Bladder Pulling Apparatus with Resistance-Activated Slit Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing an inflatable bladder from a chamber through an aperture often fail to completely deflate the bladder, leading to gas accumulation and potential rupture during the pulling process, which can result in undesirable gas mixing.
Innovation Solution
An apparatus with a cutting device that creates a slit in the bladder when resistance exceeds a predetermined level during pulling, controlling gas release and maintaining a sealing effect, while a control device adjusts the pulling rate to manage resistance and prevent rupture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bladder is pulled through the aperture without controlled gas release, then the pulling process is simpler, but gas accumulates inside the bladder causing potential rupture and gas mixing
Solution Approach 1:
A cutting device is positioned in advance to create a slit in the bladder wall before the bladder is fully pulled through the aperture. This preliminary action allows controlled gas release during the pulling process, preventing gas accumulation and rupture while maintaining operational simplicity
Solution Approach 2:
A controlled slit is created in the bladder wall to act as an intermediary pathway for gas release. This mediator allows gradual gas escape during pulling, balancing the need for simple operation with maintaining gas containment integrity
2Productivity
If the pulling rate is increased to improve productivity, then the removal process is faster, but resistance increases causing gas accumulation and rupture risk
Solution Approach 1:
The cutting device creates a slit in advance before high-speed pulling begins. This preliminary gas pathway enables faster pulling rates by preventing pressure buildup, thus improving productivity without increasing rupture risk
Solution Approach 2:
Gas is extracted from the bladder through the controlled slit during the pulling process. This extraction mechanism allows higher pulling speeds by continuously removing gas that would otherwise accumulate and increase internal pressure
3Object-affected harmful factors
If the bladder is completely deflated before pulling, then gas mixing is prevented, but the deflation process becomes more complex and time-consuming
Solution Approach 1:
Gas is extracted through a controlled slit created during the pulling process itself. This integrates gas removal with the pulling operation, preventing gas mixing without requiring separate deflation equipment or procedures
Solution Approach 2:
The gas release function and pulling operation are merged into a single integrated process. The cutting device creates a slit that enables gas escape during pulling, combining two functions (gas management and bladder removal) into one operation

AI summary
An apparatus (1) and a method for controlling a pulling of an inflatable bladder (B) through an aperture (3) in a wall between a chamber (5) and a structure (7) arranged on an out-side of the chamber (5), wherein the apparatus (1) comprises: - a pulling mechanism (11, 11') for pulling the bladder (B) through the aperture (3); - a cutting device (13) for providing a slit in a portion of the bladder (B) after said portion having passed the aperture (3), the cutting device (13) being responsive to a resistance of the bladder (B) against passing through the aperture (3), so that the cutting device (13) is activated and provides the slit if the resistance exceeds a predetermined level.
