Jig Assembly with Tensionable Straps for Fragile Component Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for handling and transporting large, fragile, and flexible component parts, such as aircraft fuselage panels, are complex, costly, and lack flexibility, especially when dealing with components that are not structurally strong, like glass or flexible coatings, as they require specialized and often expensive equipment with limited use in multiple stages of the manufacturing process.
Innovation Solution
A jig assembly comprising an elongate spar assembly with rib assemblies and tensionable strap assemblies, including a strap ratchet mechanism, is used to securely hold and position component parts, which can be coupled with a transport dolly for maneuvering and reorientation, allowing for secure handling and transport of large and fragile components across various manufacturing stages.

Engineering Contradiction Analysis
1Reliability
If specialized equipment such as treadmills, support cars, forklifts, cranes, and structures with suction and vacuum are used to handle large, fragile components, then the components can be transported and positioned, but the device complexity and cost increase significantly
Solution Approach 1:
The handling system is divided into modular components: a jig assembly with multiple rib assemblies that can be independently adjusted, and a transport dolly that separates the support function from the transport function. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining reliability for handling fragile components.
Solution Approach 2:
The jig assembly serves multiple functions: it supports the component during transport, positions it accurately, and can be reconfigured for different component sizes and shapes. The transport dolly provides both support and mobility functions. This multi-functionality eliminates the need for multiple specialized equipment types, reducing device complexity while ensuring reliable handling of fragile components.
2Adaptability or versatility
If conventional handling equipment is used for large components, then transport can be achieved, but the equipment lacks flexibility and adaptability across different manufacturing stages
Solution Approach 1:
The rib assemblies incorporate adjustable positioning mechanisms that allow dynamic reconfiguration to accommodate different component sizes, shapes, and weights. The jig assembly can be adapted throughout the manufacturing process from initial support to final positioning, providing flexibility without requiring multiple specialized equipment pieces, thus reducing manufacturing cost and complexity.
Solution Approach 2:
The jig assembly is pre-configured with multiple rib assemblies and support points that can be adjusted before each handling operation. This preliminary preparation allows the same equipment to be quickly adapted to different component requirements, enhancing versatility while avoiding the need for expensive specialized equipment for each specific task.
3Stability of the object's composition
If straps are used to secure components to cradle members and arcuate tubes, then the component is held in place, but the assembly cannot be positionally manipulated, making transportation difficult
Solution Approach 1:
The system separates the securing function (performed by straps on the jig assembly) from the transport function (performed by the transport dolly). The jig assembly with strapped component can be easily attached and detached from the dolly, enabling positional manipulation during transport while maintaining secure holding of the component throughout the process.
Solution Approach 2:
The transport dolly acts as an intermediary between the secured component assembly and the transportation system. The jig assembly with strapped component is attached to the dolly, which provides the mobility and maneuverability needed for transport while the straps maintain component stability. This intermediary allows both secure holding and easy positional manipulation.

AI summary
Assemblies and methods for the handling, transporting and/or positioning component parts include a jig assembly for supporting a component part is provided with an elongate spar assembly, a plurality of rib assemblies attached to the spar, and a plurality of tensionable strap assemblies operatively associated with the rib assemblies for capturing and holding the component part against the rib assemblies. The strap assemblies may include a strap ratchet mechanism and a strap, so that operation of the strap ratchet mechanism allows strap slack to be removed thereby tensioning the strap. The jig assembly may be positioned and oriented by suspension cables and a hoist mechanism to allow it to be removably connected to a moveable transport dolly.
