Segmented Sealing Structure for Inflatable Gas Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inflatable structures for packaging suffer from gas leakage through air introducing channels, which reduces their effectiveness in buffering external forces and protecting goods during transportation.
Innovation Solution
A sealing structure comprising a first inner layer unit, a second inner layer unit, a first outer layer unit, and a second outer layer unit, with a gas delivery structure that includes stop barriers and a runner, forming retention spaces to prevent gas leakage by creating a closed system for gas storage and delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gas is introduced into inflatable structures through air introducing channels, then the inflatable structures can be inflated to provide buffering effect, but gas leakage occurs through the same channels reducing the buffering effectiveness
Solution Approach 1:
The sealing structure divides the channel system into multiple segments with alternating connection patterns. The first and second outer layer units are connected to the first and second inner layer units respectively through non-continuous patterns at different positions, creating segmented sealing zones that prevent continuous gas leakage paths while allowing controlled gas delivery to inflatable regions.
Solution Approach 2:
The runner acts as an intermediary component between the supply channel and the inflatable structures. It receives gas from the supply channel formed by the outer layer units and distributes it to the gas storing spaces, while the stop barriers serve as intermediaries to control and limit gas flow, preventing backflow and leakage through the supply channel.
2Loss of substance
If the sealing structure uses multiple layer units with complex connection patterns to prevent gas leakage, then gas leakage is reduced, but the device complexity increases
Solution Approach 1:
The sealing structure merges the sealing functions into a single integrated multi-layer unit comprising first and second inner layer units, first and second outer layer units, and a runner. These components work together as one unified structure with non-continuous connection patterns that achieve effective sealing without requiring multiple separate sealing mechanisms.
Solution Approach 2:
The non-continuous connection patterns between outer layer units and inner layer units provide sufficient sealing action at critical positions without requiring complete coverage throughout the entire structure. The stop barriers are positioned at specific locations within the runner to provide adequate gas flow control without excessive structural complexity.
