Rotating Respiratory Mask Cleaning Device with Pivoting Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for treating respiratory protective masks are complicated to use, often result in incomplete cleaning due to inadequate accessibility for the spray jet, and can lead to mask damage from improper assembly and connection methods.
Innovation Solution
A device with rotatable holding devices featuring a U-shaped retaining bracket that is pivotally movable and fixable, allowing easy and secure placement of masks on a support plate, ensuring the outer side remains accessible for cleaning and the inner side for detergent application, with optional features like a small parts container and lever mechanism for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotatable holding device with U-shaped retaining bracket is used, then the ease of operation and security of mask placement is improved, but the device complexity increases
Solution Approach 1:
The holding device is segmented into distinct functional components: a support plate for mask placement, a U-shaped retaining bracket for securing, and a pivot mechanism for adjustment. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity.
Solution Approach 2:
The retaining bracket is designed to be pivotally movable relative to the support plate, transitioning between a first position for securing the mask and a second position for releasing it. This dynamic mechanism simplifies operation by allowing easy attachment and detachment without complex locking systems.
2Reliability
If the mask is secured firmly during treatment, then the reliability of treatment application is improved, but the risk of mask damage increases
Solution Approach 1:
The U-shaped retaining bracket applies localized pressure through its angled legs that contact the mask at specific points, providing sufficient securing force for reliable treatment application while avoiding excessive pressure that could damage the mask material. The distribution of contact points optimizes this balance.
Solution Approach 2:
The design anticipates potential damage by distributing the securing force across multiple contact points and using a pivot mechanism that allows controlled movement, preventing stress concentration that could lead to mask damage during the treatment process.
3Productivity
If the spray jet has good accessibility to the mask outer side, then the cleaning effectiveness is improved, but the device complexity increases
Solution Approach 1:
The holding device positions the mask in a specific orientation on the support plate, with the U-shaped retaining bracket arranged to expose the outer side of the mask to the spray jet. This spatial arrangement in a different dimension allows effective cleaning without requiring complex positioning mechanisms.
