Elastomeric Stop With Air Channels For Flexible Pouch Depressurization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of laminated glass processing ladles with flexible walls is complex and time-consuming, requiring multiple assembly steps and increasing costs and the risk of errors due to the use of metal springs and elastomeric materials, which complicates the integration of depressurization means.
Innovation Solution
A cylindrical abutment with air circulation channels is introduced, allowing for easier assembly and integration of depressurization means without the need for additional metal components, facilitating the manufacturing process by providing a support surface for the edge of the coin and forming a longitudinal vacuum channel in fluid communication with the air circulation channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metal springs and elastomeric materials are used for depressurization means, then the depressurization function is achieved, but the manufacturing complexity and assembly time increase
Solution Approach 1:
The patent combines the support function and depressurization function into a single integrated stop component. The stop includes air circulation channels built-in during manufacturing, eliminating the need for separate metal springs and elastomeric materials. This merging of functions reduces the number of components and simplifies the manufacturing process while maintaining reliable depressurization.
Solution Approach 2:
The stop serves multiple functions simultaneously: it supports the edge of the part introduced into the bag, provides air circulation channels for depressurization, and acts as a structural element of the bag. This multi-functionality eliminates the need for separate depressurization mechanisms, reducing manufacturing complexity while achieving reliable depressurization.
2Strength
If metal components are used in air circulation openings, then structural support is provided, but the manufacturing steps and risk of error increase
Solution Approach 1:
The stop is made entirely of elastomeric material, creating a homogeneous structure that is consistent with the rest of the bag material. This eliminates the need to assemble different materials (metal and elastomer) and reduces manufacturing complexity. The homogeneous elastomeric structure provides sufficient structural support while simplifying the manufacturing process.
Solution Approach 2:
The patent uses elastomeric material with integrated air circulation channels to create a composite structure that combines structural support and fluid circulation functions. This composite approach eliminates metal components while maintaining structural integrity and providing the necessary support for the bag's operation.
3Reliability
If multiple assembly steps are used for integrating depressurization means, then the depressurization system is assembled, but the manufacturing time and costs increase
Solution Approach 1:
The air circulation channels are built into the stop during its manufacturing process, before the stop is assembled into the bag. This preliminary action eliminates the need for additional assembly steps to install depressurization components, as the channels are already formed and ready for operation. The stop is manufactured independently with channels integrated, then simply assembled into the bag.
4Reliability
If care is taken to avoid blocking air circulation openings during cross-linking, then the depressurization function is preserved, but the manufacturing process becomes more complex
Solution Approach 1:
The stop is made of elastomeric material that can be cross-linked together with the bag material in a single process. The air circulation channels are built-in and protected by the elastomeric structure itself, eliminating the need for separate protective measures like metal combs. The material itself serves to protect and maintain the channel openings during cross-linking.

AI summary
The present invention relates to a stop (1) for a pouch with flexible walls, the pouch being configured to be depressurised by means of a longitudinal depressurisation means in fluid communication with an interior volume of the pouch. The stop has a longitudinal shape and comprises at least: - a first longitudinal surface (4) intended to delimit or be in contact with at least a portion of the depressurisation means, - a second longitudinal surface (6) remote from the first longitudinal surface (4) and being intended to form a bearing surface for the edge of the workpiece inserted into the pouch, and - air circulation channels (12) between the first longitudinal surface (4) and the second longitudinal surface (6). The present invention also relates to a pouch with flexible walls comprising such a stop, as well as methods of manufacturing a corresponding stop and pouch.
