Modular Lifting Device Segmentation and Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting devices for big bags are heavy, bulky, and difficult to handle due to their welded construction, which limits their portability and increases storage space requirements and construction costs due to the need for weld testing.
Innovation Solution
A modular lifting device comprising two separable parts with a locking mechanism that can be connected and disconnected, allowing for compact storage and reduced volume when not in use, featuring a truss-like construction for strength and a locking system using pins or rings for secure assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If lifting devices are constructed with welded components to ensure strength and stability, then structural strength is improved, but the device becomes bulky and difficult to store when not in use
Solution Approach 1:
The lifting device is divided into multiple separable components that can be disconnected when not in use. The main body can be separated from extensions or attachments, allowing compact storage while maintaining structural integrity during operation. This segmentation enables the device to occupy minimal storage space while providing full functionality during lifting operations.
2Reliability
If lifting devices use welded construction to ensure reliability, then connection strength is improved, but the device becomes heavy and difficult to handle
Solution Approach 1:
Traditional welded mechanical connections are replaced with a locking mechanism system that uses geometric interlocking and locking elements rather than permanent welding. This substitution maintains connection reliability through positive locking while reducing the overall weight of the device, making it easier to handle and transport.
3Stability of the object's composition
If lifting devices are designed as integrated welded structures to ensure stability, then operational stability is improved, but the device becomes bulky for storage and transport
Solution Approach 1:
The lifting device is segmented into modular components that can be connected and disconnected. When assembled, the components form a stable structure suitable for lifting operations. When disconnected, the components can be stored compactly, significantly reducing storage volume while maintaining operational stability when needed.
Solution Approach 2:
The lifting device transitions from a static welded structure to a dynamic assembly that can be configured as needed. The locking mechanism allows the device to be assembled into a stable configuration for operation and disassembled for compact storage, providing dynamic adaptability between operational and storage states.
4Strength
If lifting devices use welded construction to ensure strength, then load-bearing capacity is improved, but construction costs increase due to required weld testing
Solution Approach 1:
Welded connections are replaced with a locking mechanism system that uses geometric interlocking, locking elements, and friction-based securing. This mechanical substitution eliminates the need for weld testing and associated costs while maintaining load-bearing capacity through positive locking and friction-based securement of the modular components.
