Hoisting Assembly with Multi-Line Suspension and Cargo Net
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hoisting assemblies lack a configuration with multiple lines engaged to a hoist, each with a coupler for beam attachment, and a cargo net with closable slits for secure load engagement and positioning.
Innovation Solution
A hoisting assembly comprising a housing with a drum or lift wheel, a suspension module with lines and couplers for beam engagement, and a connector with a cargo net and cables for load lifting, allowing secure attachment and positioning of loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hoisting assembly uses a single attachment point, then the device complexity is reduced, but the reliability and stability of load lifting deteriorates
Solution Approach 1:
The hoisting assembly is divided into multiple independent lines (first line, second line, third line) each with its own coupler, allowing the system to distribute load across multiple attachment points while maintaining modular simplicity in each individual component
Solution Approach 2:
The couplers are nested within the housing structure, with each coupler positioned to receive a respective line that extends into the housing interior, creating a compact integrated assembly that reduces overall complexity while maintaining multiple attachment points
2Ease of operation
If a cargo net uses open design, then the ease of operation for loading/unloading is improved, but the security and stability of load engagement deteriorates
Solution Approach 1:
The cargo net features closable slits that can be opened for loading/unloading operations and closed for secure transport, transforming the net from a static open structure to a dynamic system that adapts its configuration based on operational requirements
Solution Approach 2:
The slits are pre-positioned in the cargo net to allow easy access for loading and unloading, and the closing mechanism is pre-configured to secure the load before lifting, ensuring both ease of operation and security are addressed in advance

AI summary
A hoisting assembly for lifting a load into an attic or lowering a load therefrom includes a hoist. The hoist comprises a housing, which has a drum or a lift wheel engaged thereto and positioned in an interior space defined thereby. A suspension module is engaged to and extends from an upper end of the housing. The suspension module can selectively engage a beam so that the housing is suspended from and removably engaged to the beam. A lifting medium is operationally engaged to the drum or the lift wheel and extends from a lower end of the housing. A connector is engaged to the lifting medium distal from the housing. The connector can selectively engage a load so that the load is removably engaged to the lifting medium. The hoist thus is configured to lift the load.
