Wire Bundle Assembly Transport via Pivot Dolly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly and installation of large wire bundle assemblies in aircraft require extensive manual labor, leading to inefficiencies and increased time due to the size and weight of the bundles, which necessitate significant manpower and complex handling procedures.
Innovation Solution
A method and system utilizing a fabrication table with pivotable assembly panels and a transport tool with a WBAG receiving panel to assemble and transport wire bundle assemblies efficiently, reducing manual labor by allowing the assemblies to be rotated and transferred using a pivot mechanism and adjustable supports, enabling easier handling and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wire bundle assemblies are manually transported and installed by installers carrying them on shoulders, then the WBAG can be moved from assembly area to installation site, but the manual labor requirements increase significantly and installation time increases
Solution Approach 1:
A dolly device serves as an intermediary tool between the assembly area and installation site. The dolly includes a platform for receiving the WBAG, a handle for maneuvering, and a pivot mechanism for rotation. This intermediary device eliminates the need for installers to carry heavy WBAGs on their shoulders, reducing manual labor and fatigue while enabling efficient transport and installation.
2Reliability
If wire bundle assemblies are made long and heavy to accommodate complex electrical systems, then the electrical system requirements are met, but the weight and handling difficulty increase
Solution Approach 1:
The dolly device incorporates a pivot mechanism that allows the platform to rotate 360 degrees. This dynamic feature enables installers to easily reorient the long WBAG during transport and installation without manual handling. The pivot mechanism converts the static heavy object into a dynamically manageable assembly, reducing handling difficulty while maintaining the complete electrical system requirements.
3Ease of operation
If multiple installers are used to carry and install the WBAG, then the weight can be distributed, but the coordination complexity and installation time increase
Solution Approach 1:
The dolly device with its handle and pivot mechanism serves as a mechanical intermediary that simplifies the installation procedure. Instead of coordinating multiple installers to manually lift and position the WBAG, a single installer can maneuver the dolly with ease. The pivot mechanism automatically handles the complex reorientation task, reducing coordination complexity while maintaining handling ease.
4Ease of manufacture
If the WBAG is assembled in a location remote from the aircraft fuselage, then the assembly can be completed with proper equipment, but the transportation distance and manual handling increase
Solution Approach 1:
The dolly device enables the assembled WBAG to be dynamically transported from the remote assembly location to the aircraft fuselage. The pivot mechanism allows the long WBAG to be easily rotated and maneuvered during transport, reducing the effective handling distance and effort required. This dynamic transport solution maintains assembly feasibility while minimizing the impact of transportation distance.

AI summary
A method for assembling and installing a wire bundle assembly group (WBAG) is disclosed. The method includes placing a first grouping of components of a first WBAG on a first assembly panel of a fabrication table. The method also includes assembling the first WBAG from the first grouping of components and attaching the first WBAG to the first assembly panel. The method also includes actuating a pivot of an assembly frame supporting the first assembly panel to rotate the first assembly panel about a longitudinal axis. The method further includes placing a WBAG receiving panel of a transport tool adjacent the first WBAG and the first assembly panel. The method also includes releasing the first WBAG from the first assembly panel and dropping the WBAG onto the WBAG receiving panel. Finally, the method includes attaching the first WBAG to the WBAG receiving panel.
