Telescoping Jack Apparatus for Heavy Spool Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional material handling apparatuses struggle to lift and support large, heavy spools of windable materials, which are often too heavy for manual handling or conventional stands, and lack durability for forklift transport.
Innovation Solution
A modular jack apparatus with adjustable telescoping post assemblies and reinforced frame, capable of lifting and supporting spools of varying sizes, equipped with wheels for mobility and a forklift attachment for heavy loads, and an optional motor for spool rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional stands are used to lift spools, then the spool can be elevated for material winding, but the apparatus cannot handle heavy spools that exceed manual lifting capacity
Solution Approach 1:
The apparatus is divided into two main sections (first section and second section) that can independently support each spool end. Each section has its own post assembly and jack, allowing the system to handle heavy spools by distributing the load across multiple independent support points rather than requiring a single monolithic structure.
Solution Approach 2:
The post assemblies are designed to be telescoping and adjustable in length, allowing the apparatus to adapt to spools of varying sizes and weights. The jacks provide dynamic height adjustment capability, enabling the system to accommodate different loading conditions and spool configurations while maintaining structural integrity.
2Weight of moving object
If the apparatus is designed to lift heavy spools, then it gains lifting capacity, but it becomes difficult to move the apparatus itself across the floor
Solution Approach 1:
The apparatus incorporates removable wheel assemblies that can be attached to or removed from the first and second sections. When wheels are attached, the apparatus can be easily moved across the floor to reposition heavy spools. When wheels are removed, the apparatus provides stable ground contact for heavy lifting operations, preventing the apparatus itself from becoming unstable under heavy loads.
Solution Approach 2:
The wheel assemblies are designed to be selectively removable, allowing the apparatus to dynamically switch between mobile and stationary configurations. This enables the system to adapt its mobility characteristics based on the operational phase: mobile during positioning and stationary during heavy lifting.
3Reliability
If the apparatus is built with reinforced components for durability, then it can withstand heavy loads and forklift transport, but the structure becomes more complex
Solution Approach 1:
The frame is segmented into modular first and second sections that can be independently reinforced. Each section has its own post assemblies and support structures, allowing reinforcement to be applied only where needed for heavy load handling rather than strengthening the entire apparatus uniformly. This modular approach maintains durability while reducing overall structural complexity.
Solution Approach 2:
The frame sections are designed with universal reinforcement features that serve multiple functions: they provide structural strength for heavy spool support, enable forklift attachment points for transport, and maintain stability during operation. This multi-functionality reduces the need for separate specialized components, thereby reducing overall complexity while maintaining durability.
4Adaptability or versatility
If the apparatus is designed for fixed spool sizes, then the structure can be simplified, but it cannot accommodate spools of varying diameters and widths
Solution Approach 1:
The post assemblies are designed to be telescoping with adjustable lengths, allowing each post to be independently extended or retracted to accommodate spools of varying diameters. The jacks provide additional dynamic adjustment capability for height and positioning. This dynamic adjustability enables the apparatus to handle a wide range of spool sizes without requiring complete structural reconfiguration.
Solution Approach 2:
The apparatus uses independent adjustable post assemblies for each spool end, allowing each side to be independently configured for different spool dimensions. This segmentation of adjustment mechanisms enables versatile spool accommodation while keeping each individual adjustment system relatively simple rather than requiring a single complex universal adjustment mechanism.

AI summary
Apparatus for lifting and supporting an item above a floor includes a frame and a pair of upright telescoping post assemblies having two opposite ends and which are positionable on opposite sides of the item to be lifted. A pair of guide posts are arranged as to extend substantially vertically of the frame and adjacent the post assemblies. A carriage assembly is mounted upon each post assembly for cooperating between the item and an adjacent guide post, and jacks are utilized for moving the ends of the post assemblies apart so that by positioning the carriage assemblies in cooperating relationship with the item and moving the ends of the post assemblies apart, the item is lifted by a corresponding amount and the carriage assemblies are guided along the guide posts.
