Web Tensioning Core with Coupled Handles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Applying a web around cylindrical objects like pipes with even tension is challenging due to the tendency of the web to bag in the center, resulting in uneven tension and potential leaks or structural integrity issues.
Innovation Solution
A system comprising a core with handles that have an insertion area, a collar area, and a gripping area, allowing the core and handles to couple and prevent independent movement, enabling even tension distribution when wrapping the web around the cylindrical object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a web is applied around a cylindrical object without a core system, then the application process is simpler, but the web tends to bag in the center and has uneven tension
Solution Approach 1:
A core system with handles is introduced as an intermediary tool between the applicator and the web material. The core serves as a mediator that distributes tension evenly across the web width during application, preventing bagging while maintaining a relatively simple application process.
Solution Approach 2:
The core system changes the physical parameters of the application process by providing a rigid structure with handles that maintains consistent tension force distribution. This transforms the application from an uncontrolled process to one with controlled tension parameters, achieving uniform web placement.
2Manufacturing precision
If a core system with handles is used to apply the web, then even tension is achieved, but the device complexity increases
Solution Approach 1:
The core system is segmented into distinct functional components: the core body for structural support and tension distribution, and handles for user manipulation. This segmentation allows each component to perform its specific function efficiently while keeping the overall device relatively simple.
Solution Approach 2:
The core system with handles serves multiple functions: it acts as a tensioning device, a positioning tool, and a handling aid. This multi-functionality reduces the need for separate tools, making the increased complexity worthwhile by achieving uniform web application.
3Ease of operation
If the web is wrapped loosely around the pipe, then the application is easier, but bagging and wrinkles occur in the center
Solution Approach 1:
The core system is prepared in advance with the web wrapped around it before application to the pipe. This preliminary action allows the web to be pre-tensioned and positioned correctly, preventing bagging and wrinkles during the final wrapping operation while maintaining ease of application.

AI summary
A system for applying a web around a cylindrical object with even tension containing a core having a generally cylindrical shape and a pair of handles. Each handle has an insertion area, a collar area, and a gripping area. The collar area is sandwiched between the insertion area and the gripping area and the insertion diameter is less than the inner diameter of the core at the first end and second end. The handles and core have a means for coupling meaning that the core and the insertion area of the handles do not move independently from one another.
