Integrated Load Balancing Hoist Module Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load balancing hoists are costly to produce due to their complex construction, which includes separate power and travel modules and multiple parts, making them inefficient in terms of manufacturing and space usage.
Innovation Solution
Combining the power module and travel module into a single unit by eliminating the piston rod and integrating one pulley within the end cap and the other within the piston, reducing the number of parts and chamber length, resulting in a compact and less costly hoist without sacrificing functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate power module and travel module are used, then operational reliability is improved, but device complexity and production cost increase
Solution Approach 1:
The patent combines the power module and travel module into a single integrated unit. The piston rod is eliminated and the pulley is integrated directly into the piston assembly, merging functions that were previously separated into distinct modules. This reduces the number of parts and simplifies the overall device structure while maintaining operational reliability through the unified design.
2Adaptability or versatility
If multiple parts and separate modules are used, then functional versatility is improved, but manufacturing cost and production complexity increase
Solution Approach 1:
The invention integrates multiple functions into a single compact unit. The piston assembly incorporates the pulley mechanism, and the housing contains both power and travel module functions. This consolidation reduces the number of separate parts that need to be manufactured and assembled, thereby reducing manufacturing cost and production complexity while preserving the hoist's functional versatility.
Solution Approach 2:
The integrated piston assembly serves multiple functions simultaneously: it acts as both the power transmission element and the travel module carrier, while the housing provides both structural support and guides the cable. This multi-functionality reduces the need for separate specialized components, simplifying manufacturing.
3Reliability
If piston rod and separate modules are used, then operational effectiveness is maintained, but space usage and compactness deteriorate
Solution Approach 1:
The patent eliminates the piston rod and integrates the pulley directly into the piston assembly. The travel module is merged with the power module, creating a compact unified structure. This integration significantly reduces the overall volume and space required for the hoist mechanism while maintaining operational effectiveness through the streamlined design.
