Cassette Support for Storage Phosphor Plate Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cassettes for storage phosphor plates have complex mechanisms for removing the plates, which can lead to accidental falling when the closure flap is open, especially when the cassette is positioned aslant or vertically.
Innovation Solution
A simpler cassette design featuring a support with a leaf spring fixing element that secures the storage phosphor plate within the cassette and releases it when partially outside, allowing for easy removal and conveyance using powered carrier rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex mechanism with movable support and guide elements is used to remove the storage phosphor plate, then the plate can be removed from the cassette, but the structure becomes complex and the plate may still fall out when the closure flap is open
Solution Approach 1:
The support is extracted from the complex internal mechanism and simplified to a removable tray that can be easily taken out of the cassette housing. This extraction eliminates the need for complex guide elements and slide-bearings, while the support itself incorporates a simple fixing element that releases when the support is removed, allowing the plate to be easily taken from the support outside the cassette.
Solution Approach 2:
The fixing element on the support automatically secures the storage phosphor plate when the support is inside the cassette housing, and automatically releases the plate when the support is removed from the housing. This self-service mechanism eliminates the need for additional complex release mechanisms or manual operations, resolving the contradiction between ease of operation and device complexity.
2Ease of operation
If the closure flap is kept open for easy access, then operation is simplified, but the storage phosphor plate may fall out when the cassette is positioned aslant or vertically
Solution Approach 1:
The fixing element on the support automatically secures the storage phosphor plate when the support is inside the cassette housing, regardless of whether the closure flap is open or closed. This self-service mechanism ensures reliable plate retention during transport or positioning at any angle, while the closure flap can remain open for easy access, thus resolving the contradiction between ease of operation and reliability.
3Reliability
If a movable support with fixing elements is used to prevent plate falling, then plate retention is improved, but the removal mechanism becomes more complex
Solution Approach 1:
The support is extracted from the complex internal mechanism and simplified to a removable tray that can be easily taken out of the cassette housing. This extraction eliminates the need for complex guide elements and slide-bearings, while the support itself incorporates a simple fixing element that releases when the support is removed, allowing the plate to be easily taken from the support outside the cassette.
Solution Approach 2:
The fixing element on the support automatically secures the storage phosphor plate when the support is inside the cassette housing, and automatically releases the plate when the support is removed from the housing. This self-service mechanism eliminates the need for additional complex release mechanisms or manual operations, resolving the contradiction between ease of operation and device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies the removal process, prevents accidental falling of the storage phosphor plate, and facilitates easy transfer to a read-out device, enhancing operational efficiency and safety.
Implementation Method 1
fixing element which fixes the storage phosphor plate in place on the support when the support is located, with the storage phosphor plate lying on top of it, within the cassette housing. At the same time, the fixing element releases the storage phosphor plate when the support is located, with the storage phosphor plate lying on top of it, at least partially outside of the cassette housing
Implementation Method 2
conveyed to a read-out device by means of powered carrier rollers or similar

AI summary
A cassette (1) for a storage phosphor plate (2) comprises a cassette housing (4) with an opening (7) and a support (3) disposed movably within the cassette housing (4), wherein the storage phosphor plate (2) lies on the support (3). In order to simplify the structure of the cassette (1) and of the corresponding removal mechanism, provision is made such that the support (3) can be moved, together with the storage phosphor plate (2) lying on top of it, through the opening (7) of the cassette housing (4), at least partially from the inside of the cassette housing (4), and the storage phosphor plate (2) lying on the support (3) can be taken from the support (3) when the support (3) is located, with the storage phosphor plate (2) lying on top of it, at least partially outside of the cassette housing (4).
