Medical Cassette Holder Structure for Safe Immersion and Block Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cassette holders for medical use require cumbersome detachment of the lid body after paraffin solidification and involve manual immersion in chemical liquid, leading to low workability and safety concerns.
Innovation Solution
A cassette holder with a plate-shaped portion extending parallel to the bottom surface, allowing safe immersion without touching the cassette, and slits for easy folding and retrieval, along with projections for secure bottle attachment, ensuring easy handling and prevention of rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lid body is attached to the cassette body to prevent detachment during chemical liquid immersion, then the reliability of the cassette assembly is improved, but the ease of operation deteriorates because the lid body must be detached after paraffin solidification
Solution Approach 1:
The cassette holder is divided into separate components: a cassette receiving portion and a plate-shaped portion that can be detached. This allows the cassette to remain securely held during processing while enabling easy removal of the entire assembly for block retrieval without detaching individual components like a lid body.
Solution Approach 2:
The plate-shaped portion acts as an intermediary handling element. Instead of directly touching or manipulating the cassette body and lid body, the operator grips the plate-shaped portion which extends parallel to the bottom surface, providing a safe and easy-to-grip interface for immersion and retrieval operations.
2Device complexity
If manual immersion in chemical liquid is performed, then the simplicity of the procedure is maintained, but the ease of operation deteriorates due to safety concerns and cumbersome handling
Solution Approach 1:
The plate-shaped portion serves as an intermediary that allows safe handling during chemical liquid immersion. The plate extends parallel to the bottom surface and can be gripped without touching the cassette itself, providing a safe interface that maintains procedural simplicity while eliminating safety concerns associated with direct manual handling.
Solution Approach 2:
The cassette holder design allows the cassette to be self-contained and safely handled through the plate-shaped portion. The holder structure itself provides the handling mechanism, eliminating the need for external tools or complex manipulation procedures while maintaining safety.
3Ease of operation
If the cassette holder is designed with a plate-shaped portion extending parallel to the bottom surface, then the ease of operation is improved for safe immersion without touching the cassette, but the device complexity increases
Solution Approach 1:
The plate-shaped portion serves multiple functions: it provides a gripping surface for safe immersion, maintains structural integrity of the holder, and facilitates easy retrieval. By making this single element multi-functional, the design achieves improved ease of operation without proportionally increasing device complexity.
Solution Approach 2:
The plate-shaped portion is strategically positioned to extend parallel to the bottom surface at a specific location. This localized structural addition provides the necessary handling capability only where needed, rather than complicating the entire cassette holder structure.
4Ease of operation
If slits are provided in the cassette holder for easy folding and retrieval, then the ease of operation is improved, but the strength of the holder structure may be compromised
Solution Approach 1:
The slits divide the holder structure into separable regions that can fold relative to each other. This segmentation allows easy folding for retrieval while the slit design itself reinforces the overall structure by creating defined fold lines that maintain integrity during the folding process.
Solution Approach 2:
The slits introduce dynamic flexibility to an otherwise rigid holder structure. They allow controlled folding and deformation during retrieval operations while maintaining structural strength during normal use, as the slits are positioned to allow deformation only in specific directions.

AI summary
A cassette holder holds a cassette for medical use. It includes a cassette receiving portion that includes a bottom surface to which a lower surface of the cassette is brought into contact when the cassette is set, and a plate-shaped portion that is provided in the cassette receiving portion, has a substantially plate-like shape, and extends substantially parallel to the bottom surface, and a protrusion inside of which is hollow, the protrusion being provided to the bottom surface to protrude downward. The bottom surface and the protrusion are provided with a plurality of through holes.
