Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sleeves for spooling drums are inflexible and costly to manufacture, making them unsuitable for drums with varying diameters, and they fail to accommodate slight dimensional uncertainties during the manufacturing process, leading to inefficiencies in cable spooling.
Innovation Solution
A flexible sleeve made of materials like PVC, which can transform from a flat sheet with grooves into a cylinder, accommodating different drum diameters and heights, with a manufacturing process that uses the same tools for various sizes, allowing easy fitting and adjustment to ensure smooth cable spooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid sleeve is used for spooling drums, then the structural stability is improved, but the adaptability to different drum diameters deteriorates
Solution Approach 1:
The patent applies a flexible sleeve made of elastomeric material that can deform to accommodate different drum diameters while maintaining structural integrity during cable spooling operations. The flexibility allows the sleeve to adapt to dimensional variations in drums without requiring rigid structural components.
Solution Approach 2:
The sleeve's physical parameters (shape, volume, surface area) change dynamically as it deforms around drums of different diameters. The elastomeric material allows the sleeve to transition between different configurations while maintaining its functional properties for cable support and guidance.
2Manufacturing precision
If a customized sleeve is manufactured for each drum size, then the manufacturing precision is improved, but the manufacturing cost increases
Solution Approach 1:
The patent describes a universal sleeve design that can be used across multiple drum sizes within a range. The flexible elastomeric construction allows a single sleeve type to serve multiple drum configurations, eliminating the need for customized sleeves for each drum size while maintaining adequate precision for cable spooling.
Solution Approach 2:
The sleeve's dimensional parameters are designed to accommodate a range of drum diameters through elastic deformation. This allows a single manufacturing process to produce sleeves that can adapt to different drum sizes without requiring precision customization for each application.
3Adaptability or versatility
If a flexible material is used for the sleeve, then the adaptability to different drum diameters is improved, but the structural stability deteriorates
Solution Approach 1:
The elastomeric material's physical parameters (stiffness, elasticity, dimensional stability) are specifically selected to provide both flexibility for adaptation and sufficient structural stability for cable support. The material properties are engineered to maintain functional stability while allowing necessary deformation.
Solution Approach 2:
The flexible elastomeric sleeve is designed with specific thickness and material properties that balance flexibility and structural integrity. The shell structure provides sufficient rigidity to support cable loads while maintaining the flexibility needed to accommodate drum dimensional variations.

Function Achieved in This Case
The flexible sleeve ensures efficient cable spooling on drums with varying diameters, reduces manufacturing costs, and adapts to minor dimensional variations, providing a cost-effective and reliable solution for cable deployment in boreholes.
Implementation Method 1
The sleeve is made of flexible material and takes a first configuration in which it forms a flat sheet, and a second configuration in which it forms a cylinder
Data Source
AI summary
The disclosure relates to a sleeve for fitting around a spooling drum: the sleeve comprises at least a groove for receiving a conveying element to be spooled around the drum, is made of flexible material and is configured so as to be able to take a first configuration in which the sleeve forms a flat sheet, the groove extending in a direction, called spooling direction, and a second configuration in which the sleeve forms a cylinder, with the groove is situated on an external face of the cylinder.
