of the first identifier tags.
