Transparent Shield for Reactor Chamber Pollutant Containment

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current methods for cleaning reactor chambers in pump exhaust abatement systems often release pollutants into the environment during the cleaning process, requiring protective gear and a second observer due to safety concerns.

Innovation Solution

A transparent protective shield with apertures and glove mounts is temporarily mounted on the cabinet door, allowing gloved access while containing pollutants within the cabinet, eliminating the need for special protective clothing and a second observer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the reactor chamber is opened for cleaning without protective shielding, then the technician can access the chamber to remove pollutants, but pollutants are released into the environment and technician safety is compromised

Engineering Contradiction:

Improveaccess to reactor chamberVSAvoidpollutant release and safety hazards

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A transparent protective shield is introduced as an intermediary between the technician and the reactor chamber interior. The shield allows visual observation and manual access through integrated gloves while maintaining a sealed barrier that prevents pollutant release, thus mediating between the need for chamber access and the need for pollution containment

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The protective shield incorporates flexible transparent materials that allow the technician to reach through and manipulate tools while maintaining the integrity of the containment barrier. The flexible nature of the shield material enables hand and tool passage while preserving the seal

Inventive Principle:

Principle #30Flexible shells and thin films

2Reliability

If special protective gear and a second observer are required for cleaning, then technician safety is ensured, but the complexity and time required for the cleaning operation increases

Engineering Contradiction:

Improvetechnician safetyVSAvoidprotective gear and observer requirements

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The protective shield system is designed to be self-contained and self-protecting. The integrated gloves and sealed barrier automatically protect the technician without requiring additional protective clothing or a second observer, making the safety system self-sufficient and reducing operational complexity

Inventive Principle:

Principle #25Self-service

3Loss of substance

If the reactor chamber is cleaned by scraping and bagging pollutants, then accumulated pollutants are removed, but tungsten dust spills out into the environment

Engineering Contradiction:

Improvepollutant removalVSAvoiddust spillage into environment

Core Design Contradiction:

Loss of substanceVSObject-generated harmful factors

Solution Approach 1:

The protective shield acts as an intermediary containment barrier during the pollutant removal process. Pollutants are collected and bagged within the sealed environment created by the shield, preventing dust from escaping into the surrounding environment while allowing the cleaning technician to work inside the protected zone

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A system and a method are disclosed for cleaning a reactor chamber of a pump exhaust abatement system. During the cleaning of the reactor chamber a transparent protective shield is temporarily mounted on an opening of a cabinet that contains the reactor chamber. The transparent protective shield has apertures and associated glove mounts that allow protective gloves to be placed through the apertures. This allows a technician to have gloved access to clean the reactor chamber within the cabinet. The transparent protective shield protects the technician from exposure to pollutants during the time that the reactor chamber is being cleaned. The transparent protective shield is removed after the cleaning process has been completed.
