Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing methods for transferring personnel and equipment between controlled atmosphere enclosures are time-consuming, labor-intensive, and prone to contamination, as they require operators to undress, move through ambient air, and re-dress in protective gear, which increases the risk of environmental contamination.

Innovation Solution

A transport installation with a traffic lane connecting enclosures, a longitudinally moving cabin with airtight openings, and a sealed tunnel formation mechanism that filters air before access door opening, maintaining a controlled atmosphere during transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If operators use airlocks with protective equipment for transfer between enclosures, then contamination risk is reduced, but transfer time and operator fatigue increase significantly

Engineering Contradiction:

Improvecontamination riskVSAvoidtransfer time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

A cabin serves as an intermediary transport vehicle between enclosures. The cabin travels along a traffic lane connecting multiple enclosures, providing a sealed environment that maintains controlled atmosphere while transferring operators and equipment without requiring them to exit to ambient air or undergo repeated dressing/undressing cycles

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The cabin is pre-equipped with filtration means and airtight closing mechanisms before transfer. The airtight opening with closing means is prepared in advance, and filtration systems are activated to maintain controlled atmosphere throughout the transfer journey, eliminating the need for post-transfer contamination control measures

Inventive Principle:

Principle #10Preliminary action

2Reliability

If operators remove protective equipment in airlocks before moving to next enclosure, then contamination is minimized, but the process becomes tedious and time-consuming

Engineering Contradiction:

Improvecontamination controlVSAvoidoperational simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The cabin maintains a continuous controlled atmosphere environment throughout the transfer journey. Operators remain in their protective equipment throughout the entire transfer process without interruption, as the cabin's sealed environment and filtration system continuously maintain atmospheric control, eliminating the need to remove and re-don protective gear

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If multiple airlocks are used for transfer between distant enclosures, then contamination risk is reduced, but the complexity and duration of the transfer process increase

Engineering Contradiction:

Improvecontamination riskVSAvoidtransfer process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The cabin serves multiple functions: it acts as a sealed transfer vehicle, maintains controlled atmosphere through integrated filtration, provides protected transport for both operators and equipment, and connects multiple enclosures along a single traffic lane. This multi-functional design replaces the need for multiple separate airlock systems

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The traffic lane provides a dedicated third dimension for transfer operations, separate from the enclosure interiors. The cabin travels along this external lane connecting enclosures, creating a parallel transfer pathway that avoids the need for operators to navigate through multiple airlock chambers and ambient air corridors

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

The invention relates to equipment for the conveyance between at least two controlled atmosphere chambers (10), comprising a circulation path (13) connecting the chambers (10) and extending along the outside of each chamber (10) and along the access door (11) thereof. At least one cabin (14) moves on the circulation path (13) so as to assume a series of parking positions in front of the chambers (10). Means temporarily define, in each parking position, a sealed tunnel connecting the cabin (14) and the access door (11) of the housing (10) corresponding to said parking position. Means installed onboard the cabin are used for filtering the air inside the cabin (14).
