Hoist Frame Clamping Layout for Load-Free Jig Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hoist tools attached to assembled structures in a cantilevered fashion induce load, causing structural strain and damage during extraction from assembly jigs.
Innovation Solution
A hoist tool with structure-attachment elements and a hoist frame that removably couple to both the assembly jig and the assembled structure, using clamping devices with adjustable blade features to secure the structure without imparting load, supported by the jig.

Engineering Contradiction Analysis
1Reliability
If the hoist tool is attached to the assembled structure in a cantilevered fashion, then the hoist tool can be securely attached to the structure, but the weight of the hoist tool imparts load to the assembled structure causing structural strain and damage
Solution Approach 1:
The assembly jig serves as an intermediary element that supports the hoist frame, thereby preventing the hoist tool's weight from being transmitted to the assembled structure. The jig acts as a mediator between the hoist tool and the structure, bearing the load during the extraction process.
Solution Approach 2:
The hoist tool is divided into two separate attachment systems: one that attaches to the assembly jig (via jig-attachment features) and another that attaches to the assembled structure (via clamping devices). This segmentation allows the load-bearing function to be separated from the structure-attachment function.
2Object-affected harmful factors
If the hoist frame is supported by the assembly jig, then the assembled structure is protected from load, but the device complexity increases due to additional attachment mechanisms
Solution Approach 1:
The hoist frame incorporates multiple attachment features that serve different functions: jig-attachment features for securing to the assembly jig and clamping devices for securing to the assembled structure. These multi-functional features allow a single device to perform both load-bearing and structure-attachment roles without requiring separate systems.
Solution Approach 2:
The clamping devices feature selectively adjustable opposing blade features that can be dynamically positioned to accommodate different structure geometries. This adjustability provides adaptability without requiring multiple specialized attachment mechanisms for different structure types.

AI summary
Disclosed herein is a hoist tool and associated system and method. The hoist tool includes a plurality of structure-attachment elements, each having a sleeve with an external annular groove, and configured to be attached to an assembled structure within an assembly jig at distinct locations. The hoist tool also includes a hoist frame. The hoist frame includes a structural framework, a plurality of jig-attachment features on the structure framework, and a plurality of clamping devices having opposing blade features that are configured to removably clamp to the external annular groove of a corresponding one of the plurality of structure-attachment elements. The hoist frame is configured to be removably coupled to the assembly jig, via the plurality of jig-attachment features and removably coupled to the assembled structure, via the plurality of clamping devices. When the hoist frame is removably coupled to the assembly jig and the assembled structure it is inhibited from imparting load to the assembled structure.
