Lifting Device With Variable Length Supports For Confined Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lifting and transporting devices face challenges in navigating through confined spaces, such as power station halls, due to the requirement for extensive space to position their supports, which limits their flexibility and ability to handle generators with elevated bases.
Innovation Solution
A lifting and transporting device with at least eight vertical supports of variable length, where four are designed as lifting supports and the remaining as support supports, allowing for adjustable lengths only when unloaded, enabling the device to 'climb' over height differences and operate directly on a base without requiring additional space for support setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lifting and transport devices use four vertical supports, then the device structure is simple, but the device cannot operate in confined spaces without additional support setup room
Solution Approach 1:
The device divides the support function into two distinct types: lifting supports (with variable length for height adjustment) and support supports (with fixed length for stability). This segmentation allows the four supports to perform different functions simultaneously, enabling operation in confined spaces without additional support setup while maintaining structural simplicity
Solution Approach 2:
The frame structure achieves multi-functionality by incorporating both lifting and support capabilities within the same four vertical supports. The lifting supports can extend and retract, while the support supports provide stable grounding, allowing the device to adapt to various operational environments including confined spaces without requiring additional components
2Adaptability or versatility
If the device uses variable length supports for lifting, then the device can handle height differences, but the device requires extensive space for support positioning
Solution Approach 1:
By separating the lifting function (variable length supports) from the support function (fixed length supports), the device can handle height differences through the lifting supports while the support supports minimize the space required for positioning. The support supports are designed to fit into recesses, reducing the footprint needed for stable operation
3Ease of manufacture
If the device uses fixed length support supports, then the manufacturing cost is reduced, but the device cannot adjust to varying heights
Solution Approach 1:
The device segments the support system into lifting supports with variable length (for height adjustment) and support supports with fixed length (for stable grounding). This segmentation allows the fixed support supports to be manufactured more simply and cheaply, while the lifting supports provide the necessary height adaptability through their variable length mechanism
Solution Approach 2:
Different parts of the support system have different properties: lifting supports are designed with variable length capability for height adjustment, while support supports are designed with fixed length for stability and cost-effectiveness. This local differentiation optimizes both manufacturing cost and height adaptability in their respective roles
