Removable Cover for Plasma Cleaning Surface Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plasma cleaning treatments struggle to achieve high cleanliness levels due to contamination from objects with varying surface contamination levels, risking contamination of the plasma cleaning device and requiring manual cleaning of subassemblies and packing materials.
Innovation Solution
An object with a removable cover is designed to separate surfaces with different contamination levels, allowing the plasma cleaning device to clean only the lower-contamination surface while keeping the higher-contamination surface isolated, preventing contamination of the device and reducing manual cleaning steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional plasma cleaning treatment is applied to objects with different contamination levels, then the cleaning process can be performed, but the plasma cleaning device becomes contaminated and requires manual cleaning of subassemblies and packing material
Solution Approach 1:
The object is divided into multiple parts with different contamination levels. The first part (object proper) has lower contamination and is suitable for plasma cleaning, while the second part (packing material or subassemblies) has higher contamination and is excluded from the plasma cleaning chamber using a cover or separate containment, preventing contamination spread to the device
Solution Approach 2:
The highly contaminated second part is extracted or separated from the plasma cleaning process. A removable cover or barrier is used to exclude the high-contamination packing material from the plasma cleaning chamber, allowing the plasma treatment to proceed on the object without exposing the device to harmful contaminants
2Reliability
If manual cleaning of subassemblies and packing material is performed separately, then high cleanliness levels can be achieved, but the process time increases significantly
Solution Approach 1:
The object structure itself facilitates the cleaning process by allowing the plasma cleaning device to effectively clean the first part while the second part is automatically excluded. The removable cover design enables automatic separation of cleanable and non-cleanable areas, reducing the need for time-consuming manual intervention
Solution Approach 2:
The object is prepared in advance with a structure that accommodates differential contamination levels. The removable cover is designed to be in place before plasma cleaning, pre-configuring the system to protect sensitive areas and allowing the plasma process to proceed without interruption for manual cleaning
3Reliability
If the object is disassembled and reassembled multiple times for cleaning, then contamination risk is reduced, but the number of handling steps increases and new contamination risks arise
Solution Approach 1:
The object is segmented into a first part that requires plasma cleaning and a second part that does not, with a removable cover providing the separation. This segmentation allows the cleaning process to proceed without full disassembly, reducing handling steps while maintaining contamination control
Solution Approach 2:
A removable cover (flexible barrier) is used to separate areas with different contamination levels during the plasma cleaning process. This flexible shielding approach allows the object to remain assembled while protecting sensitive areas, eliminating the need for disassembly and reassembly operations

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach significantly reduces the risk of contamination for the plasma cleaning device and the object, streamlining the cleaning process by minimizing the number of handling steps and ensuring higher cleanliness without exposing the device to high-contamination surfaces.
Implementation Method 1
Such an energetic plasma may be created while ionizing a low pressure gas phase
Implementation Method 2
an energetic plasma created from gaseous species
Implementation Method 3
The energetic, ionic gaseous species react with impurities and contaminants on the surface area of the object to be cleaned, often producing gaseous products
Implementation Method 4
The energetic species also clean the surface area by collision with the surface area, knocking off the impurities and contaminants from the surface area
