Material Sheet Wrapping Carriage for Consistent Tension Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for wrapping material sheets around longitudinal components, such as pressurized rubber bladders used in airplane manufacturing, are manual and time-consuming, often resulting in inconsistent tension application and the formation of wrinkles.
Innovation Solution
A material wrapping system comprising a movable carriage with side and top wheels that guide a material sheet around a longitudinal component, utilizing a tensioning dispenser to maintain tension and a positional lock to secure the system, allowing for automated and consistent wrapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual wrapping methods are used, then the process is simple to implement, but the wrapping speed is slow and labor-intensive
Solution Approach 1:
The wrapping system is divided into distinct functional modules: a movable carriage for guiding the material sheet, a tensioning dispenser for maintaining consistent tension, and a positional lock for securing the system. This segmentation allows each component to perform its specific function efficiently, thereby increasing overall wrapping speed while keeping individual components relatively simple.
Solution Approach 2:
The movable carriage is designed to automatically guide the material sheet around the longitudinal component as it moves along the track system. The tensioning dispenser automatically maintains tension on the material sheet during the wrapping process, reducing the need for manual intervention and increasing productivity.
2Manufacturing precision
If manual wrapping methods are used, then the equipment requirement is low, but the tension application is inconsistent and causes wrinkles
Solution Approach 1:
The tensioning dispenser is configured to apply tension to the material sheet before and during the wrapping process. This preliminary tensioning prevents wrinkles from forming as the material sheet is guided around the longitudinal component, ensuring consistent tension application and improving manufacturing precision.
Solution Approach 2:
The system incorporates a positional lock that secures the tensioning dispenser at specific locations along the track system. This feedback mechanism ensures that the tensioning force is applied at consistent intervals and positions, maintaining uniform tension throughout the wrapping process and preventing wrinkles.
3Productivity
If automated wrapping system is implemented, then the wrapping efficiency is improved, but the device complexity increases
Solution Approach 1:
The movable carriage serves multiple functions: it guides the material sheet around the longitudinal component, maintains positioning through the track system, and works in conjunction with the tensioning dispenser. This multi-functionality reduces the need for separate dedicated components, thereby improving wrapping efficiency while limiting the increase in overall device complexity.
Solution Approach 2:
The track system acts as an intermediary between the movable carriage and the tensioning dispenser, providing a structured pathway that coordinates their movements. This intermediary mechanism allows the automated system to function efficiently while maintaining a relatively simple overall structure, as the track system integrates multiple functions into a single framework.

AI summary
A material wrapping system is presented. The material wrapping system comprises a material sheet tensioning dispenser comprising a positional lock configured to lock the material wrapping system relative to a track system, a material roll support, and a tensioning system configured to selectively prevent rotation of a material roll on the material roll support; and a movable carriage configured to wrap a material sheet dispensed from the material roll around a longitudinal component using side wheels and top wheels configured to guide the material sheet against the longitudinal component as the movable carriage moves towards the material sheet tensioning dispenser.
