Solution Overview

Problem

Existing gas injection devices are limited in their ability to inject gas into containers with varying inlet diameters, as they require a specific grommet size matching the container's well diameter, making them incompatible with multiple types of pods and leading to improper gas injection.

Innovation Solution

A gas injection device with a sealing portion that can deform and an assisting member with a tapered side wall, allowing the device to adapt to different inlet diameters by sealing the periphery of the ejection portion and preventing gas leakage, ensuring proper gas injection into containers with varying inlet sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a grommet is used to seal the inlet, then gas injection is effective for a specific container type, but the device cannot be used with containers having different inlet diameters

Engineering Contradiction:
Improvegas injection effectivenessVSAvoidcompatibility with different container types
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The ejection portion is designed with a universal structure that can accommodate multiple container types with different inlet diameters. By eliminating the container-specific grommet and using a flexible sealing portion that adapts to various diameters, the gas injection device achieves multi-functionality across different FOUP designs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The sealing mechanism transitions from a fixed-parameter grommet to a variable-parameter sealing portion that can change its effective sealing diameter. The flexible material and geometric design allow the sealing portion to adapt its dimensions to match different inlet diameters, enabling the same device to work reliably across varying container specifications.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If a fixed-size grommet is used for sealing, then the sealing structure is simple, but it cannot adapt to varying inlet diameters of different containers

Engineering Contradiction:
Improvesealing structure simplicityVSAvoidcompatibility with different inlet diameters
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The sealing portion is constructed from flexible material that can deform and conform to different inlet diameters. This flexible membrane structure replaces the rigid, fixed-size grommet, allowing the sealing interface to adapt to various container types while maintaining a relatively simple overall device structure.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The sealing portion incorporates dynamic adaptability through its flexible geometry and material properties. Rather than a static, fixed-dimensional seal, the sealing portion can dynamically adjust its effective sealing perimeter to match the specific inlet diameter of the container being used.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the ejection portion contacts the inlet for sealing, then gas injection is effective, but it cannot seal larger diameter inlets properly

Engineering Contradiction:
Improvegas injection effectivenessVSAvoidability to seal different inlet sizes
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The sealing function is segmented from the ejection portion into a separate sealing portion. This segmentation allows the ejection portion to maintain its gas injection function while the sealing portion independently adapts to different inlet diameters through its flexible, geometric design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sealing portion acts as an intermediary between the ejection portion and the container inlet. It mediates the sealing function by conforming to the inlet diameter, allowing the ejection portion to effectively inject gas without directly contacting or being constrained by the varying inlet dimensions.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A gas injection device a placement portion on which a first or second container is placed, an ejection portion which is placed on the placement portion and ejects a purge gas, and a sealing portion protruding from the placement portion so as to surround a periphery of the ejection portion. The ejection portion, with the purge gas being injected into an inlet of the second container, does not come in contact with the inlet. The sealing portion, with the purge gas being injected into an inlet of the FOUP, does not impede the contact between the ejection portion and the inlet.
