Flat Panel Detector Wrap Replacing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current method for replacing the outer plastic bag of a Flat Panel Detector (FPD) used in portable X-ray apparatuses requires two operators and is cumbersome due to the need for caution and attention to prevent infection.
Innovation Solution
A wrap replacing apparatus that automatically peels off the used bag from the FPD and wraps it in a new sterilized bag, reducing the need for manual handling and allowing single-operator operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual replacement of the outer plastic bag is performed by two operators to prevent infection, then the reliability of infection prevention is improved, but the device complexity and operational difficulty increase
Solution Approach 1:
The FPD itself performs the bag replacement function through its grooves that guide the peeling process. The detector automatically separates the first bag from itself during the replacement operation, eliminating the need for complex manual handling procedures and reducing operational complexity while maintaining infection prevention reliability
Solution Approach 2:
Grooves are introduced as intermediary structures on the FPD that mediate the bag replacement process. These grooves guide the separation of the first bag and facilitate the peeling action, providing a structured interface that simplifies the replacement operation while ensuring reliable infection prevention
2Productivity
If manual handling is used to replace the plastic bag, then flexibility in operation is maintained, but the time required for replacement increases
Solution Approach 1:
The grooves are pre-formed on the FPD surface before the bag replacement operation. These pre-existing grooves guide the bag separation process from the outset, enabling faster and more efficient replacement by eliminating the need for gradual, cautious manual peeling and directly improving replacement speed while reducing time loss
3Reliability
If cautious manual operation is performed to avoid contamination, then the reliability of contamination prevention is improved, but the ease of operation deteriorates
Solution Approach 1:
The FPD surface is segmented with grooves that divide and guide the bag separation process. This segmentation provides clear pathways for the first bag to be peeled away, making the operation easier to perform while maintaining reliable contamination prevention through the structured separation path
Solution Approach 2:
The FPD's grooved structure enables the detector to guide its own bag replacement process. The grooves automatically direct the peeling action and separate the first bag from the detector surface, eliminating the need for cautious manual manipulation while ensuring reliable contamination prevention through the self-guided process
