Lifting Device Quick Clamp for Interchangeable Cargo Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting arrangements for lorries lack versatility and efficiency in handling different types of cargo without requiring modifications to the hoist or lifting device, limiting their multipurpose capabilities.
Innovation Solution
A lifting device with a frame, forks, and a quick clamp that allows easy attachment and detachment of various lifting members such as buckets, grabs, or claws, enabling the handling of diverse cargo without needing different hoists or lifting devices, and featuring a turnable frame for balanced operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed lifting device is used, then the device structure is simple, but the versatility for handling different cargo types is limited
Solution Approach 1:
The lifting device is designed with a universal frame structure that can accommodate multiple types of lifting members (forks, grabs, buckets, claws) through a standardized quick clamp interface. This allows a single lifting device to perform multiple cargo handling functions without requiring separate specialized equipment for each cargo type.
Solution Approach 2:
The lifting device is divided into separable components: a permanent frame structure and interchangeable lifting members. The quick clamp mechanism enables easy detachment and replacement of lifting members, allowing the system to be reconfigured for different cargo types while keeping the main hoist and frame structure.
2Adaptability or versatility
If multiple specialized lifting devices are used for different cargo types, then the versatility is improved, but the device complexity and number of components increases
Solution Approach 1:
Instead of deploying multiple specialized lifting devices, the invention implements a single lifting device with universal capabilities through the quick clamp system. This reduces the total number of lifting devices needed while maintaining the ability to handle various cargo types by simply changing the lifting member attachment.
3Productivity
If lifting members are permanently fixed to the frame, then the structure is stable, but the time required to change lifting members increases
Solution Approach 1:
The quick clamp mechanism is pre-designed with alignment features and engagement points that guide the lifting member into the correct position during attachment. This preliminary design of the connection interface enables rapid coupling without requiring complex alignment procedures or multiple adjustment steps, significantly reducing the time to change lifting members.
4Adaptability or versatility
If the frame structure is fixed and non-adjustable, then the manufacturing is simpler, but the adaptability for different lifting configurations is reduced
Solution Approach 1:
The frame incorporates adjustable elements such as movable sections and reconfigurable support structures that can be positioned in different configurations depending on the type of lifting member attached. This dynamic adjustability allows the frame to adapt to various lifting geometries and cargo requirements while maintaining a relatively simple base structure that can be manufactured efficiently.
