Screen cover device for an air-cleaning device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-cleaning devices in sensitive environments face challenges in maintaining sterility due to the risk of contamination from direct contact with non-sterile parts, necessitating improved disposable screen covers that enhance user-friendliness and sterility.
Innovation Solution
A screen cover device with a first unit to hold unused disposable screen covers and a second unit to collect used ones, integrated with an air-cleaning device, allowing seamless replacement and sterilization, featuring a germicidal radiation source for additional disinfection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single use screen cover is provided over the screen, then sterility is improved, but the device complexity increases due to manual replacement requirements
Solution Approach 1:
The system performs automatic screen cover replacement without requiring manual intervention. The robot manipulator automatically removes used screen covers from the screen and installs new disposable screen covers, enabling the system to service itself and eliminating the need for manual replacement operations.
Solution Approach 2:
The patent replaces the manual mechanical replacement process with an automated robotic system. The robot manipulator uses mechanical arms and grippers to handle screen cover removal and installation, substituting human hands and manual operations with automated mechanical systems that can perform the task more precisely and consistently.
2Reliability
If multiple disposable screen covers are stored separately, then sterility is maintained, but the ease of operation decreases due to manual handling requirements
Solution Approach 1:
Multiple disposable screen covers are combined into a single integrated storage unit with multiple compartments. This merging approach allows the system to store multiple sterile screen covers in one organized location, enabling the robot manipulator to automatically select and retrieve individual covers without requiring manual handling or searching through separate storage locations.
Solution Approach 2:
The storage unit is designed to work seamlessly with the automated robotic system, allowing the robot to automatically access, select, and retrieve the appropriate screen cover from the storage unit without human intervention. This self-service mechanism maintains sterility while eliminating manual handling operations.
3Productivity
If used screen covers are manually removed and disposed, then productivity is reduced, but the ease of manufacture increases with simple collection methods
Solution Approach 1:
The system automatically collects and disposes of used screen covers through the robot manipulator, which removes used covers from the screen and places them into a collection container. This automated self-service approach eliminates the need for manual removal and disposal operations, significantly improving productivity while the collection container design remains relatively simple in structure.
Solution Approach 2:
The system implements an automated process for discarding used screen covers and recovering them in a designated collection container. The robot manipulator efficiently transfers used covers from the screen to the collection container, enabling rapid disposal while maintaining a simple collection system that does not require complex processing or recovery mechanisms.
